Blonde Scandinavians or well-travelled Southern Europeans


Our notion of the Scandinavian Viking very likely stems from films rather than history. In reality, their genome contains lots of genes from Southern and Eastern Europe, which also implies that they had dark rather than blond hair. And within the Scandinavian borders, the Vikings did not really mix genetically; instead, they travelled abroad on plundering raids. This is revealed by new research from the University of Copenhagen.

When we talk of Nordic history, it is all but impossible not to mention the Vikings. Stories about the Scandinavian warriors and their Old Norse Gods have long since travelled all around the world. But perhaps part of that narrative is only based on myths and brought to life by popular culture. At least, this is what is indicated by a new study from the University of Copenhagen.

The study is the biggest genetic study of Vikings ever. The researchers have sequenced the genome of 442 bone fragments from the Viking Age, from all over Europe, and they have made some rather surprising discoveries. Among other things, the Vikings may not be quite as Nordic as hitherto believed.

“The Vikings had a lot more genes from Southern and Eastern Europe than we anticipated. They frequently had children with people from other parts of the world. In fact, they also tend to be dark-haired rather than blond, which is otherwise consider an established Viking-trait,” Professor at Lundbeck Foundation Center for Geogenetics at the GLOBE Institute at the University of Copenhagen, Eske Willerslev, explains.

Peasants missed out on the Bronze Age

The new study also reveals that generally Vikings were a lot more genetically diverse than the peasant societies on the Scandinavian mainland.

“The Vikings lived in coastal areas, and genetically speaking, they were an entirely different people to the peasant societies living further inland. The mainland inhabitants had a lot less in common with the Vikings than the peasants who lived in Europe thousands of years ago. You could almost say that genetically speaking, the peasants missed out on the entire Iron and Bronze Age,” co-author of the study and Assistant Professor at the Center For Geogenetics at the GLOBE Institute, Ashot Margaryan explains.

However, the Viking’s diverse genome stems not merely from people from elsewhere travelling to their settlements. In fact, they were themselves avid travellers, and historically, we know them best for their plundering and murdering raids abroad. But this genetic study sheds new light on who went where.

“The Danish Vikings went to England, while the Swedish Vikings went to the Baltic and the Norwegian Vikings went to Ireland, Iceland and Greenland. However, the Vikings from these three ‘nations’ only very rarely mixed genetically. Perhaps they were enemies or perhaps there is some other valid explanation. We just don’t know,” Ashot Margaryan says.
