The Quakers were motivated by high ideals, played down the role of conversion, and worked well with the Indians. They had been highly organized and motivated by the anti-slavery crusade, and after the Civil War expanded their energies to include both ex-slaves and the western tribes. They had Grant's ear and became the principal instruments for his peace policy. During 1869–1885, they served as appointed agents on numerous reservations and superintendencies in a mission centered on moral uplift and manual training. Their ultimate goal of acculturating the Indians to American culture was not reached because of frontier land hunger and Congressional patronage politics.
