Ulpia Severina Coins: Empress of Aurelian and Rome’s Mysterious Interregnum
Ulpia Severina Coins: Empress of Aurelian and Rome’s Mysterious Interregnum
After Aurelian Was Murdered, Who Ruled Rome? Her Coins Are the Best Evidence We Have.
Ulpia Severina occupies one of the most intriguing places in the history of the Roman Empire.
She was the wife of Emperor Aurelian, the soldier-emperor who reunited a fractured Roman world in the third century AD. Yet Severina’s greatest historical mystery begins not during her husband’s victories, but after his assassination in AD 275.
For generations, historians and numismatists have asked an extraordinary question: did Ulpia Severina briefly rule the Roman Empire in her own right?
The surviving evidence does not allow us to answer that question with certainty. But Severina’s coins are central to the debate. They provide tangible evidence for her imperial status, her public image, and the political messages associated with the imperial household during the final months of Aurelian’s reign.
For collectors, that makes an Ulpia Severina coin more than a portrait of a Roman empress. It is a piece of evidence from one of the most mysterious transitions of power in Roman history.
Early Life and Rise of Ulpia Severina
Almost nothing certain is known about Severina’s life before she became empress.
Her full name is generally given as Ulpia Severina. The nomen Ulpia naturally recalls the family name of Emperor Trajan, Marcus Ulpius Traianus, but there is no secure evidence that Severina was descended from Trajan or belonged to his family. Her birthplace, parents, and early life are unknown.
This lack of biographical information is not unusual for third-century imperial women. The literary sources that survive from the period are incomplete, and Severina appears far more clearly in inscriptions and coins than she does in narrative histories.
Her historical importance therefore comes largely from her marriage to one of the most consequential emperors of the third century: Aurelian.
Marriage to Aurelian
Severina was married to Lucius Domitius Aurelianus, better known as Aurelian. The date of their marriage is uncertain, as are most details of their family life.
When Aurelian became emperor in AD 270, Rome was deep in the Crisis of the Third Century. Emperors rose and fell rapidly. Civil wars, invasions, economic disruption, and breakaway states threatened the survival of the empire.
Aurelian would spend the next five years changing that.
Aurelian’s Rise to the Imperial Throne
Aurelian came from the military world that increasingly dominated Roman politics in the third century. After the death of Claudius II Gothicus and the brief reign of Quintillus, Aurelian emerged as emperor in AD 270.
He inherited an empire that had effectively broken into three major political zones. Rome still controlled the central territories, but the Palmyrene Empire dominated much of the East under Zenobia and Vaballathus, while the Gallic Empire controlled large parts of the western provinces.
Aurelian defeated Palmyra, restored the eastern provinces, and then brought the Gallic Empire back under central control. These victories earned him the celebrated title Restitutor Orbis—Restorer of the World.
Severina’s elevation must be understood against this background of imperial restoration.

Severina as Augusta
Severina received the title Augusta, the female counterpart to Augustus and the highest imperial title normally granted to an emperor’s wife. Her coinage is generally associated especially with the later part of Aurelian’s reign, commonly placed around AD 274–275.
Her coins identify her clearly as SEVERINA AVG and present her with the carefully constructed visual language expected of a Roman empress.
Her portrait commonly shows a diademed and draped bust, often with an elaborate hairstyle. These were not merely decorative choices. Imperial portraits helped communicate hierarchy, legitimacy, continuity, and the stability of the ruling household.
That message was particularly important after years of civil war.
The Reign of Aurelian and the Reunification of Rome
By the time Severina’s coinage became prominent, Aurelian had achieved something remarkable. The Roman Empire was politically reunited.
He had defeated Zenobia’s Palmyrene regime, recovered the eastern provinces, ended the independent Gallic Empire, fought Germanic invaders, strengthened Rome’s defenses with the Aurelian Walls, and attempted to stabilize a badly damaged monetary system.
His reign also promoted the cult of Sol Invictus, the Unconquered Sun, as an important element of imperial religious ideology.
Yet Aurelian’s restored empire remained dependent on the emperor himself. There was no secure adult son waiting to inherit the throne. In that environment, Severina’s public status as Augusta carried political importance.
Severina’s Role at the Imperial Court
The exact political authority Severina exercised during Aurelian’s lifetime is unknown.
It would be easy to take the existence of her coins and turn her into a modern-style co-ruler, but the evidence does not justify that conclusion. Roman empresses frequently appeared on coinage without exercising independent sovereign authority.
What the coins do demonstrate is that Severina had become an officially recognized part of the imperial image presented to the Roman world.
Some of her reverse types emphasize harmony and concord—messages that carried obvious political significance after a decade of fragmentation.
The Assassination of Aurelian in AD 275
Aurelian’s reign ended abruptly in AD 275 while he was preparing for a campaign against the Sasanian Persian Empire.
According to the surviving literary tradition, a conspiracy developed among members of his staff after an official feared punishment and helped convince others that the emperor intended to execute them. Aurelian was assassinated near Byzantium.
His death created a dangerous problem: there was no obvious heir ready to assume power.
What happened between Aurelian’s death and the accession of Tacitus is one of the most debated episodes of the third century.
Did Ulpia Severina Rule Rome?
Possibly—but it should not be stated as established fact.
The idea that Severina briefly governed after Aurelian’s death has attracted considerable attention because some numismatic evidence has been interpreted as suggesting continued coin production in her name during the transition.
If Severina’s coinage continued after Aurelian died, it could indicate that the existing imperial administration used her authority or image to preserve continuity until a successor was established.
But there are major limits to what the evidence can prove.
Coins cannot by themselves demonstrate that Severina formally became sole Roman emperor, exercised all imperial powers, commanded the armies, or was recognized throughout the empire as an independent sovereign. Chronologies of individual issues and mints are also complex.
The safest historical conclusion is therefore more interesting than a simple yes or no: Severina may have played an important role in maintaining imperial continuity after Aurelian’s assassination, but an independent reign remains a hypothesis rather than a securely documented fact.
The Mysterious Interregnum of AD 275
Ancient literary sources describe an unusually long interval between Aurelian and Tacitus, sometimes portrayed as lasting many months while the army and Senate debated who should choose the next emperor.
Modern historians are cautious about taking that narrative literally. The chronology is uncertain, and the literary tradition may exaggerate both the duration and the Senate’s role.
That uncertainty is precisely why the coins matter.
Numismatic evidence can sometimes preserve information that narrative histories omit. Changes in mint production, titulature, portraiture, and reverse types can help reconstruct political transitions—but they must be interpreted carefully.
Severina stands at the center of that debate.
What Ulpia Severina’s Coins Tell Us
Severina’s coins establish several things with much greater confidence than the interregnum theory.
First, she was formally recognized as Augusta.
Second, her portrait and name were distributed through the Roman monetary system, giving her an empire-wide public identity.
Third, the themes chosen for her reverse types emphasized values useful to the restored regime: concord, divine favor, stability, and the unity of the imperial household.
For historians, these coins are primary sources. For collectors, they offer a direct connection to the final chapter of Aurelian’s extraordinary reign.
Major Ulpia Severina Coin Types
The denomination most collectors are likely to encounter is the antoninianus—often called an aurelianianus in the context of Aurelian’s reformed coinage.
Severina’s portrait appears on issues from multiple imperial mints. Common legends include forms such as SEVERINA AVG.
Reverse designs vary by mint and issue, but concord is particularly important in her coinage.

CONCORDIAE MILITVM and Imperial Legitimacy
One of the most historically interesting Severina reverse types invokes Concordia and the military.
Concordia represented harmony, agreement, and political unity. In a third-century empire where emperors depended heavily on the loyalty of the army, references to concord with the soldiers carried obvious significance.
These types should not automatically be treated as proof that Severina personally commanded the army after Aurelian’s death. They are better understood as part of the political vocabulary of the imperial regime.
Even so, their existence makes Severina’s coinage unusually compelling when studying the uncertain transition of AD 275.
Mints, Portraits and Denominations
Collectors can encounter Severina’s coinage from several Roman imperial mints, and the exact style varies considerably.
Different workshops produced different portraits, legends, field marks, and reverse combinations. This makes Severina an interesting ruler to collect by mint or type rather than simply acquiring a single example.
Her antoniniani are the most accessible entry point. Scarcer precious-metal issues also exist, but availability and price can differ dramatically by denomination, mint, condition, and rarity.
How Rare Are Ulpia Severina Coins?
Ulpia Severina is historically obscure, but her more common antoniniani are not necessarily prohibitively rare.
That combination is part of her appeal. A collector can own a genuine coin depicting one of the most mysterious women of the later Roman Empire without needing the budget required for many famous Roman rarities.
Scarcity varies significantly between individual types and mints, however. A common Severina antoninianus and a rare issue connected to the chronological debate surrounding AD 275 should not be treated as equivalent.
Collecting Ulpia Severina Coins Today
Severina is particularly attractive to collectors interested in:
- Roman empresses
- Aurelian and the Crisis of the Third Century
- Women in ancient history
- Roman imperial propaganda
- Coins associated with disputed historical events
- Building collections by Roman ruler
She also fits naturally into a collection of Aurelian’s age alongside coins of Aurelian, Zenobia, Vaballathus, Tetricus I, Tetricus II, and Tacitus.
What to Look for When Buying an Ulpia Severina Coin
Begin with the same fundamentals that apply to other ancient Roman coins: authenticity, attribution, surfaces, strike, centering, and how clearly the portrait and legends survive.
For a first Severina coin, a readable SEVERINA AVG legend and recognizable portrait make the historical connection especially satisfying.
Collectors interested in the interregnum question should go further. Exact mint attribution, officina marks, reverse legend, and the chronology assigned to the issue matter. Claims that a particular coin was definitely struck while Severina “ruled Rome” deserve especially careful scrutiny.
Legacy of Ulpia Severina
Ulpia Severina did not leave behind the kind of literary biography that survives for Livia, Agrippina the Younger, or Julia Domna.
Instead, much of her story survives in metal.
Her coins place her beside Aurelian at the end of one of the Roman Empire’s greatest recoveries. They show that she held the title Augusta and that the state considered her image important enough to reproduce across imperial coinage.
Then Aurelian was murdered, the succession became uncertain, and Severina’s coinage acquired an entirely new historical significance.
Whether she actually governed the empire for a brief period remains unresolved. That uncertainty should not diminish her story. It is the reason her coins are so valuable as historical evidence.
They allow collectors to hold a primary source from a moment when the Roman world had lost its emperor—and may have looked, at least temporarily, to his empress for continuity.
After Aurelian died, who was actually in charge of Rome? Her coins are the closest thing we have to an answer.
