Feudalism is defined as a Medieval European political, economic and social system from the 9th to 15th century.
A broader definition of feudalism, as described by Marc Bloch (1939), includes not only the obligations of the warrior nobility but those of all three estates of the realm: the nobility, the clergy, and the peasantry bound by manorialism; this is sometimes referred to as a feudal society.is classic definition of feudalism is widely accepted today among medieval scholars, though questioned both by those who view the concept in wider terms and by those who find insufficient uniformity in noble exchanges to support such a model.
