Scientists: Some Early Vilnius Residents Were Migrants from Kyivan Rus'

Scientists have uncovered evidence suggesting that some of the earliest residents of Vilnius were migrants from Kyivan Rus'. Researchers from Vilnius University analyzed human remains found in a 13th-14th century cemetery in the city's Rusyn quarter. By examining carbon, nitrogen, oxygen, and strontium isotopes preserved in teeth and bones, they determined the dietary patterns and potential origins of 15 individuals. The analysis revealed that the men buried in the cemetery were highly mobile and likely not local. One young man, in particular, showed dietary patterns in his youth consistent with regions south of Lithuania, leading researchers to believe he may have originated from Kyivan Rus'. Rytis Jonaitis, a scientist from the Lithuanian Institute of History and one of the leaders of the Bokšto Street cemetery study, noted that archaeologists had previously suspected the presence of migrants from Rus' lands within the city's community. However, the isotope data now confirms that at least some of the individuals buried there came from regions outside Lithuania. The study also indicated that most women buried in the cemetery were of local origin. This suggests that early Vilnius communities were formed through migration and mixed marriages, with Christianity potentially spreading to Lithuania via these interactions. The Bokšto Street cemetery is one of the largest known medieval Christian burial sites in pagan Lithuania. Despite Lithuania still being pagan during the 13th-14th centuries, the findings show that those buried there followed Orthodox Christian burial traditions. The research, combining anthropology, archaeology, and isotopic analysis, allows for the direct identification of individuals who changed their diet, location, and migrated to medieval Vilnius during its formative period. This study highlights Vilnius's ethnic diversity from its earliest days, fitting the criteria of a dynamically growing cultural and economic center. Researchers suggest that people may have migrated to Vilnius for political ties, trade, religious reasons, or better living conditions, especially after the plague devastated much of Europe in the mid-16th century. The findings underscore that medieval cities were dynamic and diverse spaces shaped by people from various cultures.

By combining anthropology, archaeology, and isotopic studies from different human tissues, which form during different periods of human life, we can for the first time directly identify individuals who changed their diet and place of residence and migrated to medieval Vilnius during the city's formation period.
