The Allobroges: On the Threshold of the Roman World

History & Finds The Allobroges: On the Threshold of the Roman World placeholder

The Allobroges were a Celtic people in the south-east of Gaul, between the Rhône, Isère and the Alps, in the area around Vienne and later Geneva.

Early subjugation

As early as 121 BC – long before Caesar – the Allobroges were subdued by Rome and incorporated into the province of Gallia Narbonensis. They were thus among the first Gauls under Roman rule.

The Catiline conspiracy

In 63 BC Allobrogian envoys played a surprising role in Rome: the conspirators around Catiline tried to win them as allies. The Allobroges reported it to the authorities – and gave Cicero the evidence that brought the conspiracy down. Later they themselves rose against Rome's harsh administration, but were put down.

"The Allobroges, subdued only shortly before, were not yet well disposed to Rome."after Caesar, The Gallic War I (public domain, own translation)
What is documented: The subjugation in 121 BC, the membership of the province of Narbonensis, the role of the Allobrogian envoys in the Catiline conspiracy of 63 BC (Cicero, Sallust) and their later revolt.
What is interpretation: Why the Allobroges betrayed the conspirators – out of loyalty or cool calculation – is interpretation; the sources (Cicero, Sallust) are Roman and partisan. About their Celtic culture before Rome we know little directly.

The Allobroges stand at the transition from the Celtic to the Roman world. Continue with the Helvetii and Aedui.
