Corded Ware culture
The Nordic Bronze Age is a successor of the Corded Ware culture in southern Scandinavia and Northern Germany. It appears to represent a fusion of elements from the Corded Ware culture and the preceding Pitted Ware culture. The decisive factor that triggered the change from the Chalcolithic Battle Axe culture into the Nordic Bronze Age is often believed to have been metallurgical influence as well as general cultural influence from central Europe, similar in custom to those of the Unetice culture.
