Black History Month is observed each February to celebrate the achievements of African Americans. It began as Negro History Week in 1926, proposed by Dr. Carter G. Woodson to honor black history and contributions. Woodson chose the second week of February to coincide with the birthdays of Abraham Lincoln and Frederick Douglass. It was later expanded to a full month. The presentation discussed important abolitionists, civil rights leaders, inventors, scientists, athletes and shared the history of the presenter's family dating back to slavery and the post-Civil War period.
