For those of us who spend our weekends squinting through loupes at the “Soldiers with Standards” (GLORIA EXERCITVS) bronze reverses, the coinage of the house of Constantine offers a masterclass in dynastic propaganda. But among the sons of the Great Reformer, Flavius Claudius Constantinus, known to history as Constantine II, remains a figure of tragic ambition—a prince who held the gold of an empire in his hands but could never quite grasp his father’s lightning.

A Caesar in the Cradle

Born in Arelate (modern-day Arles, France) in 316 AD, Constantine II was the eldest son of Constantine the Great and Fausta. His pedigree was a numismatist’s dream: the grandson of both Constantius Chlorus and the Emperor Maximian. In the ancient world, power was often minted before it was wielded. By 317 AD, at the tender age of one, his father raised him to the rank of Caesar.

If you look at the coinage from this period, you’ll find small bronze pieces—nummi—featuring a tiny, stylized bust of a child. These weren’t just coins; they were “coming soon” posters for the next generation of the Constantinian dynasty. Even as a boy, he was sent to the Rhine frontier to “oversee” the defense of the empire, a move designed to soak his image in military prestige.

The Great Division: 337 AD

The death of Constantine the Great in 337 AD triggered one of the most ruthless “succession plans” in Roman history. To ensure the throne stayed within the immediate family, many of Constantine II’s cousins and uncles were purged in a series of palace massacres. When the dust settled, the empire was carved into three pieces like a funeral cake among the surviving brothers:

• Constantine II: The West (Gaul, Britain, and Spain).
• Constantius II: The East (from the Balkans to Egypt).
• Constans: The Middle (Italy, Africa, and Illyricum).

As the eldest, Constantine II felt he was the rightful “senior” Augustus. He viewed himself as a mentor to his younger brother Constans, who was still a teenager. However, in the world of Roman politics, “mentorship” was often a polite word for “vassalage.”

Numismatic Messaging: The Struggle for Superiority

During his short three-year reign as Augustus (337–340 AD), Constantine II’s coinage reflects a desperate need for legitimacy. He continued his father’s tradition of high-quality bronze and gold, but the imagery shifted. You see a heavy emphasis on the VIRTVS EXERCITVS (The Valor of the Army) and VICTORIA AVGG (The Victory of the Augusti).

For a collector, identifying a Constantine II can be a bit of a riddle. Because his name is so similar to his father’s, we look for the “Junior” indicators or the specific titles. On many of his coins, he is depicted holding a phoenix on a globe—a symbol of the “Eternal Rome” he hoped to lead. Yet, the phoenix was an ironic choice for a man whose reign would end in ashes so quickly.

The Road to Aquileia: A Brother’s Betrayal

The tension between the brothers reached a breaking point over the control of Italy and North Africa. Constantine II believed his share of the empire was insufficient for the firstborn. He demanded territory from Constans, who was proving to be a more capable and independent ruler than expected.

In 340 AD, while Constans was preoccupied with the frontiers in Dacia, Constantine II saw his opening. He led a seasoned army across the Alps, descending into Italy like a storm. He hoped for a swift coup that would grant him the heart of the Roman world.

He didn’t realize that Constans had already dispatched a vanguard of elite troops to intercept him. Near the city of Aquileia, the two forces clashed. In a skirmish that history remembers as more of a desperate scramble than a grand tactical masterpiece, Constantine II was lured into an ambush. He was cut down and his body reportedly thrown into the river Alsa. He was only 24 years old.

The Rarity of a Fallen Augustus

Because he ruled as a senior Augustus for only three years, Constantine II’s independent issues are significantly scarcer than those of his longer-lived brothers. Once he was killed, his name was often subjected to damnatio memoriae—a symbolic “erasing” from history—though this was less severe than with other emperors because his brothers still held the throne.

Collectors often hunt for his Arles mint issues, a nod to his birthplace. These coins are the remnants of a man who tried to be his father but lacked the patience to let his own legend grow. He remains a cautionary tale in the annals of history: the prince who had the lineage, the legions, and the mints, but lacked the one thing every emperor needs to survive—the favor of the Fates.
