Feudalism started around A.D. 900.
Feudalism is the denomination of the predominant political system in Western Europe in the Late Middle Ages (between the 9th and 15th centuries, although there is no agreement among historians about its beginning and duration, and this varies according to the region), and in Europe Eastern during the Modern Age, characterized by the decentralization of political power; based on the diffusion of power from the top (where in theory were the emperor or kings) to the base where local power was exercised effectively with great autonomy or independence by an aristocracy, called nobility.
