Redbad, the king of Frisians (c. 680- c. 719) was known in early medieval history for his contribution to keeping the ardent nature of the Frisian culture alive. He refused to convert to the new religion and fevered the followers of the pagan ways to revolt. During his reign, the enormous uprisings led to the dominion of the Frisian kingdom.
