Michael Psellos
In November 1058, Keroularios was arrested and exiled, and died before a synod to depose him could be convened. The eastern frontier held firm during his reign, Hungarian raids were resolved by a treaty in 1059, while the restive Pechenegs were subdued by Isaac in person in summer 1059. Shortly after, Isaac fell ill, and on the advice and pressure of Michael Psellos, he abdicated his throne in favour of Constantine X Doukas, retiring to the Stoudion monastery where he died later in 1060.
