Florida was ceded to the United States by Spain in 1821. The Adams-Onis Treaty (also called the Transcontinental Treaty) had been signed in 1819, but the treaty took effect on this day in 1821. The United States agreed to give Spain $5 million and to renounce any claims on Texas in exchange for West Florida and East Florida. Children could learn more about Florida’s history at: Florida.
