The Adams -- Onís Treaty, also known as the Transcontinental Treaty, was signed on February 22, 1819, by John Quincy Adams and Luis de Onís y González-Vara, but did not take effect until after it was ratified by Spain on October 24, 1820, and by the United States on February 19, 1821. The U.S. received Florida under Article 2 and inherited Spanish claims to the Oregon Territory under Article 3, while ceding all its claims on Texas to Spain under Article 3 (with the independence of Mexico in 1821, Spanish Texas became Mexican territory), and pledged to indemnify up to $5,000,000 in claims by American citizens against Spain under Article 11. Under Article 15, Spanish goods received exclusive most favorable nation tariff privileges in the ports at Pensacola and St. Augustine for twelve years.
