Black History Month is an annual observance originating in the United States, where it is also known as African-American History Month. It has received official recognition from governments in the United States and Canada and more recently has been observed during October in Ireland, the Netherlands, and the United Kingdom. Black History Month marks achievements made by African Americans and is a time for recognizing their central role 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.
