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.
St. Francisville, Louisiana
At the end of the American Revolutionary War, Great Britain ceded what it called West Florida to Spain in 1783, as part of the Treaty of Paris. There were years of contention as to exactly where the eastern boundary of the 1803 Louisiana Purchase was—depending on which treaty was cited, as France, Great Britain, and Spain had redrawn the boundaries among themselves during the second half of the 18th century. Spain continued to claim territory on the eastern side of the Mississippi River until it and the United States settled this issue in the Pinckney Treaty. This region is today called the Florida Parishes.
