Hungarian Conquerors were rich in Y-haplogroup N (Fóthi et al. 2020)

According to historical sources, ancient Hungarians were made up of seven allied tribes and the fragmented tribes that split off from the Khazars, and they arrived from the Eastern European steppes to conquer the Carpathian Basin at the end of the ninth century AD. Differentiating between the tribes is not possible based on archaeology or history, because the Hungarian Conqueror artifacts show uniformity in attire, weaponry, and warcraft. We used Y-STR and SNP analyses on male Hungarian Conqueror remains to determine the genetic source, composition of tribes, and kin of ancient Hungarians. The 19 male individuals paternally belong to 16 independent haplotypes and 7 haplogroups (C2, G2a, I2, J1, N3a, R1a, and R1b). The presence of the N3a haplogroup is interesting because it rarely appears among modern Hungarians (unlike in other Finno-Ugric-speaking peoples) but was found in 37.5% of the Hungarian Conquerors. This suggests that a part of the ancient Hungarians was of Ugric descent and that a significant portion spoke Hungarian. We compared our results with public databases and discovered that the Hungarian Conquerors originated from three distant territories of the Eurasian steppes, where different ethnicities joined them: Lake Baikal-Altai Mountains (Huns/Turkic peoples), Western Siberia-Southern Urals (Finno-Ugric peoples), and the Black Sea-Northern Caucasus (Caucasian and Eastern European peoples). As such, the ancient Hungarians conquered their homeland as an alliance of tribes, and they were the genetic relatives of Asiatic Huns, Finno-Ugric peoples, Caucasian peoples, and Slavs from the Eastern European steppes.

Genes don't speak languages, people do. Thus, associations between genetic markers and languages may often not be easy to discern, especially with time. This is the case when it comes to Y-chromosome haplogroup N and the Hungarian language.

I briefly discussed this problem not long ago in the context of new ancient DNA samples from medieval Hungary (see here). Today, a detailed paper on the topic by Post et al. was published at Scientific Reports (open access here). It brings together evidence from modern and ancient DNA, linguistics and archeology to argue that Hungarian was introduced into the Carpathian Basin during the Middle Ages by migrants from near the Ural Mountains rich in Y-haplogroup N3a4-B539. Below is the paper abstract, emphasis is mine:

Hungarians who live in Central Europe today are one of the westernmost Uralic speakers. Despite of the proposed Volga-Ural/West Siberian roots of the Hungarian language, the present-day Hungarian gene pool is highly similar to that of the surrounding Indo-European speaking populations. However, a limited portion of specific Y-chromosomal lineages from haplogroup N, sometimes associated with the spread of Uralic languages, link modern Hungarians with populations living close to the Ural Mountain range on the border of Europe and Asia. Here we investigate the paternal genetic connection between these spatially separated populations. We reconstruct the phylogeny of N3a4-Z1936 clade by using 33 high-coverage Y-chromosomal sequences and estimate the coalescent times of its sub-clades. We genotype close to 5000 samples from 46 Eurasian populations to show the presence of N3a4-B539 lineages among Hungarians and in the populations from Ural Mountain region, including Ob-Ugric-speakers from West Siberia who are geographically distant but linguistically closest to Hungarians. This sub-clade splits from its sister-branch N3a4-B535, frequent today among Northeast European Uralic speakers, 4000–5000 ya, which is in the time-frame of the proposed divergence of Ugric languages.
