On January 1, 1068, Eudokia married the general Romanos Diogenes, who now became senior co-emperor alongside Michael VII, Konstantios, and another brother, Andronikos. When Romanos IV was defeated and captured by Alp Arslan of the Seljuk Turks at the Battle of Manzikert in August 1071, Michael VII remained in the background, while the initiative was taken by his uncle John Doukas and his tutor Michael Psellos. They conspired to keep Romanos from regaining power after his release from captivity, while Michael felt no obligation to honor the agreement that Romanos struck with the Sultan. After the dispatch of Eudokia to a monastery, Michael VII was crowned again on October 24, 1071 as senior emperor.
