From Science Nordic: New study reignites debate over Viking settlements in England.

The Vikings plundered, raided, and eventually reigned over a large part of what is modern day England. But exactly how many Danish Vikings migrated west and settled down in the British Isles?

In 2015, a large DNA study sparked a row between DNA scientists and archaeologists after concluding that the Danish Vikings had a “relatively limited” influence on the British—a direct contradiction to archaeological remains and historical documents.

“We see no clear genetic evidence of the Danish Viking occupation and control of a large part of England,” write DNA scientists in a study published in the scientific journal Nature in 2015.

A new study has reignited the debate by claiming that somewhere between 20,000 and 35,000 Vikings relocated to England. [continue]
