Bartolome de las Casas, (1484-1566), was a 16th-century Spanish Dominican priest, writer and the first resident Bishop of Chiapas. As a settler in the New World he witnessed, and was driven to oppose, the torture and genocide of the Native Americans by the Spanish colonists and pushed for rights of the natives appealing to the imperial court of Charles V. His stance for African slaves' rights was later than the one for native slavery.
