When did the United States intervene militarily in the Dominican Republic?

The United States intervened militarily in the Dominican Republic during two primary periods in the 20th century:

• 1916–1924: Following the collapse of the nation's political structure, the United States assumed control of the government. During this occupation, the U.S. Marine Corps managed infrastructure projects, enacted legal reforms favoring U.S. business interests, and established a unified military constabulary.123
• 1965–1966: This second period of military intervention occurred during a time of significant political and civil disorder within the country.1

These interventions reflect a broader history of U.S. involvement in the internal affairs of nations across the Caribbean and Latin America, often driven by strategic interests and regional stability concerns.41
