There was a western one. It just fell apart, was partially reconquered by the eastern empire, then fell apart again, then, well you get the picture.
Why eastern? There was no western one. :rofl:
I really can't believe people are prepared to argue over the name again. The reasons it will be named "The Byzantine Empire" are the following:
1. This name is more well known than the "Eastern Roman Empire".
2. It sounds way cooler.
Lets end the discussion about how the Byzantine Empire should be named here, since that is not the purpose of this thread and it also is an issue that has been discussed over and over again.
I do wonder if they will have put the Romans in the game already from vanilla though, I sure hope so but the differences with the rest of medieval Europe might make it hard to portray it well enough to warrant having it playable. It worked in Crusader Kings 1 but it wasn't very accurate.
How you plan to portray the autonomy level that the byzantines had with different nations during this period. fe it is known that their relationship with arbanon was based on isopolitia concept more or less the same as romans had with foederatus tribe?
