Indian policy in Brazil, as in many countries, was and is a confused mixture of religion, humanitarianism, and greed. Almost every kind of system has been tried: open barter during the early years, undisguised slavery until 1570, lay administrators until 1624, missionary tutelage in some form from 1624 to 1759, with intermittent relapses into lay administration, secularization after 1755, with lay directors until 1798; military administration under civil judges until the end of the empire, and finally in 1910 the establishment of the Indian Service under General Rondón.
