John Komnenos was a Byzantine aristocrat, the nephew of Emperor Alexios I Komnenos and long-time governor of the strategically important city and theme of Dyrrhachium from 1091 to.
Biography
Early life
John was born in late 1073, the eldest son of the sebastokratorIsaac Komnenos, older brother of Emperor Alexios I Komnenos, and his Georgianwife, Irene "of Alania". In 1081, his uncle, Emperor Alexios, proposed a marriage match between John and a German princess to the Holy Roman Emperor Henry IV. Alexios recommended his nephew as both handsome and of prudent character, but nothing came of this proposal.
Career
In early 1091, John was chosen by Alexios to replace John Doukas as the governor of Dyrrhachium, in modern-day Albania. The city was of great importance to the Byzantine Empire, as the "key of Albania" and the main point of entry from Italy into the Balkans, a fact illustrated by the role it played in the Norman invasion in the early years of Alexios's reign. Soon after the assumption of his duties, however, he was accused by Theophylact of Bulgaria of plotting against the Emperor. To defend himself against the accusation, John travelled to Philippopolis, where Alexios resided. It is not clear whether the allegations had any substance; nevertheless, the affair evolved into a family quarrel between Alexios and his brother Isaac, who was also present. Eventually, Alexios dismissed the allegations and reconfirmed John in his post. Later, in 1094, despite his military inexperience, John was charged with confronting raids by the Serbs under Vukan of Rascia into the Byzantine province. John allowed himself to become involved in prolonged negotiations with the Serbian ruler, giving him valuable time to prepare his forces. When he was ready, Vukan attacked the Byzantines near Lipenion and inflicted a heavy defeat upon them. John travelled to Constantinople to explain his defeat to Alexios, but was not relieved of his post. In 1096, he received and hosted Count Hugh I of Vermandois, whose fleet had shipwrecked off the coast of Dyrrhachium. John was probably still doux of Dyrrhachium in 1105/06, when he is recorded by Anna Komnene to have been defeated in a campaign against the Dalmatians. As the threat of a renewed Norman invasion by Bohemond loomed, the emperor replaced John with his younger brother Alexios.
Marriage and family
In, John married Maria Doukaina, daughter of the protostratorMichael Doukas, a brother of Alexios I's empress Irene Doukaina. His wife's name is only attested while she was a nun, so it may represent a monastic name, rather than her birth name. The couple had five children, all of which died early, before their parents. Only the name of a son, Alexios, is known. Some time after 1130, John and his wife became monks, with John assuming the name of Ignatios. He tore down his father's palace and in its stead erected a monastery dedicated to the Holy Trinity, under the name of Euergetes. Their last child probably died, which therefore is also a terminus post quem for the deaths of John and his wife.
