Answer:
FEUDAL SYSTEM

In Europe at the midle age ( 500 - 1500 ) Feudalism in western Europe was performed. The society have been class , the upper and the lower class .
UPPER CLASS :- consistes of Knight , noble , kings and clergy.
LOWER CLASS :- consistes of peasants , craftman and merchants .
In feudal system the peasants tribute to the goverment by their labour and income b/c the nobile of the land was hire the lands to the peasant and they can't leave the land . That was their rule .
So the upper class exercise suitabke life but unlike for lower class .
