The story of Fort Mosé

Fort Mose (originally known as Gracia Real de Santa Teresa de Mose [Royal Grace of Saint Teresa of Mose], and later as Fort Mose, or alternatively Fort Moosa or Fort Mossa) is a former Spanish fort in St. Augustine, Florida. In 1738, the governor of Spanish Florida, Manuel de Montiano, had the fort established as a free black settlement, the first to be legally sanctioned in what would become the territory of the United States.

Fort Mosé started with soldiers before it had settlers — the frontier's usual order of operations.
