Platt Amendment
The 1901 Constitution, was Cuba's first as an independent state. It incorporated eight principles set out in the Platt Amendment without which United States troops would not have been withdrawn from Cuba, including the clause that the U.S. has the right to intervene in Cuba's affairs to protect its independence and guarantee the stability of its government. All but one of the Platt Amendment principles remained in force until a treaty between Cuba and the U.S., the Cuban–American Treaty of Relations (1934), negotiated as part of Franklin D. Roosevelt's Good Neighbor policy toward Latin America, took effect on 9 June 1934, leaving the U.S. only its right to a permanent lease to its Guantanamo Naval Station.
