Why did the U.S. acquired Florida?

The U.S. acquired Florida primarily through the Adams-Onís Treaty of 1819, where Spain ceded Florida to the United States. This acquisition was motivated by the desire to eliminate Spanish influence in North America, enhance territorial security, and curb the activities of runaway slaves and Native American tribes in the region. The treaty was also influenced by U.S. military actions, particularly Andrew Jackson's incursions into Florida. Ultimately, the acquisition reflected America's broader expansionist goals during that period.
