Florida Territory
Beginning in late 1835, Osceola and the Seminole allies began a guerrilla war against the U.S. forces. Numerous generals fought and failed, succumbing to the heat and disease as well as lack of knowledge of the land. It was not until General Thomas Jesup captured many of the key Seminole chiefs, including Osceola who died in captivity of illness, that the battles began to die down. The Seminoles were eventually forced to migrate. Florida joined the Union as the 27th state on March 3, 1845. By this time, almost all of the Seminoles were gone, except for a small group living in the Everglades.

Florida remained an organized territory of the United States until 1845, when it was admitted into the Union as the State of Florida. The Territorial Period (1821-1845) was marked by protracted wars with the Creek Indian groups who occupied the peninsula, collectively known as "Seminoles", during the Second Seminole War (1835-1842). The United States Army took command of the Castillo de San Marcos and renamed it Fort Marion after General Francis Marion, who fought in the American Revolutionary War. The capital of the territory was moved to Tallahassee in 1824.
