United States occupation of Haiti

The United States occupation of Haiti began on July 28, 1915, when 330 U.S. Marines landed at Port-au-Prince, Haiti, after the National City Bank of New York (now Citibank) convinced U.S. President Woodrow Wilson to take control of the country's political and financial interests. The occupation took place following years of socioeconomic instability within Haiti that culminated with the lynching of Haitian President Vilbrun Guillaume Sam by a mob angered by his executions of political prisoners.
