* Bartolomé de las Casas was a 16th-century Spanish missionary and Dominican friar. He was a vocal critic of the brutal treatment of Indigenous people by the Spanish conquistadors in the Americas. He wrote extensively about the atrocities he witnessed, and his writings helped to spark a debate in Europe about the morality of colonialism.
