Introduction

The Spanish-American War was a brief but significant conflict fought in 1898 between Spain and the United States. Triggered by Cuba’s fight for independence, the sinking of the USS *Maine*, and sensationalized media, the war lasted about ten weeks and involved battles in both the Caribbean and the Pacific. It marked a turning point by signaling the decline of Spanish colonial power and the rise of the United States as a global force. The war ended with the Treaty of Paris, where Spain relinquished control of Cuba, Puerto Rico, Guam, and sold the Philippines to the U.S., reshaping international power dynamics[^1^][^4^].

Background and causes of the Spanish-American War

In the late 19th century, Cuba was struggling to gain independence from Spanish colonial rule, which began a rebellion in February 1895. Spanish efforts to suppress the revolt involved harsh measures, including forcing Cubans into poorly supplied reconcentration camps, causing widespread suffering and death. American newspapers in the U.S. exaggerated Spanish atrocities through sensational reporting known as yellow journalism, inflaming public opinion and sympathy for the Cuban cause. The sinking of the USS Maine in Havana Harbor on February 15, 1898, which killed 266 American sailors, heightened tensions. Although the cause of the explosion was unclear, many Americans blamed Spain. Economic interests suffered as trade with Cuba was disrupted, adding to calls for intervention. These factors combined to push the United States toward war, culminating in the declaration of war against Spain in April 1898, motivated by both humanitarian concerns and strategic interests.

Key events of the Spanish-American War

The Spanish-American War unfolded rapidly through a series of decisive battles and naval actions between April and August 1898.

Major naval clashes

The war began with the Battle of Manila Bay on May 1, 1898, when Commodore George Dewey led the U.S. Asiatic Squadron against the Spanish Pacific fleet near the Philippines. Dewey’s forces destroyed the Spanish ships with little American loss, securing control over Manila Bay early in the conflict. Meanwhile, in the Caribbean, the U.S. Navy blockaded and bombarded Spanish positions, notably at Santiago de Cuba, where on July 3, 1898, the Spanish fleet under Admiral Cervera attempted to break out but was annihilated by the U.S. fleet. These naval victories were pivotal in gaining the upper hand and crippling Spain’s ability to reinforce or resupply its forces overseas.

Land battles in Cuba and Puerto Rico

On land, the Battle of San Juan Hill on July 1, 1898, was a key turning point. American troops, including the Rough Riders led by Theodore Roosevelt, engaged Spanish forces on the San Juan Heights. This battle helped lift the siege of Santiago, as the U.S. army pressed Spanish troops into retreat. Following this, Santiago’s garrison surrendered on July 17, marking a significant victory in Cuba. Shortly afterward, U.S. forces launched an invasion of Puerto Rico, beginning on July 25. American troops met minimal resistance and quickly advanced inland, capturing key towns including Mayaguez by mid-August.

End of hostilities and occupation

By mid-August, major fighting was over. American forces occupied Manila with minor conflict by August 13, and a peace protocol was signed on August 12, signaling the end of active hostilities. Spanish troops surrendered key positions in both Cuba and the Philippines. The victory negotiations soon followed, but fighting itself was largely concluded within three months. The war was notable for its swift pace, with key battles and naval engagements occurring within a brief span of weeks, effectively shifting control from Spain to the United States across several territories.

During the conflict, the United States combined naval supremacy with coordinated land assaults to defeat Spanish forces rapidly in both the Caribbean and the Pacific theaters, marking the core course of the Spanish-American War.

Outcomes and effects of the conflict

The Spanish-American War had major outcomes that reshaped the world. Most notably, it ended Spain’s colonial rule in the Americas, forcing Spain to turn inward and renew itself culturally and economically. The United States emerged as a global power, gaining control of key territories such as Puerto Rico, the Philippines, Guam, and temporary control over Cuba. Cuba became an independent republic in 1902, although the U.S. maintained the right to intervene under the Platt Amendment, which many Cubans saw as a limitation on their sovereignty.

The war also paved the way for the construction of the Panama Canal, which opened in 1914, linking the Atlantic and Pacific oceans to facilitate global trade. Additionally, the conflict boosted the reputation of Theodore Roosevelt, who led the Rough Riders, helping him rise to the presidency. The treaty that ended the war sparked the Philippine-American War, a violent conflict marking the challenges of U.S. imperialism.

Historical importance and legacy

The Spanish-American War marked the end of almost four centuries of Spanish rule in the Americas, Asia, and the Pacific, dramatically shifting global power. It resulted in the United States acquiring Puerto Rico, Guam, and the Philippines, and establishing a protectorate over Cuba. This war propelled the U.S. into the status of a major imperial power and changed how it engaged in foreign policy, setting trends that lasted into the 20th century. The conflict also introduced the U.S. as a significant military force on the world stage, signaling its arrival as a global power.
