In 680, Aldgisl died and was succeeded by his son Radbod, king of the Frisians. While Aldgisl, had welcomed Christianity into his realm, Radbod attempted to extirpate the religion and free the Frisians from subjugation to the Merovingian kingdom of the Franks. In 689, however, Radbod was defeated by Pepin of Herstal in the battle of Dorestad and compelled to cede Frisia Citerior (Nearer Frisia, from the Scheldt to the Vlie) to the Franks.
