What treaty ended the Spanish-American War?

The treaty that ended the Spanish-American War was the Treaty of Paris of 1898.

Spain and the United States signed the treaty in Paris on December 10, 1898, after an August armistice had stopped active fighting. It formally ended the conflict and required Spain to relinquish sovereignty over Cuba, Puerto Rico, and Guam. Spain also ceded the Philippines to the United States in exchange for a payment of $20 million.

The treaty marked the collapse of much of Spain's remaining overseas empire and the emergence of the United States as a major world power. It took effect on April 11, 1899, when the two countries exchanged their ratifications. The U.S. Senate approved it by a narrow margin after a contentious debate over American imperialism.

The treaty did not make Cuba a U.S. possession. Instead, Spain gave up its claim to the island, which remained under U.S. military occupation until Cuban independence in 1902. The Treaty of Ghent ended the War of 1812, while the Treaty of Versailles ended World War I.
