The Sogiontii lived in the middle valley of the Durance river, around present-day Sisteron (Segustero).[5] Their territory was located north of the Reii, west of the Bodiontici, east of the Vocontii, and south of the Sebaginni.[6]
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.[1]
