 Based on the past work by Catholic missionaries among those tribes, the Catholic dioceses had expected allotments to 38 of the 73 reservations.Beginning in 1869, Grant had crafted a policy of close church-state collaboration through the Board of Indian Commissioners as a means to maintain peace with the tribes and to fight the corruption in government that was rampant within the Office of Indian Affairs.In force to 1881, the policy's implementation gave Catholic missionaries exclusive religious domain to the reservations allotted to the Catholic Church, but also denied Native American Catholics on other reservations their freedom of religion to attend local Catholic churches and schools.
