The Hallstatt culture was the predominant Central European culture from the 8th to 6th centuries BC (European Early Iron Age), developing out of the Urnfield culture of the 12th century BC (Late Bronze Age) and followed in much of Central Europe by the La Tène culture.
The Dacian Wars (101–102, 105–106) were two military campaigns fought between the Roman Empire and Dacia during Roman Emperor Trajan's rule. The conflicts were triggered by the constant Dacian threat on the Danubian Roman Province of Moesia and also by the increasing need for resources of the economy of the Roman Empire.
