After the Spanish-American War, the United States established a colonial government in the Philippines. The United States introduced a number of reforms to the country, including a public school system, a healthcare system, and a transportation system. However, the United States also faced a number of challenges, including a nationalist movement and a communist insurgency.
In the 1930s, the United States began to prepare the Philippines for independence. The Tydings-McDuffie Act of 1934 set a timeline for Philippine independence, and the Philippine Commonwealth was established in 1935. The United States continued to assist the Philippines in its preparations for independence, and the country became fully independent in 1946.
The United States has continued to maintain strong relations with the Philippines since its independence. The two countries have a close economic relationship, and the United States is one of the largest sources of foreign investment in the Philippines. The United States also provides military assistance to the Philippines, and the two countries are allies in a number of regional security organizations.
