Answer: World history or global history as a field of historical research examines history from a global perspective. It started centuries ago. The main practitioners were Voltaire (1694–1778), Hegel (1770–1831), (1818–1883) and Arnold J. Toynbee (1889–1975). This field was in the second half of the 20th century. It deals with the history of multiple cultures and countries, like world history, but should not be confused with comparative history, which is not global. World history is looking for common patterns that appear in all cultures. World historians have two main points: integration (how the process of world history connects people in the world) and difference (how patterns of world history reveal the diversity of human experience). Use a thematic approach with a lot of emphasis.
