New Genetic Study Reshapes the Picture of Early Medieval Settlement in Southern Germany

How was southern Germany settled after the end of the Western Roman Empire? An international research team has now provided new answers to this central question in European history. For a long time, the prevailing view held that large Germanic groups migrated into the territory south of the Roman limes after the collapse of Roman rule and repopulated the region. However, current genetic analyses paint a much more nuanced picture.

For the study, researchers analyzed the genomes of individuals who lived between 400 and 700 CE. The examined skeletal remains originate from early medieval row grave cemeteries in southern Germany, including several sites in Bavaria such as Weilheim, Ergoldsbach, Burgweinting, and the cemetery of Essenbach-Altheim in the district of Landshut. These burial grounds are of particular interest because they are located in close proximity to the former Danube limes, providing important insights into the transitional period between Late Antiquity and the Early Middle Ages.

The results show that settlement did not occur through single large-scale conquests, but rather through smaller, gradual migration movements. Following the collapse of Roman administrative structures, different population groups came into contact with one another: people with northern roots encountered already established communities from Roman-influenced cities and military settlements, which were themselves genetically diverse. Within just a few generations, these groups underwent extensive admixture.

What is particularly remarkable is the speed of this process: only around 150 years after the end of Roman rule, the genetic composition of the population south of the limes already closely resembled that of present-day Central Europeans. The researchers attribute this rapid integration partly to shared cultural traditions. Late Roman ways of life and social structures may have played a unifying role.

The reconstruction of social structures also provides fascinating insights: society was predominantly organized around nuclear families, marriages were monogamous, and unions between close relatives were avoided. Particularly striking is the finding that inheritance rights were passed on through both daughters and sons — an indication of comparatively stable and balanced family structures.

Anthropologists Michaela Harbeck and Maren Velte of the Bavarian State Collections of Natural History (SNSB) made an important contribution to the study. In addition to providing key collection materials, osteological and isotopic analyses were carried out at the anthropological collection in Munich. These analyses offered further insights into the origin and mobility of the individuals examined and confirmed the genetic findings.

The study vividly demonstrates how closely biological and cultural developments are intertwined and opens up new perspectives on population development during the transition from Antiquity to the Middle Ages. At the same time, it highlights the great potential of interdisciplinary research for understanding key periods of European history.

The project was initiated by researchers from the University of Tübingen, the University of Freiburg, the SNSB, and the Bavarian State Office for Monument Protection. It also involved population geneticists from Johannes Gutenberg University Mainz and the University of Freiburg. The research was funded by the German Research Foundation (DFG) במסגרת the Tübingen research group 2496 “Migration and Mobility in Late Antiquity and the Early Middle Ages” as well as by the Swiss National Science Foundation (SNF).
