Royal Frankish Annals
The Massacre of Verden was an event during the Saxon Wars where the Frankish king Charlemagne ordered the death of 4,500 Saxons in October 782. Charlemagne claimed suzerainty over Saxony and in 772 destroyed the Irminsul, an important object in Saxon paganism, during his intermittent thirty-year campaign to Christianize the Saxons. The massacre occurred in Verden in what is now Lower Saxony, Germany. The event is attested in contemporary Frankish sources, including the "Royal Frankish Annals".
