Which treaty (1819) ceded Florida to the United States and renounced Spain's claims to the Oregon Territory?

• A. Adams-Onis Treaty
• B. Treaty of Paris
• C. Gadsden Purchase
• D. Guadalupe Hidalgo

Answer: (A)

The main idea here is how treaties shape borders and control of territory. In 1819, the Adams-Onís Treaty between the United States and Spain accomplished two big things at once: Florida was ceded to the United States, and Spain gave up any claim to the Oregon Territory. The agreement also drew a clearer boundary line between U.S. and Spanish lands, from the Sabine River across to the Pacific, and it settled other issues like Texas claims by the U.S. relinquishing them. This combination—transferring Florida and renouncing Oregon—is specific to this treaty and is why it’s the correct choice. The other treaties come from different times and deal with different lands: the Treaty of Paris ended the American Revolution, the Gadsden Purchase added land from Mexico in the southwest, and Guadalupe Hidalgo ended the Mexican-American War, with different territorial outcomes.
