A Prince Born Into Empire

Constantine II was born in AD 316, likely in Arelate (modern Arles), during the early years of his father's rise to supreme power. He was raised during one of the most transformative periods in Roman history: Christianity expanding rapidly, civil wars reshaping the empire, Constantinople rising as a new imperial capital, and the imperial court becoming increasingly ceremonial and dynastic. In AD 317, while still a child, he was elevated to the rank of Caesar, officially making him heir to imperial authority.

Throughout his youth, Constantine II appeared prominently on imperial coinage. This was deliberate propaganda: coins served as political messaging, declarations of legitimacy, and reminders of dynastic continuity. As Caesar, he nominally governed Gaul, Britain, and Hispania, earned military prestige fighting Germanic tribes along the Rhine, and was continuously associated with imperial legitimacy through official portrait issues. Even as a teenager, his face circulated across the Roman world on bronze coinage.

When Constantine the Great died in AD 337, violence erupted almost immediately, a dynastic purge claimed several relatives and possible rivals. After the chaos settled, the three surviving brothers divided the empire. Constantine II received the western provinces: Britain, Gaul, and Hispania.

The Fall of Constantine II

Constantine II held seniority among the brothers due to his age, but believed he deserved even greater authority, particularly over the territories assigned to his younger brother Constans. Tensions escalated into open conflict. In AD 340, Constantine II invaded Italy in an attempt to overthrow Constans and consolidate the western empire under his sole control.

The campaign ended disastrously. Near Aquileia, he was ambushed and killed during the fighting, likely at only twenty-four years old. His reign as Augustus had lasted barely three years. Constans absorbed his territories.

Constantine II is often overshadowed by his father's legend and his brothers' longer reigns, but his life represents an important transitional moment: the rise of dynastic succession replacing earlier Roman traditions, imperial family politics becoming increasingly lethal, and the fragmentation of Constantine's legacy foreshadowing the repeated civil wars that would weaken the later empire.

Born into imperial power, raised as heir to the most important emperor since Augustus, and killed by his own brother before he turned twenty-five.

The Coinage of Constantine II

Most collectors encounter Constantine II through bronze issues struck both as Caesar under his father and as Augustus during his brief independent reign. Because enormous quantities of 4th century bronze coinage were produced, attractive examples remain accessible at very reasonable prices.

The GLORIA EXERCITVS reverse, two soldiers standing with military standards between them, is one of the defining coin types of the Constantinian dynasty. It appeared across the reigns of Constantine the Great, Constantine II, Constans, and Constantius II, making it an ideal type for building a dynasty set. The design reflected the reality of Constantinian rule: military loyalty was the foundation of everything. Collectors enjoy assembling examples from different mints and family members, comparing portrait styles, and tracing how the design evolved across the dynasty.
