The full acquisition of Florida by the United States was primarily achieved through the Adams-Onís Treaty of 1819, which was negotiated between Secretary of State John Quincy Adams and Spanish minister Luis de Onís. Tensions over border disputes, conflicts with Native American tribes, and American expansionist desires prompted Spain to cede Florida to the U.S. Additionally, Andrew Jackson's military incursions into Florida highlighted the difficulties Spain faced in controlling the territory, further compelling Spain to relinquish its claims. The treaty was ratified in 1821, formally transferring Florida to the United States.
