how did florida become part of the united states
Florida Territory The Territory of Florida was an organized incorporated territory of the United States that existed from March 30, 1822, until March 3, 1845, when it was admitted to the Union as the State of Florida. Originally the Spanish territory of La Florida, and later the provinces of East and West Florida, it was ceded to the United States as part of the 1819 Adams–Onís Treaty.[1] It was governed by the Florida Territorial Council.
Florida in the American Civil War Florida joined the Confederate States of America at the beginning of the Civil War, as the third of the original seven states to secede from the Union, following Lincoln's 1860 election. With the smallest population, nearly half of them slaves, Florida could only send 15,000 troops to the Confederate States Army. Its chief importance was in food-supply to the south, and support for blockade-runners, with its long coastline full of inlets that were hard to patrol.
