The province was divided into five districts, with American officers serving as district governors and deputy governors. These districts included: Cotabato, Davao, Lanao, Sulu, and Zamboanga. The districts were sub-divided into tribal wards, with major datus serving as ward chiefs and minor datus serving as deputies, judges, and sheriffs. This system took advantage of the existing structure of Moro political society, which was based on personal ties while paving the way for a more individualistic society, where the office, not the person holding it, would be given respect.
