And Constantine is known for many things. Maybe most famously, he embraced Christianity as opposed to Diocletian, who persecuted Christians. You have the Council of Nicaea and the Nicaean Code, where there's now a uniform church doctrine around Christianity. He has the Edict of Milan, which makes Christianity illegal under Roman rule. Maybe most famously, on his deathbed, he gets baptized. He becomes the first Christian emperor. He also moves the capital to, officially moves the capital of the entire empire to what at the time was Byzantium, but then he renames it to Constantinople, named after him.
