Now what we're going to do in this video is continue the narrative, and in particular, we're going to see how there's an evolution between the church in the west and the church in the east. In previous videos, we already talk about how the Roman Empire itself is initially administered between west and east, and then that administration becomes more and more formal. Theodosius is the last emperor to truly rule both halves. They start getting ruled separately, and as you get into the latter half of the fifth century, the Western Empire itself falls to Germanic conquerors. Now in previous videos, we talk about how the emperors who rule from Constantinople consider themselves to continue the Roman Empire. They didn't call themselves the Byzantine Empire, as we now call them. They called themselves the Roman Empire.
