The Teller Amendment to the U.S. declaration of war against Spain in 1898 disavowed any intention of exercising "sovereignty, jurisdiction or control" over Cuba, but the United States only agreed to withdraw its troops from Cuba when Cuba agreed to the eight provisions of the Platt Amendment, an amendment to the 1901 Army Appropriations Act authored by Connecticut Republican Senator Orville H. Platt, which would allow the United States to intervene in Cuban affairs if needed for the maintenance of good government and committed Cuba to lease to the U.S. land for naval bases. Cuba leased to the United States the southern portion of Guantánamo Bay, where a United States Naval Station had been established in 1898. The Platt Amendment defined the terms of Cuban-U.S. relations for the following 33 years and provided the legal basis for U.S. military interventions with varying degrees of support from Cuban governments and political parties.
