December 10, 1898 – The Treaty of Paris is signed, officially ending the conflict. The Treaty of Paris of 1898, 30 Stat. 1754, was an agreement made in 1898 that resulted in Spain surrendering control of Cuba, Puerto Rico, parts of the West Indies, Guam, and the Philippines to the United States in exchange for a payment of $20 million. It was signed on December 10, 1898, at the end of the Spanish-American War, and came into effect on April 11, 1899, when the ratifications were exchanged. The Treaty signaled the end of the Spanish Empire in America and the Pacific Ocean (see also the German–Spanish Treaty (1899)), and marked the beginning of an age of United States colonial power.
