Andronikos Angelos Doukas (, – before 1185) was a Byzantine aristocrat related to the ruling Komnenos dynasty. During the reign of his cousin, Manuel I Komnenos, he served without success as a military commander against the Seljuk Turks, and as envoy to the Kingdom of Jerusalem. Following Manuel's death, in 1182 he was sent to stop the rebellion of Andronikos I Komnenos, but was defeated and eventually defected to him. Shortly after, he led a failed conspiracy of leading aristocrats against AndronikosI. When it was discovered, Andronikos and his sons fled the Empire, ending up in Acre, where he died. He was the father of emperors Isaac II Angelos and Alexios III Angelos. Life Andronikos was born around 1133, the third son of Constantine Angelos and Theodora Komnene, the youngest daughter of Emperor Alexios I Komnenos and Irene Doukaina. Some time before 1155, probably around 1150, he married Euphrosyne Kastamonitissa, sister of Theodore Kastamonites, who became an all-powerful minister during the reign of Andronikos' son IsaacII. Andronikos is first recorded in historical sources during a synod in March 1166 that was convened over the interpretation of Christ's statement "My Father is greater than I". He participated in it along with his brothers and other senior members of the court and ecclesiastical hierarchy. In 1176 Andronikos, and his older brother John, commanded units in the imperial army's vanguard in the campaign against the Seljuk Sultanate of Iconium. The campaign culminated in a heavy Byzantine defeat in the Battle of Myriokephalon. In the following year, Andronikos led an embassy, which included the megas hetaireiarches John Doukas, Alexander, Count of Gravina, and George Sinaites, to the Kingdom of Jerusalem to renew the alliance between his first cousin, Emperor Manuel I Komnenos, and King Baldwin IV.
