Who was at the top of the feudal system hierarchy

The answer would be the "King." The king is the top of the feudal system hierarchy. The feudal system hierarchy goes from King, to Nobles, to Knights, to Merchants, to Peasants. The feudal system hierarchy or the FSH was the rights and privileges that were given to upper class members. For example nobles were given land, money, and cattle in exchange for military protection to peasants and service to the King.

Hope this helps.
