Saxon Wars
The Saxon Wars were the campaigns and insurrections of the thirty-three years from 772, when Charlemagne first entered Saxony with the intent to conquer, to 804, when the last rebellion of tribesmen was defeated. In all, 18 campaigns were fought, primarily in what is now northern Germany. They resulted in the incorporation of Saxony into the Frankish realm and their forcible conversion from Germanic paganism to Christianity.
