To commemorate and celebrate the contributions to our nation made by people of African descent, American historian Carter G. Woodson established Black History Week. The first celebration occurred on Feb. 12, 1926. For many years, the second week of February was set aside for this celebration to coincide with the birthdays of abolitionist/editor Frederick Douglass and Abraham Lincoln. In 1976, as part of the nation's bicentennial, the week was expanded into Black History Month. Each year, U.S. presidents proclaim February as National African-American History Month.  Read a summary of updated demographic data on this population below.
