Fort Mose was the first free African American settlement in America. Today, it is a National Historical landmark on the Florida Black Heritage Trail. You can find it (if you're lucky) just north of St. Augustine. It's not very well marked.
More than a century before the Emancipation Proclamation, British slaves were granted freedom in Florida . . . if they proclaimed their allegiance to the Spanish and the Catholic church (yea, that's right, there was a catch). In 1738, the Spanish governor of Florida chartered Fort Mose as a settlement for freed Africans. The settlement, located in the Florida marshland north of the Spanish fort, the Castillo San Marcos, was home to 100 free African Americans (or would that be African-Spanish-Floridians?) who grew their own food, built homes and joined the Spanish in defending their freedom from British invasion.
And you thought we were just a battleground state!
