The Black Seminoles are black Indians associated with the Seminole people in Florida and Oklahoma. They are the descendants of free blacks and of escaped slaves (called maroons) who allied with Seminole groups in Spanish Florida. Historically, the Black Seminoles lived mostly in distinct bands near the Native American Seminole. Some were held as slaves of particular Seminole leaders; but they had more freedom than did slaves held by whites in the South and by other Native American tribes, including the right to bear arms.

The Black Seminole culture that took shape after 1800 was a dynamic mixture of African, Native American, Spanish, and slave traditions. Adopting certain practices of the Native Americans, maroons wore Seminole clothing and ate the same foodstuffs prepared the same way: they gathered the roots of a native plant called coontie, grinding, soaking, and straining them to make a starchy flour similar to arrowroot, as well as mashing corn with a mortar and pestle to make sofkee, a sort of porridge often used as a beverage, with water added-- ashes from the fire wood used to cook the sofkee were occasionally added to it for extra flavor. They also introduced their Gullah staple of rice to the Seminole, and continued to use it as a basic part of their diets. Rice remained part of the diet of the Black Seminoles who moved to Oklahoma.  Initially living apart from the Native Americans, the maroons developed their own unique African-American culture, based in the Gullah culture of the Lowcountry. Black Seminoles inclined toward a syncretic form of Christianity developed during the plantation years. Certain cultural practices, such as "jumping the broom" to celebrate marriage, hailed from the plantations; other customs, such as some names used for black towns, reflected African heritage.  As time progressed, the Seminole and Blacks had limited intermarriage, but historians and anthropologists have come to believe that generally the Black Seminoles had independent communities. They allied with the Seminole at times of war. The Seminole society was based on a matrilineal kinship system, in which inheritance and descent went through the maternal line. Children were considered to belong to the mother's clan, so those born to ethnic African mothers would have been considered black by the Seminole. While the children might integrate customs from both parents' cultures, the Seminole believed they belonged to the mother's group more than the father's.  African Americans adopted some elements of the European-American patriarchal system. But, under the South's adoption of the principle of partus sequitur ventrem in the 17th century and incorporated into slavery law in slave states, children of slave mothers were considered legally slaves. Under the Fugitive Slave Law of 1850, even if the mother escaped to a free state, she and her children were legally considered slaves and fugitives. As a result, the Black Seminoles born to slave mothers were always at risk from slave raiders.
