In February 1920, the Philippine Senate and House of Representatives passed Act No. 2878, which abolished the Department of Mindanao and Sulu and transferred its responsibilities to the Bureau of Non-Christian Tribes under the Department of the Interior. Muslim dissatisfaction grew as power shifted to the Christianized Filipinos; it was one thing to be administered by the militarily superior Americans, another by their traditional enemies, the Christian Filipinos. Petitions were sent by Muslim leaders in 1921 and 1924 requesting that Mindanao and Sulu be administered directly by the United States. These petitions were not granted. Isolated cases of armed resistance were quickly crushed. In Cotabato, Datu Ambang of Kidapawan attempted to incite a jihad (holy war) against the Americans and the Christian Filipinos. This, however, did not take place when the governor of the province mobilized government forces.
