context_page_description: Theodore Komnenos Doukas was ruler of Epirus and Thessaly from 1215 to 1230 and of Thessalonica and most of Macedonia and western Thrace from 1224 to 1230. He was also the power behind the rule of his sons John and Demetrios over Thessalonica in 1237–1246.
  Theodore was the scion of a distinguished Byzantine aristocratic family related to the imperial Komnenos, Doukas, and Angelos dynasties. Nevertheless, nothing is known about Theodore's life before the conquest of Constantinople and dissolution of the Byzantine Empire by the Fourth Crusade in 1204. Following the fall of Constantinople, he served Theodore I Laskaris, founder of the Empire of Nicaea, for a few years before being called to Epirus, where his bastard half-brother Michael I Komnenos Doukas had founded an independent principality. When Michael died in 1215, Theodore sidelined his brother's underage and illegitimate son Michael II and assumed the governance of the Epirote state. Theodore continued his brother's policy of territorial expansion. Allied with Serbia, he expanded into Macedonia, threatening the Latin Kingdom of Thessalonica.
context_section_description: Theodore was capable and extremely ambitious. Notwithstanding his oath to Laskaris, he aspired not only to expand his state at the expense of Thessalonica, but to eventually recover Constantinople and revive the Byzantine Empire with himself as its ruler. To secure his northern flank, Theodore allied himself with Serbia and the Albanian clans. The Principality of Arbanon had already come in the Epirote political orbit under Michael I, and closer ties developed when its ruler, Demetrios, died in 1215, leaving his principality to his widow, who promptly remarried the next year to a Greek magnate, Gregory Kamonas. Against the Serbs, Theodore abandoned Michael I's attempt to pursue a northward expansion into Zeta, and instead pursued an alliance with the Serbian prince Stefan II Nemanjić (r. 1196–1228) that was directed towards keeping the Bulgarians in check. The ties between Epirus and Serbia were solidified by the marriage of Theodore's brother Manuel Komnenos Doukas to one of Stefan II's sisters c. 1216. Stefan II then sought to wed one of his sons—in all likelihood his eldest son and heir, Stefan Radoslav—to Michael I's second daughter Theodora. The Archbishop of Ohrid, Demetrios Chomatianos, refused to sanction the marriage due to consanguinity—Theodora was a second cousin of Stefan Radoslav's mother, Eudokia Angelina, a daughter of Alexios III Angelos. In 1217, Stefan II tried to circumvent this by suggesting himself as the groom to Theodora's half-sister Maria, but Chomatianos vetoed this proposal as well on similar grounds. Finally, Stefan Radoslav married Theodore's firstborn daughter Anna in winter 1219/20.
  With his position thus strengthened, Theodore expanded his territory into northern Macedonia, although it is possible that at least part of this region had already been captured by Michael I after the death of the local Bulgarian ruler Strez in 1214. It is unclear to what extent Theodore's expansion involved direct conflict with the Bulgarian Tsar Boril (r. 1207–1218), but by 1217 he held Ohrid, Prilep, and most of the plain of Pelagonia, at least up to Strez's old capital at Prosek, and likely beyond, approaching the Strymon River. As the Greek historian Konstantinos Varzos has noted, the capture of Ohrid, seat of the eponymous archbishopric, was particularly important for the standing of the Epirote state and Theodore's aspirations. Theodore sponsored the election of the distinguished canonist Chomatianos to the archiepiscopal throne in 1217, and Chomatianos would repay that support with his steadfast championing of Epirote claims to the Byzantine imperial inheritance vis-à-vis the rival claims of Nicaea.
  Following the Fourth Crusade, the Orthodox clergy in the two main Greek states, Epirus and Nicaea, had effectively become separated. In 1208, the Nicaeans had convened a synod and elected Michael Autoreianos as successor to the vacant see of the Patriarch of Constantinople. The election was uncanonical and therefore of questionable legitimacy. This in turn meant that Laskaris' imperial title was also open to challenge, as he had been crowned by the same Michael Autoreianos. Already under Michael I, two local synods of bishops had emerged in the Epirote domains to carry on administration of the Church, largely independent of the Patriarch, one at Naupaktos under John Apokaukos, and one at Ohrid under Chomatianos. The more ambitious Chomatianos soon became the pre-eminent "western" bishop, and sought to strengthen the de facto Epirote autonomy in ecclesiastical affairs, including the appointment of bishops for the local sees without the Patriarch's interference. This policy, which dovetailed with Theodore's own ambitions of independence from and rivalry towards Nicaea, brought the two branches of the Greek Church to an open quarrel, as the Nicaea-based patriarch Manuel I Sarantenos began appointing bishops of his own to Epirote sees, whom the Epirotes refused to accept. Despite his close ties to Epirus, Stefan II Nemanjić exploited the Epirote–Nicaean rivalry to his advantage to secure autocephaly for the Serb
