Average body height of the middle and lower social classes in the middle European Germanic settlement area from the early Middle Ages to modern times

This paper reviews the body height data of middle and low social classes of North and Central European populations from the early Middle Ages until the beginning of the 17th century. It is mainly based on anthropological data from the ancient Germans, but considers also some historical reports. From the data presented here it is seen that the initially rather considerable body heights in these two social groups are decreasing during the Middle Ages. This could be observed on population samples from the Central German Highlands and from Southern Germany as well as on samples from the utmost Western Teutonic settlement: Greenland. The reasons for these variations are most likely to be seen in nutritional changes, in increasing hard physical work due to the transition to predominating agriculture, in biological effects of birthrights, and in deteriorating hygienic conditions.
