And remember, they have this missionary zeal, and it really becomes a significant purge under the reign of Diocletian. In previous videos, we talk about Diocletian. He's the one that famously split the empire between East and West, but he's also famous for his Purge of the Christians, the most extreme state-sponsored purges of Christians in the Roman Empire. But what's interesting is right after or shortly after those purges, we're talking a few decades here, the next emperor who would have reign over the entire Roman Empire would be Constantine. And at least relative to Christians, he would be the opposite of Diocletian because as he's trying to consolidate his power, in 312 CE, you have the famous Battle at the Milvian Bridge outside of or entering into Rome. And in this battle, Constantine, he sees a vision of the Christian cross centered on the sun, and he thinks that that is a sign that he should fight under the cross. And he gets the symbols painted on his soldier's shield, and he's victorious.
