Platt Amendment, an enactment of the U.S. Congress in 1901 defining relations with Cuba, then under United States occupation following the Spanish-American War. The amendment limited Cuba's independence and gave the United States the right to intervene to ensure stable government. Under pressure by the United States, the Cubans incorporated the amendment's provisions in their constitution of 1901. Cubans resented the amendment, and it was withdrawn in 1934. The amendment, attached to an army appropriations bill, was introduced by Senator Orville H. Platt (1827–1905) of Connecticut.
