I thought Jihads could only be declared against territories that an islamic power had previously held? Well, I had the bastard moors declare a jihad against Saxony, a province that I am quite certain they have never held in this game. Bug?

On Crusades, I find them very annoying. The English declared one to Valencia...and then spent 15 years loitering about my lands trying to suck up my troops. What determines how many of your armies will join a crusade? I know zeal has something to do with it, but what else?

Thanks
