Approaching World History
These standards rest on the premise that our schools must teach a comprehensive history in which all students may share. That means a history that encompasses humanity. In writing the standards a primary task was to identify those developments in the past that involved and affected relatively large numbers of people and that had broad significance for later generations. Some of these developments pertain to particular civilizations or regions. Others involve patterns of human interconnection that extended across cultural and political boundaries. Within this framework students are encouraged to explore in depth particular cases of historical change that may have had only regional or local importance but that exemplify the drama and human substance of the past. 

These standards represent a forceful commitment to world-scale history. No attempt has been made, however, to address the histories of all identifiable peoples or cultural traditions. The aim rather is to encourage students to ask large and searching questions about the human past, to compare patterns of continuity and change in different parts of the world, and to examine the histories and achievements of particular peoples or civilizations with an eye to wider social, cultural, or economic contexts. 

Periodization for World History 

As in United States History, arranging the study of the past into distinct periods of time is one way of imposing a degree of order and coherence on the incessant, fragmented flow of events. Historians have devised a variety of periodization designs for World History to make it intelligible. Students should understand that every one of these designs is a creative construction reflecting the historian’s particular aims, preferences, and cultural or social values. 

A periodization of world history that encompasses the grand sweep of the human past can make sense only at a relatively high level of generalization. Historians have also worked out periodizations for particular civilizations, regions, and nations, and these have their own validity, their own benchmarks and turning points. The history of India, for example, would necessarily be periodized differently than would the history of China or Europe, since the major shifts in Indian history relate to the Gupta age, the Mughal empire, the post-independence era, and so on. 

We believe that as teachers work toward a more integrated study of world history in their classrooms they will appreciate having a periodization design that encourages study of those broad developments that have involved large segments of the world’s population and that have had lasting significance. The standards are divided into nine eras of world history. The title of each era attempts to capture the very general character of that age. Note that the time periods of some of the eras overlap in order to incorporate both the closure of certain developments and the start of others. The beginning and ending dates should be viewed as approximations representing broad shifts in the human scene.
