Answer:
The correct answer is: they practiced Islam and traditional native beliefs .
Step-by-step explanation:
In 1415, King Henry of Portugal (also known as Henry the Navigator) led an attack on Ceuta (a town located in Morocco) with his father and his brothers. When Henry conquered Ceuta, he became obsessed with Africa, especially with his biggest desire, to conquer the Muslims who lived there and convert them into Christians.
He was convinced that he could convert the African Muslim population into good Christians, as they practiced and strictly obeyed Islam and its traditional native beliefs. Those characteristics were particularly adequate for King Henry to spread the Christian influence.
