Sack of Santiago de Compostela
In the year 968, a Norwegian Viking fleet led by Gunrod went to help the duke Richard I of Normandy, who was afraid of a possible invasion by the Carolingian king Lothar I of France. Once the Franks had been defeated, the fleet of Gunrod stayed in Normandy, becoming a threat for Richard, so, the Norman duke sent the Norsemen to another place by telling them about the existence of an important pilgrimage site in the north of Hispania, Santiago de Compostela, where they could pillage a huge treasure. The fleet of Gunrod reached Galicia the same year. They crushed the Galician army, and then entered and sacked the city of Santiago de Compostela. Three years after the sack of Santiago de Compostela, Gunrod attacked Galicia again, only to find a powerful army sent to put an end to the Viking expedition.
