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 Parishes
Following the American Revolutionary War, West Florida was the subject of a border dispute between the newly-formed United States and Spain, which acquired West and East Florida from the British after the war. The dispute led American and British settlers in the part of West Florida west of the Perdido River to declare an independent Republic of West Florida in 1810 and elected their leader, Fulwar Skipwith, as president. (None of the short-lived Republic of West Florida lay within the boundaries of the modern state of Florida.) The flag of the Republic of West Florida, which is often identified with the Bonnie Blue Flag of the Civil War era, flies on many public buildings in the Florida Parishes. In 2006 the state legislature designated it the "official flag of the Republic of West Florida Historic Region."
