Haithabu , centrally located on the Jutland Peninsula had been a Frisian and Saxon trading place. In 808 Charlemagne placed Abodrites on south eastern Jutland and the Baltic Sea, removing Saxons, who opposed Charlemagne's Frankish Christianization attempts. The trading center was named Hedeby by the Danes , who then took over.
Franks, Jutes, Frisians, Saxons, Slavs traded there until it was destroyed by Vikings ,who destroyed other towns, such as Hamburg and Jomsburg.
