We can thank Carter G. Woodson, often described as the "father of Black history," for Black History Month. He started a week-long event in February 1926 which later turned into the month-long event we have today.
This video about Carter G. Woodson by One Mic History is less than 19 minutes, and worth watching: https://youtu.be/yDsgf3u3rEo
In fact, this entire 81-video playlist is good.

I'll be watching these myself this month, and I've got many more video playlists queued up!
