February is Black History Month in the United States and Canada. Since 1976, the month has been designated to remember the contributions of people of the African Diaspora. Historian Carter G. Woodson launched the holiday because contributions that African Americans have made to U.S. culture and society are largely omitted from and overlooked in history books.
