The treaty signed in 1898, ending the Spanish-American War, is the Treaty of Paris. This treaty formally concluded the conflict between the United States and Spain, which arose from U.S. interventions in Cuba's struggle for independence. As a result of the treaty, Spain relinquished control over its territories in the Caribbean, including Cuba, and ceded Guam and Puerto Rico to the U.S. Additionally, the Philippines were transferred to the U.S. for $20 million. This treaty marked a significant shift in U.S. foreign policy, signaling its emergence as a global power and paving the way for further expansion into Asia and the Pacific.
