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.
British America
British America gained large amounts of new territory following the Treaty of Paris (1763) which ended the French and Indian War in America, and ended British involvement in the Seven Years' War in Europe. At the start of the Revolutionary War in 1775, the British Empire included 20 colonies north and east of New Spain, including areas of Mexico and the Western United States. East and West Florida were ceded to the Kingdom of Spain in the Treaty of Paris (1783) which ended the American Revolution, and then ceded by Spain to the United States in 1819 after treaty negotiations to settle the old southwest border with Spanish Florida (eastern Louisiana, southern Alabama, Mississippi, and western Georgia). The remaining continental colonies of British North America to the northeast formed the Dominion of Canada by uniting provinces between 1867 and 1873. The Dominion of Newfoundland to the east joined Canada in 1949.
