In my game as the king of Ireland/Wales/Castille, my dear neighbour the king of Scotland, for some crazy reason, agreed to have his brother, who is eligible to the throne, marry my sister in a matrilineal marriage.
The kingdom of Scotland has an elective succession law, and it consists of five duchies. The king himself owns a single duchy, but there's another guy owning three! The last remaining duke is married to some girl of my dynasty. On top of that, one of the earls is in my dynasty. I don't know if the last two things really matter in the equation, but they seem to like me well enough.
Now, I do know I won't get to control Scotland personally, but it's better to have my friend do it, than some Scottish chump.
So how do I rig this election?
I'm thinking of showering my new favourite brother-in-law with fancy titles, to make him a more attractive choice.
Or could I try to bribe the superduke? Would that even influence his choice?
Is it even possible to rig an election in a different realm?
