1911 Encyclopædia Britannica/Allobroges
ALLOBROGES (in Gr. usually Άλλόβριγες), a Celtic tribe in the north of Gallia Narbonensis, inhabiting the low ground called the “island” between the Rhodanus, the Isara and the Graian Alps, corresponding to the modern Dauphiné and Savoy. If the name is rightly interpreted as meaning “ aliens, ” they would seem to have driven out the original inhabitants. Their chief towns were Vienna (Vienne), Genava (Geneva) and Cularo (afterwards Gratianopolis, whence Grenoble). The Allobroges first occur in history as taking part with Hannibal in the invasion of Italy. After the subjugation of the Salluvii (Salyes) by the Romans in 123 B.C., having given shelter to their king Tutomotulus and refused to surrender him, the Allobroges were attacked and finally defeated (August 8, 121) at the junction of the Rhodanus and Isara by Q. Fabius Maximus (afterwards Allobrogicus). But they still remained hostile to Rome, as is shown by the conduct of their ambassadors in the Catilinarian conspiracy (63; see Catiline); two years later a revolt under Catugnatus was put down by Gaius Pomptinus at Solonium. Under Augustus they were included in Gallia Narbonensis; later, in the Viennensis.
