April 25th 1898: Spanish-American War begins
On this day in 1898, the United States of America declared war on Spain, thus beginning the Spanish-American War. The war was a result of American intervention in the Cuban War of Independence as Cuba revolted against Spanish rule. Political pressure to end the Spanish atrocities and to avenge the sinking of a US ship forced President McKinley into war. The war was over within the year. Cuban independence was secured, and the US had temporary control of Cuba and authority over Puerto Rico, Guam and the Philippines.
