The United States annexed the Philippines after the Spanish-American War in 1898 for several reasons:

1. Strategic Position: The Philippines is strategically located in the Pacific Ocean, making it an ideal location for projecting American military power and establishing naval bases in Asia.

2. Economic Interests: The Philippines was seen as a potential market for American goods and investments. The U.S. expected to gain economic benefits by exploiting the country's natural resources, such as timber, minerals, and agricultural products.

3. Spread of American Culture and Values: At that time, there was a belief in the United States that it had a moral duty to "civilize" and "uplift" non-Western societies. Annexing the Philippines was viewed as an opportunity to spread American values and institutions to the Filipino people.
