The Huns suddenly appeared in Europe in the 370s, establishing one of the most influential although short-lived empires in Europe. Scholars have long debated whether the Huns were descended from the Xiongnu. In fact, the Xiongnu Empire dissolved around 100 CE, leaving a 300-year gap before the Huns appeared in Europe. Can DNA lineages that bridge these three centuries be found?
To address this question, researchers analyzed the DNA of 370 individuals that lived in historical periods spanning around 800 years, from 2nd century BCE to 6th century CE, encompassing sites in the Mongolian steppe, Central Asia, and the Carpathian Basin of Central Europe. In particular, they examined 35 newly sequenced genomes ranging from: a 3rd-4th century site in Kazakhstan and 5th-6th century contexts in the Carpathian Basin, including exceptional Hun-period burials that exhibit Eastern or “steppe” traits often linked to nomadic traditions (i.e. “eastern-type” burials).
The study was carried out as part of the ERC Synergy Grant project HistoGenes (No. 856453), by a multidisciplinary research team of geneticists, archaeologists and historians, including researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. The results showed that there was not a large Asian- or steppe-descended community living in the Carpathian Basin after the Huns’ arrival. However, they identified a small but distinct set of individuals – often belonging to the “eastern-type” burials – who did carry significant East Asian genetic signatures. Advanced comparisons of genealogical connections (the analysis of shared DNA segments known as identical-by-descent, or IBD) led to a remarkable discovery.
Co-first author Guido Alberto Gnecchi-Ruscone of the Max Planck Institute for Evolutionary Anthropology adds: “It came as a surprise to discover that few of these Hun-period individuals in Europe share IBD links with some of the highest-ranking imperial elite individuals from the late Xiongnu Empire”. These connections also include an individual from the largest terrace tomb ever discovered in a Xiongnu context.
