The history of the Philippines from 1898 to 1946 began with the outbreak of the Spanish–American War in April 1898, when the Philippines was still a colony of the Spanish East Indies, and concluded when the United States formally recognized the independence of the Republic of the Philippines on July 4, 1946. With the signing of the Treaty of Paris on December 10, 1898, Spain ceded the Philippines to the United States. The interim U.S. military government of the Philippine Islands experienced a period of great political turbulence, characterized by the Philippine–American War.
