Which amendment later gave the U.S. the right to intervene in Cuban affairs?

The amendment that later gave the United States the right to intervene in Cuban affairs was the Platt Amendment. Enacted in 1901 as part of the Army Appropriations Act, it defined the political relationship between the United States and Cuba after the Spanish-American War.

The amendment required Cuba to accept several conditions before the United States would end its military occupation. Most controversially, Cuba had to consent to a U.S. right to intervene to preserve Cuban independence and maintain a government capable of protecting life, property, and individual liberty. It also restricted Cuba’s foreign agreements and allowed the United States to lease land for naval bases, including Guantánamo Bay.

The Platt Amendment is often confused with the Teller Amendment. The Teller Amendment, adopted before the war in 1898, promised that the United States would not permanently annex Cuba. The Platt Amendment came later and sharply limited Cuban sovereignty. Its provisions shaped U.S.–Cuban relations until the 1930s, when the intervention clause was repealed, although the Guantánamo lease continued.
