The Brigianii (Gaulish: *Brigianioi) were a Gallic tribe dwelling around present-day Briançon during the Iron Age and the Roman period.
They are mentioned as Brigianii by Pliny (1st c. AD),[1] and as Brigiani, Brigantionis and Bricianiorum on inscriptions.
[5] Their territory was located north of the Caturiges, west of the Quariates, east of the Tricorii, south of the Segovii.
[6] Their chief town was known as Brigantio (modern Briançon), meaning 'eminence, high/elevated place' in Gaulish.
[5][7] They are mentioned by Pliny the Elder as one of the Alpine tribes conquered by Rome in 16–15 BC, and whose name was engraved on the Tropaeum Alpium.
