The Spanish-American War of 1898 marked a significant turning point in the history of the United States. Sparked by the Cuban struggle for independence from Spain and heightened by the explosion of the USS Maine, this brief but impactful conflict reshaped the global balance of power and signaled the emergence of the U.S. as a world power.
Prelude to War: Cuban Struggle and Rising Tensions
For years, Cuba had been embroiled in a fierce struggle for independence from Spanish colonial rule. The conflict drew the attention of the United States due to Cuba’s proximity and the potential for economic and political instability in the region. By early 1898, tensions between the U.S. and Spain had reached a boiling point, exacerbated by sensationalist news reports—often referred to as “yellow journalism”—that inflamed public sentiment against Spain.
The situation escalated dramatically when the USS Maine, an American battleship, exploded in Havana Harbor on February 15, 1898. Although the cause of the explosion remains unclear, many Americans blamed Spain, leading to widespread outrage. In response, Congress passed a resolution supporting Cuban independence and authorized President McKinley to use military force if necessary.
The Outbreak of War: Major Battles and Key Victories

When Spain rejected U.S. demands, President McKinley ordered a naval blockade of Cuba and called for troops. The war officially began in late April 1898 and quickly expanded beyond Cuba, with significant battles taking place in the Philippines and Puerto Rico.
- Battle of Manila Bay (May 1, 1898): The first major engagement of the war occurred in Manila Bay, where Commodore George Dewey led the U.S. Navy to a decisive victory over the Spanish fleet. This battle gave the United States control of the Philippines and established Dewey as a national hero.
- Invasion of Cuba (June 1898): U.S. forces landed in Cuba and engaged in several fierce battles, including the Battle of San Juan Hill, where the Rough Riders, a volunteer cavalry unit led by Theodore Roosevelt, gained fame. Roosevelt’s leadership during this battle helped catapult him to national prominence.
- Battle of Santiago de Cuba (July 3, 1898): The war reached its climax when the U.S. Navy destroyed the Spanish fleet near Santiago de Cuba. This decisive victory effectively ended Spain’s naval power in the Caribbean, leading to the surrender of Santiago on July 17.
During the conflict, the United States also captured Puerto Rico and Guam, which would later become important U.S. territories.
The Treaty of Paris and the Aftermath
The fighting ended on August 12, 1898, with a ceasefire. The Treaty of Paris, signed in December 1898, formally ended the war and marked a significant shift in global power dynamics. Under the treaty’s terms, Spain relinquished its remaining colonies in the Caribbean and Pacific, ceding control of Cuba, Puerto Rico, Guam, and the Philippines to the United States.

The war had profound and long-lasting effects:
- Cuba gained independence, although the United States retained significant influence over the island, leading to a complex and often contentious relationship.
- Puerto Rico, Guam, and the Philippines became U.S. territories, sparking debates over American imperialism and the nation’s role as a colonial power.
- The Philippine-American War: In the Philippines, the end of Spanish rule led to new conflicts as many Filipinos sought full independence from the United States, resulting in the Philippine-American War, which lasted from 1899 to 1902.
The Role of Visual Media: Film Footage of the War

The Spanish-American War was one of the first conflicts to be captured on film, marking a significant milestone in the visual documentation of war. Between 1898 and 1901, film companies produced 68 short films that depicted various aspects of the war and its aftermath, including troops, naval battles, and key figures. These films provided a new dimension to war reporting, bringing the sights and sounds of conflict to audiences back home and paving the way for future documentary filmmaking.
