Countries That Have Controlled Jerusalem

Same. A pinned comment is probably more likely to be ignored on Jetpunk than a regular comment sometimes, surprised nobody's done anything to get their account banned so far

I personally think the term "Caliphate" should work for that one, even if not the others. Even though all the subsequent Arab-ruled Islamic Empires assumed hegemony and claimed the Caliphate, only the first one was the undisputed political and spiritual hegemon and, technically, the only true caliphate, in the sense that it was a successor state to Muhammad's nation (i.e. following his example in leadership). All the following were essentially imperial dynasties. Maybe this isn't a well-known fact among historians but it should be. It could also be just a massive nitpick on my part.

Yes, the Khwarazmian Empire are missing; they seem to have held it after an invasion in 1244. But maybe they are under the other empire, I'm not familiar on the subject.
