Philippine–American War
In 1902, the United States Congress passed the Philippine Organic Act, which provided for the creation of the Philippine Assembly, with members to be elected by Filipino males. (Women did not have suffrage in the US or the Philippines.) This act was superseded by the 1916 Philippine Autonomy Act, which contained the first formal and official declaration of the United States government's commitment to eventually grant independence to the Philippines. The 1934 Philippine Independence Act created the Commonwealth of the Philippines the following year, a limited form of independence, and established a process ending in Philippine independence (originally scheduled for 1944, but interrupted and delayed by World War II). The United States granted independence in 1946, following World War II and the Japanese occupation of the Philippines, through the Treaty of Manila.
Balikatan
The U.S. acquired the Philippines after the Spanish–American War of 1898 and the subsequent Philippine–American War. The United States granted the Philippines independence in 1946. In 1951, the governments of the United States and the Philippines signed the Mutual Defense Treaty to "strengthen the fabric of peace" in the Pacific by agreeing to defend each other's territory in the case of external attack. In line with this treaty, the United States maintained until 1992 several military bases in the Philippines, including U.S. Naval Base Subic Bay and the Clark Air Base.
