The Seminole Nation of Oklahoma is a federally recognized Native American tribe based in the U.S. state of Oklahoma. It is the largest of the three federally recognized Seminole governments, which include the Seminole Tribe of Florida and the Miccosukee Tribe of Indians of Florida. Its citizens are descendants of the approximately 3,000 Seminoles who were forcibly removed from Florida to Indian Territory, along with 800 Black Seminoles, after the Second Seminole War. The Seminole Nation of Oklahoma is headquartered in Wewoka within Seminole County, Oklahoma. Of 18,800 enrolled tribal citizens, 13,533 live in Oklahoma. The tribe began to revive its government in 1936 under the Indian Reorganization Act. While its reservation was originally larger, today the tribal reservation and jurisdictional area covers Seminole County, Oklahoma, within which it has a variety of properties.
