I am currently playing as the Roman Empire (I started out as the Byzantines and reunited the Roman Empire) and I've conquered huge areas in the world.
For example, I control all of the De Jure empire of Arabia, and the kingdom of Mesopotamia of the Persian Empire.
I am currently assimilating the de jure kingdom of Italy into my de jure Empire etc, however, I am not doing the same with regions that are part of another de Jure empire, even though neither the Persian Empire nor the Arabian Empire exist.
A friend of mine said that I need to control all de jure Duchies and Kingdoms within the empire, however, in the case of Arabia I already do that (well, my vassals) but it still doesn't get assimilated.
The fact that I will soon have assimilated the kingdom of Mali into the Roman Empire but not for example Egypt or Mauretania is kind of weird, if you see where I'm geting with that.
Why is that? And how, if possible, can I start assimilating territory of a non-existent de Jure empire into my empire?
