معركة ملاذكرد
When Romanos was taken prisoner by the Seljuk Turks at the Battle of Manzikert (1071), Eudokia and Michael again assumed the government, until it was discovered that Romanos had survived and was returning to Constantinople. John Doukas and the Varangian Guard then compelled Eudokia to leave power to Michael and retire to a convent.
