Culture Switch - Vassals

A Bannerlord mod that lets you ask vassals to adopt your culture.
(Tested up to v1.2.9)

Particularly useful with the Dynaculture mod.
Of course you need to be king.
Works anywhere as long as you can talk to a lord, with a relation >50.

Note that when you give a settlement to a companion, the game doesn't show that the new clan has the culture of the settlement given, regardless of your companion's culture. This mod switches the clan culture too.

Also note that you can ask a clan leader to convince his members to adopt your culture, even if the leader himself already has your culture. (for spouses and children)

Should work with modded cultures too, although I didn't try any.

No mod requirement.

Can be added/removed in the middle of a campaign, but culture changes will remain so I'd suggest grabbing a save before convincing a lord to switch.

You can have a look at a similar mod but for companions and clan members.
