How did Spain cede control of Florida to the United States?

Spain ceded control of Florida to the United States through the Transcontinental Treaty of 1819. This treaty resolved territorial disputes between the two nations in North America. Spain relinquished its claims to Florida, which included both East and West Florida, in exchange for the United States recognizing Spanish sovereignty over Texas. The conflict known as the First Seminole War (1817-1818) also played a significant role, as U.S. military actions under General Andrew Jackson in Florida pressured Spain to finalize the cession. The treaty was ratified, officially transferring Florida to U.S. jurisdiction in 1821.1234
