With their victory in the Battle of Norditi in 884 they were able to drive the Vikings permanently out of East Frisia, although it remained under constant threat. When, around 800, the Scandinavian Vikings first attacked Frisia, which was still under Carolingian rule, the Frisians were released from military service on foreign territory in order to be able to defend themselves against the Vikings. The freedom of the Frisians developed in the context of ongoing disputes over the rights of local nobility.

During the period of Frisian freedom the area did not have a sovereign lord who owned and administered the land. Historical Frisia included the modern provinces of Friesland and Groningen, and the area of West Friesland, in the Netherlands, and East Friesland in Germany. Friese Freedom or Freedom of the Frisians ( West Frisian: Fryske Frijheid Dutch: Friese Vrijheid German: Friesische Freiheit) was the absence of feudalism and serfdom in Frisia, the area that was originally inhabited by the Frisians.
