Establishment and parameters of the field
Jerry H. Bentley has observed that 'the term world history has never been a clear signifier with a stable referent', and that usage of the term overlaps with universal history, comparative history, global history, big history, macro history, and transnational history, amongst others.
The advent of world history as a distinct academic field of study
 can be traced to the 1960s, but the pace quickened in the 1980s.
 A key step was the creation of the World History Association and 
graduate programs at a handful of universities. Over the next decades 
scholarly publications, professional and academic organizations, and 
graduate programs in World History proliferated. World History has often
 displaced Western Civilization in the required curriculum of American 
high schools and universities, and is supported by new textbooks with a 
world history approach. 
World History attempts to recognise and address two structures that have profoundly shaped professional history-writing:
- A tendency to use current nation-states to the set the boundaries and agendas of studies of the past.
 - A deep legacy of Eurocentric assumptions (found especially, but not only, in Western history-writing).
 
Thus World History tends to study networks, connections, and systems 
that cross traditional boundaries of historical study like linguistic, 
cultural, and national borders. World History is often concerned to 
explore social dynamics that have led to large-scale changes in human 
society, such as industrialisation and the spread of capitalism,
 and to analyse how large-scale changes like these have affected 
different parts of the world. Like other branches of history-writing in 
the second half of the twentieth century, World History has a scope far 
beyond historians' traditional focus on politics, wars, and diplomacy, 
taking in a panoply of subjects like gender history, social history, cultural history, and environmental history.

History
Pre-modern
The
 study of world history, as distinct from national history, has existed 
in many world cultures. However, early forms of world history were not 
truly global, and were limited to only the regions known by the 
historian. 
In Ancient China, Chinese world history, that of China and the surrounding people of East Asia, was based on the dynastic cycle articulated by Sima Qian in circa 100 BC. Sima Qian's model is based on the Mandate of Heaven. Rulers rise when they united China, then are overthrown when a ruling dynasty became corrupt.
 Each new dynasty begins virtuous and strong, but then decays, provoking
 the transfer of Heaven's mandate to a new ruler. The test of virtue in a
 new dynasty is success in being obeyed by China and neighboring 
barbarians. After 2000 years Sima Qian's model still dominates 
scholarship, although the dynastic cycle is no longer used for modern Chinese history.
In Ancient Greece, Herodotus (5th century BC), as founder of Greek historiography,
 presents insightful and lively discussions of the customs, geography, 
and history of Mediterranean peoples, particularly the Egyptians. 
However, his great rival Thucydides
 promptly discarded Herodotus's all-embracing approach to history, 
offering instead a more precise, sharply focused monograph, dealing not 
with vast empires over the centuries but with 27 years of war between 
Athens and Sparta. In Rome, the vast, patriotic history of Rome by Livy 
(59 BC-17 AD) approximated Herodotean inclusiveness; Polybius (c.200-c.118 BC) aspired to combine the logical rigor of Thucydides with the scope of Herodotus.
In Central Asia, The Secret History of Mongols
 is regarded as the single significant native Mongolian account of 
Genghis Khan. The Secret History is regarded as a piece of classic 
literature in both Mongolia and the rest of the world. 
In the Middle East, Ala'iddin Ata-Malik Juvayni
 (1226–1283) was a Persian historian who wrote an account of the Mongol 
Empire entitled Ta' rīkh-i jahān-gushā (History of the World Conqueror).
 The standard edition of Juvayni is published under the title Ta' rīkh-i
 jahān-gushā, ed. Mirza Muhammad Qazwini, 3 vol, Gibb Memorial Series 16
 (Leiden and London, 1912–37). An English translation by John Andrew 
Boyle "The History of the World-Conqueror" was republished in 1997. 
Rashīd al-Dīn Fadhl-allāh Hamadānī
 (1247–1318), was a Persian physician of Jewish origin, polymathic 
writer and historian, who wrote an enormous Islamic history, the Jami 
al-Tawarikh, in the Persian language, often considered a landmark in 
intercultural historiography and a key document on the Ilkhanids (13th 
and 14th century).
 His encyclopedic knowledge of a wide range of cultures from Mongolia to
 China to the Steppes of Central Eurasia to Persia, the Arabic-speaking 
lands, and Europe, provide the most direct access to information on the 
late Mongol era. His descriptions also highlight the manner in which the
 Mongol Empire and its emphasis on trade resulted in an atmosphere of 
cultural and religious exchange and intellectual ferment, resulting in 
the transmission of a host of ideas from East to West and vice versa. 
One Muslim scholar, Ibn Khaldun (1332-1409) broke with traditionalism and offered a model of historical change in Muqaddimah,
 an exposition of the methodology of scientific history. Ibn Khaldun 
focused on the reasons for the rise and fall of civilization, arguing 
that the causes of change are to be sought in the economic and social 
structure of society. His work was largely ignored in the Muslim world.
 Otherwise the Muslim, Chinese and Indian intellectuals held fast to a 
religious traditionalism, leaving them unprepared to advise national 
leaders on how to confront the European intrusion into Asia after 1500 
AD.
Early modern
During the Renaissance in Europe, history was written about states or nations. The study of history changed during the Enlightenment and Romanticism. Voltaire
 described the history of certain ages that he considered important, 
rather than describing events in chronological order. History became an 
independent discipline. It was not called philosophia historiae anymore, but merely history (historia).Voltaire,
 in the 18th century, attempted to revolutionize the study of world 
history. First, Voltaire concluded that the traditional study of history
 was flawed. The Christian Church, one of the most powerful entities in 
his time, had presented a framework for studying history. Voltaire, when
 writing History of Charles XII (1731) and The Age of Louis XIV (1751), instead choose to focus economics, politics and culture.
 These aspects of history were mostly unexplored by his contemporaries 
and would each develop into their own sections of world history. Above 
all else, Voltaire regarded truth as the most essential part of 
recording world history. Nationalism and religion only subtracted from 
objective truth, so Voltaire freed himself for their influence when he 
recorded history.
Giambattista Vico (1668–1744) in Italy wrote Scienza nuva seconda
 (The New Science) in 1725, which argued history as the expression of 
human will and deeds.  He thought that men are historical entities and 
that human nature changes over time. Each epoch should be seen as a 
whole in which all aspects of culture—art, religion, philosophy, 
politics, and economics—are interrelated (a point developed later by Oswald Spengler).
 Vico showed that myth, poetry, and art are entry points to discovering 
the true spirit of a culture. Vico outlined a conception of historical 
development in which great cultures, like Rome, undergo cycles of growth
 and decline.  His ideas were out of fashion during the Enlightenment, but influenced the Romantic historians after 1800. 
A major theoretical foundation for world history was given by German philosopher G. W. F. Hegel, who saw the modern Prussian state as the latest (though often confused with the highest) stage of world development. 
G.W.F. Hegel developed three lenses through which he believed 
world history could be viewed. Documents produced during a historical 
period, such as journal entries and contractual agreements, were 
considered by Hegel to be part of Original History. These documents are 
produced by a person enveloped within a culture, making them conduits of
 vital information but also limited in their contextual knowledge. 
Documents which pertain to Hegel’s Original History are classified by 
modern historians as primary sources.
Reflective History, Hegel’s second lens, are documents written 
with some temporal distance separating the event which is discussed in 
the academic writing. What limited this lens, according to Hegel, was 
the imposition of the writers own cultural values and views on the 
historical event. This criticism of Reflective History was later 
formalized by Anthropologists Franz Boa and coined as Cultural 
relativism by Alain Locke. Both of these lenses were considered to be 
partially flawed by Hegel.
Hegel termed the lens which he advocated to view world history 
through as Philosophical History.  In order to view history through this
 lens, one must analyze events, civilizations, and periods objectively. 
When done in this fashion, the historian can then extract the prevailing
 theme from their studies. This lens differs from the rest because it is
 void of any cultural biases and takes a more analytical approach to 
history. World History can be a broad topic, so focusing on extracting 
the most valuable information from certain periods may be the most 
beneficial approach. This third lens, as did Hegel’s definitions of the 
other two, affected the study of history in the early modern period and 
our contemporary period.
Another early modern historian was Adam Ferguson. Ferguson’s main contribution to the study of world history was his An Essay on the History of Civil Society (1767).
 According to Ferguson, world history was a combination of two forms of 
history. One was natural history; the aspects of our world which god 
created. The other, which was more revolutionary, was social history. 
For him, social history was the progress humans made towards fulfilling 
God’s plan for humanity. He believed that progress, which could be 
achieved through individuals pursuing commercial success, would bring us
 closer to a perfect society; but we would never reach one.
 However, he also theorized that a complete dedication to commercial 
success could lead to societal collapse—like what happened in 
Rome—because people would lose morality. Through this lens, Ferguson 
viewed world history as humanities struggle to reach an ideal society.
Henry Home, Lord Kames was a philosopher during the Enlightenment
 and contributed to the study or world history. In his major historical 
work, Sketches on the History of Man, Home’s outlined the four stages of human history which he observed.
 The first and most primitive stage was small hunter-gatherer groups. 
Then, in order to form larger groups, humans transitioned into the 
second stage when they began to domesticate animals. The third stage was
 the development of agriculture. This new technology established trade 
and higher levels of cooperation amongst sizable groups of people. With 
the gathering of people into agricultural villages, laws and social 
obligations needed to be developed so a form of order could be 
maintained. The fourth, and final stage, involved humans moving into 
market towns and seaports where agriculture was not the focus. Instead, 
commerce and other forms of labor arouse in a society. By defining the 
stages of human history, Homes influenced his successors. He also 
contributed to the development of other studies such as sociology and 
anthropology.
Contemporary
World history became a popular genre in the 20th century with universal history. In the 1920s, several best-sellers dealt with the history of the world, including surveys The Story of Mankind (1921) by Hendrik Willem van Loon and The Outline of History (1918) by H.G. Wells. Influential writers who have reached wide audiences include H. G. Wells, Oswald Spengler, Arnold J. Toynbee, Pitirim Sorokin, Carroll Quigley, Christopher Dawson, and Lewis Mumford. Scholars working the field include Eric Voegelin, William Hardy McNeill and Michael Mann.
 With evolving technologies such as dating methods and surveying laser 
technology called LiDAR, contemporary historians have access to knew 
information which changes how past civilizations are studied. 
Spengler's Decline of the West
 (2 vol 1919–1922) compared nine organic cultures: Egyptian (3400 
BC-1200 BC), Indian (1500 BC-1100 BC), Chinese (1300 BC-AD 200), 
Classical (1100 BC-400 BC), Byzantine (AD 300–1100), Aztec (AD 
1300–1500), Arabian (AD 300–1250), Mayan (AD 600–960), and Western (AD 
900–1900). His book was a smashing success among intellectuals worldwide
 as it predicted the disintegration of European and American 
civilization after a violent "age of Caesarism," arguing by detailed 
analogies with other civilizations. It deepened the post-World War I 
pessimism in Europe, and was warmly received by intellectuals in China, 
India, and Latin America who hoped his predictions of the collapse of 
European empires would soon come true.
In 1936–1954, Toynbee's ten-volume A Study of History
 came out in three separate installments. He followed Spengler in taking
 a comparative topical approach to independent civilizations. Toynbee 
said they displayed striking parallels in their origin, growth, and 
decay. Toynbee rejected Spengler's biological model of civilizations as 
organisms with a typical life span of 1,000 years. Like Sima Qian,
 Toynbee explained decline as due to their moral failure. Many readers 
rejoiced in his implication (in vols. 1–6) that only a return to some 
form of Catholicism could halt the breakdown of western civilization 
which began with the Reformation. Volumes 7–10, published in 1954, 
abandoned the religious message, and his popular audience slipped away, 
while scholars  picked apart his mistakes.
McNeill wrote The Rise of the West
 (1963) to improve upon Toynbee by showing how the separate 
civilizations of Eurasia interacted from the very beginning of their 
history, borrowing critical skills from one another, and thus 
precipitating still further change as adjustment between traditional old
 and borrowed new knowledge and practice became necessary. McNeill took a
 broad approach organized around the interactions of peoples across the 
Earth. Such interactions have become both more numerous and more 
continual and substantial in recent times. Before about 1500, the 
network of communication between cultures was that of Eurasia. The term 
for these areas of interaction differ from one world historian to 
another and include world-system and ecumene.  Whatever it is called, the importance of these intercultural contacts has begun to be recognized by many scholars.
History education
United States
T. Walter Wallbank and Alastair M. Taylor co-authored Civilization Past & Present,
 the first world-history textbook published in the United States (1942).
 With additional authors, this very successful work went through 
numerous editions up to the first decade of the twenty-first century. 
According to the Golden Anniversary edition of 1992, the ongoing 
objective of Civilization Past & Present "was to present a 
survey of world cultural history, treating the development and growth of
 civilization not as a unique European experience but as a global one 
through which all the great culture systems have interacted to produce 
the present-day world. It attempted to include all the elements of 
history – social, economic, political, religious, aesthetic, legal, and 
technological." In college curricula of the United States, world history became a popular replacement for courses on Western Civilization. Professors Patrick Manning, previously of Northeastern University and now at the University of Pittsburgh's World History Center; and Ross E. Dunn at San Diego State are leaders in promoting innovative teaching methods.
In schools of architecture in the U.S., the National Architectural Accrediting Board
 now requires that schools teach history that includes a non-west or 
global perspective. This reflects a decade-long effort to move past the 
standard Euro-centric approach that had dominated the field.
Recent themes
In
 recent years, the relationship between African and world history has 
shifted rapidly from one of antipathy to one of engagement and 
synthesis. Reynolds (2007) surveys the relationship between African and 
world histories, with an emphasis on the tension between the area 
studies paradigm and the growing world-history emphasis on connections 
and exchange across regional boundaries. A closer examination of recent 
exchanges and debates over the merits of this exchange is also featured.
 Reynolds sees the relationship between African and world history as a 
measure of the changing nature of historical inquiry over the past 
century.
Marxian theory of history
The Marxist theory of historical materialism claims the history of the world is fundamentally determined by the material conditions
 at any given time – in other words, the relationships which people have
 with each other in order to fulfil basic needs such as feeding, 
clothing and housing themselves and their families. Overall, Marx and Engels claimed to have identified five successive stages of the development of these material conditions in Western Europe.
The theory divides the history of the world into the following periods: Primitive communism; Slave society; Feudalism; Capitalism; and Socialism. 
Regna Darnell and Frederic Gleach argue that, in the Soviet 
Union, the Marxian theory of history was the only accepted orthodoxy, 
and stifled research into other schools of thought on history.  However, adherents of Marx's theories argue that Stalin distorted Marxism.
