Byzantine-Lite: The Empire of Trebizond under the Komnenos Dynasty

Economics and society,, Inter-ethnic relations, International Relations, Medieval history,, Regional History

We all know of the great empires of history, the names roll off the tongue easily—Roman, Byzantine, British, Spanish, Chinese, Mongol, Persian, Alexander the Great, Ottoman, etc—we’ve read the history texts at school and seen countless historically bastardised film interpretations, but what of the myriad of little and little known and often ephemeral (small “e”) empires of the distant past? Not so familiar. I’ve always marvelled at the idea of these lesser, obscure imperial entities and been intrigued by how they managed to exist (and persist) at all side by side with the aforementioned “big boys”, the powerful and by definition expansive empires🄰.

Byzantine’s successor states: Take for instance the Trapezuntine Empire, more commonly called the Empire of Trebizond…who outside of the learned medievalist has ever heard of it, let alone be confident of pinpointing its location on any world atlas? Time to fill in a few gaps in the general knowledge caper. Imperial Trebizond consisted mainly of several small portions of land in the region known as the Pontus on the southern shores of the Black Sea🄱. The “empire” had its origins in the sack of Constantinople and dissolution of the Byzantine Empire by crusaders of the Fourth Crusade in 1204. Byzantine’s eclipse provided the opportunity for the creation of five new rump states from its existing territory – what became the empires of Trebizond, Nicaea and Thessalonica and the despotates of Morea and Epirus.

This didn’t happen by osmosis, in the case of Trebizond the empire came about when the Komnenos brothers (Alexios and David), descended royally from Komnenian Byzantine emperors, seized Trebizond and the surrounding province of Chaldia with the military support of their formidible relative, Queen Tamar of Georgia. The elder brother had himself crowned emperor of Trebizond (Alexios I)🄲. Emperor Alexios, styling himself Megas Komnenos🄳, also laid claim to the Byzantine throne however the Trebizond rulers lost out to the more militarily accomplished Nicene Empire in that contest. Michael VIII Palaiologos of Nicaea became emperor of the restored Byzantine Empire (aka Latin Empire) in 1261 and the Palaiologan Dynasty ran the empire right up to Constantinople’ fall to the Ottomans in 1453.

A nominal “empire: Trebizond was something of an outlier when it comes to classic empire material…for a start, aside from acquiring Erzurum to its south in the early 14th century and the coastal enclave of Sinope in eastern Anatolia🄴, there was no expansive growth as we saw with ancient Rome and Great Britain, the Pontus-based “empire” failed abjectly to expand its borders in any lasting way. Nor was it an empire with a conglomerate structure (or if you like, the necessary political configuration), ie, a situation where a dominant central power controls peripheral (outer) client states or colonies, Trebizond acquired no vassal states to speak of subordinate to its power [“A Glossary of Political Economy Terms: Empire”, (Auburn University), www.auburn.edu/]. It lacked the military force to realise these goals by conquest. In short the Trapezuntine Empire was an empire in name only🄵.

Last Greek empire standing: The only really stand-out achievement of the Trebizond Empire was its staying power. Despite its disadvantages —positioned within the sphere of influence of more powerful states such as the Seljuk Turks; the destabilising roles of Genoa and Venice; the decimation of the Black Death; the instability of civil war (which allowed the Genoese and Turks to further encroach territorially on a weakened Trebizond)—the empire survived for so long, from its founding in 1204 to its ultimate conquest by the Ottomans under Sultan Mehmet II in 1461—257 years, 22 emperors (including two empresses)—even outlasting the supposedly impregnable Constantinople which fell in 1453, as well as outliving the other Byzantine successor states in the region🄶. For this reason imperial Trebizond is sometimes called the last “Greek empire”.

Scholars point to a number of factors contributing to the empire’s surprising longevity. One is a favourable geographical location, the Pontiac Mountains behind Trebizond provide an advantageous natural barrier to invaders with designs on the mini-state. The capital city of Trebizond, built to resemble a kind of “mini-Constantinople” complete with imitation Hagia Sophia church, was further protected by the erection of impressively strong walls and fortifications [‘Trebizond’, The Byzantine Legacy, www.thebyzantinelegacy.com].

The inestimable value of Mongol patronage and strategic alliances: But above all else what permitted Trezibond to continue to survive in such a turbulent world was its commercial importance, and what permitted its commerce to thrive was the expansion west and southwards of the all-conquering Mongol Empire. The Mongols’ capture of Baghdad and the eclipse of the Abbasid Caliphate in 1258 resulted in the terminus of the lucrative Silk Road being diverted to Trebizond, making the city-state a funnel between east and west trade and enriching the small empire [Michael Goodyear, ‘Empire of Trebizond’, 21-May-2019, World History Encyclopedia, www.worldhistory.org]. The other critical practice to preserve Trebizond’s independence was marriage diplomacy, of which the Komnenian rulers were very adept. Trebizond rulers formed alliances with rivals, defusing potential threats to the empire by arranging the marriage of many of its (beautiful) princesses to the Byzantine royalty and to Black Sheep and White Sheep Turkomen (nomadic Turkish confederations) (Goodyear).

Trebizond continued to pay tribute to the Mongols as a vassal state which guaranteed its continued protection under the all-powerful Turco-Mongol warlord Tamerlane (or Timur), but once he departed the scene (beginning of the 15th century) and Mongol power waned, the Ottoman Turks re-emerged as the greatest danger to the tiny empire’s survival.

Endgame for Megas Komnenos: The tipping point for the Ottomans to decisively move on Trebizond seems to be Emperor David Komnenos’ intrigues with European powers with the purpose of launching a new crusade against the Ottoman Empire. Mehmet II laid seize to Trebizond in 1461 and after a concerted sea and land blockage, it compelled David, bereft of any sign of relief from his Christian allies, to surrender the citadel-city almost without a single sword needing to be drawn in anger. The fall of Trebizond, the final Greek outpost, as one historian noted, also extinguished the last vestiges of the Roman Empire, nearly 1,500 years after its beginnings [Donald M. Nicol, The Last Centuries of Byzantium, 1261–1453, (1993, 2nd edition].

Postscript: Trebizond under the Ottomans became the modern city of Trabzon, which during WWI was captured by the Russians. Interestingly, following the war a proposition was made at the Paris Peace Conference for an independent Pontiac Greek state (the would-be “Republic of Pontus”) including Trabzon and most of the post-Trebizond space. While the key figure at the talks US President Wilson supported its creation, the Greek prime minster didn’t, fearing the mini-state would be too vulnerable to withstand any Turkish attempt to absorb it, and the proposition was lost.

🄰 of course the reality was that most of them didn’t persist for long

🄱 plus several even smaller enclaves on the Crimean Peninsula

🄲 his brother, David, became commander of the state’s imperial army

🄳 Megas means “great” or “grand”. After 1282 Komnenian emperors added basileus and autokrator to their list of royal titles

🄴 the Komnenos emperors managed to lose Sinope twice, the first time to the Nicene Empire and the second time for keeps, to the Sultanate of Rum

🄵 although it did meet some of the criteria for an empire, it had a flourishing commerce and wealth (mainly from its silver mines) and it possessed an entrenched ruling class

🄶 the fate of Theodoro (it’s Crimean enclaves) managed to be postponed even longer than that of Trebizond, they were not absorbed into the Ottoman Empire until 1475
