The European Space Agency is an intergovernmental organisation of 22 member states dedicated to the exploration of space. Established in 1975 and headquartered in Paris, ESA has a worldwide staff of about 2,200 in 2018 and an annual budget of about €6.68 billion (~US$7.43 billion) in 2020.

ESA's space flight programme includes human spaceflight (mainly through participation in the International Space Station programme); the launch and operation of uncrewed exploration missions to other planets and the Moon; Earth observation, science and telecommunication; designing launch vehicles; and maintaining a major spaceport, the Guiana Space Centre at Kourou, French Guiana. The main European launch vehicle Ariane 5 is operated through Arianespace with ESA sharing in the costs of launching and further developing this launch vehicle. The agency is also working with NASA to manufacture the Orion Spacecraft service module that will fly on the Space Launch System.

The agency's facilities are distributed among the following centres:
The European Space Agency Science Programme is a long-term programme of space science and space exploration missions.

History

Foundation

ESTEC buildings in Noordwijk, Netherlands. ESTEC was the main technical centre of ESRO and remains so for the successor organisation (ESA).
 
After World War II, many European scientists left Western Europe in order to work with the United States. Although the 1950s boom made it possible for Western European countries to invest in research and specifically in space-related activities, Western European scientists realised solely national projects would not be able to compete with the two main superpowers. In 1958, only months after the Sputnik shock, Edoardo Amaldi (Italy) and Pierre Auger (France), two prominent members of the Western European scientific community, met to discuss the foundation of a common Western European space agency. The meeting was attended by scientific representatives from eight countries, including Harrie Massey (United Kingdom).

The Western European nations decided to have two agencies: one concerned with developing a launch system, ELDO (European Launch Development Organization), and the other the precursor of the European Space Agency, ESRO (European Space Research Organisation). The latter was established on 20 March 1964 by an agreement signed on 14 June 1962. From 1968 to 1972, ESRO launched seven research satellites.

ESA in its current form was founded with the ESA Convention in 1975, when ESRO was merged with ELDO. ESA had ten founding member states: Belgium, Denmark, France, West Germany, Italy, the Netherlands, Spain, Sweden, Switzerland, and the United Kingdom. These signed the ESA Convention in 1975 and deposited the instruments of ratification by 1980, when the convention came into force. During this interval the agency functioned in a de facto fashion. ESA launched its first major scientific mission in 1975, Cos-B, a space probe monitoring gamma-ray emissions in the universe, which was first worked on by ESRO.

Later activities

Mock-up of the Ariane 1

ESA collaborated with NASA on the International Ultraviolet Explorer (IUE), the world's first high-orbit telescope, which was launched in 1978 and operated successfully for 18 years. A number of successful Earth-orbit projects followed, and in 1986 ESA began Giotto, its first deep-space mission, to study the comets Halley and Grigg–Skjellerup. Hipparcos, a star-mapping mission, was launched in 1989 and in the 1990s SOHO, Ulysses and the Hubble Space Telescope were all jointly carried out with NASA. Later scientific missions in cooperation with NASA include the Cassini–Huygens space probe, to which ESA contributed by building the Titan landing module Huygens.

As the successor of ELDO, ESA has also constructed rockets for scientific and commercial payloads. Ariane 1, launched in 1979, carried mostly commercial payloads into orbit from 1984 onward. The next two versions of the Ariane rocket were intermediate stages in the development of a more advanced launch system, the Ariane 4, which operated between 1988 and 2003 and established ESA as the world leader in commercial space launches in the 1990s. Although the succeeding Ariane 5 experienced a failure on its first flight, it has since firmly established itself within the heavily competitive commercial space launch market with 82 successful launches until 2018. The successor launch vehicle of Ariane 5, the Ariane 6, is under development and is envisioned to enter service in the 2020s.

The beginning of the new millennium saw ESA become, along with agencies like NASA, JAXA, ISRO, the CSA and Roscosmos, one of the major participants in scientific space research. Although ESA had relied on co-operation with NASA in previous decades, especially the 1990s, changed circumstances (such as tough legal restrictions on information sharing by the United States military) led to decisions to rely more on itself and on co-operation with Russia. A 2011 press issue thus stated:
Russia is ESA's first partner in its efforts to ensure long-term access to space. There is a framework agreement between ESA and the government of the Russian Federation on cooperation and partnership in the exploration and use of outer space for peaceful purposes, and cooperation is already underway in two different areas of launcher activity that will bring benefits to both partners.
Notable ESA programs include SMART-1, a probe testing cutting-edge space propulsion technology, the Mars Express and Venus Express missions, as well as the development of the Ariane 5 rocket and its role in the ISS partnership. ESA maintains its scientific and research projects mainly for astronomy-space missions such as Corot, launched on 27 December 2006, a milestone in the search for exoplanets.

On 21 January 2019, ArianeGroup and Arianespace announced a one-year contract with ESA to study and prepare for a mission to mine the Moon for lunar regolith.

Mission

The treaty establishing the European Space Agency reads:
ESA's purpose shall be to provide for, and to promote, for exclusively peaceful purposes, cooperation among the European States in space research and technology and their space applications, with a view to their being used for scientific purposes and for operational space applications systems
ESA is responsible for setting a unified space and related industrial policy, recommending space objectives to the member states, and integrating national programs like satellite development, into the European program as much as possible.

Jean-Jacques Dordain – ESA's Director General (2003–2015) – outlined the European Space Agency's mission in a 2003 interview:
Today space activities have pursued the benefit of citizens, and citizens are asking for a better quality of life on Earth. They want greater security and economic wealth, but they also want to pursue their dreams, to increase their knowledge, and they want younger people to be attracted to the pursuit of science and technology. I think that space can do all of this: it can produce a higher quality of life, better security, more economic wealth, and also fulfill our citizens' dreams and thirst for knowledge, and attract the young generation. This is the reason space exploration is an integral part of overall space activities. It has always been so, and it will be even more important in the future.

Non-full member states

Slovenia

Currently the only associated member state is Slovenia. Previously associated members were Austria, Norway and Finland, all of which later joined ESA as full members.

Canada

Since 1 January 1979, Canada has had the special status of a Cooperating State within ESA. By virtue of this accord, the Canadian Space Agency takes part in ESA's deliberative bodies and decision-making and also in ESA's programmes and activities. Canadian firms can bid for and receive contracts to work on programmes. The accord has a provision ensuring a fair industrial return to Canada. The most recent Cooperation Agreement was signed on 15 December 2010 with a term extending to 2020. For 2014, Canada's annual assessed contribution to the ESA general budget was €6,059,449 (CAD$8,559,050). For 2017, Canada has increased its annual contribution to €21,600,000 (CAD$30,000,000).

Budget appropriation and allocation

European Space Agency 2016 budget by domain out of a total budget is 5250M€.

ESA is funded from annual contributions by national governments as well as from an annual contribution by the European Union (EU).

The budget of ESA was €5.250 billion in 2016. Every 3–4 years, ESA member states agree on a budget plan for several years at an ESA member states conference. This plan can be amended in future years, however provides the major guideline for ESA for several years. The 2016 budget allocations for major areas of ESA activity are shown in the chart on the right.

Countries typically have their own space programmes that differ in how they operate organisationally and financially with ESA. For example, the French space agency CNES has a total budget of €2015 million, of which €755 million is paid as direct financial contribution to ESA. Several space-related projects are joint projects between national space agencies and ESA (e.g. COROT). Also, ESA is not the only European governmental space organisation (for example European Union Satellite Centre).

Enlargement

After the decision of the ESA Council of 21/22 March 2001, the procedure for accession of the European states was detailed as described the document titled "The Plan for European Co-operating States (PECS)". Nations that want to become a full member of ESA do so in 3 stages. First a Cooperation Agreement is signed between the country and ESA. In this stage, the country has very limited financial responsibilities. If a country wants to co-operate more fully with ESA, it signs a European Cooperating State (ECS) Agreement. The ECS Agreement makes companies based in the country eligible for participation in ESA procurements. The country can also participate in all ESA programmes, except for the Basic Technology Research Programme. While the financial contribution of the country concerned increases, it is still much lower than that of a full member state. The agreement is normally followed by a Plan For European Cooperating State (or PECS Charter). This is a 5-year programme of basic research and development activities aimed at improving the nation's space industry capacity. At the end of the 5-year period, the country can either begin negotiations to become a full member state or an associated state or sign a new PECS Charter. Many countries, most of which joined the EU in both 2004 and 2007, have started to co-operate with ESA on various levels.

During the Ministerial Meeting in December 2014, ESA ministers approved a resolution calling for discussions to begin with Israel, Australia and South Africa on future association agreements. The ministers noted that "concrete cooperation is at an advanced stage" with these nations and that "prospects for mutual benefits are existing".

A separate space exploration strategy resolution calls for further co-operation with the United States, Russia and China on "LEO exploration, including a continuation of ISS cooperation and the development of a robust plan for the coordinated use of space transportation vehicles and systems for exploration purposes, participation in robotic missions for the exploration of the Moon, the robotic exploration of Mars, leading to a broad Mars Sample Return mission in which Europe should be involved as a full partner, and human missions beyond LEO in the longer term."

EU and the European Space Agency

The political perspective of the European Union (EU) was to make ESA an agency of the EU by 2014, although this date was not met. The EU is already the largest single donor to ESA's budget and non-ESA EU states are observers at ESA.

Launch vehicle fleet

ESA has a fleet of different launch vehicles in service with which it competes in all sectors of the launch market. ESA's fleet consists of three major rocket designs: Ariane 5, Soyuz-2 and Vega. Rocket launches are carried out by Arianespace, which has 23 shareholders representing the industry that manufactures the Ariane 5 as well as CNES, at ESA's Guiana Space Centre. Because many communication satellites have equatorial orbits, launches from French Guiana are able to take larger payloads into space than from spaceports at higher latitudes. In addition, equatorial launches give spacecraft an extra 'push' of nearly 500 m/s due to the higher rotational velocity of the Earth at the equator compared to near the Earth's poles where rotational velocity approaches zero.

Ariane 5

Ariane 5 ECA transported to the ELA-3 launch pad

The Ariane 5 rocket is ESA's primary launcher. It has been in service since 1997 and replaced Ariane 4. Two different variants are currently in use. The heaviest and most used version, the Ariane 5 ECA, delivers two communications satellites of up to 10 tonnes into GTO. It failed during its first test flight in 2002, but has since made 82 consecutive successful flights until a partial failure in January 2018. The other version, Ariane 5 ES, was used to launch the Automated Transfer Vehicle (ATV) to the International Space Station (ISS) and will be used to launch four Galileo navigational satellites at a time.

In November 2012, ESA agreed to build an upgraded variant called Ariane 5 ME (Mid-life Evolution) which would increase payload capacity to 11.5 tonnes to GTO and feature a restartable second stage to allow more complex missions. Ariane 5 ME was scheduled to fly in 2018, but the whole project was scrapped in favor of Ariane 6, planned to replace Ariane 5 in the 2020s.

ESA's Ariane 1, 2, 3 and 4 launchers (the last of which was ESA's long-time workhorse) have been retired.

Soyuz

Soyuz Launch Complex

Soyuz-2 (also called the Soyuz-ST or Soyuz-STK) is a Russian medium payload launcher (ca. 3 metric tons to GTO) which was brought into ESA service in October 2011. ESA entered into a €340 million joint venture with the Russian Federal Space Agency over the use of the Soyuz launcher. Under the agreement, the Russian agency manufactures Soyuz rocket parts for ESA, which are then shipped to French Guiana for assembly.

ESA benefits because it gains a medium payload launcher, complementing its fleet while saving on development costs. In addition, the Soyuz rocket—which has been the Russian's space launch workhorse for more than 50 years—is proven technology with a very good safety record. Russia benefits in that it gets access to the Kourou launch site. Due to its proximity to the equator, launching from Kourou rather than Baikonur nearly doubles Soyuz's payload to GTO (3.0 tonnes vs. 1.7 tonnes).

Soyuz first launched from Kourou on 21 October 2011, and successfully placed two Galileo satellites into orbit 23,222 kilometres above Earth.

Vega

Vega rocket

Vega is ESA's carrier for small satellites. Developed by seven ESA members led by Italy, it is capable of carrying a payload with a mass of between 300 and 1500 kg to an altitude of 700 km, for low polar orbit. Its maiden launch from Kourou was on 13 February 2012. Vega began full commercial exploitation in December 2015.

The rocket has three solid propulsion stages and a liquid propulsion upper stage (the AVUM) for accurate orbital insertion and the ability to place multiple payloads into different orbits.

Ariane launch vehicle development funding

Historically, the Ariane family rockets have been funded primarily "with money contributed by ESA governments seeking to participate in the program rather than through competitive industry bids. This [has meant that] governments commit multiyear funding to the development with the expectation of a roughly 90% return on investment in the form of industrial workshare." ESA is proposing changes to this scheme by moving to competitive bids for the development of the Ariane 6.

Human space flight

History

Ulf Merbold became the first ESA astronaut to fly into space.

At the time ESA was formed, its main goals did not encompass human space flight; rather it considered itself to be primarily a scientific research organisation for uncrewed space exploration in contrast to its American and Soviet counterparts. It is therefore not surprising that the first non-Soviet European in space was not an ESA astronaut on a European space craft; it was Czechoslovak Vladimír Remek who in 1978 became the first non-Soviet or American in space (the first man in space being Yuri Gagarin of the Soviet Union) – on a Soviet Soyuz spacecraft, followed by the Pole Mirosław Hermaszewski and East German Sigmund Jähn in the same year. This Soviet co-operation programme, known as Intercosmos, primarily involved the participation of Eastern bloc countries. In 1982, however, Jean-Loup Chrétien became the first non-Communist Bloc astronaut on a flight to the Soviet Salyut 7 space station.

Because Chrétien did not officially fly into space as an ESA astronaut, but rather as a member of the French CNES astronaut corps, the German Ulf Merbold is considered the first ESA astronaut to fly into space. He participated in the STS-9 Space Shuttle mission that included the first use of the European-built Spacelab in 1983. STS-9 marked the beginning of an extensive ESA/NASA joint partnership that included dozens of space flights of ESA astronauts in the following years. Some of these missions with Spacelab were fully funded and organizationally and scientifically controlled by ESA (such as two missions by Germany and one by Japan) with European astronauts as full crew members rather than guests on board. Beside paying for Spacelab flights and seats on the shuttles, ESA continued its human space flight co-operation with the Soviet Union and later Russia, including numerous visits to Mir.

During the latter half of the 1980s, European human space flights changed from being the exception to routine and therefore, in 1990, the European Astronaut Centre in Cologne, Germany was established. It selects and trains prospective astronauts and is responsible for the co-ordination with international partners, especially with regard to the International Space Station. As of 2006, the ESA astronaut corps officially included twelve members, including nationals from most large European countries except the United Kingdom.

In the summer of 2008, ESA started to recruit new astronauts so that final selection would be due in spring 2009. Almost 10,000 people registered as astronaut candidates before registration ended in June 2008. 8,413 fulfilled the initial application criteria. Of the applicants, 918 were chosen to take part in the first stage of psychological testing, which narrowed down the field to 192. After two-stage psychological tests and medical evaluation in early 2009, as well as formal interviews, six new members of the European Astronaut Corps were selected – five men and one woman.

Astronaut names

The astronauts of the European Space Agency are:
In the 1980s, France pressed for an independent European crew launch vehicle. Around 1978 it was decided to pursue a reusable spacecraft model and starting in November 1987 a project to create a mini-shuttle by the name of Hermes was introduced. The craft was comparable to early proposals for the Space Shuttle and consisted of a small reusable spaceship that would carry 3 to 5 astronauts and 3 to 4 metric tons of payload for scientific experiments. With a total maximum weight of 21 metric tons it would have been launched on the Ariane 5 rocket, which was being developed at that time. It was planned solely for use in low Earth orbit space flights. The planning and pre-development phase concluded in 1991; the production phase was never fully implemented because at that time the political landscape had changed significantly. With the fall of the Soviet Union ESA looked forward to co-operation with Russia to build a next-generation space vehicle. Thus the Hermes programme was cancelled in 1995 after about 3 billion dollars had been spent. The Columbus space station programme had a similar fate.

In the 21st century, ESA started new programmes in order to create its own crew vehicles, most notable among its various projects and proposals is Hopper, whose prototype by EADS, called Phoenix, has already been tested. While projects such as Hopper are neither concrete nor to be realised within the next decade, other possibilities for human spaceflight in co-operation with the Russian Space Agency have emerged. Following talks with the Russian Space Agency in 2004 and June 2005, a co-operation between ESA and the Russian Space Agency was announced to jointly work on the Russian-designed Kliper, a reusable spacecraft that would be available for space travel beyond LEO (e.g. the moon or even Mars). It was speculated that Europe would finance part of it. A €50 million participation study for Kliper, which was expected to be approved in December 2005, was finally not approved by the ESA member states. The Russian state tender for the project was subsequently cancelled in 2006.

In June 2006, ESA member states granted 15 million to the Crew Space Transportation System (CSTS) study, a two-year study to design a spacecraft capable of going beyond Low-Earth orbit based on the current Soyuz design. This project was pursued with Roskosmos instead of the cancelled Kliper proposal. A decision on the actual implementation and construction of the CSTS spacecraft was contemplated for 2008. In mid-2009 EADS Astrium was awarded a €21 million study into designing a crew vehicle based on the European ATV which is believed to now be the basis of the Advanced Crew Transportation System design.

In November 2012, ESA decided to join NASA's Orion programme. The ATV would form the basis of a propulsion unit for NASA's new crewed spacecraft. ESA may also seek to work with NASA on Orion's launch system as well in order to secure a seat on the spacecraft for its own astronauts.

In September 2014, ESA signed an agreement with Sierra Nevada Corporation for co-operation in Dream Chaser project. Further studies on the Dream Chaser for European Utilization or DC4EU project were funded, including the feasibility of launching a Europeanized Dream Chaser onboard Ariane 5.

Cooperation with other countries and organisations

ESA has signed co-operation agreements with the following states that currently neither plan to integrate as tightly with ESA institutions as Canada, nor envision future membership of ESA: Argentina, Brazil, China, India (for the Chandrayan mission), Russia and Turkey.

Additionally, ESA has joint projects with the European Union, NASA of the United States and is participating in the International Space Station together with the United States (NASA), Russia and Japan (JAXA).

European Union

  ESA and EU member states
  ESA-only members
  EU-only members

ESA is not an agency or body of the European Union (EU), and has non-EU countries (Norway, Switzerland, and the United Kingdom) as members. There are however ties between the two, with various agreements in place and being worked on, to define the legal status of ESA with regard to the EU.

There are common goals between ESA and the EU. ESA has an EU liaison office in Brussels. On certain projects, the EU and ESA co-operate, such as the upcoming Galileo satellite navigation system. Space policy has since December 2009 been an area for voting in the European Council. Under the European Space Policy of 2007, the EU, ESA and its Member States committed themselves to increasing co-ordination of their activities and programmes and to organising their respective roles relating to space.

The Lisbon Treaty of 2009 reinforces the case for space in Europe and strengthens the role of ESA as an R&D space agency. Article 189 of the Treaty gives the EU a mandate to elaborate a European space policy and take related measures, and provides that the EU should establish appropriate relations with ESA.

Former Italian astronaut Umberto Guidoni, during his tenure as a Member of the European Parliament from 2004 to 2009, stressed the importance of the European Union as a driving force for space exploration, "since other players are coming up such as India and China it is becoming ever more important that Europeans can have an independent access to space. We have to invest more into space research and technology in order to have an industry capable of competing with other international players."

The first EU-ESA International Conference on Human Space Exploration took place in Prague on 22 and 23 October 2009. A road map which would lead to a common vision and strategic planning in the area of space exploration was discussed. Ministers from all 29 EU and ESA members as well as members of parliament were in attendance.

National space organisations of member states

  • The Centre National d'Études Spatiales (CNES) (National Centre for Space Study) is the French government space agency (administratively, a "public establishment of industrial and commercial character"). Its headquarters are in central Paris. CNES is the main participant on the Ariane project. Indeed, CNES designed and tested all Ariane family rockets (mainly from its centre in Évry near Paris)
  • The UK Space Agency is a partnership of the UK government departments which are active in space. Through the UK Space Agency, the partners provide delegates to represent the UK on the various ESA governing bodies. Each partner funds its own programme.
  • The Italian Space Agency (Agenzia Spaziale Italiana or ASI) was founded in 1988 to promote, co-ordinate and conduct space activities in Italy. Operating under the Ministry of the Universities and of Scientific and Technological Research, the agency cooperates with numerous entities active in space technology and with the president of the Council of Ministers. Internationally, the ASI provides Italy's delegation to the Council of the European Space Agency and to its subordinate bodies.
  • The German Aerospace Center (DLR) (German: Deutsches Zentrum für Luft- und Raumfahrt e. V.) is the national research centre for aviation and space flight of the Federal Republic of Germany and of other member states in the Helmholtz Association. Its extensive research and development projects are included in national and international cooperative programmes. In addition to its research projects, the centre is the assigned space agency of Germany bestowing headquarters of German space flight activities and its associates.
  • The Instituto Nacional de Técnica Aeroespacial (INTA) (National Institute for Aerospace Technique) is a Public Research Organization specialised in aerospace research and technology development in Spain. Among other functions, it serves as a platform for space research and acts as a significant testing facility for the aeronautic and space sector in the country.

NASA

ESA has a long history of collaboration with NASA. Since ESA's astronaut corps was formed, the Space Shuttle has been the primary launch vehicle used by ESA's astronauts to get into space through partnership programmes with NASA. In the 1980s and 1990s, the Spacelab programme was an ESA-NASA joint research programme that had ESA develop and manufacture orbital labs for the Space Shuttle for several flights on which ESA participate with astronauts in experiments.

In robotic science mission and exploration missions, NASA has been ESA's main partner. Cassini–Huygens was a joint NASA-ESA mission, along with the Infrared Space Observatory, INTEGRAL, SOHO, and others. Also, the Hubble Space Telescope is a joint project of NASA and ESA. Future ESA-NASA joint projects include the James Webb Space Telescope and the proposed Laser Interferometer Space Antenna. NASA has committed to provide support to ESA's proposed MarcoPolo-R mission to return an asteroid sample to Earth for further analysis. NASA and ESA will also likely join together for a Mars Sample Return Mission.

Cooperation with other space agencies

Since China has started to invest more money into space activities, the Chinese Space Agency has sought international partnerships. ESA is, beside the Russian Space Agency, one of its most important partners. Two space agencies cooperated in the development of the Double Star Mission. In 2017, ESA sent two astronauts to China for two weeks sea survival training with Chinese astronauts in Yantai, Shandong.

ESA entered into a major joint venture with Russia in the form of the CSTS, the preparation of French Guiana spaceport for launches of Soyuz-2 rockets and other projects. With India, ESA agreed to send instruments into space aboard the ISRO's Chandrayaan-1 in 2008. ESA is also co-operating with Japan, the most notable current project in collaboration with JAXA is the BepiColombo mission to Mercury.

Speaking to reporters at an air show near Moscow in August 2011, ESA head Jean-Jacques Dordain said ESA and Russia's Roskosmos space agency would "carry out the first flight to Mars together."

ISS module Columbus at Kennedy Space Center's Space Station Processing Facility
 
With regard to the International Space Station (ISS) ESA is not represented by all of its member states: 10 of the 21 ESA member states currently participate in the project: Belgium, Denmark, France, Germany, Italy, Netherlands, Norway, Spain, Sweden and Switzerland. Austria, Finland and Ireland chose not to participate, because of lack of interest or concerns about the expense of the project. The United Kingdom withdrew from the preliminary agreement because of concerns about the expense of the project. Portugal, Luxembourg, Greece, the Czech Republic, Romania and Poland joined ESA after the agreement had been signed. ESA is taking part in the construction and operation of the ISS with contributions such as Columbus, a science laboratory module that was brought into orbit by NASA's STS-122 Space Shuttle mission and the Cupola observatory module that was completed in July 2005 by Alenia Spazio for ESA. The current estimates for the ISS are approaching €100 billion in total (development, construction and 10 years of maintaining the station) of which ESA has committed to paying €8 billion. About 90% of the costs of ESA's ISS share will be contributed by Germany (41%), France (28%) and Italy (20%). German ESA astronaut Thomas Reiter was the first long-term ISS crew member.

ESA has developed the Automated Transfer Vehicle for ISS resupply. Each ATV has a cargo capacity of 7,667 kilograms (16,903 lb). The first ATV, Jules Verne, was launched on 9 March 2008 and on 3 April 2008 successfully docked with the ISS. This manoeuvre, considered a major technical feat, involved using automated systems to allow the ATV to track the ISS, moving at 27,000 km/h, and attach itself with an accuracy of 2 cm.

As of 2013, the spacecraft establishing supply links to the ISS are the Russian Progress and Soyuz, European ATV, Japanese Kounotori (HTV), and the USA COTS program vehicles Dragon and Cygnus.

European Life and Physical Sciences research on board the International Space Station (ISS) is mainly based on the European Programme for Life and Physical Sciences in Space programme that was initiated in 2001.

ESA and the EU institutions

The Flag of Europe is the one to be flown in space during missions (for example it was flown by ESA's Andre Kuipers during Delta mission).

The Commission is increasingly working together towards common objectives. Some 20 per cent of the funds managed by ESA now originate from the supranational budget of the European Union. In recent years the ties between ESA and the European institutions have been reinforced by the increasing role that space plays in supporting Europe's social, political and economic policies.

The legal basis for the EU/ESA co-operation is provided by a Framework Agreement which entered into force in May 2004. According to this agreement, the European Commission and ESA co-ordinate their actions through the Joint Secretariat, a small team of EC's administrators and ESA executive. The Member States of the two organisations meet at ministerial level in the Space Council, which is a concomitant meeting of the EU and ESA Councils, prepared by Member States representatives in the High-level Space Policy Group (HSPG). 

ESA maintains a liaison office in Brussels to facilitate relations with the European institutions.

Guaranteeing European access to space

In May 2007, the 29 European countries expressed their support for the European Space Policy in a resolution of the Space Council, unifying the approach of ESA with those of the European Union and their member states.

Prepared jointly by the European Commission and ESA's Director General, the European Space Policy sets out a basic vision and strategy for the space sector and addresses issues such as security and defence, access to space and exploration.

Through this resolution, the EU, ESA and their Member States all commit to increasing co-ordination of their activities and programmes and their respective roles relating to space.

  • These nations are considered initial signatories, but since they were members of neither ESRO nor ELDO (the precursor organisations to ESA) the Convention could only enter into force when the last of the other 10 founders ratified it.

    African independence movements

    From Wikipedia, the free encyclopedia
     
    The African Independence Movements took place in the 20th century, when a wave of struggles for independence in European-ruled African territories were witnessed.

    Notable independence movements took place:

    British overseas territories

    British Kenya

    British-ruled Kenya was the place of a rebellion from 1952 to 1960, an insurgency by Kenyan rebels against the British colonialist rule. The core of the rebellion was formed by members of the Kikuyu ethnic group, along with smaller numbers of Embu and Meru.

    French overseas territories

    The flag of Algeria

    French Algeria

    The colonization of Algeria:
    French colonization of Algeria began on June 14, 1830 when French soldiers arrived in a coastal town, Sidi Ferruch. The troops did not encounter significant resistance, and within 3 weeks, the occupation was officially declared on July 5, 1830. After a year of occupation over 3,000 Europeans (mostly French) had arrived ready to start businesses and claim land. In reaction to the French occupation, Amir Abd Al-Qadir was elected leader of the resistance movement. On November 27, 1832, Abd Al-Qadir declared that he reluctantly accepted the position, but saw serving in the position as a necessity in order to protect the country from the enemy (the French). Abd Al-Qadir declared the war against the French as jihad, opposed to liberation. Abd Al-Qadir's movement was unique from other independence movements because the main call to action was for Islam rather than nationalism. Abd Al-Qadir fought the French for nearly two decades, but was defeated when the Tijaniyya Brotherhood agreed to submit to French rule as long as “they were allowed to exercise freely the rites of their religion, and the honor of their wives and daughters was respected”. In 1847 Abd Al-Qadir was defeated and there were other resistance movements but none of them were as large nor as effective in comparison. Due to the lack of effective large-scale organizing, Algerian Muslims “resorted to passive resistance or resignation, waiting for new opportunities,” which came about from international political changes due to World War I. As World War I became a reality, officials discussed drafting young Algerians into the army to fight for the French, but there was some opposition. European settlers were worried that if Algerians served in the army, then those same Algerians would want rewards for their service and claim political rights (Alghailani). Despite the opposition, the French government drafted young Algerians into the French army for World War I.

    Since many Algerians had fought as French soldiers during the First World War, just as the European settlers had suspected, Muslim Algerians wanted political rights after serving in the war. Muslim Algerians felt it was all the more unfair that their votes were not equal to the other Algerians (the settler population) especially after 1947 when the Algerian Assembly was created. This assembly was composed of 120 members. Muslim Algerians who represented about 9 million people could designate 50% of the Assembly members while 900,000 non-Muslim Algerians could designate the other half.

    Muslim mosque in Algeria

    Religion in Algeria:
    When the French arrived in Algeria in 1830, they quickly took control of all Muslim establishments. The French took the land in order to transfer wealth and power to the new French settlers. In addition to taking property relating Muslim establishments, the French also took individuals’ property and by 1851, they had taken over 350,000 hectares of Algerian land. For many Algerians, Islam was the only way to escape the control of French Imperialism. In the 1920s and 30s, there was an Islamic revival led by the ulama, and this movement became the basis for opposition to French rule in Algeria. Ultimately, French colonial policy failed because the ulama, especially Ibn Badis, utilized the Islamic institutions to spread their ideas of revolution. For example, Ibn Badis used the “networks of schools, mosques, cultural clubs, and other institutions,” to educate others, which ultimately made the revolution possible. Education became an even more effective tool for spreading their revolutionary ideals when Muslims became resistant to sending their children to French schools, especially their daughters. Ultimately, this led to conflict between the French and the Muslims because there were effectively two different societies within one country.
     
    Monument to those killed in the first independence protest

    Leading up to the fight for independence:
    The fight for independence, or the Algerian war, began with a massacre that occurred on May 8, 1945 in Setif, Algeria. After WWII ended, nationalists in Algeria, in alignment with the American anti-colonial sentiment, organized marches, but these marches became bloody massacres. An estimated 6,000-45,000 Algerians were killed by the French army. This event triggered a radicalization of Algerian nationalists and it was a crucial event in leading up to the Algerian War.

    In response to the massacre, Messali Hadj, the leader of the independence party, the Movement for the Triumph of Democratic Liberties (MTLD), "turned to electoral politics. With Hadj’s leadership, the party won multiple municipal offices. But, in the 1948 elections the candidates were arrested by Interior Minister Jules Moch. While the candidates were being arrested, the local authorities stuffed ballots for Muslim men, non-members of the independence party. Since the MTLD could not gain independence via elections, Hadj turned to violent means and consulted "the head of its parliamentary wing, Hocine A ̈ıt Ahmed, to advise on how the party might win Algeria’s independence through force of arms." A ̈ıt Ahmed had never been formally trained in strategy, so he studied former rebellions against the French and he came to the conclusion that "no other anti-colonial movement had had to deal with such a sizable and politically powerful settler population." Due to the powerful settler population, A ̈ıt Ahmed believed that Algeria could only achieve independence if the movement became relevant in the international political arena. Over the next few years, members of the MTLD began to disagree about which direction the organization should go to achieve independence, so eventually the more radical members broke off to form the National Liberation Front (FLN).

    The fight for independence in the international arena:
    The FLN officially started the Algerian War for Independence and followed A ̈ıt Ahmed's advice by creating tensions in the Franco-American relations. Due to the intensifying global relations, the Algerian War became a "kind of world war—a war for world opinion". In closed-door meetings the United States encouraged France to negotiate with the FLN, but during UN meetings the United States helped France end discussion on Algeria. Ultimately, the strategy of just focusing on superpowers was not successful for Algeria, but once A ̈ıt Ahmed began to exploit international rivalries the Algerian war for independence was successful.

    Algerian women in the Algerian War of Independence
     
    Women in the fight for independence:
    Thousands of women took part in the war, even on deadly missions. Women took part as “combatants, spies, fundraisers, and couriers, as well as nurses, launderers, and cooks”. 3% of all fighters were women, which is roughly equivalent to 11,000 women.

    This is a quote of three women who participated in the war: “We had visited the site and noted several possible targets. We had been told to place two bombs, but we were three, and at the last moment, since it was possible, we decided to plant three bombs. Samia and I carried three bombs from the Casbah to Bab el Oued, where they were primed...Each of us placed a bomb, and at the appointed time there were two explosions; one of the bombs was defective and didn’t go off.’ - Djamila B., Zohra D., and Samia, Algiers, September 1956”.

    Outcome of Independence:
    Algeria gained independence on February 20, 1962 when the French government signed a peace accord.

    While the women's movement made significant gains post-independence, peace in the country did not last long. Shortly after gaining independence, the Algerian Civil War began. The civil war erupted from anger regarding one party rule and ever increasing unemployment rates in Algeria. In October 1988, young Algerian men took to the streets and participated in week-long riots.

    In addition, the Algerian war for independence inspired liberationists in South Africa. However, the liberationists were unsuccessful in implementing Alergian strategy into their independence movement.

    The Algerian Independence movement also had a lasting impact on French thought about the relationship between the government and religion.

    Portuguese overseas territories

    Portugal built a five-century-long global empire. Portuguese overseas expansion began in the 15th century, thanks to several factors that gave the small coastal nation an advantage over its larger European neighbours. First, in the 14th century, Portuguese shipbuilders invented several new techniques that made sailing in the stormy Atlantic Ocean more practical. They combined elements of different types of ships to construct stronger, roomier and more manoeuvrable caravels. They also took advantage of more reliable compasses for navigation, and benefited from the school for navigation created by Prince Henry the Navigator (1394–1460) at Sagres in 1419. Starting with voyages to Madeira and the Azores (islands in the Atlantic) in the first part of the 14th century, the Portuguese systematically extended their explorations as far as Japan by the 16th century. In the process, they established forts and settlements along the West and East African coasts. In the 16th through 18th centuries, the Portuguese lost their lead to other European nations, notably England and France, but played a major role in the slave trade to satisfy the demand for labour in Brazil and other American markets. By the beginning of the 19th century, Portugal controlled outposts at six locations in Africa. One was the Cape Verde Islands, located about 700 miles due west of Dakar, Senegal. Claimed for Portugal by Diogo Gomes about 1458, this archipelago of eight major islands was devoted to sugar cultivation using slaves taken from the African mainland. The Portuguese once had extensive claims on the West African coast—since they were the first Europeans to explore it systematically—but by 1800 they were left with only a few ports at the mouth of the Rio Geba in what is now known as the Guinea-Bissau. To the east, the Portuguese controlled the islands of São Tomé and Príncipe, located south of the mouth of the Niger River. Like the Cape Verde Islands, they were converted to sugar production in the early 16th century using slaves acquired on the mainland in the vicinity of the Congo River. By the end of the 19th century, Portuguese landowners had successfully introduced cocoa production using forced African labour. Further south, the Portuguese claimed both sides of the mouth of the Congo River, as well as the Atlantic coast as far south as the Rio Cunene. In practical terms, Portugal controlled port cities like those of Cabinda (north of the Congo River mouth), Ambriz (south of the Congo's mouth), Luanda and Benguela (on the Angolan coast) plus some river towns in the Angolan interior.

    The last area claimed by Portugal in Africa was along the southeast coast on either side of the mouth of the Zambezi River. After reaching this area, known as the Swahili Coast, at the end of the 15th century, the Portuguese came to dominate most of it by the end of the 16th century. During the 17th century, they lost control of everything north of Cape Delgado to Arabs from Oman (who established the Sultanate of Zanzibar), leaving them with major ports at Mozambique, Quelimane, and Lourenço Marques, plus settlements along the Zambezi and other rivers.

    Despite these holdings, the Portuguese hold in Africa was problematic. The first cause was the small size of Portugal's population, coupled with the lack of popular support for overseas empire. Exploration and conquest began as an enterprise supported by the nobility, and Portuguese peasants rarely participated unless forced to do so. When the common people of Portugal did chose to emigrate, they were much more likely to head to Brazil and other territories than to Africa. To induce Europeans to move to its African holdings, the Portuguese government resorted to releasing degradados—convicted criminals—from prison in exchange for accepting what amounted to exile in Africa. Angola, in particular, gained a reputation as a Portuguese penal colony. Also, since the European population remained almost entirely male, the Portuguese birth rate was negligible, although plenty of "Afro-Lusitanians" were born to African mothers. As a result, the European population of Portugal's African settlements was never very large, and community leaders were just as likely to owe their loyalty to local African governments as they did to the distant Portuguese government.

    A second cause of weakness in Portuguese Africa was the effects of three centuries of Atlantic slave trade which had roots in the older African slave trade. Once the Atlantic triangular trade got underway, many Portuguese (including many Brazilian traders) in Africa found little incentive to engage in any other kind of profitable economic activity. The economies of Guinea, Angola and Mozambique became almost entirely devoted to the export of slaves to the New World (plus gold and ivory where they were available) while on the islands, slaves were used to grow sugar for export. Colonial authorities did nothing to stop the slave trade, which had sympathisers even among the several native African tribes, and many became wealthy by supporting it, while the traders themselves generated huge profits with which they secured allies in Africa and Portugal.

    Although anti-slavery efforts became organised in Europe in the 18th century, the slave trade only came to an end in the early 19th century, thanks in large part to English efforts to block shipping to the French during the Napoleonic Wars. Portugal was one of the first countries in the world to outlaw slavery, and did it so in mainland Portugal during the 18th century. The Portuguese government ended colonial slavery in stages with a final decree in 1858 that outlawed slavery in the overseas empire. The gradual pace of abolition was due to the strength of pro-slavery forces in Portuguese politics, Brazil and in Africa, they interfered with colonial administrators who challenged long-established and powerful commercial interests.

    The Napoleonic Wars added a new force to the Portuguese political scene—republicanism—introduced as an alternative to the monarchy by French troops in 1807. The French invasion induced the Portuguese royal family to make the controversial decision to flee to Brazil (on English ships), from where they ruled until 1821. By the time King João VI returned to Lisbon, he faced a nobility divided in their support for him personally, plus a middle class that wanted a constitutional monarchy. During Joao VI's reign (1821–1826) and that of his successors—Peter IV (1826–1831), Maria (1833–1853), Peter V (1853–1861), Louis I (1861–1889), and Carlos (1889–1908)—there was a civil war that lasted from 1826 to 1834, a long period characterised by what one author called "ministerial instability and chronic insurrection" from 1834 to 1853, and finally the end of the monarchy when both Carlos and his heir were assassinated on February 1, 1908. Under those circumstances, colonial officials appointed by governments in Lisbon were more concerned with politics at home than with administering their African territories.

    As it did everywhere else, the Industrial Revolution stimulated change in Portuguese Africa. It created a demand for tropical raw materials like vegetable oils, cotton, cocoa and rubber, and it also created a need for markets to purchase the expanded quantity of goods issuing from factories. In Portugal's case, most of the factories were located in England, which had had a special relationship with Portugal ever since Philippa, the daughter of England's John of Gaunt, married John of Avis, the founder of the Portuguese second dynasty. Prodded by Napoleon's invasion and English support for the royal family's escape to Brazil, King João and his successors eliminated tariffs, ended trade monopolies and generally opened the way for British merchants to become dominant in the Portuguese empire. At times, that caused friction, such as when both British and Portuguese explorers claimed the Shire Highlands (located in modern Malawi), but for the most part Great Britain supported the Portuguese position in exchange for incorporating Portugal's holdings into the British economic sphere.

    With neither a large European population nor African wage earners, the Portuguese colonies offered poor markets for manufactured goods from the private sector. Consequently, industrialisation arrived in the form of government programs designed to improve internal communications and increase the number of European settlers. During the late 1830s, the government headed by Marquis Sá da Bandeira tried to encourage Portuguese farmers to migrate to Angola, with little success. Between 1845 and 1900, the European population of Angola rose from 1,832 to only about 9,000. European migration to Mozambique showed slightly better results—about 11,000 in 1911—but many were British from South Africa rather than Portuguese. The other major force for change was the rivalries that developed between European nations in the century between the end of the Napoleonic Wars and the outbreak of World War I. Forbidden from fighting each other by the "balance of power" established by the Treaty of Vienna, they competed in other ways including scientific discoveries, athletic competitions, exploration and proxy wars. Although not a major power anymore, Portugal participated in the competition, especially by sending out explorers to solidify their claim to all of the land between Angola and Mozambique. That bought them into conflict with men like Cecil Rhodes, whose own vision of an empire from "Cape to Cairo" required that the British gain control over the same land.

    European rivalries appeared most often as commercial competition, and in 19th century Africa, that included the right to move goods by steamboat along rivers. The British had a head start thanks to their early adoption of steam technology and their supremacy on the high seas. They became the strongest proponents of the principle of "free trade" which prohibited countries from creating legal barriers to another country's merchants. Occasionally, Portuguese leaders resisted, but the British alliance provided sufficient benefits to convince various administrations to go along (although they faced revolts at home and in their colonies).

    It was Portugal's claim to the land on either side of the mouth of the Congo River that triggered the events leading up to the Congress of Berlin. That claim, which dated from Diogo Cão's voyage in 1484, gave Portugal places from which naval patrols could control access to Africa's largest river system. The British eyed this arrangement with suspicion for years, but paid tariffs (like everyone else) for the right to trade there, mostly for slaves.

    After the abolition of slavery got underway, the Portuguese dragged their heels, so in 1839 the British government declared its right to inspect Portuguese ships for evidence of slave trading with or without Portuguese consent. That stirred the Portuguese to action, and in a subsequent series of agreements made in the 1840s, the British acquired the right to land their ships to land where no Portuguese authorities were present. When the Portuguese refused to renew the agreement in 1853, the British ceased paying tariffs at the ports on either side of the Congo River mouth, claiming that Portugal's claim had expired because they had left the area unoccupied for too long. Portugal reoccupied the ports of Cabinda and Ambriz in 1855, and relations with Great Britain improved after that. The dispute set a precedent, however, that effective occupation was a prerequisite for recognition of colonial claims. The question continued to reappear until 1885 when it was enshrined in the agreements that emanated from the Congress of Berlin.

    The final straw was the Anglo-Portuguese Treaty signed on February 26, 1884. It granted exclusive navigation rights on the Congo River to Britain in exchange for British guarantees of Portugal's control of the coast at the mouth of the Congo River. Most significantly, it prevented the French from taking advantage of treaties signed by one of its explorers (Savorgnan de Brazza) with Africans living along the north side of the Congo River. International protests forced the two countries to abandon the treaty in June 1884, and Bismarck used the controversy to call the Congress of Berlin later that year.

    The Portuguese were the first Europeans to claim territory in sub-Saharan Africa, and their example inspired imitation from other European powers. For the British, the Portuguese were acceptable proxies in the competition with France, Russia and Germany for world domination. For Portuguese governments, the British alliance gave them influence that they could not command themselves, while the idea of a Portuguese empire offered something with which to distract domestic opponents from the struggles initiated by the Napoleonic Wars.

    The issues that were raised by Portugal's claims in Africa and the efforts of other countries to whittle them down became the fundamental issues of the Congress of Berlin. In the end, the Congress settled more than the future of Portugal's African holdings—it also set the rules for any European government which wished to establish an empire in Africa.

    In the 1950s, after World War II, several African territories became independent from their European rulers, but the oldest Europe-ruled territories, those ruled by Portugal, were rebranded "Overseas Provinces" from the former designation as Portuguese colonies. This was a firm effort of Portugal's authorities to preserve its old African possessions abroad and refuse any claims of independence. This was followed by a wave of strong economic and social developments in all Portuguese Africa, in particular the overseas provinces of Angola and Mozambique.

    By the 1960s, several organisations were founded to support independence's claims of the Portuguese overseas provinces in Africa. They were mostly entirely based and supported from outside Portugal's territories. Headquartered and managed in countries like Senegal, Tanzania, Algeria, Guinea and Ethiopia, these guerrilla movements sought weapons, financing and political support in Eastern Bloc's communist states and the People's Republic of China. A Cold War conflict in Portuguese Africa was about to start. Marxist-Leninist and Maoist ideologies, backed by countries like the Soviet Union and People's Republic of China were behind the nationalist guerrilla movements created to attack Portuguese possessions and claim independence. The USA and other countries, in order to counter communist growing influence in the region also started to support some nationalist guerrillas in their fight against Portugal. The series of guerrilla wars involving Portugal and several armed nationalist groups from Africa in its overseas provinces of Angola, Guinea, and Mozambique, become known as the Portuguese Colonial War (Guerra Colonial or Guerra do Ultramar).

    African nationalism in Portuguese Africa

    Portuguese Angola

    Portuguese soldiers in Angola.

    In Portuguese Angola, the rebellion of the ZSN was taken up by the União das Populações de Angola (UPA), which changed its name to the National Liberation Front of Angola (FNLA) in 1962. On February 4, 1961, the People's Movement for the Liberation of Angola (MPLA) took credit for the attack on the prison of Luanda, where seven policemen were killed. On March 15, 1961, the UPA, in a tribal attack, started the massacre of white populations and black workers born in other regions of Angola. This region would be retaken by large military operations that, however, would not stop the spread of the guerrilla actions to other regions of Angola, such as Cabinda, the east, the southeast and the central plateaus.

    Portuguese Guinea

    PAIGC's checkpoint in 1974

    In Portuguese Guinea, the Marxist African Party for the Independence of Guinea and Cape Verde (PAIGC) started fighting in January 1963. Its guerrilla fighters attacked the Portuguese headquarters in Tite, located to the south of Bissau, the capital, near the Corubal river . Similar actions quickly spread across the entire colony, requiring a strong response from the Portuguese forces.

    The war in Guinea placed face to face Amílcar Cabral, the leader of PAIGC, and António de Spínola, the Portuguese general responsible for the local military operations. In 1965 the war spread to the eastern part of the country and in that same year the PAIGC carried out attacks in the north of the country where at the time only the minor guerrilla movement, the Frente de Luta pela Independência Nacional da Guiné (FLING), was fighting. By that time, the PAIGC started receiving military support from the Socialist Bloc, mainly from Cuba, a support that would last until the end of the war.

    In Guinea the Portuguese troops mainly took a defensive position, limiting themselves to keeping the territories they already held. This kind of action was particularly devastating to the Portuguese troops who were constantly attacked by the forces of the PAIGC. They were also demoralised by the steady growth of the influence of the liberation supporters among the population that was being recruited in large numbers by the PAIGC.

    With some strategic changes by António Spínola in the late 1960s, the Portuguese forces gained momentum and, taking the offensive, became a much more effective force. Between 1968 and 1972, the Portuguese forces took control of the situation and sometimes carried attacks against the PAIGC positions. At this time the Portuguese forces were also adopting subversive means to counter the insurgents, attacking the political structure of the nationalist movement. This strategy culminated in the assassination of Amílcar Cabral in January 1973. Nonetheless, the PAIGC continued to fight back and pushed the Portuguese forces to the limit. This became even more visible after PAIGC received anti-aircraft weapons provided by the Soviets, especially the SA-7 rocket launchers, thus undermining the Portuguese air superiority.

    Portuguese Mozambique

    Portuguese Mozambique was the last territory to start the war of liberation. Its nationalist movement was led by the Marxist-Leninist Liberation Front of Mozambique (FRELIMO), which carried out the first attack against Portuguese targets on September 24, 1964, in Chai, province of Cabo Delgado. The fighting later spread to Niassa, Tete at the centre of the country. A report from Battalion No. 558 of the Portuguese army makes references to violent actions, also in Cabo Delgado, on August 21, 1964. On November 16 of the same year, the Portuguese troops suffered their first losses fighting in the north of the country, in the region of Xilama. By this time, the size of the guerrilla movement had substantially increased; this, along with the low numbers of Portuguese troops and colonists, allowed a steady increase in FRELIMO's strength. It quickly started moving south in the direction of Meponda and Mandimba, linking to Tete with the aid of Malawi.

    Until 1967 the FRELIMO showed less interest in Tete region, putting its efforts on the two northernmost districts of the country where the use of landmines became very common. In the region of Niassa, FRELIMO's intention was to create a free corridor to Zambézia. Until April 1970, the military activity of FRELIMO increased steadily, mainly due to the strategic work of Samora Machel in the region of Cabo Delgado. In the early 1970s, after the Portuguese Gordian Knot Operation, the nationalist guerrilla was severely damaged.

    Role of the Organisation of African Unity

    The Organisation of African Unity (OAU) was founded May 1963. Its basic principles were co-operation between African nations and solidarity between African peoples. Another important objective of the OAU was an end to all forms of colonialism in Africa. This became the major objective of the organisation in its first years and soon OAU pressure led to the situation in the Portuguese colonies being brought up at the UN Security Council.

    The OAU established a committee based in Dar es Salaam, with representatives from Ethiopia, Algeria, Uganda, Egypt, Tanzania, Zaire, Guinea, Senegal and Nigeria, to support African liberation movements. The support provided by the committee included military training and weapon supplies. The OAU also took action in order to promote the international acknowledgement of the legitimacy of the Revolutionary Government of Angola in Exile (GRAE), composed of the National Liberation Front of Angola (FNLA). This support was transferred to the People's Movement for the Liberation of Angola (MPLA) and to its leader, Agostinho Neto in 1967. In November 1972, both movements were recognised by the OAU in order to promote their merger. After 1964, the OAU recognised PAIGC as the legitimate representatives of Guinea-Bissau and Cape Verde and in 1965 recognised FRELIMO for Mozambique.

    Eritrea

    Eritrea sits on a strategic location along the Red Sea, between the Suez Canal and the Bab-el-Mandeb. Eritrea was an Italian colony from 1890–1941. On April 1, 1941, the British captured Asmara defeating the Italians and Eritrea fell under the British Military Administration. This military rule lasted from 1941 until 1952. On December 2, 1950, the United Nations General Assembly, by UN Resolution 390 A(V) federated Eritrea with Ethiopia. The architect of this federal act was the United States. The federation went into effect September 11, 1952. However, the federation was a non-starter for feudal Ethiopia, and it started to systematically undermine it. On December 24, 1958—the Eritrean flag was replaced by the Ethiopian flag; On May 17, 1960—The title "Government of Eritrea" of the Federation was changed to "Administration of Eritrea". Earlier Amharic was declared official language in Eritrea replacing Tigrinya and Arabic. Finally on November 14, 1962 -– Ethiopia officially annexed Eritrea as its 14th province.

    The people of Eritrea, after finding out peaceful resistance against Ethiopia's rule was falling on deaf ears formed the Eritrean Liberation Movement (ELM) which was formed in 1958. The founders of these independence movement were: Mohammad Said Nawud, Saleh Ahmed Iyay, Yasin al-Gade, Mohammad al-Hassen and Said Sabr. ELM members were organised in secret cells of seven. The movement was known as Mahber Shewate in Tigrinya and as Harakat Atahrir al Eritrea in Arabic. On July 10, 1960, a second independence movement, the Eritrean Liberation Front (ELF) was founded in Cairo. Among its founders were: Idris Mohammed Adem, President, Osman Salih Sabbe, Secretary General, and Idris Glawdewos as head of military affairs. These were among those who made up the highest political body known as the Supreme Council. On September 1, 1961, Hamid Idris Awate and his ELF unit attacked an Ethiopian police unit in western Eritrea (near Mt. Adal). This heralded the 30-year Eritrean war for independence. Between March and November 1970, three core groups that later made up the Eritrean People's Liberation Front (EPLF) split from the ELF and established themselves as separate units.

    In September 1974, Emperor Haile Selassie was overthrown by a military coup in Ethiopia. The military committee that took power in Ethiopia is better known by its Amharic name the Derg. After the military coup the Derg broke ties with the U.S. and realigned itself with the USSR (Union of Soviet Socialist Republics) and the USSR and its eastern bloc allies replaced America as patrons of Ethiopia's aggression against Eritrea. Between January and July 1977, the ELF and EPLF armies had liberated 95% of Eritrea capturing all but 4 towns. However, in 1978–79, Ethiopia mounted a series of five massive Soviet-backed offensives and reoccupied almost all of Eritrea's major towns and cities, except for Nakfa. The EPLF withdrew to a mountain base in northern Eritrea, around the town of Nakfa. In 1980 the EPLF had offered a proposal for referendum to end the war, however, Ethiopia, thinking it had a military upper hand, rejected the offer and war continued. In February–June 1982, The EPLF managed to repulse Ethiopia's much heralded four-month "Red Star" campaign (aka the 6th offensive by Eritreans) inflicting more than 31,000 Ethiopian casualties. In 1984 the EPLF started its counter-offensive and cleared the Ethiopian from the North-eastern Sahil front. In March 1988 the EPLF demolished the Ethiopian front at Afabet in a major offensive the British Historian Basil Davidson compared to the French defeat at Dien Bien Phu. In February 1990 the EPLF liberated the strategic port of Massawa and in the process destroyed a portion of the Ethiopian Navy. A year later the war came to conclusion on May 24, 1991, when the Ethiopian army in Eritrea surrendered. Thus Eritrea's 30-year war crowned with victory.

    On May 24, 1993, after a UN-supervised referendum on April 23–25, 1993, in which the Eritrean people overwhelmingly, 99.8%, voted for independence, Eritrea officially declared its independence and gained international recognition.

    At the onset of World War I, the Union of South Africa participated in the invasion and occupation of several Allied territories taken from the German Empire, most notably German South-West Africa and German East Africa (Tanzania). Germany's defeat forced the new Weimar Republic to cede its overseas possessions to the League of Nations as mandates. A mandate over South-West Africa was conferred upon the United Kingdom, "for and on behalf of the government of the Union of South Africa", which was to handle administrative affairs under the supervision of the league. South-West Africa was classified as a "C" mandate, or a territory whose population sparseness, small size, remoteness, and geographic continuity to the mandatory power allowed it to be governed as an integral part of the mandatory itself. Nevertheless, the League of Nations obliged South Africa to promote social progress among indigenous inhabitants, refrain from establishing military bases there, and grant residence to missionaries of any nationality without restriction. Article 7 of the South-West Africa mandate stated that the consent of the league was required for any changes in the terms of the mandate.

    With regards to the local German population, the occupation was on especially lenient terms; South Africa only repatriated civil and military officials, along with a small handful of political undesirables. Other German civilians were allowed to remain. In 1924 all white South-West Africans were automatically naturalised as South African nationals and British subjects thereof; the exception being about 260 who lodged specific objections. In 1926 a Legislative Assembly was created to represent German, Afrikaans, and English-speaking white residents. Control over basic administrative matters, including taxation, was surrendered to the new assembly, while matters pertaining to defence and native affairs remained in the hands of an administrator-general.

    Following World War II, South-West Africa's international status after the dissolution of the League of Nations was questioned. The United Nations General Assembly refused South Africa permission to incorporate the mandate as a fifth province, largely due to its controversial policy of racial apartheid. At the General Assembly's request the issue was examined at the International Court of Justice. The court ruled in 1950 that South Africa was not required to transfer the mandate to UN trusteeship, but remained obligated to adhere to its original terms, including the submission of annual reports on conditions in the territory.

    Led by newly elected Afrikaner nationalist Daniel François Malan, the South African government rejected this opinion and refused to recognise the competence of the UN to interfere with South-West African affairs. In 1960 Ethiopia and Liberia, the only two other former League of Nations member states in Africa, petitioned the Hague to rule in a binding decision that the league mandate was still in force and to hold South Africa responsible for failure to provide the highest material and moral welfare of black South-West Africans. It was pointed out that nonwhite residents were subject to all the restrictive apartheid legislation affecting nonwhites in South Africa, including confinement to reserves, colour bars in employment, pass laws, and influx control over urban migrants. A South African attempt to scupper proceedings by arguing that the court had no jurisdiction to hear the case was rejected; conversely, however, the court itself ruled that Ethiopia and Liberia did not possess the necessary legal interest entitling them to bring the case.

    In October 1966 the General Assembly declared that South Africa had failed to fulfill its obligations as the mandatory power and had in fact disavowed them. The mandate was unilaterally terminated on the grounds that the UN would now assume direct responsibility for South-West Africa. In 1967 and 1969 the UN called for South Africa's disengagement and requested the Security Council to take measures to oust the South African Defence Force from the territory that the General Assembly, at the request of black leaders in exile, had officially renamed Namibia. One of the greatest aggravating obstacles to eventual independence occurred when the UN also agreed to recognise the South West African People's Organization (SWAPO), then an almost exclusively Ovambo body, as the sole authentic representative of the Namibian population. South Africa was offended by the General Assembly's simultaneous dismissal of its various internal Namibian parties as puppets of the occupying power. Furthermore, SWAPO espoused a militant platform which called for independence through UN activity, including military intervention.

    By 1965 SWAPO's morale had been elevated by the formation of a guerrilla wing, the People's Liberation Army of Namibia (PLAN), which forced the deployment of South African Police troops along the long and remote northern frontier. The first armed clashes between PLAN cadres and local security forces took place in August 1966.
