Crusader Kings 2 - How to conquer the Seljuks (or any other realm) without any war

Trivia: Doing this to realms with the same religion as you is easier, because you dont need favors to invite the direct heir of the King.

It only works on lower tier vassals. For example playing as emperor versus a king. It wouldn't work against abbasids for example

[@farry882]

you could screw up the abbasids by doing this to their vassals as long they dont have regulated inheritance ;)

@@farry882 it's a good way, especially when the whole world is in a defensive pact with u. I on the other hand took everyone as a vassal through the same society. Independent rulers of your society tend to become your vassals, just like same culture.
