Chronological Thinking: Historical Periodization

History is a vast subject. To make studying it more manageable, historians divide the past into periods. A period is a defined block of time; the years included in a period have something in common, but what that common factor is may vary. Some periods are based on important events (The Revolutionary War); others on cultural trends (The Roaring Twenties), a decade (the 1990s), or a prominent person of the time (Napoleon). Often, periods overlap—one period is ending while another begins.

The scholars who put together the Special Presentation, The African American Odyssey: A Quest for Full Citizenship, organized the historical information into sections that could be considered periods. Study the description of these sections in the Exhibition Overview.
