With Michael IV's death in December 1041, Zoë adopted Michael's nephew, who was crowned as Michael V. Although he promised to respect Zoë, he promptly banished her to a monastery on the Princes' Islands on charges of attempted regicide. This treatment of the legitimate heir to the Macedonian dynasty caused a popular uprising in Constantinople, and on 19 April 1042, the people dethroned Michael V in support of not only Zoë, but Theodora as well. Michael V, desperate to keep his throne, initially brought Zoë back from Princes' Island and displayed her to the people, but the population rejected his proposal that he continue to rule alongside Zoë.
