The article is devoted to the condition of lieges from Scalovia in the State of Teutonic Order, who possessed land estates of 2–6 hakens and were obliged to keep military service and built fortifications. Among representatives of this group, whose possessions were located mainly near the rivers Memel and Jura, there was accumulation of property and fragmentation of land estates. By stabilizing landholding, the Order could receive regular growing in number of lieges, that testified to successful incorporation of Scalovians in the new social system.
