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.
Territorial evolution of North America since 1763
Illinois Territory was split from Indiana Territory. Illinois Territory included present-day Illinois, northeastern Minnesota, and Wisconsin. Indiana Territory included the present-day borders of Indiana, with its western and eastern borders continuing northward; thus, it also included the central portion of the upper peninsula of Michigan, as well as Door Peninsula of present-day Wisconsin.
The short-lived Republic of West Florida declared its independence from Spain.
US President James Madison proclaimed the annexation of the Baton Rouge and Mobile Districts of West Florida, declaring them part of the Louisiana Purchase. The US Army occupied the capital, St. Francisville, on December 6 and Baton Rouge on December 10, bringing an end to the Republic of West Florida after 90 days.
