[2][3] After the dissolution of the Republic of Zamboanga and others part of Mindanao are under US rule, the US civil government led by Governor William Howard Taft[citation needed] authorized the creation of the Moro Province that includes "all of the territory of the Philippines lying south of the eight parallel of latitude, excepting the island of Palawan and the eastern portion of the northwest peninsula of Mindanao.

Major General Leonard Wood, with the capacity of commander of the Army Department of Mindanao-Sulu was appointed governor of the province on August 6, 1903.

By 1913, Governor John J. Pershing agreed that the Moro Province needed to transition to civil government.

This was prompted by the Moros' personalistic approach to government, which was based on personal ties rather than a respect for an abstract office.

The province had its own Department of Public Instruction, separate from the education system that covered the rest of the Philippine Islands.

The head of the tribe has the power to sub-divide his wards and appoint deputies into these sub-wards with the approval of the district governor.
