Context

Having been appointed governor of the Roman province of Gallia Narbonensis (modern Provence) in 58 BC, Julius Caesar proceeded to conquer the Gallic tribes beyond over the next few years, maintaining control through a careful divide and rule strategy. He made use of the factionalism among the Gallic elites, favouring certain noblemen over others with political support and Roman luxuries such as wine. Attempts at revolt, such as that of Ambiorix in 54 BC, had secured only local support, but Vercingetorix, whose father, Celtillus, had been put to death by his own countrymen for seeking to rule all of Gaul, managed to unify the Gallic tribes against the Romans and adopted more current styles of warfare.
