Septimius Severus. Roman emperor 193–211. Lucius Septimius Severus was born at Lepcis Magna in north Africa. Consul in 190, he was governor of Pannonia Superior on the Danube when he was proclaimed emperor on the assassination of Commodus, gaining the support of the Senate. He was opposed by the governor of Britain,
Clodius Albinus, whom he killed at the battle of Lyons in February 197. It may have been after this that the province and army of Britain were divided in two. After a series of wars against the Parthians, Severus' attention was drawn back to Britain by trouble with the Scottish tribes. He took the field with his sons
Caracalla and Geta in 208 and reconquered the Lowlands, establishing a garrison fortress at Carpow on the Tay. Increasing ill-health led to his death early in 211 at York.
