They are mentioned as Bituriges by Caesar (mid-1st c. BC), as Bitoúriges oi? Kou?boi (? ) and Koúbois Bitoúrixi (? ) by Strabo (early 1st c. AD), as Bituriges ... qui Cubi appellantur by Pliny (1st c. AD), and as Bitoúriges oi? Kou?boi (? ) by Ptolemy (2nd c. AD).
The city of Bourges, attested as civitas Biturigum ca. 400 CE ('civitas of the Bituriges', Bituricas in 844, Bituris in 1182), and the region of Berry, attested as pagus Biturigus in 860 ('pagus of the Bituriges'), are named after the Gallic tribe.
Early in the 1st century BCE, they had been one of the main Gallic tribes, especially in terms of druids and their political influence. But they soon declined in power as the druids were an important target for Julius Caesar in his conquest of Gaul. What is more, the fact that Avaricum (Bourges) was the only Celtic city that Vercingetorix did not burn, contrary to his scorched earth strategy, upon the approach of Caesar's legions is another proof of the political importance of the Bituriges. Eventually, the town was to be buried by the Roman legions.
Besides Avaricum or Mediolanum (Châteaumeillant) on the road from Paris and Orléans to Arvernum (Clermont-Ferrand), Argentomagus (Saint-Marcel near today's Argenton-sur-Creuse), Déols (vicus Dolensi or Dolus in the 6th c.) or Levroux on the road from Toulouse to Paris were other oppidums of the Bituriges.
