We should be able to become rulers of existing factions

[King Harlaus The Fat]

We should be able to usurp the throne of any faction via a civil war.

Every single faction in Bannerlord is an elective kingdom for some reason (even if that goes against their entire social structure), so you are able to become king once the current one dies.

You can kill with friendly fire too, so with enough tries you can assassinator your king and trigger the election!

TW should call you when they become serious about fixing exploits.

You can kill the current king by using the campaign.kill_hero console command. You should wait to do this until you are the most powerful lord. That's how I became the king of Vlandia. I was elected by unanimous consent too.

Poor King Derthert, he accidentally fell on his sword. Twenty seven times. Backwards.
