World history (field)

World history or global history as a field of historical study examines history from a global perspective. It emerged centuries ago; leading practitioners have included Voltaire (1694–1778), Hegel (1770–1831), Karl Marx (1818–1883), Oswald Spengler (1880–1936), and Arnold J. Toynbee (1889–1975). The field became much more active (in terms of university teaching, text books, scholarly journals, and academic associations) in the late 20th century. It is not to be confused with comparative history, which, like world history, deals with the history of multiple cultures and nations, but does not do so on a global scale. World history looks for common patterns that emerge across all cultures. World historians use a thematic approach, with two major focal points: integration (how processes of world history have drawn people of the world together) and difference (how patterns of world history reveal the diversity of the human experience). World history in the Western tradition is commonly divided into three parts, viz. ancient, medieval, and modern time. The division on ancient and medieval periods is less sharp or absent in the Arabic and Asian historiographies. A synoptic view of universal history led some scholars, beginning with Karl Jaspers, to distinguish the Axial Age synchronous to "classical antiquity" of the Western tradition. Jaspers also proposed a more universal periodization—prehistory, history and planetary history. All distinguished earlier periods belong to the second period (history) which is a relatively brief transitory phase between two much longer periods. Jerry H. Bentley (2011) 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, among others. Marnie Hughes-Warrington (2005) reasoned that "world history" is often mistaken to encompass the entire Earth, because works claiming to be "world histories" may have in practice a more limited scope, depending on the author's perspective: 'The "world" in world history (.
