Can someone explain to me how the de jure kingdoms change and what criteria is required for this to happen?
When I look on the de jure kingdoms map I've noticed that certain territories in Anatolia are on there way to becoming the Sultanate of Rum and a couple in Southern Italy are becoming the Sultanate of Africa. But others aren't. Why?
Is it possible to expand the de jure 'kingdom of Byzantium' playing as the Byzantine Empire?
