Black History Month is an annual observance remembering important people and events in the history of the African diaspora as well as recognizing the central role of African Americans in U.S. history. Also known as African American History Month, the event grew out of "Negro History Week," the brainchild of noted historian Carter G. Woodson and other prominent African Americans. Since 1976, every U.S. president has officially designated the month of February as Black History Month. Other countries around the world, including Canada and the United Kingdom, also devote a month to celebrating Black history.
