Agallianos Kontoskeles, Byzantine commander and rebel leader

Agallianos Kontoskeles (Greek: Ἀγαλλιανός Κοντοσκέλης), a name that echoes from the annals of the early 8th century, was a significant figure in Byzantine history, remembered primarily as a military commander who rose to lead a formidable rebellion. His life concluded dramatically on April 18, 727, amidst the tumultuous political and religious landscape of the Byzantine Empire.

A Byzantine Commander in Turbulent Times

Serving the Byzantine state, Agallianos held the distinguished military rank of tourmarches within the Theme of Hellas during the years 726 and 727. The tourma was a major subdivision of a Byzantine theme, meaning he commanded a considerable military force within this vital administrative and military district encompassing much of mainland Greece. It was precisely during this period that the Theme of Hellas erupted into open revolt against the reigning emperor, Leo III the Isaurian.

This uprising occurred at a particularly sensitive moment in Byzantine history, coinciding with the early years of Emperor Leo III's controversial iconoclastic policies. While the primary motivations for this specific rebellion might have been multifaceted, including regional grievances or political ambition, the broader atmosphere was certainly charged with religious tension and dissent against imperial authority emanating from Constantinople.

Leadership of the Rebellion

Agallianos Kontoskeles quickly emerged as a central figure, taking on the mantle of leadership for this significant revolt. He was not alone in this ambitious endeavor; he was joined by Stephen, who is believed to have been the commander of the Karabisianoi naval district of the Cyclades. The Karabisianoi represented an early and powerful naval organization responsible for maritime defense and operations, particularly in the Aegean Sea. Their combined leadership signaled a potent threat, marrying land-based military power with significant naval capabilities.

The rebels, fueled by their opposition to Emperor Leo III, took the audacious step of proclaiming their own emperor: a certain Kosmas. This act was a direct challenge to imperial legitimacy and effectively escalated the rebellion from a regional uprising to a full-blown civil conflict with aspirations for the imperial throne itself. Such acclamations were not uncommon in Byzantine history, reflecting the volatile nature of imperial succession and the powerful influence of the military.

The Fateful Naval Encounter

The climactic confrontation between the rebel forces and the loyalist navy unfolded on April 18, 727. The stakes were incredibly high, with the future of the empire potentially hanging in the balance. Despite the rebel fleet's strength, it ultimately met a decisive defeat at the hands of the imperial loyalists. The turning point in this naval battle was the deployment of one of Byzantium's most feared and iconic secret weapons: Greek fire.

Greek fire, an incendiary weapon whose precise composition remains a mystery to this day, was capable of burning ferociously even on water, instilling terror in enemy ranks and proving devastatingly effective in naval engagements. Its use by the loyalist navy underscored their technological superiority and likely played a crucial role in breaking the rebel's resolve and destroying their fleet.

The Tragic End of the Leaders

The defeat spelled a swift and brutal end for the rebellion's leaders. Agallianos Kontoskeles met a dramatic and tragic fate. According to historical accounts, he fell from the deck of his ship into the churning sea while still encased in his full armor, leading to his drowning on that fateful day of April 18, 727. His heavy armor, designed for protection in battle, ironically became his undoing in the waters of the Aegean.

His co-conspirators faced an equally grim, if different, end. Stephen and the proclaimed emperor Kosmas were captured by the victorious loyalist forces. In line with the harsh justice of the era for those who dared to challenge imperial authority, they were summarily beheaded, serving as a stark warning against future insurrections.

A Historical Misattribution: The Kontoskeles Surname

Adding a curious footnote to his story, Agallianos's distinctive surname, "Kontoskeles" (Greek: Κοντοσκέλης), meaning "short-leg" or "stumpy-leg," led to a notable historical misattribution. The Patria of Constantinople, a collection of Byzantine texts providing historical and topographical details about the city, erroneously linked him to the construction of the Kontoskalion harbour in Constantinople.

This misidentification is a classic example of how popular etymology can lead to historical inaccuracies, where a linguistic similarity is mistaken for a causal connection. The Kontoskalion harbour, a vital port facility in the Byzantine capital, had its own long and significant history, unrelated to Agallianos Kontoskeles despite the similarity in names. This anecdote highlights the challenges and sometimes amusing pitfalls in reconstructing historical narratives from fragmented sources.
