Medieval cultural group from what is now Northern Germany
The Saxons, sometimes called the Old Saxons or Continental 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. Many of their neighbours were, like them, speakers of West Germanic dialects, including the inland Franks and Thuringians to the south, and the coastal Frisians and Angles to the north who were among the peoples who were originally referred to as "Saxons" in the context of early raiding and settlements in Roman Britain and Gaul.
