Sigtuna’s International Demographics

Genomic studies are published at a fast rate these days.

Sigtuna, a medieval Swedish trading town, emerges as an international hotspot by the 980s. It is at the heart of the complex of trading routes on Lake Mälaren and to the Baltic Sea. It is of commercial importance, and boasts a royal and religious connection.2 Its demography shows more men than women lived in town, and that their dietary habits differed. The diets differed, too, between the social classes. And evidence of illnesses indicate how close the people lived together.3

The long-standing belief among scholars is that Sigtuna was more international than one would think. The new study, based on genomic and strontium analyses, confirms this. The researchers used 23 human remains, of which they also took 16 teeth samples and combined this with 15 further teeth samples. The results are clear. They show a high diversity in the population. Of the sample group, half are locals but the other half, predominantly women, originate from other places in northern Europe. In a few cases, the team thinks they can even point out first-generation and second-generation immigrants.

At this rate, Sigtuna might well reveal the most comprehensive demographic picture of an international Viking Age trading town.
