In ancient times, the incorporated territory of Albania was historically inhabited by Indo-European peoples, among them numerous Illyrian tribes, Ancient Greeks and Thracians. In view of the Illyrian tribes, there is no evidence that these tribes used any collective nomenclature for themselves, while it is regarded to be unlikely that they used a common endonym. The endonym ''Illyrians'' seems to be the name applied to a specific Illyrian tribe, which was the first to come in liaison with the Ancient Greeks resulting in the endonym ''Illyrians'' to be applied ''pars pro toto'' to all people of similar language and customs.
