[DUCA311] Andronicos Ducas [born c.1035] married (before 1063) [BULG312] Maria (born c.1045, daughter of Trajan, see BULGARIA). Andronicos commanded the rearguard of the Byzantine army in EMPEROR ROMANOS IV's campaign against the Seljuk Turks at the Battle of Manikert (1071) when he announced (wrongly) that the Emperor had been cut down, and Andronicos deserted the battlefield. This probably led to the subsequent crushing defeat of the Byzantine army by the Turks, and their capture of the Emperor, who was effectively deposed. The ex-Emperor was released (1072) and the new Emperor (Michael VII) ordered Andronicos, his brother Constantine and their father Caesar John Ducas to intercept Romanos, which they did and captured him in Cilicia. They returned with him to Constantinople where Romanos was blinded (29th June 1072) on the orders of Caesar John Ducas, apparently opposed by his son Andronicos. Andronicos and his father John fought against Norman rebel mercenaries (1074) but were both captured. Andronicos was released and allowed to return to Constantinople for treatment, though his father continued to be held for ransom for a while longer. Andronicuo then became a monk, taking the name Antonios, whilst Maria became a nun taking the name Xene. Antonios died 14th October 1077.
