Anti-American spirit increased in Latin America when the United States intervened in the governments of Santo Domingo, Nicaragua, and Haiti.

After the Spanish-American War, the United States gained control of Cuba and Puerto Rico and developed economic interest in the Caribbean, During the Cold War, the United States actively tried to stop the spread of Communism in Central America and in Latin America. Those interventionist foreign policies in these regions have caused an increase in the anti-American spirit.
