Bartholomew de Las Casas
Bartholomew de Las Casas lived from 1474 to 1566. He was a Dominican monk and missionary. He was assigned to be the chaplain for the Spanish Armies during their invasion of Cuba and witnessed first-hand a horrible massacre of the native people. As a result, he sent sensational descriptions to the Spanish government of the supposed atrocities the Conquistadors were committing against the natives out of concern that the actions were undermining attempts to spread Christianity. He was deeply concerned about the souls of the natives. Las Casas' reports resulted in the new Repartamientos, rules for the treatment of the natives.
