The Treaty of Paris of 1898, 30 Stat. 1754, was an agreement made in 1898 that resulted in the Spanish Empire's surrendering control of Cuba and ceding Puerto Rico, parts of the Spanish West Indies, the island of Guam, and the Philippines to the United States. The cession of the Philippines involved a payment of $20 million from the United States to the Spanish Empire. The treaty was signed on December 10, 1898, and ended the Spanish-American War. The Treaty of Paris came into effect on April 11, 1899, when the documents of ratification were exchanged.
