About
Rollo was a Viking leader who raided the Seine until the King of the Franks gave him the land at the river's mouth to stop him, by the treaty of Saint-Clair-sur-Epte in 911. That land became Normandy, and Rollo became the founder of a line that produced every Duke of Normandy and, after 1066, every king of England. He stands at the historical horizon of this family's Norman descent; above him is saga rather than record.
