Answer:
Feudal Japan and Medieval Europe saw a similarity in the social classes. In Japan, it was Samurai (Bushi) and in Europe it was Knights. They both had to follow codes of honor, had to be loyal and brave but at the same time, they had to be reserved and quiet. They both were the proctors of the King and Lords. In some context, it has been seen Samurai as a personal guard for the nobles in Japan as well as in Europe, Knights as a protector of the nobility class.
