The Controversy of Valladolid

I have recently studied a play which is entitled " The controversy of Valladolid " which I like much. The controversy of Valladolid took place in Valladolid in 1550; it's about the status of the Native Americans discussed by the Dominican Bartolomé de Las Casas and the theologian Sepúlveda. I liked it a lot because it is a real tragedy; maybe it would happen even today. If you want to know this atrocious period, read it then share your comments with me. Thank you. Armelle, STGang
