The Platt Amendment was United States legislation enacted as part of the Army Appropriations Act of 1901 that defined the relationship between the United States and Cuba following the Spanish–American War. It stipulated seven conditions for the withdrawal of United States troops remaining in Cuba at the end of the Spanish–American War, and an eighth condition that Cuba sign a treaty accepting these seven conditions. It helped to define the terms of Cuba–United States relations.
On June 12, 1901, the Cuban Constitutional Assembly approved the Platt Amendment, which had been proposed by the United States of America. The document came with a withdrawal of U.S troops from Cuba after the Spanish-American War. It amended its constitution to contain, word for word, the seven applicable demands of the Platt Amendment.
