The Battle

History & Significance

When Constantius Chlorus died at Eboracum (York) in July 306 AD after his Pictish campaign, his son Constantine was immediately acclaimed Augustus by the British army — primarily by Alemannic auxiliaries under their king Crocus. The proclamation was technically irregular but the army loyalty carried it through. York became the birthplace of the man who would make Christianity the official religion of Rome.

Forces Involved

British garrison army and Alemannic auxiliary king Crocus with his warriors
