The United States won the Spanish-American War. The U.S. victory ended the Spanish empire in the Western Hemisphere and enlarged the territory of the United States, giving it a territorial imperial foothold in the Caribbean and the Pacific Ocean.
Since 1895, Spanish forces and Cuban independence fighters had been struggling for control of Cuba. Though supportive of the rebels, the United States did not intervene until the mysterious 1898 explosion of the USS Maine in Havana. This incident pulled the United States into the war, which lasted 10 weeks and ended with the signing of the Treaty of Paris. In this treaty, Spain promised to cede Guam and Puerto Rico to the United States and to renounce all claims to Cuba, which would become an independent nation. Spain also transferred power in the Philippines to the United States for a sum of $20 million.
