Cause → Event → Consequence
Following the Year of the Five Emperors, multiple claimants contested control of the Roman Empire. Claudius Albinus, who had been recognized as Caesar by Severus, declared himself emperor and built a power base in Britain and Gaul, bringing the two rivals into direct military conflict.
On 19 February 197, the armies of Septimius Severus and Claudius Albinus clashed near Lugdunum in what ancient sources describe as the largest and bloodiest battle ever fought between Roman forces, with a combined total of approximately 150,000 soldiers engaged on both sides.
Severus won a decisive victory, killing Albinus and eliminating the last rival claimant to imperial power. This outcome consolidated Severus' sole rule over the Roman Empire and brought the prolonged succession crisis that had followed the death of Commodus to a definitive end.
