The Adams-Onis Treaty of 1819, also called Transcontinental Treaty, or Purchase of Florida, was not a direct outcome of a specific war or battle, but was significantly influenced by the aftermath of the War of 1812, which contributed to a climate of expansionism in the US.

In addition, Andrew Jackson's military actions against Seminole tribes in Spanish Florida during the First Seminole War, 1817 and 1818, highlighted Spain's inability to maintain order in the region.
