Haplogroup R1a-SUR51


R1a-SUR51 is a Y-chromosomal paternal lineage found among modern populations including Bashkirs, Mishars, Hungarians, and Serbs.
The Institute of Hungarian Research determined the whole-genome data of King Béla III of Hungary, which was published in 2020, as well as that of King Saint Ladislaus of Hungary, published in 2023.
The paternal Y chromosome of both members of the Árpád dynasty among the Hungarian royal family belongs to haplogroup R-ARP, a subclade of R1a-SUR51 within the R-Z2123 clade.

Lifetime of a common ancestor between the Árpád dynasty and Bashkirs carrying R1a-SUR51

According to research by Péter L. Nagy, Judit Olasz, and their co-authors, the estimated lifetime of the most recent common paternal ancestor between Bashkir carriers of R1a-SUR51 and the Árpád dynasty dates to the beginning of the Common Era.
In contrast, Bulat A. Muratov has proposed a later divergence date, placing the separation between Bashkir R1a-SUR51 lineages and the Árpád dynasty in the 7th century AD.
