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.
Orange County, Florida
Immediately following the transfer of Florida to the United States in 1821, Governor Andrew Jackson created two counties: Escambia to the west of the Suwannee River and St. Johns to the east. In 1824, the area to the south of St. Johns County was organized as Mosquito County, and Enterprise was named its county seat. This large county took up much of central Florida. It was renamed as Orange County in 1845 when Florida became a state. After population increased in the region, the legislature organized several counties, such as Osceola, Seminole, Lake, and Volusia, from its territory.
