Dioceitian came to power another problem that he wanted to fix was the way Roman empporers were chosen

. Previously, the emperor was usually chosen based on their military strength or political influence, often leading to contentious power struggles and civil wars. Dioceitian implemented a new system known as the Tetrarchy, which divided the empire into four regions, each ruled by a senior emperor (Augustus) and a junior emperor (Caesar). This system aimed to promote stability and ensure a smooth transition of power by having designated successors in place.

Additionally, Dioceitian introduced stricter regulations on the eligibility of candidates for the imperial office, requiring them to have a certain level of military or administrative experience. This helped to professionalize the role of emperor and reduce the likelihood of incompetent or weak rulers coming to power.

Overall, Dioceitian's reforms to the process of choosing Roman emperors were aimed at promoting stability, efficiency, and competence in leadership, ultimately helping to strengthen the empire during a time of significant challenges and threats.
