Maxima Sequanorum

A long rivalry with the neighbouring Aedui over control of the Saône valley led the Sequani to call in the Germanic king Ariovistus, who then seized much of their territory and held it until Caesar defeated him in 58 BC. The episode broke the standing the Sequani had held among the peoples of eastern Gaul, and their lands passed under Roman control. Under the Empire the territory became a civitas with its capital at Vesontio and a second major town at Epomanduodurum (modern Mandeure). In Late Antiquity their territory gave its name to the frontier province of Maxima Sequanorum.
