Long-Term Causes: Political and Economic Factors
- By the late 19th century, Spain’s colonial empire was in decline, but it still controlled Cuba and the Philippines, two regions of high strategic and economic value.
- The U.S. had significant economic investments in Cuba, particularly in sugar plantations and trade, making stability in the island vital to American business interests.
- Cuban nationalists had been fighting for independence since the Ten Years’ War (1868–1878), inspiring sympathy in the U.S. and drawing comparisons to America’s own revolutionary past.
- U.S. policymakers increasingly believed that the removal of Spain from the hemisphere aligned with the Monroe Doctrine’s vision of excluding European powers from the Americas.
Monroe Doctrine
A U.S. policy (1823) declaring the Western Hemisphere off-limits to further European colonization or interference.
Immediate Causes: Public Pressure and Media Influence
- In the 1890s, yellow journalism (sensationalized reporting by newspapers owned by William Randolph Hearst and Joseph Pulitzer) exaggerated Spanish atrocities in Cuba, fueling public outrage.
- The publication of the De Lôme Letter (1898), in which a Spanish diplomat insulted President William McKinley, further inflamed American nationalism.
- The explosion of the USS Maine in Havana Harbor on February 15, 1898, killing 266 sailors, was blamed on Spain (despite unclear evidence), becoming the final spark for war.
- The rallying cry “Remember the Maine!” united the public behind military action.
The Road to War : Cuba’s Struggle for Independence
- Cuban rebels, led by José Martí, launched a renewed war of independence in 1895 against Spanish rule, which responded with brutal counter insurgency tactics.
- Spanish General Valeriano Weyler introduced reconcentration camps, forcing civilians into guarded zones to cut off rebel support, resulting in widespread famine and disease.
- American media portrayed Weyler as the “Butcher of Cuba,” amplifying calls for U.S. humanitarian intervention.
- U.S. business interests, facing economic disruption from the conflict, pressured Washington to act.
- These events combined moral sympathy, strategic calculation, and media sensationalism into a powerful justification for war.
The War Itself: Modernization and Expansion
- The U.S. declared war on Spain on April 25, 1898, vowing to liberate Cuba but also eyeing broader imperial opportunities.
- The conflict demonstrated the impact of modernization: industrial capacity, steam-powered fleets, and telegraph communication allowed rapid mobilization.
- Admiral George Dewey’s victory at Manila Bay (Philippines) on May 1, 1898, destroyed the Spanish Pacific fleet in a single morning, showcasing American naval dominance.
- In the Caribbean, U.S. troops, including the Rough Riders, a volunteer cavalry led by Theodore Roosevelt, captured San Juan Hill and Santiago de Cuba.
- By August, Spain requested peace; the Treaty of Paris (1898) formally ended the war.

The Philippines and the Global Impact of the War
- The U.S. victory in the Philippines revealed its new global ambitions.
- President McKinley justified annexation by claiming it was America’s duty to “civilize and Christianize” the islands, despite the fact that most Filipinos were already Catholic.
- Filipino nationalists, led by Emilio Aguinaldo, initially supported the U.S. against Spain but later resisted American occupation in the Philippine–American War (1899–1902).
- This brutal conflict, which killed over 200,000 Filipinos, exposed contradictions between American democratic ideals and imperial practice.
- The annexation established the U.S. as a Pacific power, extending influence toward China and Southeast Asia, and marked the beginning of American overseas imperialism.
Effects: Political, Economic, and Ideological Consequences
- Politically, the war signaled the United States’ arrival as a world power; it gained overseas territories and naval bases from the Caribbean to the Pacific.
- Economically, the U.S. gained access to new markets and resources, particularly in Asia, setting the stage for Dollar Diplomacy and expansion of trade.
- Socially and ideologically, the war fostered both national pride and anti-imperialist backlash. Figures like Mark Twain and Andrew Carnegie condemned annexation as a betrayal of democratic principles.
- The war also inspired Latin American anxiety about growing U.S. dominance, influencing regional diplomacy in the early 20th century.
Legacy
- The Spanish–American War was a short conflict with long-lasting consequences: it ushered in a new era of American global engagement, military modernization, and imperial competition.
- It transformed the U.S. into a transoceanic power, with territories in both hemispheres, while exposing internal tensions between expansion and democracy.
- The war also reshaped inter-American relations, marking the U.S.’s shift from “protector” to regional hegemon.
- Emphasize the multi-causal nature of the war by combining humanitarian, economic, and ideological motives.
- Highlight how modernization (navy, communication, industrial capacity) turned expansionist theory into action.
- Use Cuba and the Philippines as comparative examples of liberation vs. imperialism.
- Treating the war solely as U.S. aggression without mentioning Cuban agency.
- Ignoring the domestic ideological divide between imperialists and anti-imperialists.
- To what extent was the Spanish–American War (1898) caused by economic rather than ideological factors?
- Assess the impact of the Spanish–American War on U.S. foreign policy and international standing.
- Examine how modernization influenced the conduct and outcomes of the Spanish–American War.
