The Berlin Wall (German: Berliner Mauer, pronounced [bɛʁˌliːnɐ ˈmaʊ̯ɐ]) was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989. Construction of the wall was commenced by the German Democratic Republic (GDR, East Germany) on 13 August 1961. The Wall cut off West Berlin from surrounding East Germany, including East Berlin. The barrier included guard towers placed along large concrete walls, accompanied by a wide area (later known as the "death strip") that contained anti-vehicle trenches, beds of nails and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the "will of the people" from building a socialist state in East Germany.

GDR authorities officially referred to the Berlin Wall as the Anti-Fascist Protection Rampart (German: Antifaschistischer Schutzwall). The West Berlin city government sometimes referred to it as the "Wall of Shame", a term coined by mayor Willy Brandt in reference to the Wall's restriction on freedom of movement. Along with the separate and much longer Inner German border (IGB), which demarcated the border between East and West Germany, it came to symbolize physically the "Iron Curtain" that separated Western Europe and the Eastern Bloc during the Cold War.

Before the Wall's erection, 3.5 million East Germans circumvented Eastern Bloc emigration restrictions and defected from the GDR, many by crossing over the border from East Berlin into West Berlin; from there they could then travel to West Germany and to other Western European countries. Between 1961 and 1989, the Wall prevented almost all such emigration. During this period, over 100,000 people attempted to escape, and over 5,000 people succeeded in escaping over the Wall, with an estimated death toll ranging from 136 to more than 200 in and around Berlin.

In 1989, a series of revolutions in nearby Eastern Bloc countries—in Poland and Hungary in particular—caused a chain reaction in East Germany. In particular, the Pan-European Picnic in August 1989 set in motion a peaceful development during which the Iron Curtain largely broke, the rulers in the East came under pressure, the Berlin Wall fell and finally the Eastern Bloc fell apart. After several weeks of civil unrest, the East German government announced on 9 November 1989 that all GDR citizens could visit West Germany and West Berlin. Crowds of East Germans crossed and climbed onto the Wall, joined by West Germans on the other side in a celebratory atmosphere. Over the next few weeks, euphoric people and souvenir hunters chipped away parts of the Wall. The Brandenburg Gate, a few meters from the Berlin Wall, was opened on 22 December 1989. The demolition of the Wall officially began on 13 June 1990 and was completed in 1994. The "fall of the Berlin Wall" paved the way for German reunification, which formally took place on 3 October 1990.

Background

Post-war Germany

After the end of World War II in Europe, what remained of pre-war Germany west of the Oder-Neisse line was divided into four occupation zones (as per the Potsdam Agreement), each one controlled by one of the four occupying Allied powers: the United States, the United Kingdom, France and the Soviet Union. The capital of Berlin, as the seat of the Allied Control Council, was similarly subdivided into four sectors despite the city's location, which was fully within the Soviet zone.

Within two years, political divisions increased between the Soviets and the other occupying powers. These included the Soviets' refusal to agree to reconstruction plans making post-war Germany self-sufficient, and to a detailed accounting of industrial plants, goods and infrastructure—some of which had already been removed by the Soviets. France, the United Kingdom, the United States, and the Benelux countries later met to combine the non-Soviet zones of Germany into one zone for reconstruction, and to approve the extension of the Marshall Plan.

Eastern Bloc and the Berlin airlift

Following the defeat of Nazi Germany in World War II, the Soviet Union engineered the installation of friendly Communist governments in most of the countries occupied by Soviet military forces at the end of the War, including Poland, Hungary, Czechoslovakia, Bulgaria, Romania, and the GDR, which together with Albania formed the Comecon in 1949 and later a military alliance, the Warsaw Pact. This bloc of nations was set up by the Soviets in opposition to NATO in the capitalist West in what became the Cold War.

Since the end of the War, the Soviets together with like-minded East Germans created a new Soviet-style regime in the Soviet Zone and later the GDR, on a centrally planned socialist economic model with nationalized means of production, and with repressive police state institutions, under party dictatorship of the SED similar to the party dictatorship of the Soviet Communist Party in the USSR.

At the same time, a parallel regime was established under the strict control of the Western powers in the zones of post-war Germany occupied by them, culminating in the foundation of the Federal Republic of Germany in 1949, which initially claimed to be the sole legitimate power in all of Germany, East and West. The material standard of living in the Western zones of Berlin began to improve quickly, and residents of the Soviet Zone soon began leaving for the West in large numbers, fleeing hunger, poverty and repression in the Soviet Zone for a better life in the West. Soon residents of other parts of the Soviet Zone began to escape to the West through Berlin, and this migration, called in Germany "Republikflucht", deprived the Soviet Zone not only of working forces desperately needed for post-war reconstruction but disproportionately highly educated people, which came to be known as the "Brain Drain".

In 1948, in response to moves by the Western powers to establish a separate, federal system of government in the Western zones, and to extend the Marshall Plan to Germany, the Soviets instituted the Berlin Blockade, preventing people, food, materials and supplies from arriving in West Berlin by land routes through the Soviet zone. The United States, the United Kingdom, France, Canada, Australia, New Zealand and several other countries began a massive "airlift", supplying West Berlin with food and other supplies. The Soviets mounted a public relations campaign against the Western policy change. Communists attempted to disrupt the elections of 1948, preceding large losses therein, while 300,000 Berliners demonstrated for the international airlift to continue. In May 1949, Stalin lifted the blockade, permitting the resumption of Western shipments to Berlin.

The German Democratic Republic (the "GDR"; East Germany) was declared on 7 October 1949. On that day, the USSR ended the Soviet military government which had governed the Soviet Occupation Zone (Sowetische Besatzungszone) since the end of the War and handed over legal power to the Provisorische Volkskammer under the new Constitution of the GDR which came into force that day. However, until 1955, the Soviets maintained considerable legal control over the GDR state, including the regional governments, through the Sowetische Kontrollkommission and maintained a presence in various East German administrative, military, and secret police structures. Even after legal sovereignty of the GDR was restored in 1955, the Soviet Union continued to maintain considerable influence over administration and lawmaking in the GDR through the Soviet embassy and through the implicit threat of force which could be exercised through the continuing large Soviet military presence in the GDR, which was used to bloodily repress protests in East Germany in June 1953.

East Germany differed from West Germany (Federal Republic of Germany), which developed into a Western capitalist country with a social market economy and a democratic parliamentary government. Continual economic growth starting in the 1950s fueled a 20-year "economic miracle" ("Wirtschaftswunder"). As West Germany's economy grew, and its standard of living steadily improved, many East Germans wanted to move to West Germany.

Emigration westward in the early 1950s

After the Soviet occupation of Eastern Europe at the end of World War II, the majority of those living in the newly acquired areas of the Eastern Bloc aspired to independence and wanted the Soviets to leave. Taking advantage of the zonal border between occupied zones in Germany, the number of GDR citizens moving to West Germany totaled 187,000 in 1950; 165,000 in 1951; 182,000 in 1952; and 331,000 in 1953. One reason for the sharp 1953 increase was fear of potential further Sovietization, given the increasingly paranoid actions of Joseph Stalin in late 1952 and early 1953. 226,000 had fled in just the first six months of 1953.

Erection of the inner German border

By the early 1950s, the Soviet approach to controlling national movement, restricting emigration, was emulated by most of the rest of the Eastern Bloc, including East Germany. The restrictions presented a quandary for some Eastern Bloc states, which had been more economically advanced and open than the Soviet Union, such that crossing borders seemed more natural—especially where no prior border existed between East and West Germany.

Up until 1952, the demarcation lines between East Germany and the western occupied zones could be easily crossed in most places. On 1 April 1952, East German leaders met the Soviet leader Joseph Stalin in Moscow; during the discussions, Stalin's foreign minister Vyacheslav Molotov proposed that the East Germans should "introduce a system of passes for visits of West Berlin residents to the territory of East Berlin [so as to stop] free movement of Western agents" in the GDR. Stalin agreed, calling the situation "intolerable". He advised the East Germans to build up their border defenses, telling them that "The demarcation line between East and West Germany should be considered a border—and not just any border, but a dangerous one ... The Germans will guard the line of defence with their lives."

Consequently, the inner German border between the two German states was closed, and a barbed-wire fence erected. The border between the Western and Eastern sectors of Berlin, however, remained open, although traffic between the Soviet and the Western sectors was somewhat restricted. This resulted in Berlin becoming a magnet for East Germans desperate to escape life in the GDR, and also a flashpoint for tension between the United States and the Soviet Union.

In 1955, the Soviets gave East Germany authority over civilian movement in Berlin, passing control to a regime not recognized in the West. Initially, East Germany granted "visits" to allow its residents access to West Germany. However, following the defection of large numbers of East Germans (known as Republikflucht) under this regime, the new East German state legally restricted virtually all travel to the West in 1956. Soviet East German ambassador Mikhail Pervukhin observed that "the presence in Berlin of an open and essentially uncontrolled border between the socialist and capitalist worlds unwittingly prompts the population to make a comparison between both parts of the city, which unfortunately does not always turn out in favour of Democratic [East] Berlin."

Berlin emigration loophole

With the closing of the inner German border officially in 1952, the border in Berlin remained considerably more accessible because it was administered by all four occupying powers. Accordingly, Berlin became the main route by which East Germans left for the West. On 11 December 1957, East Germany introduced a new passport law that reduced the overall number of refugees leaving Eastern Germany.

It had the unintended result of drastically increasing the percentage of those leaving through West Berlin from 60% to well over 90% by the end of 1958. Those caught trying to leave East Berlin were subjected to heavy penalties, but with no physical barrier and subway train access still available to West Berlin, such measures were ineffective. The Berlin sector border was essentially a "loophole" through which Eastern Bloc citizens could still escape. The 3.5 million East Germans who had left by 1961 totalled approximately 20% of the entire East German population.

An important reason that passage between East Germany and West Berlin was not stopped earlier was that doing so would cut off much of the railway traffic in East Germany. Construction of a new railway bypassing West Berlin, the Berlin outer ring, commenced in 1951. Following the completion of the railway in 1961, closing the border became a more practical proposition. (See History of rail transport in Germany.)

Brain drain

The emigrants tended to be young and well-educated, leading to the "brain drain" feared by officials in East Germany. Yuri Andropov, then the CPSU Director on Relations with Communist and Workers' Parties of Socialist Countries, wrote an urgent letter on 28 August 1958 to the Central Committee about the significant 50% increase in the number of East German intelligentsia among the refugees. Andropov reported that, while the East German leadership stated that they were leaving for economic reasons, testimony from refugees indicated that the reasons were more political than material. He stated "the flight of the intelligentsia has reached a particularly critical phase."

By 1960, the combination of World War II and the massive emigration westward left East Germany with only 61% of its population of working age, compared to 70.5% before the war. The loss was disproportionately heavy among professionals: engineers, technicians, physicians, teachers, lawyers, and skilled workers. The direct cost of manpower losses to East Germany (and corresponding gain to the West) has been estimated at $7 billion to $9 billion, with East German party leader Walter Ulbricht later claiming that West Germany owed him $17 billion in compensation, including reparations as well as manpower losses. In addition, the drain of East Germany's young population potentially cost it over 22.5 billion marks in lost educational investment. The brain drain of professionals had become so damaging to the political credibility and economic viability of East Germany that the re-securing of the German communist frontier was imperative.

The exodus of emigrants from East Germany presented two minor potential benefits: an easy opportunity to smuggle East German secret agents to West Germany, and a reduction in the number of citizens hostile to the communist regime. Neither of these advantages, however, proved particularly useful.

On 15 June 1961, First Secretary of the Socialist Unity Party and GDR State Council chairman Walter Ulbricht stated in an international press conference, "Niemand hat die Absicht, eine Mauer zu errichten!" (No one has the intention of erecting a wall!). It was the first time the colloquial term Mauer (wall) had been used in this context.

The transcript of a telephone call between Nikita Khrushchev and Ulbricht, on 1 August in the same year, suggests that the initiative for the construction of the Wall came from Khrushchev. However, other sources suggest that Khrushchev had initially been wary about building a wall, fearing negative Western reaction. Nevertheless, Ulbricht had pushed for a border closure for quite some time, arguing that East Germany's very existence was at stake.

Khrushchev had become emboldened upon seeing US president John F. Kennedy's youth and inexperience, which he considered a weakness. In the 1961 Vienna summit, Kennedy made the error of admitting that the US wouldn't actively oppose the building of a barrier. A feeling of miscalculation and failure immediately afterwards was admitted by Kennedy in a candid interview with New York Times columnist James "Scotty" Reston. On Saturday, 12 August 1961, the leaders of the GDR attended a garden party at a government guesthouse in Döllnsee, in a wooded area to the north of East Berlin. There, Ulbricht signed the order to close the border and erect a wall.

At midnight, the police and units of the East German army began to close the border and, by Sunday morning, 13 August, the border with West Berlin was closed. East German troops and workers had begun to tear up streets running alongside the border to make them impassable to most vehicles and to install barbed wire entanglements and fences along the 156 kilometres (97 mi) around the three western sectors, and the 43 kilometres (27 mi) that divided West and East Berlin. The date of 13 August became commonly referred to as Barbed Wire Sunday in Germany.

The barrier was built inside East Berlin or East German territory to ensure that it did not encroach on West Berlin at any point. Generally, the Wall was only slightly inside East Berlin, but in a few places it was some distance from the legal border, most notably at Potsdamer Bahnhof and the Lenné Triangle that is now much of the Potsdamer Platz development.

Later, the initial barrier was built up into the Wall proper, the first concrete elements and large blocks being put in place on 17 August. During the construction of the Wall, National People's Army (NVA) and Combat Groups of the Working Class (KdA) soldiers stood in front of it with orders to shoot anyone who attempted to defect. Additionally, chain fences, walls, minefields and other obstacles were installed along the length of East Germany's western border with West Germany proper. A huge no man's land was cleared to provide a clear line of fire at fleeing refugees.

Immediate effects

With the closing of the east–west sector boundary in Berlin, the vast majority of East Germans could no longer travel or emigrate to West Germany. Berlin soon went from being the easiest place to make an unauthorized crossing between East and West Germany to being the most difficult. Many families were split, while East Berliners employed in the West were cut off from their jobs. West Berlin became an isolated exclave in a hostile land. West Berliners demonstrated against the Wall, led by their Mayor (Oberbürgermeister) Willy Brandt, who criticized the United States for failing to respond and went so far as to suggest to Washington what to do next. Kennedy was furious. Allied intelligence agencies had hypothesized about a wall to stop the flood of refugees, but the main candidate for its location was around the perimeter of the city. In 1961, Secretary of State Dean Rusk proclaimed, "The Wall certainly ought not to be a permanent feature of the European landscape. I see no reason why the Soviet Union should think it is—it is to their advantage in any way to leave there that monument to communist failure."

United States and UK sources had expected the Soviet sector to be sealed off from West Berlin but were surprised by how long the East Germans took for such a move. They considered the Wall as an end to concerns about a GDR/Soviet retaking or capture of the whole of Berlin; the Wall would presumably have been an unnecessary project if such plans were afloat. Thus, they concluded that the possibility of a Soviet military conflict over Berlin had decreased.

The East German government claimed that the Wall was an "anti-fascist protective rampart" (German: "antifaschistischer Schutzwall") intended to dissuade aggression from the West. Another official justification was the activities of Western agents in Eastern Europe. The Eastern German government also claimed that West Berliners were buying out state-subsidized goods in East Berlin. East Germans and others greeted such statements with skepticism, as most of the time, the border was only closed for citizens of East Germany traveling to the West, but not for residents of West Berlin travelling to the East. The construction of the Wall had caused considerable hardship to families divided by it. Most people believed that the Wall was mainly a means of preventing the citizens of East Germany from entering or fleeing to West Berlin.

Secondary response

The National Security Agency was the only American intelligence agency that was aware that East Germany was to take action to deal with the brain drain problem. On 9 August 1961, the NSA intercepted an advance warning information of the Socialist Unity Party's plan to close the intra-Berlin border between East and West Berlin completely for foot traffic. The interagency intelligence Berlin Watch Committee assessed that this intercept "might be the first step in a plan to close the border." This warning did not reach John F. Kennedy until noon on 13 August 1961, while he was vacationing in his yacht off the Kennedy Compound in Hyannis Port, Massachusetts. While Kennedy was angry that he had no advance warning, he was relieved that the East Germans and the Soviets had only divided Berlin without taking any action against West Berlin's access to the West. However, he denounced the Berlin Wall, whose erection worsened the relations between the United States and the Soviet Union.

In response to the erection of the Berlin Wall, a retired general, Lucius D. Clay, was appointed by Kennedy as his special advisor with ambassadorial rank. Clay had been the Military Governor of the US Zone of Occupation in Germany during the period of the Berlin Blockade and had ordered the first measures in what became the Berlin Airlift. He was immensely popular with the residents of West Berlin, and his appointment was an unambiguous sign that Kennedy would not compromise on the status of West Berlin. As a symbolic gesture, Kennedy sent Clay and Vice President Lyndon B. Johnson to West Berlin. They landed at Tempelhof Airport on the afternoon of Saturday, 19 August 1961 and were greeted enthusiastically by the local population.

They arrived in a city defended by three Allied brigades—one each from the UK (Berlin Infantry Brigade), the US (Berlin Brigade), and France (Forces Françaises à Berlin). On 16 August, Kennedy had given the order for them to be reinforced. Early on 19 August, the 1st Battle Group, 18th Infantry Regiment (commanded by Colonel Glover S. Johns Jr.) was alerted.

On Sunday morning, U.S. troops marched from West Germany through East Germany, bound for West Berlin. Lead elements—arranged in a column of 491 vehicles and trailers carrying 1,500 men, divided into five march units—left the Helmstedt-Marienborn checkpoint at 06:34. At Marienborn, the Soviet checkpoint next to Helmstedt on the West German-East German border, US personnel were counted by guards. The column was 160 kilometres (99 mi) long, and covered 177 kilometres (110 mi) from Marienborn to Berlin in full battle gear. East German police watched from beside trees next to the autobahn all the way along.

The front of the convoy arrived at the outskirts of Berlin just before noon, to be met by Clay and Johnson, before parading through the streets of Berlin in front of a large crowd. At 04:00 on 21 August, Lyndon Johnson left West Berlin in the hands of General Frederick O. Hartel and his brigade of 4,224 officers and men. "For the next three and a half years, American battalions would rotate into West Berlin, by autobahn, at three-month intervals to demonstrate Allied rights to the city".

The creation of the Wall had important implications for both German states. By stemming the exodus of people from East Germany, the East German government was able to reassert its control over the country: in spite of discontent with the Wall, economic problems caused by dual currency and the black market were largely eliminated. The economy in the GDR began to grow. However, the Wall proved a public relations disaster for the communist bloc as a whole. Western powers portrayed it as a symbol of communist tyranny, particularly after East German border guards shot and killed would-be defectors. Such fatalities were later treated as acts of murder by the reunified Germany.

The Berlin Wall was more than 140 kilometres (87 mi) long. In June 1962, a second, parallel fence, also known as a “hinterland” wall (inner wall), was built some 100 metres (110 yd) farther into East German territory. The houses contained between the wall and fences were razed and the inhabitants relocated, thus establishing what later became known as the death strip. The death strip was covered with raked sand or gravel, rendering footprints easy to notice, easing the detection of trespassers and also enabling officers to see which guards had neglected their task; it offered no cover; and, most importantly, it offered clear fields of fire for the Wall guards.

Through the years, the Berlin Wall evolved through four versions:

  • Wire fence and concrete block wall (1961)
  • Improved wire fence (1962–1965)
  • Improved concrete wall (1965–1975)
  • Grenzmauer 75 (Border Wall 75) (1975–1989)

The "fourth-generation Wall", known officially as "Stützwandelement UL 12.11" (retaining wall element UL 12.11), was the final and most sophisticated version of the Wall. Begun in 1975 and completed about 1980, it was constructed from 45,000 separate sections of reinforced concrete, each 3.6 metres (12 ft) high and 1.2 metres (3.9 ft) wide, and cost DDM16,155,000 or about US$3,638,000. The concrete provisions added to this version of the Wall were done to prevent escapees from driving their cars through the barricades. At strategic points, the Wall was constructed to a somewhat weaker standard, so that East German and Soviet armored vehicles could easily break through in the event of war.

This section of the Wall's "death strip" featured Czech hedgehogs, a guard tower and a cleared area, 1977.

The top of the wall was lined with a smooth pipe, intended to make it more difficult to scale. The Wall was reinforced by mesh fencing, signal fencing, anti-vehicle trenches, barbed wire, dogs on long lines, "beds of nails" (also known as "Stalin's Carpet") under balconies hanging over the "death strip", over 116 watchtowers, and 20 bunkers with hundreds of guards. This version of the Wall is the one most commonly seen in photographs, and surviving fragments of the Wall in Berlin and elsewhere around the world are generally pieces of the fourth-generation Wall. The layout came to resemble the inner German border in most technical aspects, except that the Berlin Wall had no landmines nor spring-guns. Maintenance was performed on the outside of the wall by personnel who accessed the area outside it either via ladders or via hidden doors within the wall. These doors could not be opened by a single person, needing two separate keys in two separate keyholes to unlock.

As was the case with the inner German border, an unfortified strip of Eastern territory was left outside the wall. This outer strip was used by workers to paint over graffiti and perform other maintenance on the outside of the wall Unlike the inner German border, however, the outer strip was usually no more than four meters wide, and, in photos from the era, the exact location of the actual border in many places appears not even to have been marked. Also in contrast with the inner German border, little interest was shown by East German law enforcement in keeping outsiders off the outer strip; sidewalks of West Berlin streets even ran inside it.

Despite the East German government's general policy of benign neglect, vandals were known to have been pursued in the outer strip, and even arrested. In 1986, defector and political activist Wolfram Hasch and four other defectors were standing inside the outer strip defacing the wall when East German personnel emerged from one of the hidden doors to apprehend them. All but Hasch escaped back into the western sector. Hasch himself was arrested, dragged through the door into the death strip, and later convicted of illegally crossing the de jure border outside the wall. Graffiti artist Thierry Noir has reported having often been pursued there by East German soldiers. While some graffiti artists were chased off the outer strip, others, such as Keith Haring, were seemingly tolerated.

Surrounding municipalities

Besides the sector-sector boundary within Berlin itself, the Wall also separated West Berlin from the present-day state of Brandenburg. The following present-day municipalities, listed in counter-clockwise direction, share a border with the former West Berlin:

Official crossings and usage

There were nine border crossings between East and West Berlin. These allowed visits by West Berliners, other West Germans, Western foreigners and Allied personnel into East Berlin, as well as visits by GDR citizens and citizens of other socialist countries into West Berlin, provided that they held the necessary permits. These crossings were restricted according to which nationality was allowed to use it (East Germans, West Germans, West Berliners, other countries). The best known was the vehicle and pedestrian checkpoint at the corner of Friedrichstraße and Zimmerstraße (Checkpoint Charlie), which was restricted to Allied personnel and foreigners.

Several other border crossings existed between West Berlin and surrounding East Germany. These could be used for transit between West Germany and West Berlin, for visits by West Berliners into East Germany, for transit into countries neighbouring East Germany (Poland, Czechoslovakia, Denmark), and for visits by East Germans into West Berlin carrying a permit. After the 1972 agreements, new crossings were opened to allow West Berlin waste to be transported into East German dumps, as well as some crossings for access to West Berlin's exclaves (see Steinstücken).

Four autobahns connected West Berlin to West Germany, including Berlin-Helmstedt autobahn, which entered East German territory between the towns of Helmstedt and Marienborn (Checkpoint Alpha), and which entered West Berlin at Dreilinden (Checkpoint Bravo for the Allied forces) in southwestern Berlin. Access to West Berlin was also possible by railway (four routes) and by boat for commercial shipping via canals and rivers.

Non-German Westerners could cross the border at Friedrichstraße station in East Berlin and at Checkpoint Charlie. When the Wall was erected, Berlin's complex public transit networks, the S-Bahn and U-Bahn, were divided with it. Some lines were cut in half; many stations were shut down. Three western lines traveled through brief sections of East Berlin territory, passing through eastern stations (called Geisterbahnhöfe, or ghost stations) without stopping. Both the eastern and western networks converged at Friedrichstraße, which became a major crossing point for those (mostly Westerners) with permission to cross.

Crossing

Travel orders to go to Berlin as used by U.S. forces in the 1980s.

West Germans and citizens of other Western countries could generally visit East Germany, often after applying for a visa at an East German embassy several weeks in advance. Visas for day trips restricted to East Berlin were issued without previous application in a simplified procedure at the border crossing. However, East German authorities could refuse entry permits without stating a reason. In the 1980s, visitors from the western part of the city who wanted to visit the eastern part had to exchange at least DM 25 into East German currency at the poor exchange rate of 1:1. It was forbidden to export East German currency from the East, but money not spent could be left at the border for possible future visits. Tourists crossing from the west had to also pay for a visa, which cost DM 5; West Berliners did not have to pay this fee.

West Berliners initially could not visit East Berlin or East Germany at all—all crossing points were closed to them between 26 August 1961 and 17 December 1963. In 1963, negotiations between East and West resulted in a limited possibility for visits during the Christmas season that year (Passierscheinregelung). Similar, very limited arrangements were made in 1964, 1965 and 1966.

In 1971, with the Four Power Agreement on Berlin, agreements were reached that allowed West Berliners to apply for visas to enter East Berlin and East Germany regularly, comparable to the regulations already in force for West Germans. However, East German authorities could still refuse entry permits.

East Berliners and East Germans could not, at first, travel to West Berlin or West Germany at all. This regulation remained in force essentially until the fall of the Wall, but over the years several exceptions to these rules were introduced, the most significant being:

  • Elderly pensioners could travel to the West starting in 1964
  • Visits of relatives for important family matters
  • People who had to travel to the West for professional reasons (for example, artists, truck drivers, musicians, writers, etc.)

For each of these exceptions, GDR citizens had to apply for individual approval, which was never guaranteed. In addition, even if travel was approved, GDR travellers could exchange only a very small amount of East German Marks into Deutsche Marks (DM), thus limiting the financial resources available for them to travel to the West. This led to the West German practice of granting a small amount of DM annually (Begrüßungsgeld, or welcome money) to GDR citizens visiting West Germany and West Berlin to help alleviate this situation.

Citizens of other East European countries were in general subject to the same prohibition of visiting Western countries as East Germans, though the applicable exception (if any) varied from country to country.

Allied military personnel and civilian officials of the Allied forces could enter and exit East Berlin without submitting to East German passport controls, purchasing a visa or being required to exchange money. Likewise, Soviet military patrols could enter and exit West Berlin. This was a requirement of the post-war Four Powers Agreements. A particular area of concern for the Western Allies involved official dealings with East German authorities when crossing the border, since Allied policy did not recognize the authority of the GDR to regulate Allied military traffic to and from West Berlin, as well as the Allied presence within Greater Berlin, including entry into, exit from, and presence within East Berlin.

The Allies held that only the Soviet Union, and not the GDR, had the authority to regulate Allied personnel in such cases. For this reason, elaborate procedures were established to prevent inadvertent recognition of East German authority when engaged in travel through the GDR and when in East Berlin. Special rules applied to travel by Western Allied military personnel assigned to the military liaison missions accredited to the commander of Soviet forces in East Germany, located in Potsdam.

Allied personnel were restricted by policy when travelling by land to the following routes:

Transit between West Germany and West Berlin

  • Road: the Helmstedt–Berlin autobahn (A2) (checkpoints Alpha and Bravo respectively). Soviet military personnel manned these checkpoints and processed Allied personnel for travel between the two points. Military personnel were required to be in uniform when traveling in this manner.
  • Rail: Western Allied military personnel and civilian officials of the Allied forces were forbidden to use commercial train service between West Germany and West Berlin, because of GDR passport and customs controls when using them. Instead, the Allied forces operated a series of official (duty) trains that traveled between their respective duty stations in West Germany and West Berlin. When transiting the GDR, the trains would follow the route between Helmstedt and Griebnitzsee, just outside West Berlin. In addition to persons traveling on official business, authorized personnel could also use the duty trains for personal travel on a space-available basis. The trains traveled only at night, and as with transit by car, Soviet military personnel handled the processing of duty train travelers. (See History of the Berlin S-Bahn.)
Entry into and exit from East Berlin

As with military personnel, special procedures applied to travel by diplomatic personnel of the Western Allies accredited to their respective embassies in the GDR. This was intended to prevent inadvertent recognition of East German authority when crossing between East and West Berlin, which could jeopardize the overall Allied position governing the freedom of movement by Allied forces personnel within all Berlin.

Ordinary citizens of the Western Allied powers, not formally affiliated with the Allied forces, were authorized to use all designated transit routes through East Germany to and from West Berlin. Regarding travel to East Berlin, such persons could also use the Friedrichstraße train station to enter and exit the city, in addition to Checkpoint Charlie. In these instances, such travelers, unlike Allied personnel, had to submit to East German border controls.

Defection attempts

During the years of the Wall, around 5,000 people successfully defected to West Berlin. The number of people who died trying to cross the Wall, or as a result of the Wall's existence, has been disputed. The most vocal claims by Alexandra Hildebrandt, Director of the Checkpoint Charlie Museum and widow of the Museum's founder, estimated the death toll to be well above 200. A historic research group at the Centre for Contemporary History (ZZF) in Potsdam has confirmed at least 140 deaths. Prior official figures listed 98 as being killed.

October 7, 1961. Four-year-old Michael Finder of East Germany is tossed by his father into a net held by residents across the border in West Berlin. The father, Willy Finder, then prepares to make the jump himself.

The East German government issued shooting orders (Schießbefehl) to border guards dealing with defectors, though such orders are not the same as "shoot to kill" orders. GDR officials denied issuing the latter. In an October 1973 order later discovered by researchers, guards were instructed that people attempting to cross the Wall were criminals and needed to be shot:

Do not hesitate to use your firearm, not even when the border is breached in the company of women and children, which is a tactic the traitors have often used.

Early successful escapes involved people jumping the initial barbed wire or leaping out of apartment windows along the line, but these ended as the Wall was fortified. East German authorities no longer permitted apartments near the Wall to be occupied, and any building near the Wall had its windows boarded and later bricked up. On 15 August 1961, Conrad Schumann was the first East German border guard to escape by jumping the barbed wire to West Berlin.

On 22 August 1961, Ida Siekmann was the first casualty at the Berlin Wall: she died after she jumped out of her third floor apartment at 48 Bernauer Strasse. The first person to be shot and killed while trying to cross to West Berlin was Günter Litfin, a twenty-four-year-old tailor. He attempted to swim across the Spree to West Berlin on 24 August 1961, the same day that East German police had received shoot-to-kill orders to prevent anyone from escaping.

Another dramatic escape was carried out in April 1963 by Wolfgang Engels, a 19-year-old civilian employee of the Nationale Volksarmee (NVA). Engels stole a Soviet armored personnel carrier from a base where he was deployed and drove it right into the Wall. He was fired at and seriously wounded by border guards. But a West German policeman intervened, firing his weapon at the East German border guards. The policeman removed Engels from the vehicle, which had become entangled in the barbed wire.

East Germans successfully defected by a variety of methods: digging long tunnels under the Wall, waiting for favorable winds and taking a hot air balloon, sliding along aerial wires, flying ultralights and, in one instance, simply driving a sports car at full speed through the basic, initial fortifications. When a metal beam was placed at checkpoints to prevent this kind of defection, up to four people (two in the front seats and possibly two in the boot) drove under the bar in a sports car that had been modified to allow the roof and windscreen to come away when it made contact with the beam. They lay flat and kept driving forward. The East Germans then built zig-zagging roads at checkpoints. The sewer system predated the Wall, and some people escaped through the sewers, in a number of cases with assistance from the Unternehmen Reisebüro. In September 1962, 29 people escaped through a tunnel to the west. At least 70 tunnels were dug under the wall; only 19 were successful in allowing fugitives—about 400 persons—to escape. The East Germany authorities eventually used seismographic and acoustic equipment to detect the practice. In 1962, they planned an attempt to use explosives to destroy one tunnel, but this was not carried out as it was apparently sabotaged by a member of the Stasi.

An airborne escape was made by Thomas Krüger, who landed a Zlin Z 42M light aircraft of the Gesellschaft für Sport und Technik, an East German youth military training organization, at RAF Gatow. His aircraft, registration DDR-WOH, was dismantled and returned to the East Germans by road, complete with humorous slogans painted on it by airmen of the Royal Air Force, such as "Wish you were here" and "Come back soon".

If an escapee was wounded in a crossing attempt and lay on the death strip, no matter how close they were to the Western wall, Westerners could not intervene for fear of triggering engaging fire from the 'Grepos', the East Berlin border guards. The guards often let fugitives bleed to death in the middle of this ground, as in the most notorious failed attempt, that of Peter Fechter (aged 18) at a point near Zimmerstrasse in East Berlin. He was shot and bled to death, in full view of the Western media, on 17 August 1962. Fechter's death created negative publicity worldwide that led the leaders of East Berlin to place more restrictions on shooting in public places and provide medical care for possible "would-be escapers". The last person to be shot and killed while trying to cross the border was Chris Gueffroy on 6 February 1989, while the final person to die in an escape attempt was Winfried Freudenberg who was killed when his homemade natural gas-filled balloon crashed on 8 March 1989.

The Wall gave rise to a widespread sense of desperation and oppression in East Berlin, as expressed in the private thoughts of one resident, who confided to her diary "Our lives have lost their spirit… we can do nothing to stop them."

Concerts by Western artists and growing anti-Wall sentiment

David Bowie, 1987

On 6 June 1987, David Bowie, who earlier for several years lived and recorded in West Berlin, played a concert close to the Wall. This was attended by thousands of Eastern concertgoers across the Wall, followed by violent rioting in East Berlin. According to Tobias Ruther, these protests in East Berlin were the first in the sequence of riots that led to those of November 1989. Although other factors were probably more influential in the fall of the Wall, upon his death in 2016, the German Foreign Office tweeted "Good-bye, David Bowie. You are now among #Heroes. Thank you for helping to bring down the #wall."

Bruce Springsteen, 1988

On 19 July 1988, 16 months before the Wall came down, Bruce Springsteen and the E-Street Band, played Rocking the Wall, a live concert in East Berlin, which was attended by 300,000 in person and broadcast on television. Springsteen spoke to the crowd in German, saying: "I'm not here for or against any government. I've come to play rock 'n' roll for you in the hope that one day all the barriers will be torn down". East Germany and its FDJ youth organization were worried they were losing an entire generation. They hoped that by letting Springsteen in, they could improve their sentiment among East Germans. However, this strategy of "one step backwards, two steps forwards" backfired, and the concert only made East Germans hungrier for more of the freedoms that Springsteen epitomized. While John F. Kennedy and Ronald Reagan delivered their famous speeches from the safety of West Berlin, Springsteen's speaking out against the Wall in the middle of East Berlin added to the euphoria.

David Hasselhoff, 1989

On 31 December 1989, American TV actor and pop music singer David Hasselhoff was the headlining performer for the Freedom Tour Live concert, which was attended by over 500,000 people on both sides of the Wall. The live concert footage was directed by music video director Thomas Mignone and aired on broadcast television station Zweites Deutsches Fernsehen ZDF throughout Europe. During shooting, film crew personnel pulled people up from both sides to stand and celebrate on top of the wall. Hasselhoff sang his number one hit song "Looking For Freedom" on a platform at the end of a twenty-meter steel crane that swung above and over the Wall adjacent to the Brandenburg Gate.

Comments by politicians

Complete speech by Ronald Reagan at the Brandenburg Gate, 12 June 1987. "Tear down this wall" passage begins at 11:10 into this video.

On 26 June 1963, 22 months after the erection of the Berlin Wall, U.S. President John F. Kennedy visited West Berlin. Speaking from a platform erected on the steps of Rathaus Schöneberg for an audience of 450,000 and straying from the prepared script, he declared in his Ich bin ein Berliner speech the support of the United States for West Germany and the people of West Berlin in particular:

Two thousand years ago, the proudest boast was civis romanus sum ["I am a Roman citizen"]. Today, in the world of freedom, the proudest boast is "Ich bin ein Berliner!"... All free men, wherever they may live, are citizens of Berlin, and therefore, as a free man, I take pride in the words "Ich bin ein Berliner!"

The message was aimed as much at the Soviets as it was at Berliners and was a clear statement of U.S. policy in the wake of the construction of the Berlin Wall. The speech is considered one of Kennedy's best, both a significant moment in the Cold War and a high point of the New Frontier. It was a great morale boost for West Berliners, who lived in an exclave deep inside East Germany and feared a possible East German occupation.

Former British prime minister Margaret Thatcher commented in 1982:

Every stone bears witness to the moral bankruptcy of the society it encloses.

In a speech at the Brandenburg Gate commemorating the 750th anniversary of Berlin on 12 June 1987, U.S. President Ronald Reagan challenged Mikhail Gorbachev, then the General Secretary of the Communist Party of the Soviet Union, to tear down the Wall as a symbol of increasing freedom in the Eastern Bloc:

We welcome change and openness; for we believe that freedom and security go together, that the advance of human liberty can only strengthen the cause of world peace. There is one sign the Soviets can make that would be unmistakable, that would advance dramatically the cause of freedom and peace. General Secretary Gorbachev, if you seek peace, if you seek prosperity for the Soviet Union and eastern Europe, if you seek liberalization, come here to this gate. Mr. Gorbachev, open this gate. Mr. Gorbachev, tear down this Wall!

In January 1989 GDR leader Erich Honecker predicted that the Wall would stand for 50 or 100 more years if the conditions that had caused its construction did not change.

Fall

Due to the increasing economic problems in the Eastern Bloc and the failure of the USSR to intervene in relation to the individual communist states, the brackets of the Eastern Bloc slowly began to loosen from the end of the 1980s. One example is the fall of the communist government in neighboring Poland's 1989 Polish legislative election. Also in June 1989, the Hungarian government began dismantling the electrified fence along its border with Austria (with Western TV crews present) although the border was still very closely guarded and escape was almost impossible.

The opening of a border gate between Austria and Hungary at the Pan-European Picnic on 19 August 1989, which was based on an idea by Otto von Habsburg to test the reaction of Mikhail Gorbachev, then triggered a peaceful chain reaction, at the end of which there was no longer the GDR and the Eastern Bloc had disintegrated. Because with the non-reaction of the USSR and the GDR to the mass exodus, the media-informed Eastern Europeans could feel the increasing loss of power of their governments and more and more East Germans were now trying to flee via Hungary. Erich Honecker explained to the Daily Mirror regarding the Paneuropean picnic and thus showed his people his own inaction: "Habsburg distributed leaflets far into Poland, on which the East German holidaymakers were invited to a picnic. When they came to the picnic, they were given gifts, food and Deutsche Mark, and then they were persuaded to come to the West." Then, in September, more than 13,000 East German tourists escaped through Hungary to Austria. This set up a chain of events. The Hungarians prevented many more East Germans from crossing the border and returned them to Budapest. These East Germans flooded the West German embassy and refused to return to East Germany.

The East German government responded by disallowing any further travel to Hungary but allowed those already there to return to East Germany. This triggered similar events in neighboring Czechoslovakia. This time, however, the East German authorities allowed people to leave, provided that they did so by train through East Germany. This was followed by mass demonstrations within East Germany itself. Protest demonstrations spread throughout East Germany in September 1989. Initially, protesters were mostly people wanting to leave to the West, chanting "Wir wollen raus!" ("We want out!"). Then protestors began to chant "Wir bleiben hier!" ("We are staying here!"). This was the start of what East Germans generally call the "Peaceful Revolution" of late 1989. The protest demonstrations grew considerably by early November. The movement neared its height on 4 November, when half a million people gathered to demand political change, at the Alexanderplatz demonstration, East Berlin's large public square and transportation hub. On 9 October 1989, the police and army units were given permission to use force against those assembled, but this did not deter the church service and march from taking place, which gathered 70,000 people.

The longtime leader of East Germany, Erich Honecker, resigned on 18 October 1989 and was replaced by Egon Krenz that day.

The wave of refugees leaving East Germany for the West kept increasing. By early November refugees were finding their way to Hungary via Czechoslovakia, or via the West German Embassy in Prague. This was tolerated by the new Krenz government, because of long-standing agreements with the communist Czechoslovak government, allowing free travel across their common border. However, this movement of people grew so large it caused difficulties for both countries. To ease the difficulties, the politburo led by Krenz decided on 9 November to allow refugees to exit directly through crossing points between East Germany and West Germany, including between East and West Berlin. Later the same day, the ministerial administration modified the proposal to include private, round-trip, and travel. The new regulations were to take effect the next day.

Günter Schabowski, the party boss in East Berlin and the spokesman for the SED Politburo, had the task of announcing the new regulations. However, he had not been involved in the discussions about the new regulations and had not been fully updated. Shortly before a press conference on 9 November, he was handed a note announcing the changes, but given no further instructions on how to handle the information. These regulations had only been completed a few hours earlier and were to take effect the following day, so as to allow time to inform the border guards. But this starting time delay was not communicated to Schabowski. At the end of the press conference, Schabowski read out loud the note he had been given. A reporter, ANSA's Riccardo Ehrman, asked when the regulations would take effect. After a few seconds' hesitation, Schabowski replied, "As far as I know, it takes effect immediately, without delay". After further questions from journalists, he confirmed that the regulations included the border crossings through the Wall into West Berlin, which he had not mentioned until then. He repeated that it was immediate in an interview with American journalist Tom Brokaw.

Excerpts from Schabowski's press conference were the lead story on West Germany's two main news programs that night—at 7:17 p.m. on ZDF's heute and at 8 p.m. on ARD's Tagesschau. As ARD and ZDF had broadcast to nearly all of East Germany since the late 1950s and had become accepted by the East German authorities, the news was broadcast there as well simultaneously. Later that night, on ARD's Tagesthemen, anchorman Hanns Joachim Friedrichs proclaimed, "This 9 November is a historic day. The GDR has announced that, starting immediately, its borders are open to everyone. The gates in the Wall stand open wide."

After hearing the broadcast, East Germans began gathering at the Wall, at the six checkpoints between East and West Berlin, demanding that border guards immediately open the gates. The surprised and overwhelmed guards made many hectic telephone calls to their superiors about the problem. At first, they were ordered to find the "more aggressive" people gathered at the gates and stamp their passports with a special stamp that barred them from returning to East Germany—in effect, revoking their citizenship. However, this still left thousands of people demanding to be let through "as Schabowski said we can". It soon became clear that no one among the East German authorities would take personal responsibility for issuing orders to use lethal force, so the vastly outnumbered soldiers had no way to hold back the huge crowd of East German citizens. Finally, at 10:45 p.m. on 9 November, Harald Jäger, the commander of the Bornholmer Straße border crossing yielded, allowing for the guards to open the checkpoints and allowing people through with little or no identity checking. As the Ossis swarmed through, they were greeted by Wessis waiting with flowers and champagne amid wild rejoicing. Soon afterward, a crowd of West Berliners jumped on top of the Wall, and were soon joined by East German youngsters. The evening of 9 November 1989 is known as the night the Wall came down.

Another border crossing to the south may have been opened earlier. An account by Heinz Schäfer indicates that he also acted independently and ordered the opening of the gate at Waltersdorf-Rudow a couple of hours earlier. This may explain reports of East Berliners appearing in West Berlin earlier than the opening of the Bornholmer Straße border crossing.

Thirty years after the fall of the Berlin Wall, The Guardian collected short stories from 9 November 1989 by five German writers who reflect on the day. In this, Kathrin Schmidt remembers comically: 'I downed almost an entire bottle of schnapps'.

Legacy

Remaining stretch of the Wall near Ostbahnhof in Friedrichshain called East Side Gallery, August 2006

Little is left of the Wall at its original site, which was destroyed almost in its entirety. Three long sections are still standing: an 80-metre-long (260 ft) piece of the first (westernmost) wall at the Topography of Terror, site of the former Gestapo headquarters, halfway between Checkpoint Charlie and Potsdamer Platz; a longer section of the second (easternmost) wall along the Spree River near the Oberbaumbrücke, nicknamed East Side Gallery; and a third section that is partly reconstructed, in the north at Bernauer Straße, which was turned into a memorial in 1999. Other isolated fragments, lampposts, other elements, and a few watchtowers also remain in various parts of the city.

  • The former leadership in the Schlesischen Busch in the vicinity of the Puschkinallee—the listed, twelve-meter high watchtower stands in a piece of the wall strip, which has been turned into a park, near the Lohmühleninsel.
  • The former "Kieler Eck" (Kiel Corner) on Kieler Strasse in Mitte, close to the Berlin-Spandau Schifffahrtskanal—the tower is protected as a historic monument and now surrounded on three sides by new buildings. It houses a memorial site named after the Wallopfer Günter Litfin, who was shot at Humboldthafen in August 1961. The memorial site, which is run by the initiative of his brother Jürgen Liftin, can be viewed after registration.
  • The former management office at Nieder Neuendorf, in the district of Hennigsdorf of the same name—here is the permanent exhibition on the history of the border installations between the two German states.
  • The former management station at Bergfelde, today the district of Hohen Neuendorf—The tower is located in an already reforested area of the border strip and is used together with surrounding terrain as a nature protection tower by the Deutschen Waldjugend.
  • The only one of the much slimmer observation towers (BT-11) in the Erna-Berger-Strasse also in Mitte—however, was moved by a few meters for construction work and is no longer in the original location; There is an exhibition about the wall in the area of the Potsdamer Platz in planning.

Nothing still accurately represents the Wall's original appearance better than a very short stretch at Bernauer Straße associated with the Berlin Wall Documentation Center. Other remnants are badly damaged by souvenir seekers. Fragments of the Wall were taken and some were sold around the world. Appearing both with and without certificates of authenticity, these fragments are now a staple on the online auction service eBay as well as German souvenir shops. Today, the eastern side is covered in graffiti that did not exist while the Wall was guarded by the armed soldiers of East Germany. Previously, graffiti appeared only on the western side. Along some tourist areas of the city centre, the city government has marked the location of the former Wall by a row of cobblestones in the street. In most places only the "first" wall is marked, except near Potsdamer Platz where the stretch of both walls is marked, giving visitors an impression of the dimension of the barrier system.

After the fall of the Berlin Wall, there were initiatives that they want to preserve the death strip walkways and redevelop it into a hiking and cycling area, known as Berliner Mauerweg. It is part of the initiative by the Berlin Senate since 2005.

Cultural differences

For many years after reunification, people in Germany talked about cultural differences between East and West Germans (colloquially Ossis and Wessis), sometimes described as Mauer im Kopf (The wall in the head). A September 2004 poll found that 25 percent of West Germans and 12 percent of East Germans wished that East and West should be separated again by a "Wall". A poll taken in October 2009 on the occasion of the 20th anniversary of the fall of the Wall indicated, however, that only about a tenth of the population was still unhappy with the unification (8 percent in the East; 12 percent in the West). Although differences are still perceived between East and West, Germans make similar distinctions between North and South.

A 2009 poll conducted by Russia's VTsIOM, found that more than half of all Russians do not know who built the Berlin Wall. Ten percent of people surveyed thought Berlin residents built it themselves. Six percent said Western powers built it and four percent thought it was a "bilateral initiative" of the Soviet Union and the West. Fifty-eight percent said they did not know who built it, with just 24 percent correctly naming the Soviet Union and its then-communist ally East Germany.

Wall segments around the world

Not all segments of the Wall were ground up as the Wall was being torn down. Many segments have been given to various institutions in the world. They can be found, for instance, in presidential and historical museums, lobbies of hotels and corporations, at universities and government buildings, and in public spaces in different countries of the world.

50th anniversary commemoration

On 13 August 2011, Germany marked the 50th anniversary of East Germany beginning the erection of the Berlin Wall. Chancellor Angela Merkel joined with President Christian Wulff and Berlin Mayor Klaus Wowereit at the Bernauer Straße memorial park to remember lives and liberty. Speeches extolled freedom and a minute of silence at noon honored those who died trying to flee to the West. "It is our shared responsibility to keep the memory alive and to pass it on to the coming generations as a reminder to stand up for freedom and democracy to ensure that such injustice may never happen again." entreated Mayor Wowereit. "It has been shown once again: Freedom is invincible at the end. No wall can permanently withstand the desire for freedom", proclaimed President Wulff.

Evidence-based practice

From Wikipedia, the free encyclopedia
 
Evidence-based practice (EBP) is the idea that occupational practices ought to be based on scientific evidence. That at first sight may seem to be obviously desirable, but the proposal has been controversial. Evidence-based practices have been gaining ground since the formal introduction of evidence-based medicine in 1992 and have spread to the allied health professions, education, management, law, public policy, architecture, and other fields. In light of studies showing problems in scientific research (such as the replication crisis), there is also a movement to apply evidence-based practices in scientific research itself. Research into the evidence-based practice of science is called metascience.

The movement towards evidence-based practices attempts to encourage and, in some instances, to force professionals and other decision-makers to pay more attention to evidence to inform their decision-making. The goal of evidence-based practice is to eliminate unsound or outdated practices in favor of more-effective ones by shifting the basis for decision making from tradition, intuition, and unsystematic experience to firmly grounded scientific research.

History

For most of history, professions have based their practices on expertise derived from experience passed down in the form of tradition. Many of these practices have not been justified by evidence, which has sometimes enabled quackery and poor performance. Even when overt quackery is not present, quality and efficiency of tradition-based practices may not be optimal. As the scientific method has become increasingly recognized as a sound means to evaluate practices, evidence-based practices have become increasingly adopted.

One of the earliest proponents of EBP was Archie Cochrane, an epidemiologist who authored the book Effectiveness and Efficiency: Random Reflections on Health Services in 1972. Cochrane's book argued for the importance of properly testing health care strategies, and was foundational to the evidence-based practice of medicine. Cochrane suggested that because resources would always be limited, they should be used to provide forms of health care which had been shown in properly designed evaluations to be effective. Cochrane maintained that the most reliable evidence was that which came from randomised controlled trials.

The term "evidence-based medicine" was introduced by Gordon Guyatt in 1990 in an unpublished program description, and the term was later first published in 1992. This marked the first evidence-based practice to be formally established. Some early experiments in evidence-based medicine involved testing primitive medical techniques such as bloodletting, and studying the effectiveness of modern and accepted treatments. There has been a push for evidence-based practices in medicine by insurance providers, which have sometimes refused coverage of practices lacking in systematic evidence of usefulness. It is now expected by most clients that medical professionals should make decisions based on evidence, and stay informed about the most up-to-date information. Since the widespread adoption of evidence-based practices in medicine, the use of evidence-based practices has rapidly spread to other fields.

More recently, there has been a push for evidence-based education. The use of evidence-based learning techniques such as spaced repetition can improve students' rate of learning. Some commentators have suggested that the lack of any substantial progress in the field of education is attributable to practice resting in the unconnected and noncumulative experience of thousands of individual teachers, each re-inventing the wheel and failing to learn from hard scientific evidence about 'what works'. Opponents of this view argue that it is hard to assess teaching methods because it depends on a host of factors, not least those to do with the style, personality and beliefs of the teacher and the needs of the particular children. Others argue the teacher experience could be combined with research evidence, but without the latter being treated as a privileged source. This is inline with a school of thought suggesting that EBP has limitations and a better alternative is to use Evidence-informed Practice (EIP). This process includes quantitative evidence, does not include non-scientific prejudices, but includes qualitative factors such as clinical experience and the discernment of practitioners and clients.

Versus tradition

Evidence-based practice is a philosophical approach that is in opposition to tradition. Some degree of reliance on "the way it was always done" can be found in almost every profession, even when those practices are contradicted by new and better information.

Some critics argue that since research is conducted on a population level, results may not generalise to each individual within the population. Therefore, evidence-based practices may fail to provide the best solution to each individual, and traditional practices may better accommodate individual differences. In response, researchers have made an effort to test whether particular practices work better for different subcultures, personality types etc. Some authors have redefined EBP to include practice that incorporates common wisdom, tradition, and personal values alongside practices based on evidence.

Evaluating evidence

Evaluating scientific research is extremely complex. The process can by greatly simplified with the use of a heuristic that ranks the relative strengths of results obtained from scientific research called a hierarchy of evidence. The design of the study and the endpoints measured (such as survival or quality of life) affect the strength of the evidence. Typically, systematic reviews and meta-analysis rank at the top of the hierarchy while randomized controlled trials rank above observational studies, and expert opinion and case reports rank at the bottom. There is broad agreement on the relative strength of the different types of studies, but there is no single, universally-accepted hierarchy of evidence. More than 80 different hierarchies have been proposed for assessing medical evidence.

Applications

Medicine

Evidence-based medicine (EBM) is an approach to medical practice intended to optimize decision-making by emphasizing the use of evidence from well-designed and well-conducted research. Although all medicine based on science has some degree of empirical support, EBM goes further, classifying evidence by its epistemologic strength and requiring that only the strongest types (coming from meta-analyses, systematic reviews, and randomized controlled trials) can yield strong recommendations; weaker types (such as from case-control studies) can yield only weak recommendations. The term was originally used to describe an approach to teaching the practice of medicine and improving decisions by individual physicians about individual patients. Use of the term rapidly expanded to include a previously described approach that emphasized the use of evidence in the design of guidelines and policies that apply to groups of patients and populations ("evidence-based practice policies").

Whether applied to medical education, decisions about individuals, guidelines and policies applied to populations, or administration of health services in general, evidence-based medicine advocates that to the greatest extent possible, decisions and policies should be based on evidence, not just the beliefs of practitioners, experts, or administrators. It thus tries to assure that a clinician's opinion, which may be limited by knowledge gaps or biases, is supplemented with all available knowledge from the scientific literature so that best practice can be determined and applied. It promotes the use of formal, explicit methods to analyze evidence and makes it available to decision makers. It promotes programs to teach the methods to medical students, practitioners, and policymakers.

A process has been specified that provides a standardised route for those seeking to produce evidence of the effectiveness of interventions. Originally developed to establish processes for the production of evidence in the housing sector, the standard is general in nature and is applicable across a variety of practice areas and potential outcomes of interest.

Mental health

To improve dissemination of evidence-based practices, the Association for Behavioral and Cognitive Therapies (ABCT) and the Society of Clinical Child and Adolescent Psychology (SCCAP, Division 53 of the American Psychological Association) maintain updated information on their websites on evidence-based practices in psychology for practitioners and the general public. An evidence-based practice consensus statement was developed at a summit on mental healthcare in 2018. As of June 23, 2019, this statement has been endorsed by 36 organizations.

Metascience

There has since been a movement for the use of evidence-based practice in conducting scientific research in attempt to address the replication crisis and other major issues affecting scientific research. The application of evidence-based practices to research itself is called metascience, which seeks to increase the quality of scientific research while reducing waste. It is also known as "research on research" and "the science of science", as it uses research methods to study how research is done and where improvements can be made. The five main areas of research in metascience are methodology, reporting, reproducibility, evaluation, and incentives. Metascience has produced a number of reforms in science such as the use of study pre-registration and the implementation of reporting guidelines with the goal of bettering scientific research practices.

Education

Evidence-based education (EBE), also known as evidence-based interventions, is a model in which policy-makers and educators use empirical evidence to make informed decisions about education interventions (policies, practices, and programs). In other words, decisions are based on scientific evidence rather than opinion.

EBE has gained attention since English author David H. Hargreaves suggested in 1996 that education would be more effective if teaching, like medicine, was a "research-based profession".

Since 2000, studies in Australia, England, Scotland and the USA have supported the use of research to improve educational practices in teaching reading.

In 1997, the National Institute of Child Health and Human Development (NICHD) convened a national panel to assess the effectiveness of different approaches used to teach children to read. The resulting National Reading Panel examined quantitative research studies on many areas of reading instruction, including phonics and whole language. In 2000 it published a report entitled Teaching Children to Read: An Evidence-based Assessment of the Scientific Research Literature on Reading and its Implications for Reading Instruction that provided a comprehensive review of what was known about best practices in reading instruction in the U.S.

This occurred around the same time as such international studies as the Programme for International Student Assessment (PISA) in 2000 and the Progress in International Reading Literacy Study (PIRLS) in 2001.

Subsequently, evidence-based practice (EBP) in education (also known as Scientifically based research), came into prominence in the U.S.A. under the No child left behind act of 2001, replace in 2015 by the Every Student Succeeds Act (ESSA).

In 2002 the U.S. Department of Education founded the Institute of Education Sciences (IES) to provide scientific evidence to guide education practice and policy .

English author Ben Goldacre advocated in 2013 for systemic change and more randomized controlled trials to assess the effects of educational interventions. In 2014 the National Foundation for Educational Research, Berkshire, England published a report entitled Using Evidence in the Classroom: What Works and Why. In 2014 the British Educational Research Association (BERA) and the Royal Society of Arts (RSA) advocated for a closer working partnership between teacher-researchers and the wider academic research community.

Reviews of existing research on education

The following websites offer free analysis and information on education research:

  • The Best Evidence Encyclopedia (BEE) is a free website created by the Johns Hopkins University School of Education's Center for Data-Driven Reform in Education (established in 2004) and is funded by the Institute of Education Sciences, U.S. Department of Education. It gives educators and researchers reviews about the strength of the evidence supporting a variety of English programs available for students in grades K–12. The reviews cover programs in areas such as Mathematics, Reading, Writing, Science, Comprehensive school reform, and Early childhood Education; and includes such topics as effectiveness of technology and struggling readers.
  • The Education Endowment Foundation was established in 2011 by The Sutton Trust, as a lead charity in partnership with Impetus Trust, together being the government-designated What Works Centre for UK Education.
  • Evidence for ESSA began in 2017 and is produced by the Center for Research and Reform in Education (CRRE) at Johns Hopkins University School of Education. It offers free up-to-date information on current PK-12 programs in reading, writing, math, science, and others that meet the standards of the Every Student Succeeds Act (ESSA) (the United States K–12 public education policy signed by President Obama in 2015). It also provides information on programs that do meet ESSA standards as well as those that do not.
  • What Works Clearinghouse (WWC), established in 2002, evaluates numerous educational programs, in twelve categories, by the quality and quantity of the evidence, and the effectiveness. It is operated by the federal National Center for Education Evaluation, and Regional Assistance (NCEE), part of Institute of Education Sciences (IES)
  • Social programs that work is administered by the Arnold Ventures LLC's Evidence-Based Policy team. The team is composed of the former leadership of the Coalition for Evidence-Based Policy, a nonprofit, nonpartisan organization advocating the use of well-conducted randomized controlled trials (RCTs) in policy decisions. It offers information on twelve types of social programs including education.

A variety of other organizations offer information on research and education.

Nature conservation is the moral philosophy and conservation movement focused on protecting species from extinction, maintaining and restoring habitats, enhancing ecosystem services, and protecting biological diversity. A range of values underlie conservation, which can be guided by biocentrism, anthropocentrism, ecocentrism, and sentientism, environmental ideologies that inform ecocultural practices and identities. There has recently been a movement towards evidence-based conservation which calls for greater use of scientific evidence to improve the effectiveness of conservation efforts. As of 2018 15% of land and 7.3% of the oceans were protected. Many environmentalists set a target of protecting 30% of land and marine territory by 2030.

Introduction

Conservation goals include conserving habitat, preventing deforestation, halting species extinction, reducing overfishing, and mitigating climate change. Different philosophical outlooks guide conservationists towards these different goals.

The principal value underlying many expressions of the conservation ethic is that the natural world has intrinsic and intangible worth along with utilitarian value – a view carried forward by parts of the scientific conservation movement and some of the older Romantic schools of the ecology movement. Philosophers have attached intrinsic value to different aspects of nature, whether this is individual organisms (biocentrism) or ecological wholes such as species or ecosystems (ecoholism).

More utilitarian schools of conservation have an anthropocentric outlook and seek a proper valuation of local and global impacts of human activity upon nature in their effect upon human wellbeing, now and to posterity. How such values are assessed and exchanged among people determines the social, political and personal restraints and imperatives by which conservation is practiced. This is a view common in the modern environmental movement. There is increasing interest in extending the responsibility for human wellbeing to include the welfare of sentient animals. Branches of conservation ethics focusing on sentient individuals include ecofeminism and compassionate conservation.

In the United States of America, the year 1864 saw the publication of two books which laid the foundation for Romantic and Utilitarian conservation traditions in America. The posthumous publication of Henry David Thoreau's Walden established the grandeur of unspoiled nature as a citadel to nourish the spirit of man. A very different book from George Perkins Marsh, Man and Nature, later subtitled "The Earth as Modified by Human Action", catalogued his observations of man exhausting and altering the land from which his sustenance derives.

The consumer conservation ethic is sometimes expressed by the four R's: " Rethink, Reduce, Recycle, Repair". This social ethic primarily relates to local purchasing, moral purchasing, the sustained, and efficient use of renewable resources, the moderation of destructive use of finite resources, and the prevention of harm to common resources such as air and water quality, the natural functions of a living earth, and cultural values in a built environment.

The person credited with formulating the conservation ethic in the United States is former president, Theodore Roosevelt.

Terminology

The conservation of natural resources is the fundamental problem. Unless we solve that problem, it will avail us little to solve all others.

Theodore Roosevelt

In common usage, the term refers to the activity of systematically protecting natural resources such as forests, including biological diversity. Carl F. Jordan defines the term as:

biological conservation as being a philosophy of managing the environment in a manner that does not despoil, exhaust or extinguish.

While this usage is not new, the idea of biological conservation has been applied to the principles of ecology, biogeography, anthropology, economy, and sociology to maintain biodiversity.

The term "conservation" itself may cover the concepts such as cultural diversity, genetic diversity, and the concept of movements environmental conservation, seedbank (preservation of seeds). These are often summarized as the priority to respect diversity.

Much recent movement in conservation can be considered a resistance to commercialism and globalization. Slow Food is a consequence of rejecting these as moral priorities, and embracing a slower and more locally focused lifestyle.

Practice

Distinct trends exist regarding conservation development. The need for conserving land has only recently intensified during what some scholars refer to as the Capitalocene epoch. This era marks the beginning of colonialism, globalization, and the industrial revolution that has led to global land change as well as climate change.

While many countries' efforts to preserve species and their habitats have been government-led, those in the North Western Europe tended to arise out of the middle-class and aristocratic interest in natural history, expressed at the level of the individual and the national, regional or local learned society. Thus countries like Britain, the Netherlands, Germany, etc. had what would be called non-governmental organizations – in the shape of the Royal Society for the Protection of Birds, National Trust and County Naturalists' Trusts (dating back to 1889, 1895, and 1912 respectively) Natuurmonumenten, Provincial Conservation Trusts for each Dutch province, Vogelbescherming, etc. – a long time before there were national parks and national nature reserves. This in part reflects the absence of wilderness areas in heavily cultivated Europe, as well as a longstanding interest in laissez-faire government in some countries, like the UK, leaving it as no coincidence that John Muir, the Scottish-born founder of the National Park movement (and hence of government-sponsored conservation) did his sterling work in the US, where he was the motor force behind the establishment of such national parks as Yosemite and Yellowstone. Nowadays, officially more than 10 percent of the world is legally protected in some way or the other, and in practice, private fundraising is insufficient to pay for the effective management of so much land with protective status.

Protected areas in developing countries, where probably as many as 70–80 percent of the species of the world live, still enjoy very little effective management and protection. Some countries, such as Mexico, have non-profit civil organizations and landowners dedicated to protecting vast private property, such is the case of Hacienda Chichen's Maya Jungle Reserve and Bird Refuge in Chichen Itza, Yucatán. The Adopt A Ranger Foundation has calculated that worldwide about 140,000 rangers are needed for the protected areas in developing and transition countries. There are no data on how many rangers are employed at the moment, but probably less than half the protected areas in developing and transition countries have any rangers at all and those that have them are at least 50% short This means that there would be a worldwide ranger deficit of 105,000 rangers in the developing and transition countries.

Adopt A Ranger fears that the ranger deficit is the greatest single limiting factor in effectively conserving nature in 75% of the world. Currently, no conservation organization or western country or international organization addresses this problem. Adopt A Ranger has been incorporated to draw worldwide public attention to the most urgent problem that conservation is facing in developing and transition countries: protected areas without field staff. Very specifically, it will contribute to solving the problem by fundraising to finance rangers in the field. It will also help governments in developing and transition countries to assess realistic staffing needs and staffing strategies.

Others, including Survival International, have advocated instead for cooperation with local tribal peoples, who are natural allies of the conservation movement and can provide cost-effective protection.

The terms conservation and preservation are frequently conflated outside the academic, scientific, and professional kinds of literature. The US National Park Service offers the following explanation of the important ways in which these two terms represent very different conceptions of environmental protection ethics:

″Conservation and preservation are closely linked and may indeed seem to mean the same thing. Both terms involve a degree of protection, but how that protection is carried out is the key difference. Conservation is generally associated with the protection of natural resources, while preservation is associated with the protection of buildings, objects, and landscapes. Put simply, conservation seeks the proper use of nature, while preservation seeks protection of nature from use.

During the environmental movement of the early 20th century, two opposing factions emerged: conservationists and preservationists. Conservationists sought to regulate human use while preservationists sought to eliminate human impact altogether.″

C.A. Claus presents a distinction for conservation practices. Claus divides conservation into conservation-far and conservation-near. Conservation-far is the means of protecting nature by separating it and safeguarding it from humans. Means of doing this include the creation of preserves or national parks. They're meat to keep the flora and fauna away from human influence and have become a staple method in the west. Conservation-near however is conservation via connection. The method of reconnecting people to nature through traditions and beliefs in order to foster a desire to protect nature. The basis is that instead of forcing compliance to separate from nature onto the people, instead conservationists work with locals and their traditions to find conservation efforts that work for all.

Evidence-based conservation

Evidence-based conservation is the application of evidence in conservation management actions and policy making. It is defined as systematically assessing scientific information from published, peer-reviewed publications and texts, practitioners' experiences, independent expert assessment, and local and indigenous knowledge on a specific conservation topic. This includes assessing the current effectiveness of different management interventions, threats and emerging problems, and economic factors.

Evidence-based conservation was organized based on the observations that decision making in conservation was based on intuition and/or practitioner experience often disregarding other forms of evidence of successes and failures (e.g. scientific information). This has led to costly and poor outcomes. Evidence-based conservation provides access to information that will support decision making through an evidence-based framework of “what works” in conservation.

The evidence-based approach to conservation is based on evidence-based practice which started in medicine and later spread to nursing, education, psychology, and other fields. It is part of the larger movement towards evidence-based practices.
