During the Gallic Wars (58–50 BC), the Mediomatrici sent 5,000 men to support Vercingetorix who was besieged in Alesia in 52. In 69–70 of the Common Era, their capital Divodurum was sacked by the armies of Vitellius, and 4,000 of its inhabitants massacred. The Romanization of the Metromatrici was apparently slower compared to their neighbours the Treviri.
