So, question: what is the best way to turn an elective empire into a primogeniture one? I got back byzantium, held off a jihad, and took land from the Fatimids. Now my character is old and about to die. What is the best way to make sure that the next Basileous is one of my successor's sons? I would like to actually use the bonuses that "born to the purple" gives.
I just have the base game, so any funny business that involves way of life or legacy of rome will have to wait until I save up and get those.
