Escaped slaves became Spanish Florida's first settlers. They joined refugees from the Creek Nation and called themselves Seminoles which means runaways. Intermixing became so common that they were soon called Black Seminoles. The black Seminoles struck frequently against slave plantations and runaway slaves swelled their ranks. The U.S. government launched three massive war campaigns against the Seminole nation over a period of 40 years. The second war alone cost the U.S. government over 40 million dollars and 1500 soldiers. The Seminoles eventually signed a peace treaty with President Polk which was violated in 1849 when the U.S. Attorney General ruled that black Seminoles were still slaves under U.S. law.
