In the fourth century, Valentinian was the only Roman emperor who had a choice between ruling the East or the West and chose the West.

Christians constituted at most 10% of the Roman Empire's population under Constantine, with a Christian majority emerging around the 5th century and reaching roughly 85-90% by the early 6th century.

"We probably can't talk about a majority Christian society until maybe the 5th century or early 5th, mid-5th... And we can't talk about like a solidly Christian society until early 6th century. And by solidly, I mean maybe where the non-Christians are 10, 15%... So, very slow conversion, maybe up to 10% tops under Constantine" (said at 1:37:51)
