Under the Platt Amendment, Cuba was declared a US protectorate.

The Platt Amendment was passed in 1901 by the United States Congress. It provided the conditions for the withdrawal of American troops from Cuba since the Spanish-American War of 1898. Included in the Cuban Constitution, this amendment defined American-Cuban relations and formalized the right of US interference in the Republic of Cuba. It remained valid until the Treaty of Relations of 1934.
