Abstract

Materials and methods. The article analyzed the 67-marker Y-STR haplotypes of I1-M253 Azerbaijanis from the northwestern region of Azerbaijan (Gabala and Aghdash districts). Based on the characteristic DYS values, the entire group of studied haplotypes can be reliably assigned as I1-BY453 subclade. Time to the most recent common ancestor (TMRCA) was estimated using infinite allele mutation model with a probability of 95% and an average generation interval of 31 years. Results. TMRCA calculated as 35 generations. Taking into account the average generation interval of 31 years, that population can be traced to common male ancestor who lived ~1085 years ago (in the middle of the 10th century). The location map of the closest to the considered group matched haplotypes includes the adjacent areas of modern Denmark and southern Sweden. The ancestor of the studied group of Azerbaijanis, apparently, arrived from this territory during the Caspian expeditions of the Vikings on the state of the Shirvanshahs in the 9th-11th centuries. In Denmark and Sweden, this time fits with the reign of the Danish House of Knytlinga. Conclusion. A comparative analysis of the data suggests that the presence of haplogroup I1-M253 (TMRCA ~1000 years) in Transcaucasia clearly indicates the fact of one-time contacts with Denmark and Sweden during the Knytlinga dynasty and can be correlated with the period of the Viking Caspian expeditions on the state of the Shirvanshahs during IX-XI centuries.
