What did Spain and the us agree to with the Adams-Onis treaty?

The Adams-Onís Treaty, signed in 1819, was an agreement between Spain and the United States that resolved territorial disputes between the two nations. Spain ceded Florida to the U.S. and defined the boundary between U.S. territory and New Spain (now Mexico). In return, the U.S. agreed to assume about $5 million in claims by American citizens against Spain. This treaty also affirmed the U.S. claim to the Oregon Territory, further establishing its influence in North America.
