Spanish–American War
Conflict that ended Spanish empire and launched U.S. overseas power.
In 1898, the United States and Spain went to war from late April to mid-August. The conflict was triggered by the explosion of the USS Maine in Cuba’s Havana Harbor. By the war’s end, the U.S. had taken control of Puerto Rico, Guam, and the Philippines, and turned Cuba into a protectorate. The fighting grew out of American involvement in Cuba’s fight for independence from Spain and the Philippine Revolution; the latter struggle later escalated into the Philippine–American War. The war ended nearly four centuries of Spanish rule in the Americas, Asia, and the Pacific. For the United States, it marked a rise to major world power status and brought a string of island territories across the globe, sparking fierce debate about whether expansionism was wise.
Spain’s empire had been in clear decline throughout the 1800s, while the United States had grown from a new nation into an emerging power. In 1895, Cuban nationalists revolted against Spanish rule, and the colonial authorities crushed the uprising brutally. According to scholar W. Joseph Campbell, American yellow journalism exaggerated the atrocities in Cuba to boost newspaper sales, swaying public opinion toward the rebels. Historian Andrea Pitzer, however, notes that Spanish military leadership genuinely turned more savage after the relatively conservative Governor-General Arsenio Martínez Campos was replaced by the aggressive Valeriano Weyler, nicknamed “The Butcher,” who adopted a harsh reconcentration policy. President Grover Cleveland resisted growing calls for U.S. intervention, and his successor William McKinley did the same. Although McKinley did not want war, he prepared for one.
In January 1898, the U.S. sent the armored cruiser USS Maine to Havana to protect American citizens. On February 15, the Maine sank after a mysterious explosion in the harbor. Political pressure then pushed McKinley to ask Congress for authority to use military force. On April 21, the U.S. began a blockade of Cuba, and soon both Spain and the United States declared war. Fighting took place in the Caribbean and the Pacific, where American war advocates had correctly predicted that U.S. naval power would be decisive. On May 1, a U.S. warship squadron destroyed the Spanish fleet at Manila Bay in the Philippines and captured the harbor. The first U.S. troops landed in southeastern Cuba on June 10, moved west, and fought the Battles of El Caney and San Juan Hill on July 1. They then destroyed the Spanish fleet and captured Santiago de Cuba on July 17. On June 20, Guam surrendered without a fight, and on July 25, U.S. forces landed on Puerto Rico, which had been blockaded since May 8. Fighting there continued until an armistice was signed on August 13.
The war officially ended with the Treaty of Paris, signed on December 10, 1898, on terms favorable to the United States. The treaty gave the U.S. ownership of Puerto Rico, Guam, and the Philippines, and set Cuba on a path to independence in 1902—though in practice it became a U.S. protectorate. The U.S. paid Spain $20 million (about $770 million today) for infrastructure Spain had built in the Philippines. In Spain, the defeat shocked the national psyche and sparked a deep philosophical and artistic reevaluation of Spanish society, known as the Generation of '98.
Spain’s attitude toward its colonies had been shaped by the Peninsular War, the loss of most American colonies in the early 1800s, and three Carlist Wars. Liberal Spanish leaders like Antonio Cánovas del Castillo and Emilio Castelar redefined the idea of empire to fit a growing Spanish nationalism. In an 1882 speech at the University of Madrid, Cánovas described the Spanish nation as united by shared culture and language on both sides of the Atlantic. He viewed Spanish colonialism as more “benevolent” than that of other European powers. Before the war, many in Spain believed that spreading civilization and Christianity was the empire’s main purpose. Cuba, Spanish for nearly four hundred years, was seen as an integral part of the nation. This focus on preserving the empire would later damage Spain’s national pride after the war.
American interest in the Caribbean dated back to the Monroe Doctrine of 1823, which declared that the U.S. would not allow European powers to retake or expand their colonies in the Americas, though it would respect existing ones. Before the Civil War, Southern interests tried to buy Cuba and turn it into a slave state, proposing the Ostend Manifesto in 1854, but anti-slavery forces blocked it. After the Civil War and Cuba’s Ten Years’ War, U.S. businesses began dominating Cuba’s sugar market. By 1894, 90% of Cuba’s exports went to the United States, which also supplied 40% of Cuba’s imports. Cuba’s exports to the U.S. were nearly twelve times greater than those to Spain. American business interests noted that while Spain still held political authority over Cuba, the United States held the real economic power.

Lore & Background
The 19th century represented a clear decline for the Spanish Empire, while the United States went from a newly founded country to a rising power. In 1895, Cuban nationalists began a revolt against Spanish rule, which was brutally suppressed by the colonial authorities. W. Joseph Campbell argues that yellow journalism in the U.S. exaggerated the atrocities in Cuba to sell more newspapers and magazines, which swayed American public opinion in support of the rebels. But historian Andrea Pitzer also points to the actual shift toward savagery of the Spanish military leadership, who adopted the brutal reconcentration policy after replacing the relatively conservative Governor-General of Cuba Arsenio Martínez Campos with the more unscrupulous and aggressive Valeriano Weyler, nicknamed 'The Butcher.' President Grover Cleveland resisted mounting demands for U.S. intervention, as did his successor William McKinley. Though not seeking a war, McKinley made preparations in readiness for one. In January 1898, the U.S. Navy armored cruiser USS Maine was sent to Havana to provide protection for U.S. citizens. After the Maine was sunk by a mysterious explosion in the harbor on February 15, 1898, political pressures pushed McKinley to receive congressional authority to use military force. On April 21, the U.S. began a blockade of Cuba, and soon after Spain and the U.S. declared war. The war was fought in both the Caribbean and the Pacific, where American war advocates correctly anticipated that U.S. naval power would prove decisive. On May 1, a squadron of U.S. warships destroyed the Spanish fleet at Manila Bay in the Philippines and captured the harbor. The first U.S. forces landed in Cuba on June 10 in the island's southeast, moving west and engaging in the Battles of El Caney and San Juan Hill on July 1 and then destroying the Spanish fleet and capturing Santiago de Cuba on July 17. On June 20, the island of Guam surrendered without resistance, and on July 25, U.S. troops landed on Puerto Rico, of which a blockade had begun on May 8 and where fighting continued until an armistice was signed on August 13. The war formally ended with the 1898 Treaty of Paris, signed on December 10 with terms favorable to the U.S. The treaty ceded ownership of Puerto Rico, Guam, and the Philippines to the U.S., and set Cuba up to become an independent state in 1902, although in practice it became a U.S. protectorate. The cession of the Philippines involved payment of $20 million ($770 million today) to Spain by the U.S. to cover infrastructure owned by Spain. In Spain, the defeat in the war was a profound shock to the national psyche and provoked a thorough philosophical and artistic reevaluation of Spanish society known as the Generation of '98.
Reader's Guide
The combined problems arising from the Peninsular War (1807–1814), the loss of most of its colonies in the Americas in the early 19th-century Spanish American wars of independence, and three Carlist Wars (1832–1876) marked a low point for Spanish colonialism. Liberal Spanish elites like Antonio Cánovas del Castillo and Emilio Castelar offered new interpretations of the concept of 'empire' to dovetail with the emerging Spanish nationalism. Cánovas made clear in an address to the University of Madrid in 1882 his view of the Spanish nation as based on shared cultural and linguistic elements—on both sides of the Atlantic—that tied Spain's territories together. Cánovas saw Spanish colonialism as more 'benevolent' than that of other European colonial powers. The prevalent opinion in Spain before the war regarded the spreading of 'civilization' and Christianity as Spain's main objective and contribution to the New World. The concept of cultural unity bestowed special significance on Cuba, which had been Spanish for almost four hundred years, and was viewed as an integral part of the Spanish nation. The focus on preserving the empire would have negative consequences for Spain's national pride in the aftermath of the Spanish–American War. In 1823, the fifth American President James Monroe (1758–1831, served 1817–25) enunciated the Monroe Doctrine, which stated that the United States would not tolerate further efforts by European governments to retake or expand their colonial holdings in the Americas or to interfere with the newly independent states in the hemisphere. The U.S. would, however, respect the status of the existing European colonies. Before the American Civil War (1861–1865), Southern interests attempted to have the United States purchase Cuba and convert it into a new slave state. The pro-slavery element proposed the Ostend Manifesto of 1854. Anti-slavery forces rejected it. After the American Civil War and Cuba's Ten Years' War, U.S. businessmen began monopolizing the devalued sugar markets in Cuba. In 1894, 90% of Cuba's total exports went to the United States, which also provided 40% of Cuba's imports. Cuba's total exports to the U.S. were almost twelve times larger than the export to Spain. U.S. business interests indicated that while Spain still held political authority over Cuba, it was the U.S. that held economic power over Cuba.
