Constantius Chlorus

Photograph at the Constantius Chlorus black plaque

Constantius I is remembered for his significant military career, rising from humble beginnings to become a Roman emperor. He was a founding member of the Tetrarchy, serving as Caesar before his elevation to Augustus. His imperial rule saw him assigned to govern Gaul, where he achieved notable victories against usurpers in Britain and campaigned vigorously along the Rhine frontier against Germanic tribes.

His reign also included an order for the demolition of churches during a period of imperial persecution, though he is not recorded as actively pursuing Christians. Following imperial reassignment, Constantius led a successful military action against the Picts. He died in Eboracum, modern-day York, during his tenure as senior emperor. It was in this city that his army subsequently proclaimed his son, Constantine, as emperor.
