New Research Offers a Totally New Viewpoint on the Ancient Avar Society That Dominated Eastern Central Europe

Exploring the kinship, social customs, and transformations of early medieval steppe communities in Europe through ancient DNA and archaeological evidence.

The Avars, originating from Eastern Central Asia, dominated large parts of Eastern Central Europe for over two and a half centuries, from the 6th to the 9th century CE. They are perhaps not as well-known as the Huns, their less successful predecessors.

Yet in their cemeteries, they left one of the richest archaeological heritages in European history, including around 100,000 graves that have so far been excavated. From Avar funeral customs, and from written reports of their neighbors, scholars have reconstructed some of their social practices and ways of life. Yet now, archaeogenetics offers a totally new viewpoint on Avar communities who lived more than 1000 years ago. We can now analyze the ways in which individuals were related to each other up to the sixth to the tenth degree.

By combining newly generated ancient DNA data with complementary archaeological, anthropological, and historical information, a team of the multidisciplinary Synergy Grant research project HistoGenes funded by the European Research Council (ERC) has thus opened new ways to find out more about kinship patterns, social practices and population development in the distant past.

The team includes researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, together with Hungarian, Austrian, and US research groups. In their collaboration, they set new standards by using all available methods, including the most advanced genetic and bioinformatic tools.

Studying whole communities

The historical knowledge of the Avar period populations was passed on to us by their enemies, mainly the Byzantines and the Franks, so we lack information on the internal organization of their clans. Women are particularly underrepresented in historical sources, with only three incidental mentions, so knowledge of their lives is practically non-existent. We know that some groups came to Europe from the East Asian and Pontic steppes, but to what extent, if at all, were steppe traditions maintained in Avar society if at all?

How did the newcomer groups from the East interact with each other and with the population of their new homeland in Europe? In essence, how did their way of life change over time in a completely new environment after they left the steppes and abandoned their nomadic way of life?

The study was carried out as part of the ERC Synergy Grant project HistoGenes (No. 856453), by a multidisciplinary research team of geneticists, archaeologists, anthropologists, and historians, including researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, the Institute of Archaeological Sciences and Department of Biological Anthropology at Eötvös Loránd University (ELTE), Institute of Archaeogenomics, HUN-REN Research Centre for the Humanities, Budapest, Hungary, the Curt Engelhorn Center for Archaeometry in Mannheim, Germany, the Institute for Austrian Historical Research of the University of Vienna, Austria, the Institute for Advanced Study in Princeton, USA, and others. Contrary to common practice in ancient DNA research, the team aimed to study whole communities and therefore focused on sampling all available human remains from four fully excavated Avar period cemeteries.

Thanks to exceptional ancient DNA preservation, they were able to analyze a total of 424 individuals and discovered that around 300 had a close (1st and 2nd degree) relative buried in the same cemetery. This allowed the reconstruction of several extensive pedigrees, the largest of which is nine generations deep and spans about 250 years.

Community dynamics

The researchers were able to identify communities that practiced a strict patrilineal descent system, where patrilocality (male individuals staying in the community after marriage) and female exogamy (female individuals moving to their partner’s community after marriage) were the norm. Communities were locally centered around a main patriline, and were related to each other through the systematic practice of female exogamy.

Zuzana Hofmanová, senior author of the study says: “In a way, this pattern shows the role of females in promoting the cohesion of this society, it was the role of females that connected the individual communities”. Multiple reproductive partners were common. Several independent cases show that these communities practiced so-called levirate unions. This practice involves related male individuals (siblings or father and son) having offspring with the same female individual.

Avar Period Cemetary

Guido Alberto Gnecchi-Ruscone, first author of the study, adds: ”These practices, together with the absence of genetic consanguinity, indicate that the society maintained a detailed memory of its ancestry and knew who its biological relatives were over generations.”

These social practices are consistent with evidence from historical sources and anthropological research on Eurasian Steppe societies. Thanks to the high resolution provided by the extensive pedigrees and whole-cemetery data, the researchers were also able to identify a clear temporal transition within one of the sites analyzed. This was revealed by the shift from one patriline to another and by changes in patterns of distant relatedness (the network of genetic relatedness, i.e. the IBD-network).

Zsófia Rácz, co-first author of the study, says: “This community replacement reflects both an archaeological and dietary shift that we discovered within the site itself, but also a large-scale archaeological transition that occurred throughout the Carpathian Basin.” This change, probably related to political changes in the region, was not accompanied by a change in ancestry and would therefore have been invisible without the study of whole communities. This finding highlights how genetic continuity at the level of ancestry can still conceal replacements of whole communities, and has important implications for future studies comparing genetic ancestry and archaeological shifts.

  1. No doubt but that it was the horse that owned the young man, rather than the other way around;we need only look around ourselves to see that are nothing more than some other animal pet.
