what are the four class levels in feudalism
Feudalism A broader definition of feudalism, as described by Marc Bloch (1939), includes not only the obligations of the warrior nobility but also 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". Since the publication of Elizabeth A. R. Brown's "The Tyranny of a Construct" (1974) and Susan Reynolds's Fiefs and Vassals (1994), there has been ongoing inconclusive discussion among medieval historians as to whether feudalism is a useful construct for understanding medieval society.[4][5][6][7][8][9]
