What are the comparison between Diocletian and Constantine?

Diocletian and Constantine were both Roman emperors who implemented significant reforms but differed in their approaches and legacies. Diocletian is known for establishing the Tetrarchy, dividing the empire into four regions to improve governance and stabilize a crumbling state, while he also enforced strict economic controls and persecution of Christians. In contrast, Constantine is celebrated for embracing Christianity, issuing the Edict of Milan which granted religious tolerance, and founding Constantinople as a new capital, thus shifting the empire's focus eastward. While Diocletian sought to restore traditional Roman values, Constantine's reign marked a pivotal transformation towards a Christian empire.
