Alexios Komnenos governor of Dyrrhachium

Alexios Komnenos was a Byzantine aristocrat and nephew of Emperor Alexios I Komnenos. He was born around 1077 as the second son of Isaac Komnenos and Irene of Alania. As an imperial relative, he held the title of sebastos and served as doux of Dyrrhachium from 1106 until after 1108. Appointed by his uncle to replace his older brother John, who had proven unreliable, Alexios played a crucial role in defending Dyrrhachium during a siege led by Bohemond I of Antioch in 1107–1108. Using Greek fire, the defenders successfully repelled the Normans, leading to the Treaty of Devol, which recognized Emperor Alexios's suzerainty over Bohemond.

Alexios’s early life and career remain largely unknown except for his marriage to Zoe, whose family is unspecified. After his defense of Dyrrhachium, details about his subsequent life are absent. However, it is known that he likely had a son named John, mentioned in a funerary poem. The text also briefly mentions an incident involving Alexios's wife, Zoe, who fell ill around 1130 and was subjected to sorcery accusations by foreign charlatans. These events led to interrogations and torture of servants but ultimately resulted in the charlatans fleeing. Some individuals involved were later punished for their actions by Patriarch Leo Styppes.
