Feudalism
Definition

The adjective feudal was in use by at least 1405, and the noun feudalism was in use by the end of the 18th century, paralleling the French féodalité.

According to a classic definition by François Louis Ganshof (1944), feudalism describes a set of reciprocal legal and military obligations of the warrior nobility that revolved around the key concepts of lords, vassals and fiefs, though Ganshof himself noted that his treatment was only related to the "narrow, technical, legal sense of the word."

A broader definition, as described in Marc Bloch 's Feudal Society (1939), includes not only the obligations of the warrior nobility but the obligations of all three estates of the realm: the nobility, the clergy, and those who lived off their labour, most directly the peasantry, which was bound by a system of manorialism. This order is often referred to as a feudal society, echoing Bloch's usage.

Outside its European context, the concept of feudalism can be extended to analogous social structures in other regions, most often in discussions of feudal Japan under the shoguns, and sometimes in discussions of the Zagwe dynasty in medieval Ethiopia, which had some feudal characteristics (sometimes called "semifeudal"). Some have taken the feudalism analogy further, seeing feudalism (or traces of it) in places as diverse as Spring and Autumn period China, ancient Egypt, the Parthian Empire, India until the Mughal dynasty and the Antebellum South and Jim Crow laws in the American South.

The term feudalism has also been applied—often pejoratively—to non-Western societies where institutions and attitudes similar to those in medieval Europe are perceived to prevail. Some historians and political theorists believe that the term feudalism has been deprived of specific meaning by the many ways it has been used, leading them to reject it as a useful concept for understanding society.

The applicability of the term feudalism has also been questioned in the context of some Central and Eastern European countries, such as Poland and Lithuania, with scholars observing that the medieval political and economic structure of those countries bears some, but not all, resemblances to the Western European societies commonly described as feudal.
