In History of the Indies (1561), released five years before his death, Las Casas regretted “the advice he gave the king” to import enslaved Africans. He saw in Zurara’s writing evidence revealing the slave trade to “be the horror that it is.” Las Casas lamented Zurara’s attempt “to blur [the slave trade] with the mercy and goodness of God.” Las Casas tried to close the door on African slavery, after opening it for so many Spanish slaveholders. He failed.
