The Caribbean between Europe and the United States

From the Spanish-American War and occupations to the Panama Canal, World War II and the Cuban Missile Crisis

From European empires to American strategic power

For centuries the great external powers of the Caribbean were European. During the nineteenth century another power moved steadily into the region. By the beginning of the twentieth century the United States had become the dominant strategic force in much of the Caribbean.

Cuba and the Spanish-American War

Cuba’s location near Florida and the entrance to the Gulf of Mexico made it strategically important to the United States. American investment in Cuban sugar and trade grew during the nineteenth century. When Cuba’s independence war resumed in 1895, Spanish reconcentration policies caused enormous suffering and intensified American hostility.

The explosion of USS Maine in Havana harbour in February 1898 accelerated intervention. The precise cause remains debated, but the political result was immediate. The United States went to war with Spain. Spain was defeated and ceded Puerto Rico, Guam and the Philippines while relinquishing Cuba.

Cuba: independent, but constrained

Cuba did not become a conventional American colony. Formal independence came in 1902. Yet the Platt Amendment allowed extensive American intervention and provided the basis for the lease of Guantánamo Bay. Cuba had escaped Spanish colonial rule without escaping external strategic pressure.

The Roosevelt Corollary and financial control

The Monroe Doctrine had warned European powers against new colonial intervention in the Americas. Theodore Roosevelt’s 1904 corollary went further, claiming an American right to intervene when instability or debt might invite European action.

The Dominican Republic became an important example. The United States took control of customs revenues in 1905 to ensure payment of foreign debts. Military occupation followed from 1916 to 1924.

Haiti 1915–1934

American Marines occupied Haiti after political crisis in 1915 and remained until 1934. The occupation reorganized finance and infrastructure but also imposed foreign control, used coercive labour practices and provoked armed resistance. It embodied a recurring contradiction: Washington could point to roads and administration; Haitians could point to the loss of sovereignty.

The Panama Canal changes the strategic map

The opening of the Panama Canal in 1914 transformed Caribbean strategy. Protecting the Atlantic approaches became a major American objective. Caribbean bases gained importance because ships moving between oceans now passed through a narrow artificial route.

Puerto Rico and the US Virgin Islands

Puerto Rico was ceded directly to the United States in 1898. Puerto Ricans became US citizens in 1917, and the island later developed its present Commonwealth status. Residents are US citizens but do not possess the same federal voting representation as residents of states.

In 1917 the United States purchased the Danish West Indies from Denmark for twenty-five million dollars in gold. They became the US Virgin Islands. The transfer showed that Caribbean sovereignty could still be negotiated between distant governments well into the twentieth century.

World War II reaches the Caribbean

German U-boats attacked Allied shipping around Aruba, Curaçao, Trinidad and other areas. Oil tankers and refineries became major strategic targets. The Destroyers for Bases Agreement of 1940 also expanded American military presence in British Caribbean territories.

Cuba and the Cold War

The Cuban Revolution of 1959 turned the Caribbean into a central Cold War theatre. Castro’s government nationalized American property and aligned increasingly with the Soviet Union. In 1961 the CIA-backed Bay of Pigs invasion failed.

In 1962 the Soviet Union secretly installed nuclear missiles in Cuba. American reconnaissance discovered them. President John F. Kennedy imposed a naval quarantine. For thirteen days the United States and Soviet Union approached the possibility of nuclear war.

Why 1962 was different: earlier Caribbean conflicts were fought over ports, shipping and territory. The missile crisis made the same geography relevant to nuclear weapons that could reach their targets in minutes.

The Dominican Republic and Grenada

In 1965 the United States intervened in the Dominican Republic during a civil conflict, arguing that it needed to protect lives and prevent a communist takeover. In 1983 US forces invaded Grenada after the internal collapse of Maurice Bishop’s revolutionary government.

Supporters of these interventions emphasized security and political stability. Critics saw a pattern in which Caribbean sovereignty remained conditional when American strategic interests were threatened.

Europe never disappeared

France remains sovereign in Martinique, Guadeloupe, Saint Martin and Saint Barthélemy. The Netherlands remains constitutionally connected to Aruba, Curaçao, Sint Maarten, Bonaire, Sint Eustatius and Saba. Britain retains several overseas territories. The United States governs Puerto Rico and the US Virgin Islands.

The geography beneath every technology

Galleons gave way to battleships, then aircraft carriers and missiles. Fortresses gave way to airfields and surveillance systems. The technology changed repeatedly, but the geography did not. The Caribbean lies between North and South America, beside the Gulf of Mexico and the Panama Canal.

The region did not choose this geography. History repeatedly made it pay for it.
