The Vicissitudes of a Balkans Byzantine Successor State in the High Middle Ages: Despotate of Epirus and the Empire of Thessalonica

Biographical, Inter-ethnic relations, International Relations, Medieval history,, Regional History

The turmoil and political upheaval in the wake of the sacking of Constantinople by crusaders in 1204 fragmented the unity of the vast Byzantine Empire into a patch-quilt of separate parts. Epirus«𝕒», a region which encompassed parts of modern Greece, Albania, Bulgaria and northern Macedonia, formed itself into one of these independent states, known by modern historiographic convention as the Despotate of Epirus✴︎. Its founder and first despot was Michael I Komnenos Doukas (a member of the deposed Byzantine imperial house of Angelos) with the state’s capital initially (and mainly) situated at Árta in N.W. Greece. Michael’s reign saw some expansion by conquest into neighbouring Thessaly at the expense of the Lombard lords and for a brief time, control over the Lordship of Salona. Michael’s realm also became a refuge and centre of resistance for Greeks opposed to the intrusions of the Latin Crusaders [‘Michael I Komnenos Doukas’, Wikipedia, en.m.wikipedia.org].

Epirus imperial dreams – the Empire of Thessalonica: The Epirote State rulers soon found themselves embroiled in conflict with several of the other regional players, namely the other successor states, the Bulgarians (their former allies) and the Latins (Franks, Italians, etc). Michael I was assassinated in 1218 and replaced by his half-brother, Theodore Doukas, who extended the “empire” eastward, capturing Thessalonica from the Latins in 1224. Theodore duly established the “Empire of Thessalonica” and had himself crowned as emperor.

Battle of Klokotnitsa and aftermath: Theodore’s dream of ensconcing himself in Constantinople at the head of a greater Epirus-centred empire came crashing down at the Battle of Klokotnitsa in 1230. Theodore’s forces were attacked by both Bulgaria (under Tsar John Asen II) and the Nicene Empire (under John II Vatatzes) and comprehensively beaten. Theodore was captured, Bulgarian troops poured into Epirus and the despotate–cum–empire was reduced to vassal status vis-a-vís the Bulgarians. With Theodore imprisoned for seven years, the Epirote imperial leadership passed to his brother Manuel Komnenos Doukas, under whose reign the downslide continued, much of the earlier conquests in Macedonia and Thrace were lost. Meanwhile, in Epirus, Michael II, illegitimate son of the founder of Epirus Michael I, assumed control of a diminished Epirus and was recognised as despot (1230–ca.1267/1271). During Michael II’s rule the Epirote state was progressively reduced in size and power…in 1264 Michael was forced to recognise the suzerainty of Michael VIII Palaeologus whose rival successor state had ousted the Latins from Constantinople and restored the Byzantine Empire under the Nicene emperors.

Deposed Theodore returns as king-maker: In 1237 Theodore returned to Thessaloniki and deposed Manuel and installed his son John as emperor of Thessalonica. However, under pressure from the Nicaean Empire John was forced to abdicate in 1242 in favour of John III Vatatzes, the Nicaean emperor. In 1246 Thessalonica was lost to Nicaea for keeps. Over in Epirus Michael II was succeeded by his son Nikephoros I whose sovereign power was challenged by Charles I of Anjou and Sicily with whom he eventually entered into an alliance (Nikephoros acknowledged himself as Charles’ vassal). Later, Nikephoros allied himself with Charles’ son and successor Charles II, which led to conflict with the Byzantines.

Epirus’ fragile autonomy: Thomas I followed the same perilous path as his father Nikephoros after succeeding him in ca. 1297. Thomas clung precariously to power as Epirus lunged from alliance to conflict with both the Angevins and the Byzantines. Ultimately, Thomas was assassinated by his Italian-Greek nephew Nicholas Orsini, Count of Cephalonia (Ionian islands) in 1318. Nicholas, in control of southern Epirus, conspired with the Republic of Venice to retake the north including the city of Ioannina but was unsuccessful. In 1323 he was in turn usurped by his brother John II Orsini. The pattern of instability persisted…Epirus lost its independence to the Byzantine Empire in 1338 before briefly winning it back (with the assistance of Catherine I, Latin empress), only to lose it yet again to Byzantium, all within the space of two years. In 1348 it was the turn of the Serbs under (King) Stefan Dušan who incorporated Epirus and Thessaly into the Serbian Empire. After the Serbs came the Albanians…in 1367 the Despotate of Árta, an Albanian clan led by Pjetër Losha, attacked and besieged the Despotate of Epirus’ capital Ioannina.

Neapolitan ambitions for the Hellenes: Árta as a mainly autonomous despotate and then lordship persisted until 1416 when the incumbent despot’s rule was terminated by another Italian incursion. Neapolitan count, Carlo I Tocco (hereditary count palatine of Cephalonia and Zakynthos) took Arta as part of a systematic territorial expansion in Greece«𝕓». Carlo reached the limit of his expansion in the 1420s when the Byzantine emperor John VIII Palaiologos’ army cut short Carlo’s attempts to expand his influence into the Despotate of the Morea (the Peloponnese).

Epirus, the final chapter: Under Carlo I’s successor, Carlo II, the Tocco dynasty lost Ioannina in 1430 to the encroaching Ottoman conquest of Byzantine lands, as well as almost all of their possessions in Eripus by ca.1448«𝕔». At this time the fate of Epirus and the other post-1204 successor states of the Byzantine Empire had been well and truly sealed by an ongoing preoccupation with civil wars, conflict between themselves and religious disputes to the neglect of the greater threat posed by their common enemy from Asia Minor«𝕕».

Epirus, manoeuvring between east and west: Epirus, perched centrally between the east (Byzantium and Anatolia) and the west (western Europe), was in a special position, trying to carve its own niche in the region while competing for advantage and influence against the vested interests of more powerful players (namely Anjou, Venice, Sicily, Bulgaria, Serbia, Nicaea, Ottomans). The Epirote state’s despots through this era pursued two strategies for survival: it sought to protect its power base from its Latin enemies, while at the same time maintaining its independence from the rest of the Byzantine states. In a Byzantine world in which loyalty was a fluid commodity, Eripus found itself compelled by the power imbalances it faced to constantly swap its allegiances between the Latins and the Byzantines [Evangelos Zarkadas, ‘The Despotate of Epirus: A Brief Overview’, Mapping Eastern Europe, Eds: M.A. Rossi and A.I.

Postscript: Paucity of sources on Epirus Historians have long lamented the scarcity of surviving sources on Epirus, especially from the depostate itself. Probing this medieval Byzantine-Greek chapter has been hampered by an absence of historical narratives and biographies of the despots. The chronicles that do survive are those of Byzantine historians from Constantinople such as George Pachymeres (13–14th centuries) [Donald M Nichol, in Zarkadas].
