So I'm playing as Ireland, having united the British Isles, conquered half of Iberia, A nice bit of France, all of Norway and Sweden and converted to Judaism. I conquered most of egypt all of Jerusalem, and damascus so that i could build the Third Temple and get a religious head to call great holy wars with. The first great holy war he called for Mesopotamia and now it's been over 30 years since but I can't request a great holy war? The button isn't just greyed out it's not there at all. I want to take Aquitaine because it's my largest rival & taking it out would make future crusades called against me a lot easier, plus i plan on converting into EUIV so it would help me monopolize colonization but when I go to the diplomacy screen for the king of Aquitaine there's no option for requesting a great holy war?
