The Treaty of Paris of 1898 ended the Spanish-American War on Dec. 10, 1898. The treaty required the Spanish Empire to relinquish control of Puerto Rico, Guam and Cuba to the United States and the U.S. to pay Spain $20 million in exchange for the Philippines.
Prior to 1898, Cubans attempted several revolts against the Spanish Empire, but each was unsuccessful. The general population of the United States supported Cuban freedom from European rule and was further enticed by increasing U.S. economic interests abroad. The Philippines were also getting restless, so the U.S. pitted its military against Spain. A surprising victory for U.S. Admiral George Dewey in Manila marked the turning point in the war, leading to the beginning of negotiations in Paris on Oct. 1, 1898.
