234 THE HISTORY OF MEDIEVAL EUROPE estate where one man owned all the land and every one else living on the estate worked for him ; and that in the German kingdoms established upon Roman soil many of the once free German warriors soon sank to a position of economic dependence and social inferiority — in short, to serfdom. The serfs had to cultivate part of the estate for their master, to labor in and about his house, cut wood for his fire, cart his grain and wine and hay, repair the roads and bridges on his property. Their lord usually did not feed or clothe or house them, though he would probably provide breakfast and lunch for them when they worked all day in his fields or on his errands.

The lord was far from allowing the serf to keep for him- Seigneurial self all that he raised on his own land. Even of tlon his own wheat and oats and barley, and even of his sheep, pigs, hens, and eggs, he had to hand over a part
