What was the impact of the platt amendment?

The so-called Platt Amendment was a legal provision, inserted in the Constitutional Charter of Cuba, which authorized the United States to intervene in that country at any time when reciprocal interests of both countries were threatened. Thus, in practice, Cuba became an American protectorate.

When Cuba became formally independent on May 20, 1902, as a result of the Spanish-American War, it had to comply with the Platt Amendment, which allowed the United States to intervene in internal affairs of Cuba. Moreover, the Amendment allowed the United States to maintain a base in Guantanamo Bay, Cuba, still in American hands today.

The Platt Amendment represented an interference in Cuban affairs, restricting the sovereign exercise of Cuba's foreign and commercial policy.
