History
From the late eighth century, Scandinavian Viking raiders targeted the coasts of northern Gaul and started to raid along the river Seine during the 9th century with the first Viking attack up the Seine river taking place in 820.
Monastic centres such as Jumièges Abbey and Saint-Wandrille were plundered repeatedly; Rouen itself was attacked and temporarily abandoned in 841.
As early as 841, a Viking fleet appeared at the mouth of the Seine, the principal route by which they entered the kingdom. After attacking and destroying monasteries they took advantage of the power vacuum created by the disintegration of Charlemagne's empire to occupy Northern France.
