Why was it so important for a knight to take a vow of loyalty to his lord?
O The knight needed to be sure that the lord would protect him in exchange for his service as a skilled warrior.
O The knight wanted to be sure that his son would inherit his position when either the knight or the lord died.
O Because the lord was a Christian, it was essential for his knight to vow to become a Christian as well.
O Since a knight was a skilled warrior, the lord could be in great danger if the knight betrayed him.
