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.
West Florida
On October 27, 1810, U.S. President James Madison proclaimed that the United States should take possession of West Florida between the Mississippi and Perdido Rivers, based on a tenuous claim that it was part of the Louisiana Purchase. (See "The U.S. claim", below.) The West Florida government opposed annexation, preferring to negotiate terms to join the Union. Governor Fulwar Skipwith proclaimed that he and his men would "surround the Flag-Staff and die in its defense". William C. C. Claiborne was sent to take possession of the territory, entering the capital of St. Francisville with his forces on December 6, 1810, and Baton Rouge on December 10, 1810. Claiborne refused to recognize the legitimacy of the West Florida government, however, and Skipwith and the legislature eventually agreed to accept Madison's proclamation. Congress passed a joint resolution, approved January 15, 1811, to provide for the temporary occupation of the disputed territory and declaring that the territory should remain subject to future negotiation.
