4- People pledged absolute loyalty to their social superiors.
Step-by-step explanation:
It´s curious, but feudal society in both Japan and Europe is characterized by a rigid social structure supported by religious principles to a large extent. Feudal Europe was Christian, and it was believed that a person social place was determined by God´s will. In Japan, Buddhism and Confucianism endorsed a rigid social order. In both cases , there were usually very few chances for a person to move upwards in the social ladder. In both medieval Japan and medieval Europe all people had to sworn in and show loyalty to superiors; peasants to their lords, the feudal lords to the king or the shogun.
