 At the dawn of the 20th century, the US government established day schools, missions, farming bureaus, and clinics on every Indian reservation.This policy required that every reservation set up its own police force, tribal courts, and appoint a leader who would represent their tribe to the U.S government.In 1910 in the Census for Indians, the Hopi Tribe had a total of 2,000 members, which was the highest in 20 years.
