Carter G. Woodson and the Association for the Study of Negro Life and History established Negro History Week in 1926, celebrating important dates like Abraham Lincoln's and Fredrick Douglas's birthdays. In 1969, the Black United Students Organization at Kent University extended it to Black History Month. President Gerald Ford recognized this in 1976. Throughout the 1980s, various Black student and cultural organizations successfully petitioned governors and mayors to officially recognize February as Black History Month and integrate African American history into public school curriculums.
