Escaped enslaved people would want to fight on the side of the Seminole
became known as Black Seminoles. How would the transfer of Florida
from Spain to the United States have affected the Black Seminole? *

Black Seminoles, also called Seminole Maroons or Seminole Freedmen, a group of free blacks and runaway slaves (maroons) that joined forces with the Seminole Indians in Florida from approximately 1700 through the 1850s. The Black Seminoles were celebrated for their bravery and tenacity during the three Seminole Wars.

The Native American Seminoles living in Florida were not one tribe but many. They spoke a variety of Muskogean languages and had formed an alliance to prevent European settlers from expanding into their homelands. The word they used to describe themselves—Seminole—is derived from a Creek word meaning “separatist” or “runaway.” Because slavery had been abolished in 1693 in Spanish Florida, that territory became a safe haven for runaway slaves. Throughout the 18th century, many free blacks and runaway slaves went to Florida and lived in harmony with the Seminoles. Their proximity to and resulting collaboration with the Seminoles led students of the group to refer to them as Black Indians, Black Seminoles, and eventually—especially among scholars—Seminole Maroons, or Seminole Freedmen.
