List of colonial governors of Florida
The colonial governors of Florida governed Florida during its colonial period (before 1821). The first European known to arrive there was Juan Ponce de León in 1513, but the governorship did not begin until 1565, when Pedro Menéndez de Avilés founded St. Augustine and was declared Governor and "Adelantado" of Florida. This district was subordinated to the Viceroyalty of New Spain. In 1763, following the transfer of Florida to Britain, the territory was divided into West Florida and East Florida, with separate governors. This division was maintained when Spain resumed control of Florida in 1783, and continued as provincial divisions with the Spanish Constitution of 1812. The Spanish transferred control of Florida to the United States in 1821, and the organized, incorporated Florida Territory was established on March 30, 1822. This became the modern State of Florida on March 3, 1845.
Treaty of Moultrie Creek
The indigenous peoples of Florida had largely died out by early in the 18th century, and various groups and bands of Muskogean-speakers (commonly called "Creek Indians") and other groups such as Yamasee and Yuchi moved into the area, often with the encouragement of the Spanish colonial government. These groups, which often lived on both sides of the border between Florida and Georgia, came into increasing conflict with white settlers after the United States became independent. When the United States acquired Florida from Spain in 1821 (by means of the Adams-Onís Treaty), the conflict increased. In 1823, the United States government decided to settle the Seminoles on a reservation in the central part of the territory.
