On this day in 1819, Spanish minister Do Luis de Onis and US Secretary of State John Quincy Adams, under the Monroe administration, sign the Florida Purchase Treaty in which Spain agrees to cede the remainder of its old province of Florida to the United States.
Spanish colonization of the Florida peninsula began at St. Augustine in 1565. The Spanish colonists enjoyed a brief period of relative stability before Florida came under attack from resentful Native Americans and ambitious English colonists to the north in the 17th century. Spain’s last-minute entry into the French and Indian War on the side of France cost it Florida, which the British acquired through the first Treaty of Paris in 1763. After 20 years of British rule, however, Florida was returned to Spain as part of the second Treaty of Paris, which ended the American Revolution in 1783.
Spain’s hold on Florida was tenuous in the years after American independence, and numerous boundary disputes developed with the United States. In 1819, after years of negotiations, the younger Adams achieved a diplomatic coup with signing above treaty, which officially put Florida into our national hands at no cost beyond the assumption of some $5 million of claims by US citizens against Spain. Formal U.S. occupation began in 1821, and General Andrew Jackson, hero of the War of 1812, was appointed governor. Florida was organized as a US territory in 1822 and was admitted into the Union as a slave state in 1845.
Today, Florida is distinctive for its large Cuban expatriate community and high population growth, as well as for its increasing environmental issues. The state’s economy relies mainly on tourism, agriculture, and transportation, which developed in the late 19th century. Florida is also world renowned for amusement parks, orange crops, winter vegetables, the Kennedy Space Center, and as a popular destination for retirees, plastic surgeons and gerontologists, personal trainers, fleeing felons and the flotsam and jetsam of humanity.
