Las Casas, Bartholomé de, a celebrated Spanish priest, surnamed the Apostle of the Indians, born at Seville; visited the West Indies early under Columbus; took a deep interest in the natives; was grieved to see the usage they were subjected to there, as well as elsewhere, under the rule of Spain, and spent his life in persuading his countrymen to adopt a more lenient and humane treatment; crossed the ocean twelve times on their behalf; was made Bishop of Chiapa, in Mexico, in 1554; died in Madrid (1474‒1566).
