And ever since the fall of Rome, there has been a lot of tension in Western Europe between popes and kings over who should have the real power. But in the Orthodox Church, they didn't have that problem because the patriarch was always appointed by the emperor. So it was pretty clear who had control over the church, so much that they even had a word for it, Caesaropapism, Caesar over Pope. But the fact that in Rome there was no emperor after 476 meant there was no one to challenge the pope, which would profoundly shape European history over the next, like, 1200 years. So I would argue that in some important ways, the Roman Empire survived for a thousand years after it left Rome, but in some ways, it still survives today. It survives in our imagination when we think of this as East and this as West. It survives in football rivalries that have their roots in religious conflicts, and it survives in the Justinian law code, which continues to be the basis for much of civil law in Europe.
