Sorry if this has been answered before, but I searched and couldn't find it.
How do the rules of succession work?
I decided to prune my family tree a bit, as there seemed to be something... wrong... with the ruling branch. (My former heir apparent died of old age before his father and without any children. After the king died, his second son (childless) became king, and thrid son (unmarried and "dangerously mad") became heir.)
So after my insane heir died while insanely invading Turkey singlhandedly
, the position of heir passed to one of the king's cousins (specifically, the son of the grandson of the original faction ruler). However, the heir's father is still alive.
Simplified family tree below:
So not only has the succession skipped Iosef and gone to his son, but (if I'm reading the tree right), Iosef had an elder brother (Ivan), so I would have thought the succession would have passed to that branch of the family.
So how/why did the succession pass this way?
