paragraph_text: Wars with the Danes
  
  Scandinavia had been brought into contact with the Frankish world through Charlemagne's wars with the Saxons. Raids on Charlemagne's lands by the Danes began around 800. Charlemagne engaged in his final campaign in Saxony in 804, seizing Saxon territory east of the Elbe, removing its Saxon population, and giving the land to his Obotrite allies. The Danish king Gudfred, uneasy at the extension of Frankish power, offered to meet with Charlemagne to arrange peace and (possibly) hand over Saxons who had fled to him; the talks were unsuccessful.
  
  The northern frontier was quiet until 808, when Gudfred and some allied Slavic tribes led an incursion into the Obotrite lands and extracted tribute from over half the territory. Charles the Younger led an army across the Elbe in response, but only attacked some of Gudfred's Slavic allies. Gudfred again attempted diplomatic overtures in 809, but no peace was apparently made. Danish pirates raided Frisia in 810, although it is uncertain if they were connected to Gudfred. Charlemagne sent an army to secure Frisia while he led a force against Gudfred, who had reportedly challenged the emperor to face him in battle. The battle never took place, since Gudfred was murdered by two of his own men before Charlemagne's arrival. Gudfred's nephew and successor Hemming immediately sued for peace, and a commission led by Charlemagne's cousin Wala reached a settlement with the Danes in 811. The Danes did not pose a threat for the remainder of Charlemagne's reign, but the effects of this war and their earlier expansion in Saxony helped set the stage for the intense Viking raids across Europe later in the ninth century.
