Philippine resistance against Japan
During the Japanese occupation of the islands in World War II, there was an extensive Philippine resistance movement (Filipino: Kilusan ng Paglaban sa Pilipinas), which opposed the Japanese and their collaborators with active underground and guerrilla activity that increased over the years. Fighting the guerrillas – apart from the Japanese regular forces – were a Japanese-formed Bureau of Constabulary (later taking the name of the old Philippine Constabulary during the Second Republic),[12][13] the Kenpeitai (the Japanese military police),[12] and the Makapili (Filipinos fighting for the Japanese).[14] Postwar studies estimate that around 260,000 people were organized under guerrilla groups and that members of anti-Japanese underground organizations were more numerous.[15][16] Such was their effectiveness that by the end of World War II, Japan controlled only twelve of the forty-eight provinces.
Select units of the resistance would go on to be reorganized and equipped as units of the Philippine Army and Constabulary.[17] The United States Government officially granted payments and benefits to various ethnicities who have fought with the Allies by the war's end. However, only the Filipinos were excluded from such benefits, and since then these veterans have made efforts in finally being acknowledged by the United States. Some 277 separate guerrilla units made up of 260,715 individuals were officially recognized as having fought in the resistance movement.[18]
