Decius

Imperator Caesar Gaius Messius Quintus Traianus Decius Augustus

Reign 249 AD – 251 AD
Dynasty Crisis of Third Century
Born c. 201 AD
Died 251 AD

An Illyrian senator who defeated Philip the Arab, Decius adopted the name Traianus to invoke Rome's greatest military emperor. He launched the first systematic empire-wide persecution of Christians and became the first Roman emperor killed in battle against a foreign enemy when he fell fighting the Goths at Abritus.

Decius's death at Abritus shocked the Roman world and exposed the empire's vulnerability to barbarian invasion. His persecution of Christians and his numismatic honoring of the deified emperors both reflect a desperate attempt to restore traditional Roman values in a time of crisis.
