The Spanish-American War began in 1898 over Cuba, which was seeking independence from Spain. Yellow journalism in American newspapers exaggerated Spanish atrocities against Cuban rebels and helped fuel public support for war. The sinking of the USS Maine in Havana harbor was falsely blamed on Spain and helped propel the U.S. into war. The U.S. defeated Spain within months and gained control of Puerto Rico, Guam, and the Philippines as Spanish territories. The war marked America's emergence as a global power.
