A groundbreaking discovery in York, England, has unearthed a new chapter in ancient human migration. Researchers analyzing the remains of a Roman-era man, believed to be a gladiator or enslaved soldier, found he had 25% Scandinavian ancestry.
This revelation indicates significant population movements across Europe centuries before the Viking Age.
Major migration waves across early Europe
The study, led by geneticists and archaeologists, examined ancient DNA from over 1,500 individuals who lived between 1 CE and 1000 CE.
Researchers identified three major waves of migration that shaped the genetic landscape of early Europe.
The findings challenge long-held assumptions about the origins and timing of migration patterns, revealing that human movement was more dynamic and widespread than previously understood.
Scandinavian ancestry reaches southern Europe
One of the most striking discoveries is that Scandinavian ancestry appeared in regions as far south as Italy, Slovakia and southern Britain during the early Iron Age.

Genetic evidence confirms that groups from Scandinavia and northern Germany migrated southward, blending with local populations. These movements not only influenced genetic diversity but also played a role in spreading Germanic languages across Europe.
In southern Europe, researchers discovered a unique individual with entirely Scandinavian ancestry, further underscoring the extent of genetic mixing during this period.
Such findings suggest that migrations were not isolated events but part of broader patterns that reshaped the cultural and genetic fabric of Europe.
Central European migration into Scandinavia
Between 300 and 800 CE, the direction of migration shifted. DNA evidence from Viking-era remains in southern Scandinavia reveals a mix of local and Central European ancestry.
Archaeological findings in Sweden suggest that migrants from Central Europe settled in Scandinavia and became part of the local population.
Ancient DNA unlocks new understanding of migrations in the first millennium AD. The research employs a new method called Twigstats1, which provides a detailed analysis of ancient DNA to uncover migrations in Europe during the first millennium AD.

Researchers theorize that conflicts in Central Europe may have driven these movements northward, resulting in a lasting impact on Scandinavian ancestry just before the Viking Age.
Genetic links to the Viking Age
The Viking Age (c. 800–1050 CE) is famously associated with raids and settlements across Europe. Genetic analysis aligns with historical accounts, showing Scandinavian ancestry in Viking-era individuals from Britain, Ukraine, and Russia.
Some Vikings buried in British mass graves had direct genetic links to Scandinavia, highlighting their involvement in military campaigns and raids.
These discoveries were made possible by a cutting-edge tool called Twigstats, which allows scientists to track subtle genetic changes over time. Leo Speidel, the study’s lead author, emphasized its significance in uncovering hidden migration patterns and providing a clearer picture of Europe’s complex history.
Peter Heather, a medieval historian and co-author, noted that historical texts often hinted at large-scale migrations. However, the true nature and extent of these movements remained unclear. The genetic evidence presented by this study offers a definitive perspective, resolving debates about how migrations shaped Europe’s early populations.
