Leo Sgouros (Greek:Λέων Σγουρός),Latinized asLeo Sgurus, was aGreek independent lord in the northeasternPeloponnese in the early 13th century. The scion of the magnateSgouros family, he succeeded his father as hereditary lord in the region of Nauplia. Taking advantage of the disruption caused by theFourth Crusade, he made himself independent, one of several local rulers that appeared throughout theByzantine Empire during the final years of theAngeloi dynasty.[1] He expanded his domain intoCorinthia andCentral Greece, eventually marrying the daughter of formerByzantine emperorAlexios III Angelos (r. 1195–1203). His conquests, however, were short-lived, as the Crusaders forced him back into the Peloponnese. Blockaded in his stronghold on theAcrocorinth, he committedsuicide in 1208.

Leo Sgouros succeeded his father, Theodore Sgouros, in circa 1198 as governor of the area ofNauplia and theArgolid, one of the districts known asoria, that collected taxes and provided ships for theByzantine navy.[2] In circa 1201/1202, when a rebellion inThessaly andMacedonia led byManuel Kamytzes andDobromir Chrysos cut southern Greece off fromConstantinople, several revolts broke out in thePeloponnese:Leo Chamaretos seized control ofSparta,Monemvasia was plagued by violent disputes among its leading families. Leo himself seized the opportunity to establish himself as an independent ruler, capturing the citadels ofArgos andCorinth.[3][4] His hostility to the church, who by that time were seen as the "defenders of the traditional order" in the words of Michael Angold, was profound: the bishop of Nauplion was imprisoned, while the bishop of Corinth was invited to dinner, blinded and thrown to his death from theAcrocorinth.[5][6][7] Indeed, Sgouros is generally presented as a violent man: in a letter,Michael Choniates, the bishop ofAthens, recounts how Sgouros beat to death a young relative of his who had been delivered as a hostage, merely because he had dropped a glass while waiting at his table.[8]
The imperial government despatched themegas doux,Michael Stryphnos, to counter him. Stryphnos spent the winter of 1201–1202 in Athens, but he was apparently unable to check Sgouros's power.[7] Soon after, while the Byzantine government was preoccupied with theFourth Crusade, Sgouros launched naval raids against Athens, enlisting the aid of the piratical inhabitants of the islands ofSalamis andAigina.[9] Choniates appealed to the Emperor's ministersTheodore Eirenikos andConstantine Tornikes, but in vain. In the end, he was forced to travel to Constantinople himself in another fruitless effort to secure aid. He returned to find Athens cut off from the provincial capital,Thebes, by Sgouros's troops.[6][7]
In 1203, as Constantinople wasthreatened by theFourth Crusade and despite Michael Choniates's entreaties, Sgouros moved against Athens, claiming that the city's inhabitants harboured a fugitive from justice. His men managed to take the city but the inhabitants, led by Choniates, continued to resist from theAcropolis despite a heavy bombardment with siege engines.[10] Sgouros left the Acropolis under blockade and after torching Athens marched intoBoeotia. Thebes was stormed, and Sgouros moved on intoThessaly.[6][11] NearLarissa, he encounteredAlexios III Angelos, who had fled the Crusader attack on Constantinople. In exchange for offering protection to the deposed ruler, he received the hand of Alexios's third daughter,Eudokia Angelina (her third marriage), and the title ofdespotes.[12][13] Sgouros was well on his way to forming an independent state of his own in southern Greece, which had every chance of becoming, in the words of the medievalist John Van Antwerp Fine, "a lasting affair", until the arrival of the Crusaders.[6]

In the autumn of 1204, following theircapture of Constantinople, the Crusaders underBoniface of Montferrat marched into Thessaly and headed south. Sgouros withdrew before the superior Crusader army. Initially he planned to make a stand in the pass of theThermopylae,[14] but he eventually retired to the Peloponnese, establishing a defence on theIsthmus of Corinth.[12] The army of Boniface took Boeotia andAttica without resistance, and relieved the blockade of Athens, where Choniates surrendered the city to him.[12] Boniface's first assault on Sgouros's defenses in the Isthmus was repulsed, but the second broke through, and by spring 1205 he controlled the countryside of the northeastern Peloponnese, while the fortified cities held out against him.[12]
Sgouros himself withdrew and was blockaded in his stronghold, the well-fortified citadel of theAcrocorinth, in a siege that was to last five years.[12][14] Sgouros's resistance was energetic, with sorties that harassed the besiegers. To tighten their siege, the Franks built two forts, one on the hill of Pendeskouphi and one on the eastern approaches.[14] According to legend, Sgouros eventually despaired, and in 1208 he jumped off the high cliffs on hishorse. Resistance was continued by a certain Theodore, but in the end, the citadel fell in 1210,[15] removing one of the last major centers of resistance against the establishment of theFrankishPrincipality of Achaea.
