Genomic landscape of the medieval Hungarian elite from the Szekesfehervar royal necropolis

We analyzed 399 shotgun genomes from the Royal Basilica of Szekesfehervar, representing the elite of the Medieval Hungarian Kingdom. Our results reveal that the Carpathian Basin population underwent a marked homogenization during the Middle Ages, driven largely by admixture with eastern immigrant groups, especially the conquering Hungarians, resulting in a genomic landscape distinct from that of the surrounding European populations. The European ancestry component also shifted: the Avar-period Balkan element disappeared, while northern and northwestern European ancestry increased, likely reflecting changing political connections. We identified a previously unrecognized Conquest-period stratum at the site, including two individuals closely related to the Arpad dynasty. No large, continuous kinship networks were detected, indicating a dynamic and continuously renewed elite. At the population level, the strongest affinities were observed with the Conq_Asia_Core group and its ancestor, the Karayakupovo horizon, as well as with medieval populations from neighboring regions (present-day Croatia, Serbia, Slovakia, Poland, and Montenegro), reflecting the diverse sources of the medieval Hungarians.

Archaeogenetic analysis revealed East Eurasian paternal origin to the Aba royal family of Hungary

The Aba family played a pivotal role in the early history of Medieval Hungary dominating extensive territories and giving rise to influential figures. We conducted an archaeogenetic examination of remains uncovered at the necropolis in Abasar, the political centre of the Aba clan, to identify Aba family members and shed light on their genetic origins. Utilizing Whole Genome Sequencing (WGS) data from 19 individuals, complemented by radiocarbon measurements, we identified 6 members of the Aba family who shared close kinship relations. Our analysis revealed that 4 males from this family carried identical N1a1a1a1a4[~] haplogroups. Significantly, our phylogenetic investigation traced this royal paternal lineage back to Mongolia, strongly suggesting its migration to the Carpathian Basin with the conquering Hungarians. Genome analysis, incorporating ADMIXTURE, Principal Component Analysis (PCA), and qpAdm, revealed East Eurasian patterns in the studied genomes, consistent with our phylogenetic results. Shared Identity by Descent (IBD) analysis confirmed the family kinship relations and shed light on further external kinship connections. It revealed that members of the Aba family were related to members of prominent Hungarian medieval noble families the Arpads, Bathorys and Corvinus as well as to the first-generation immigrant elite of the Hungarian conquest.

Whole genome analysis sheds light on the genetic origin of Huns, Avars and conquering Hungarians

Huns, Avars and conquering Hungarians were Migration Period nomadic groups which arrived in three successive waves in the Carpathian Basin between the 5th and 9th centuries. Based on historical data each of these groups are thought to have arrived from Asia, although their exact origin and relation to other ancient and modern populations has been debated. In this study we have sequenced 9 Hun, 143 Avar and 113 Hungarian conquest period samples, and identified three core populations, representing immigrants from each period, with no recent European ancestry. Our results suggest that this "immigrant core" of both Huns and Avars originated in present day Mongolia, and their origin can be traced back to Xiongnus. On the other hand, the "immigrant core" of the conquering Hungarians derived from an earlier admixture of Mansis, early Sarmatians and descendants of late Xiongnus. In addition, we detected shared Hun-related ancestry in numerous Avar and Hungarian conquest period genetic outliers indicating a genetic link between these successive nomadic groups. Aside from the immigrant core groups we identified that the majority of the individuals from each period were local residents, harboring "native European" ancestry.

Maternal lineages from 10-11th century commoner cemeteries of the Carpathian Basin

BackgroundNomadic groups of conquering Hungarians played a predominant role in Hungarian prehistory, but genetic data are available only from the immigrant elite strata. Most of the 10-11th century remains in the Carpathian Basin belong to common people, whose origin and relation to the immigrant elite has been widely debated. MethodsMitogenome sequences were determined from 202 individuals with Next Generation Sequencing combined with hybridization capture. Median Joining networks were used for phylogenetic analysis. The commoner population was compared to 87 ancient Eurasian populations with sequence based (Fst) and haplogroup based population genetic methods. ResultsHaplogroup composition of the commoner population markedly differs from the elite and in contrast to the elite, commoners cluster with European populations. Besides, detectable sub-haplogroup sharing indicates admixture between the elite and commoners. ConclusionsMajority of the 10-11th century commoners most likely represent local populations of the Carpathian Basin, which admixed with the eastern immigrant groups including conquering Hungarians.
