African Americans have an integral part in the history of the American Revolution, from Crispus Attucks, the Black Minutemen in Massachusetts, to the 1st Rhode Island Regiment. Here are some of the best resources I've found on the Web about African Americans in the Revolutionary War:
- AmericanRevolution.com: African Americans in the Revolutionary Period
- Wikipedia: African Americans in the American Revolution [category index of various Wikipedia articles]
- PBS.org: Africans in America: The Revolutionary War
This list of resources is of course by no means exhaustive, but it should be enough to get you started on researching the topic. I'll add to this list as I come across more quality resources.
