I don't believe there's a limit either. In my Turkish campaign, I converted most of the Pope's subjects to Islam, using a couple of Alims in each province. Then there was a Muslim revolt in the Papal States They defeated the Pope and forced him into exile; curiously, the message still stated that they had set up a puppet Pope. It seems odd to me that Muslim rebels would set up a Pope. What's even stranger is that when the Pope reappeared a few years later, the former Muslim rebels joined with him This game is decidedly wierd...

Maybe if I ever pick up that game again, I'll send Jihads to Rome and the Papal states. See, I'd sent one of my low-loyalty generals (a bribed rebel) with his army on what was pretty much a suicide mission to attack the Pope. However, he actually won, defeating the Pope's army and eliminating the Papacy He marched across Italy, looting and burning; Rome was razed to the ground. He then managed to hold out in the Papal States with his survivors until he could build a port and escape. What a crazy adventure. Rome is still mostly Muslim; I still chuckle at the thought of a Jihad going to liberate them from Catholic rule.
