One of my vassals has now created the Kingdom of Asturias. If I'm reading correctly, if I revoke the Kingdom of Asturias, I should be able to create the Kingdom of Leon?Yeah, this is what I'm referring to. They have all the required land, they just need have the title k_asturias to make the decision to create Leon.
Another question:
How can I request a crusade?
I've vassalized the Pope and have 'external wars only' law.
I've seen this option before when clicking on the pope, but now it never appears.
