 The Thracian stage is associated with the emergence of Thracian populations from the fusion of the local Chalcolithic stock with the incoming peoples of the transitional Indo-Europeanization Period.By the time of Bronze Age, and during the transitional period to the Iron Age, the cultures of this Carpathian area may be attributed to proto-Thracian and even Thracian populations—ancestors of the peoples known to Herodotus as the Agathyrsae and the Getae, and to the Romans as the Dacians (by Iron Age II).The culture of these nuclear groups were typified by military aristocracies.
