Although Theodora and Zoë appeared together at meetings of the Senate or when they gave public audiences, it was soon apparent that their joint reign was under considerable strain. Still jealous of Theodora, Zoë had no desire to administer the empire, but she would not allow Theodora to conduct public business alone. Court factions formed behind each empress. After two months of increasing acrimony between them, Zoë decided to search for a new husband, thereby denying Theodora the opportunity to increase her influence through her obvious talents for governing. She eventually married Constantine IX, on 11 June 1042, and the management of the empire reverted to him. Although Theodora and Zoë continued to be recognised as empresses, and although Theodora continued to appear at all official functions, power devolved onto her brother-in-law. Nevertheless, Theodora exerted influence at court, as demonstrated by her ordering the arrest and blinding of John the Eunuch, the powerful administrator who had been the chief minister of Romanos III, the brother of Michael IV, and the uncle of Michael V; he had lived in exile after the fall of Michael V.
