History of Florida
In 1810, parts of West Florida were annexed by proclamation of President James Madison, who claimed the region as part of the Louisiana Purchase. These parts were incorporated into the newly formed Territory of Orleans. The U.S. annexed the Mobile District of West Florida to the Mississippi Territory in 1812. Spain continued to dispute the area, though the United States gradually increased the area it occupied.Seminole Indians based in East Florida had been raiding Georgia settlements, and runaway American slaves were their allies; Negro Fort, an abandoned British fortification in the far west of the territory, was manned by both Indians and blacks. The United States Army would lead increasingly frequent incursions into Spanish territory, including the 1817–1818 campaign against the Seminole Indians by Andrew Jackson that became known later as the First Seminole War. The United States now effectively controlled East Florida. Control was necessary, according to Secretary of State John Quincy Adams, because Florida had become "a derelict open to the occupancy of every enemy, civilized or savage, of the United States, and serving no other earthly purpose than as a post of annoyance to them." Florida had become a burden to Spain, which could not afford to send settlers or garrisons. Madrid therefore decided to cede the territory to the United States through the Adams–Onís Treaty, which took effect in 1821.
History of Hispanic and Latino Americans in the United States
The area of Spanish Florida diminished with the establishment of English colonies to the north and French colonies to the west. The English weakened Spanish power in the area by supplying their Creek Indian allies with firearms and urging them to raid the Timucuan and Apalachee client-tribes of the Spanish. The English attacked St. Augustine, burning the city and its cathedral to the ground several times, while the citizens hid behind the walls of the Castillo de San Marcos. The Spanish, meanwhile, encouraged slaves to flee the English-held Carolinas and come to Florida, where they were converted to Roman Catholicism and given freedom. They settled in a buffer community north of St. Augustine, called Gracia Real de Santa Teresa de Mose, the first completely black settlement in what would become the United States. Great Britain gained control of Florida diplomatically in 1763 through the Peace of Paris (the Castillo de San Marcos surrendered for the first time, having never been taken militarily). Britain tried to develop Florida through the importation of immigrants for labor, including some from Menorca and Greece, but this project ultimately failed. Spain regained Florida in the Treaty of Versailles (1783) after helping defeat Britain in the American Revolutionary War. Finally, in 1819, by terms of the Adams–Onís Treaty, Spain ceded Florida to the United States in exchange for the American renunciation of any claims on Texas. On March 3, 1845, Florida became the 27th state of the United States of America.
