Recruit independent Clans that are in War with my Kingdom?!

[Vontanius]

Hello, I have destroyed Vlandia with my own kingdom and the independent clans are now at war with me and I can no longer annex them. No matter if I make peace or not. The option is not available, I can only hope that they will join someone else.

But I don't feel like going back many savegames now and am wondering how I can solve the problem most elegantly and quickly. I have 2 of the 3 clan members with me as prisoners, the other is in jail in one of my vassal's castles.

What would be the quickest, shortest and easiest way to solve this problem? Cheats, but then the effects of annexation are removed, or a mod that allows me to do this very quickly directly after installation, without having to move around the map?

I'm kind of looking for a quick method without changing too much. (I would have had to annex the 3 clans before besieging the last castle of Vlandia.)

Sorry for the long message, I thought I was in the right place for this. :)

There's no way to recruit factionless clans in the vanilla game. There are various mods that have that feature in some form. There aren't any console commands I am aware of to force a clan into a faction.

I *think* the Diplomacy mod offers this feature provided you are the ruler of your faction. You generally have to talk to clan leaders to get them to join you. You could use a console command to make an NPC your prisoner and talk to them there, provided you are at war with them.

I use Diplomacy myself, and the mod claims that it can be added and removed mid game with no issues, so give it a shot. Make a backup of your save if you're unsure and you want to revert. The mod does quite a bit more that you may or may not want in your game.
