Seven mitochondrial genomes from Mid–Late Avar contexts in Hungary reveal a heterogeneous maternal signal: haplogroups X, B, K, N, and H are each present in single individuals. This mix is noteworthy because some haplogroups (for example, B and certain lineages of N) are more commonly associated with eastern Eurasian or steppe‑related ancestries, while H, K, and X are widespread across western Eurasia. Archaeological data indicates that the sampled burials come from multiple counties—Bács‑Kiskun, Csongrád‑Csanád, Hajdú‑Bihar, and Jász‑Nagykun‑Szolnok—suggesting geographic spread, but genetic sample counts remain low (n=7).
No robust pattern of Y‑chromosome lineages is reported across these samples, so paternal ancestry and sex‑biased mobility remain unresolved. The maternal diversity, however, is consistent with a scenario of admixture or sustained contact between steppe‑affiliated groups and local Carpathian Basin populations. Limited evidence suggests both eastern and western maternal components were present in this community mosaic.
Because fewer than ten genomes are available, conclusions must be treated as preliminary: observed mtDNA diversity hints at complex demography but cannot alone resolve proportions of ancestry, timing of admixture, or social patterns of marriage and mobility. Future work that increases sample numbers, includes autosomal data, and compares contemporaneous Avar and neighboring populations will be necessary to move from suggestive patterns to robust models of population history.
