Justinians reign ends at 565, it's pretty interesting following him because he was a radical christian, and still wanted to maintain the whole Roman tradition - pretty creative solutions he came up with. If you feel like reading further into the Romans I suggest you spend some time doing this, Procopius is virtually the only historian we have on this period and he goes from praising the emperor in Buildings to comparing him with demons in Secret History, pretty entertaining if it wasn't for the time of the class.
