The Spanish-American War was an 1898 conflict between the United States and Spain that ended Spanish colonial rule in the Americas and resulted in U.S. acquisition of territories in the western Pacific and Latin America. The war originated in the Cuban struggle for independence from Spain, which began in February 1895.
The Treaty of Paris ending the Spanish-American War was signed on December 10, 1898. In it, Spain renounced all claim to Cuba, ceded Guam and Puerto Rico to the United States and transferred sovereignty over the Philippines to the United States for $20 million. Puerto Rico had been granted autonomy from Spain in 1897.
