Justinian would famously try to reform Roman law, make it more consistent, make it more clear. Justinian's Code. And you have the Emperor Leo III has the famous Ecloga. But as you have these revisions and these reformations of Roman law, they are more and more written in Greek than Latin, and they do have more and more of a Christian influence. In terms of governance, especially under the Roman Empire, the notion of a province was the main subdivision under which the empire was governed. Once you have Emperor Diocletian come onto the scene, and this is shortly before the time of Constantine, he reformed it, and he set up what is known as a tetrarchy, where you had these two emperors of east and west, and then you would have, essentially, their subordinate emperors. But along with that, he redefined what a province is, so you had smaller provinces, which then would go into diocese, which would then go into prefects, which would then go into a tetrarch.
