Battle of Lugdunum
Rome's bloodiest battle between its own armies
Near the city of Lugdunum, modern-day Lyon, Emperor Septimius Severus clashed with the usurper Clodius Albinus in the bloodiest battle ever fought between Roman armies. Tens of thousands of soldiers fell on both sides before Severus emerged victorious. The defeat of Albinus secured Severus's grip on the empire but left a trail of devastation across Gaul, demonstrating the terrifying cost of Rome's internal power struggles.
