Elizabeth A.R. Brown, Emerita Professor of History, Brooklyn College and the Graduate Center, City University of New York, writes at Britannica.com:
…historiographic construct designating the social, economic, and political conditions in western Europe during the early Middle Ages, the long stretch of time between the 5th and 12th centuries. Feudalism and the related term feudal system are labels invented long after the period to which they were applied. They refer to what those who invented them perceived as the most significant and distinctive characteristics of the early and central Middle Ages.
…From the time of the French historian Louis Chantereau Le Febvre (1588–1658), questions were raised concerning the extent to which the feudal construct oversimplified and distorted the historical realities it was intended to capture. Chantereau Le Febvre denounced as futile the attempts of his contemporaries to deduce general rules from uncertain principles. He stressed the necessity of studying authentic acts and working “historically,” implying thereby that his contemporaries were not working in this fashion. He cautioned against reducing the great variety of fiefs to a single type, because each fief was different from the others. Despite Chantereau Le Febvre’s reservations, in the end he succumbed to current fashion and endorsed a simplified picture of feudal institutions. He did, however, edit and publish medieval documents demonstrating the difficulty of attaching precise meanings to such words as feudum and allodium.
Many modern historians have attempted to follow Chantereau Le Febvre’s admonitions and have studied these words and others, such as vassus (“vassal”), homo (“man”), and fidelis (“the faithful”), which figured centrally in the classic definitions of the feudal construct. By examining the contexts in which key words appear in a host of medieval acts and chronicles, they have demonstrated the wide range of meanings these words possessed and the difficulty of formulating simple and precise definitions of any of them. It is clear that in the Middle Ages those who fought (like those who farmed) were rewarded in different ways and were sometimes paid in money. Land was owned, controlled, and held in a variety of ways. Similarly, enterprising individuals used a range of tactics to augment their lands and wealth and increase their power. Standardization and regularization of tenurial and territorial bonds and of ceremonies such as homage accompanied the development of centralized government, as lords and kings utilized these devices (and many others) to buttress and extend their authority.
The extent to which surrender of property to a lord as a fief limited control and rights over the property has been investigated, as has the importance of such acts in creating ties between family groups that could be repeatedly renewed. The difficulty and danger of drawing sharp distinctions between the ceremonial practices of the nobility and the peasantry have been recognized, so too the importance of urban and parochial communities and the significance of spiritual and economic links between religious establishments and the laity. In studying the settlement of disputes, historians have emphasized the continuing importance of mediation and of judgments given by free men, especially members of the secular and ecclesiastical elite. Lordship has emerged as a more centrally important topic than the feudum. The quality of lords’ relationships with their dependents, free and unfree, has been debated, with some historians stressing the predatory, exploitative aspects of lordship and others emphasizing its protective, beneficial features.
Increased knowledge of the Middle Ages and greater sophistication regarding the constructs (and periods) that scholars have created in attempting to comprehend the past have sparked the search for appropriate terms to describe human institutions and societies. Although the feudal labels have lost their validity as terms to designate the realities of medieval society, they provide insight into the thought processes and assumptions of the lawyers and historians who formulated and utilized them between the 16th and the 20th century.”
