What did Pope Nicholas V do in 1452 and 1455?
A. He issued two papal bulls that permitted the enslaving of native non-Christians in Africa and the New World.
B. He issued two papal bulls that allowed Europeans to settle in the New World.
C. He issued two papal bulls that scolded Europeans for enslaving Africans and Native Americans.
D. He issued two papal bulls that warned Africans not interact with the Europeans.
I believe that the answer was A in response to the Ottoman Turk's conquest of Constantinople. More like permission for King Alfonso to enslave Muslims who were "enemies" of Christianity.
