Answer
In 1042, Zoe's triumphant return to power was ignited by a groundswell of popular discontent. The empire's subjects, exasperated by the oppressive rule of Michael IV and his ruthless brother John the Orphanotrophos, rose in revolt, demanding the restoration of Zoe, who had previously demonstrated fairness and compassion during her brief reign. This uprising, fueled by widespread dissatisfaction, ultimately led to Zoe's triumphant reinstatement as the Byzantine empress.
