If you're just a measly king, well, it's more complicated, and you probably have to get your heir educated by some freak from Bassackwardsville and deal with the attendant wrong religion/culture malus. For some reason, Frisia is the Kingdom that I enjoy most having formed and part of my empire. Additional religions and denominations are available in converted savegames from Crusader Kings II.Many of these are heresies in CK2 if a heresy becomes more widespread than the parent religion, the parent will become a heresy and vice-versa, and the former heresy will replace it in a game exported to EU4. I do try to get members of my dynasty to adapt the necessary cultures, mostly because I like having a multi-ethnic family, but sometimes I just want to form Frisia now.

This is a dirty, but very effective tactic. You're king of Wales/Brittany/Frisia/Finland/Pomerania/Whateverthehell. Once he forms the kingdom, just revoke all his titles because he's a filthy pagan.

Grant at least two duchies and transfer all de jure vassals to him. If you're rather large and already an emperor, and you've already taken enough territory to form the kingdom in question, you can invite a courtier with the appropriate culture/religion and at least 200 piety.
