Final answer:
The conflict between the U.S. and Filipino forces led by Emilio Aguinaldo after the Spanish-American War is known as the Philippine-American War. It was a result of the U.S. refusal to recognize Filipino independence, leading to a protracted and deadly guerilla conflict, ending with U.S. control until Philippine independence in 1946.
Step-by-step explanation:
The conflict between the United States and the Philippines after the Spanish-American War was marked by the staunch resistance of Filipinos under the leadership of Emilio Aguinaldo. Despite an initial collaboration with U.S. forces to defeat the Spanish, tensions escalated when the U.S. refused to recognize the independence of the Philippines, which had been declared by Aguinaldo. The conflict, known as the Philippine-American War, was a brutal guerilla war lasting from 1899 to 1902 and resulted in high casualties and significant resistance against U.S. colonization efforts. Eventually, the U.S. established control over the Philippines, with Aguinaldo's capture in 1901, and continued to modernize the nation until its independence in 1946.
