In addition, under this treaty the Sultan and his datus (tribal chiefs) were to receive monthly payments in return for flying the American flag and for allowing the U.S. the right to occupy lands on the islands.
Article IX of the treaty refers to the "government of the sultan." More importantly, the new agreement was meant to put an end to the existing parallel government of the sultan; the sultan continued to rule as before exercising his powers in all aspects of Moro life, collecting taxes, and trying civil and criminal cases.
