Step-by-step explanation:
During the period from 600 C.E. to 1450 C.E., both Europe and Japan used a method of control known as feudalism. Feudalism is a political and social system in which land is exchanged for loyalty and military service. In Europe, feudalism was characterized by a hierarchy of lords, knights, and peasants, with land being granted in exchange for military service. In Japan, feudalism was similar, with the shogun, daimyo, samurai, and peasants forming a hierarchical system based on land ownership and loyalty.
