United States territorial acquisitions
West Florida was declared to be a U.S. possession in 1810 by President James Madison after the territory had declared its independence from Spain. Madison ordered the U.S. Army to take control. Six weeks later, the army entered and occupied the capital, St. Francisville, putting an end to the republic after 74 days of independence. Spain did not relinquish its claim to sovereignty (see West Florida Controversy) until ratification of the Adams–Onís Treaty. General Andrew Jackson personally accepted the delivery of West Florida from its Spanish governor on July 17, 1821.
Florida State University
In 1819 the Florida Territory was ceded to the United States by Spain as an element of the Adams–Onís Treaty. The Territory was conventionally split by the Appalachicola or later the Suwannee rivers into East and West areas. Florida State University is traceable to a plan set by the 1823 U.S. Congress to create a system of higher education. The 1838 Florida Constitution codified the basic system by providing for land allocated for the schools. In 1845 Florida became the 27th State of the United States, which permitted the resources and intent of the 1823 Congress regarding education in Florida to be implemented.
