The story of Black History Month begins in 1915, half a century after the Thirteenth Amendment abolished slavery in the United States. That September, the Harvard-trained historian Carter G. Woodson and the prominent minister Jesse E. Moorland founded the Association for the Study of Negro Life and History (ASNLH), an organization dedicated to researching and promoting achievements by black Americans and other peoples of African descent. Known today as the Association for the Study of African American Life and History (ASALH), the group sponsored a national Negro History week in 1926, choosing the second week of February to coincide with the birthdays of Abraham Lincoln and Frederick Douglass. The event inspired schools and communities nationwide to organize local celebrations, establish history clubs and host performances and lectures.
In 1975, President Ford issued a Message on the Observance of Black History Week urging all Americans to "recognize the important contribution made to our nation's life and culture by black citizens." In 1976 this commemoration of black history in the United States was expanded by ASALH to Black History Month, also known as African American History Month, and President Ford issued the first Message on the Observance of Black History Month that year. Since 1976, every U.S. president has officially designated the month of February as Black History Month.
