Pedro de Cordoba

Pedro de Córdoba OP (c.1460–1525) was a Spanish missionary, author and inquisitor on the island of Hispaniola. He was first to denounce the Spanish system known as the Encomienda, which amounted to the practical enslavement of natives of the New World, for the abuses that it engendered.
