Tracing genetic connections of ancient Hungarians to the 6-14th century populations of the Volga-Ural region

Abstract

Most of the early Hungarian tribes originated from the Volga-Kama and South-Ural regions, where they were composed of a mixed population based on historical, philological, and archaeological data. We present here the uniparental genetic makeup of the medieval era of these regions that served as a melting pot for ethnic groups with different linguistic and historical backgrounds. Representing diverse cultural contexts, the new genetic data originates from ancient proto-Ob-Ugric people from Western Siberia (6th-13th century), the pre-Conquest period, and subsisting Hungarians from the Volga-Ural region (6th-14th century) and their neighbours. By examining the eastern archaeology traits of Hungarian prehistory, we also study their genetic composition and origin in an interdisciplinary framework. We analysed 110 deep-sequenced mitogenomes and 42 Y-chromosome haplotypes from 18 archaeological sites in Russia. The results support the studied groups genetic relationships regardless of geographical distances, suggesting large-scale mobility. We detected long-lasting genetic connections between the sites representing the Kushnarenkovo and Chiyalik cultures and the Carpathian Basin Hungarians and confirmed the Uralic transmission of several East-Eurasian uniparental lineages in their genepool. Based on phylogenetics, we demonstrate and model the connections and splits of the studied Volga-Ural and conqueror groups. Early Hungarians and their alliances conquered the Carpathian Basin around 890 AD. Re-analysis of the Hungarian conquerors maternal genepool reveals numerous surviving maternal relationships in both sexes; therefore, we conclude that men and women came to the Carpathian Basin together, and although they were subsequently genetically fused into the local population, certain eastern lineages survived for centuries.
