Britannia Superior
Britannia Superior (Latin for "Upper Britain") was a province of Roman Britain created after the civil war between Septimius Severus and Clodius Albinus. Although Herodian credits Severus with dividing Roman Britain into the Northern territory of Britannia Inferior and the Southern territory of Britannia Superior, modern scholarship argues that it is more likely that Caracalla was the person who made the split sometime in the early 3rd century CE. The previous British capital Londinium remained the centre of Britannia Superior while Eboracum, or modern York was the capital of Britannia Inferior.
