Widukind

Widukind, also known as Wittekind and Wittikund, was a leader of the Saxons and the chief opponent of the Frankish king Charlemagne during the Saxon Wars from 777 to 785. Charlemagne ultimately prevailed, organized Saxony as a Frankish province, massacred thousands of Saxon nobles, and ordered conversions of the pagan Saxons to Christianity. In later times, Widukind became a symbol of Saxon independence and a figure of legend. He is also venerated as a Blessed in the Catholic Church.
