Those who are familiar with the Emperors of Byzantium know they were often spoken of as “purple-born,” a phrase that has, understandably, sparked some wild representations of these powerful rulers of the Byzantine Empire over the centuries. This has led to the rather amusing notion that their royal blood turned violet.

However, this whole Byzantine fascination with the color has a more symbolic element and reveals ancient beliefs related to power, imperial legitimacy, and the theatricality that defined the Byzantine court.

The reality behind Byzantium’s “purple-born” claim

The Greek word “porphyrogennetos,” meaning “born in the purple,” was, in fact, a magnificent declaration of legitimacy within the ruling class of Byzantium and a grand statement of imperial supremacy against the commoners. To be “born in the purple,” so to say, one had to meet certain requirements. Namely, one had to be a child born within a particular, elegantly purple-adorned chamber (known in medieval Greek as the “Porphyra”) within the Great Palace of Constantinople.

Most importantly, that individual’s father had to be the reigning emperor of the time so that the child could claim the title of “purple-born.” Babies born under such circumstances had an exclusive birthing suite, quite literally covered in the most revered and highly expensive color of the ancient world—Tyrian purple. This was a symbolic stamp of true imperial lineage that cemented the future of the baby from the moment he was born.

The dye itself, painstakingly extracted from hundreds of thousands of Murex sea snails, was so ludicrously expensive at the time that its use was largely reserved exclusively for the imperial family. As the years went by and the tradition became more established, this became, quite simply, the unmistakable symbol of the Byzantine divine right to rule the entire empire. The tradition, which really started taking shape from the 8th century onwards, found its most famous figure in Emperor Constantine VII Porphyrogennetos in the 10th century, even though the pattern existed centuries prior.

This was the time when the Byzantines cemented the belief that imperial power was divinely derived and publicly confirmed from the very moment a future ruler drew his first breath within the purple chamber.

The symbolism of that “purple-born” title resonated far beyond the palace walls of Constantinople and became common knowledge in the Byzantine world, with the term surviving to this day, even though its meaning now carries a more negative connotation. In modern Greece, when a politician is referred to as “porphyrogenetos,” it means he or she was born into a family of the country’s elite, something that helped them achieve high-ranking positions without necessarily being worthy of them.

The meaning behind the tradition

For the Byzantines, the whole porphyrogenetos notion was an incredibly clever and strong way for the ruling class to legitimize their heirs, setting them apart from siblings born before their father’s ascent to the throne, or, even worse, from any would-be usurpers who might disturb the lineage and bring the Empire into chaos.

The meticulous rituals that surrounded Byzantine imperial births, along with every single aspect of court life, were carefully thought out and perfectly executed in an attempt to strengthen the emperor’s unparalleled authority.

It was also a way for Byzantium to project a sense of continuity for the empire, even when political storms raged outside. This incredible attention to symbolism and presentation allowed Byzantium to project an image of strength, power, and stability—an influence that subtly entered the courts of later European monarchies and their own, often elaborate, claims to divine right (see for example, the British royal family of today).

The very notion of hereditary rule, which remains so central to many of today’s monarchies throughout the globe, clearly has its roots in these Byzantine practices, where lineage and the precise circumstances of one’s birth were absolutely crucial when it came to claims to the throne and the future of the empire.

Hence, while no royal blood ever actually turned purple, this persistent fascination among historians with this Byzantine concept really shows how important symbols and myths were in our understanding of power and history. That color purple, for instance, still carries strong regal connotations in countless cultures worldwide, similar to those of mighty Roman and Byzantine emperors.

More profoundly, the Byzantine obsession with legitimate succession, with the visible, ritualistic affirmation of authority, is still very present in many royal families across the world.
