We often think of the Vikings as ultimate explorers, taking their culture with them to far-off lands. But we may not typically think of Viking age Scandinavia as a hub for migration from all over Europe.
In a study published in Cell, we show this is exactly what happened. The Viking period (late 8th century to mid 11th century) was the catalyst for an exceptional inflow of people into Scandinavia. These movements were greater than for any other period we analysed.
