EXPLANATIONS BELOW
Concept note-1: -Approved on May 22, 1903, the Platt Amendment was a treaty between the U.S. and Cuba that attempted to protect Cuba’s independence from foreign intervention. It permitted extensive U.S. involvement in Cuban international and domestic affairs for the enforcement of Cuban independence.
Concept note-2: -The Platt Amendment’s conditions prohibited the Cuban Government from entering into any international treaty that would compromise Cuban independence or allow foreign powers to use the island for military purposes.
Concept note-3: -The Platt Amendment came about as a result of the Spanish-American War, which occurred in 1898. During the roughly four months that the war lasted, the United States had a large military presence in Cuba, which it was ready to use to protect the US against Spanish attacks and protect US economic interests in Cuba.
Concept note-4: -In April 1898 Senator Henry M. Teller (Colorado) proposed an amendment to the U.S. declaration of war against Spain which proclaimed that the United States would not establish permanent control over Cuba.
Concept note-5: -Cubans opposed the provisions of the Platt Amendment. They claimed it gave far too much power to the United States and deprived Cubans of their independence.
