Kuchuck I Sultan ?

I really can't say if the AI is permitted to back the rebels in a civil war, but from your description above it does appear so. This seems to me to be the only way that a so named Sultan could succeed to the throne. The AI must have bribed them, then they must have been part of the low loyalty side in a civil war and ultimately, assuming the AI did back the rebels, this general became Sultan.

That's pretty unusual, Omar. Can't say I've seen anything like it myself, but that certainly doesn't mean anything. I have to admit that until you brought up the subject, I'd never considered whether the AI even gets a choice in which side to back in a civil war--I'd always automatically assumed it supported the Loyalists. Guess I'll have to rethink that assumption.
