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.
Cuban Americans
Before the Louisiana Purchase and the Adams–Onís Treaty of 1819, Spanish Florida, and when divided during British occupation, East Florida and West Florida, including what is now Florida and the Gulf Coast west to the Mississippi River were provinces of the Captaincy General of Cuba (Captain General being the Spanish title equivalent to the British colonial Governor). Consequently, Cuban immigration to the U.S. has a long history, beginning in the Spanish colonial period in 1565 when St. Augustine, Florida was established by Pedro Menéndez de Avilés, and hundreds of Spanish-Cuban soldiers and their families moved from Cuba to St. Augustine to establish a new life.
