Which treaty ceded Florida from Spain to the United States?

• A. Adams Onis Treaty
• B. Treaty of Paris
• C. Gadsden Purchase
• D. Louisiana Purchase

Answer: (A)

The transfer of Florida from Spain to the United States was accomplished with the Adams-Onís Treaty, also known as the Transcontinental Treaty. Signed in 1819 and ratified in 1821, it ceded Florida to the United States and, in return, the U.S. gave up its claims to Texas and agreed on a defined boundary between U.S. and Spanish territories in the West. This treaty also solidified Florida’s status as a U.S. territory, later becoming a state. The other options don’t involve Florida: the Treaty of Paris ended the American Revolution; the Gadsden Purchase dealt with land in present-day southern Arizona and New Mexico; the Louisiana Purchase expanded U.S. territory from France but did not involve Florida.
