Medieval cultural group from what is now Northern Germany
The Saxons, sometimes called the Old Saxons, were the Germanic people of early medieval "Old" Saxony (Latin: Antiqua Saxonia) which became a Carolingian "stem duchy" in 804, in what is now northern Germany. They were the northern neighbours of the Franks and Thuringians, and the eastern neighbours of the Frisians. The political history of these continental Saxons is unclear until the 8th century and the conflict between their semi-legendary hero Widukind and the Frankish emperor Charlemagne.
