Attila had been sole ruler of the Hunnic empire since 445 CE, after the murder of his older brother Bleda. The Hunnic confederation under his rule covered most of central and eastern Europe — from the Rhine to the steppes of modern Ukraine. He had received heavy annual tribute from both the Eastern Roman Empire at Constantinople and the Western Roman Empire at Ravenna, and had conducted two major invasions of the Western Empire in 451 (defeated at the Battle of the Catalaunian Fields) and 452 (a campaign in northern Italy that withdrew after meeting Pope Leo I outside Mantua).

In early 453 CE Attila married a young Germanic-Gothic woman named Ildico. She is otherwise unknown. The wedding was held at his principal camp on the Hungarian Plain.

The morning

The accounts of the death come from two sources. The first is the contemporary Roman diplomat Priscus of Panium, who had visited Attila’s court in 449 CE and had personal informants in the Hunnic administration. Priscus’s account survives only in fragments quoted by later historians. The second is Jordanes writing about a century later in his Getica, drawing on a lost work by Cassiodorus that itself drew on Priscus.

The narrative is consistent across both sources. Attila had drunk heavily at the wedding feast. He retired to the bridal pavilion with Ildico late at night. The Hunnic court attendants waited outside through the night and the following morning. When Attila did not emerge by midday, the attendants forced the door.

They found Attila lying on his back on the bed. Blood had run from his nose and pooled in his throat and chest. He had drowned in his own nasal haemorrhage during drunken sleep. Ildico was sitting on the floor by the bed, weeping, with her veil drawn over her face.

She was not harmed. The court physicians who examined the body found no wound and no obvious sign of poisoning.

Whether it was poison

The conventional ancient account is accidental. A heavy drinker, in his late fifties, with an existing condition of recurrent nosebleeds (which Priscus mentions had been a chronic complaint of Attila’s for years), dies after a heavy night of wedding drinking. The cause of death is consistent with alcohol-induced oesophageal varices haemorrhaging or with a ruptured nasal-pharyngeal vessel during deep sleep.

The poisoning alternative is suggested by some later medieval sources — most notably the Old Norse Atlakviða, which depicts Ildico as a Germanic princess who murders Attila to avenge her family. The Atlakviða version is, however, a legendary reconstruction from approximately 600 years later, with no contemporary independent support.

A third possible reading — favoured by a small number of modern medical historians — is that Attila died of an oesophageal varix rupture induced by liver cirrhosis. Heavy drinking from a young age can produce cirrhosis with portal hypertension; the portal hypertension produces fragile dilated veins at the oesophageal-gastric junction; a rupture during sleep can produce exactly the pattern of death by exsanguination via the upper airway that Priscus describes.

None of the three readings can now be confirmed.

What followed

Attila was buried in a triple coffin of iron, silver, and gold, in a riverbed that the Hunnic engineers temporarily diverted for the burial and then returned to its original course to conceal the grave. The slaves who had dug the grave were killed to prevent disclosure. The location has never been identified.

The Hunnic empire collapsed within months. Attila’s sons Ellac, Dengizich, and Ernak quarrelled over the succession. A revolt of the subject Germanic peoples — Gepids, Ostrogoths, Rugii, and others — under the Gepid king Ardaric defeated the Hunnic core army at the Battle of Nedao in 454 CE. The Huns lost their European position within a generation.

The Eastern Roman Empire stopped paying tribute. The Western Roman Empire survived for another 22 years before its own collapse in 476 CE.

A Hungarian shepherd reported in 1898 having found a heavy silver coffin while ploughing near the Tisza River. The discovery was not corroborated by any subsequent excavation. No Attila grave has ever been recovered.
