    In the NRDI FK-127938 research project, we studied three selected contemporary Hungarianspeaking populations of the Carpathian Basin, from the regions of Baranja (Croatia), Zobor-region (Slovakia) and Székely Land (Romania), which had relatively isolated population history in the last centuries. Furthermore we examine ancient DNA of medieval Székely individuals from Udvarhelyszék (Odorheiu Secuiesc) region, in order to gather genetic information from Hungarianspeaking long-time residents of Transylvania and aim to monitor possible continuity and relationships of the region’s populations. Here we provide 18 modern and 24 ancient whole-genome results (2.5-3x coverage for the modern samples and 0.3-0.9x coverage for the medieval samples) from the aforementioned regions and analysed 1240k SNPs (single nucleotide polymorphisms) in the context of geographically and historically relevant populations. We discuss how uniform or different these Hungarian-speaking populations are genetically, and whether a regional genetic structure is observable. A further aim of our research was to unveil genetic relationships between ancient and recent populations. Our results demonstrate a predominantly local uniparental make-up of the populations and indicate limited admixture with neighbouring populations. Presumably due to intra-regional movements, there are no signs of inbreeding in the populations, but a signal of small population size is present. The whole genome results demonstrate the homogeneity and continuity of the medieval Székely population up to the recent Székely population. The results open up new possibilities not only for research on recent populations, but also for comparative analyses of the genetic heritage of populations of historical age. The research has a wider social significance: it provides an opportunity to interpret the genetic composition of contemporary Hungarians in a geographical and historical context.
