It was once assumed that nearly all agricultural labourers in medieval Europe were serfs. Serfdom was distinct from slavery in that serfs could contract legitimate marriages, hold personal property and could not be moved around at will. Historians more recently moved away from examining servile condition and its implications and focused on the seigneurial regime and village society with little regard for the influence of status.
In the Middle Ages and indeed in all pre-industrial societies, the vast majority of the population tilled the land. We are still not in a good position to evaluate how noble and ecclesiastical landlords received revenues from lands they were only indirectly engaged in farming, despite this being a basic factor that governed medieval society. What kind of agricultural system provided the impetus for economic growth that so dramatically increased the number of cities and volume of trade?
There is no modern, synthetic book on medieval serfdom that compares regions or draws general conclusions about it. This work attempts such a synthesis and also shows avenues of future research, but most importantly it is intended to reorient attention to the importance of serfdom in the structure of medieval society.
