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.
History of Mississippi
Americans had continuing land disputes with the Spanish, even after taking control of much of this territory through the Louisiana Purchase (1803) from France. In 1810 the European-American settlers in parts of West Florida rebelled and declared their freedom from Spain. President James Madison declared that the region between the Mississippi and Perdido rivers, which included most of West Florida, had already become part of the United States under the terms of the Louisiana Purchase. The section of West Florida between the Pearl and Perdido rivers, known as the District of Mobile, was annexed to Mississippi Territory in 1812; Americans from the United States occupied Kiln, Mississippi, in 1813.
