Relations with Thracians

Since the writings of Herodotus in the 5th century BC, Getae/Dacians are acknowledged as belonging to the Thracian sphere of influence. Despite this, they are distinguished from other Thracians by particularities of religion and custom. Geto-Dacians and Thracians were kin people but they were not the same. The differences from the southern Thracians or from the neighbouring Scythians were probably faint, as several ancient authors make confusions of identification with both groups. Linguist Vladimir Georgiev says that based on the absence of toponyms ending in dava in Southern Bulgaria, the Moesians and Dacians (or as he calls them Daco-Mysians) couldn't be related to the Thracians.

In the 19th century, Tomaschek considered a close affinity between the Besso-Thracians and Getae-Dacians, an original kinship of both people with Iranian peoples. They are Aryan tribes, several centuries before Scolotes of the Pont and Sauromatae left the Aryan homeland and settled in the Carpathian chain, in the Haemus (Balkan) and Rhodope mountains. The Besso-Thracians and Getae-Dacians separated very early from Aryans, since their language still maintains roots that are missing from Iranian and it shows non-Iranian phonetic characteristics (i.e. replacing the Iranian "l" with "r").
