These women will occasionally convert their husbands or courtiers and the religion will spread. To spread your reformed religion peacefully, marry Reformed Germanic women to pagan men in the east. This is probably better, since the supply limit (especially in winter) and pagan defensive bonuses of Suomensko/Romuva/Slavics make them extremely hard to attack, especially with tribals. Spreading your religion East, into Pagan lands, can be done peacefully.

You won't necessarily get the new ruler as a vassal (there are ways) but even if you don't, they'll be of your religion, potentially your ally, and have 100 opinion of you. Wars to press claims don't allow neighbours of the same religion to join in- only allies- so you should be fine if you're not attacking Francia or another massive realm. Invite claimants to your court, wed them to your daughter/sister if possible, and convert them.

It's almost impossible to spread one organised religion into another organised religion's lands.Īs well as holy wars, you can invite and press claims of characters. Spreading your faith west, into Christian territory, will require war. You can get your dynasty on a foreign throne, but it will not be easy and requires quite a bit of luck. If you capture one more aged, force them into a marriage with a Norse. Their future vassals will not be happy, but maybe you can try to help him once he is on the throne. if you grab them young, you should be able to convert them to the One True Faith™. Unless you are going North Korea style, you'll have to give them away anyway.Īnother method, much more difficult, is to try to capture an heir to a big chunk of land. The most efficient way is to give them to vassals, who will each have a court priest to proselyte inside the demesne. Still, catholics kingdoms tends to be quite divided. Other Catholic are more likely to join the defender than during a regular holy war. Great Holy Wars will allow you to take a whole kingdom at once, but they are much more difficult. You should be able to grab a few duchies at a time trough holly war, and may even get them without having a truce. If you attack at a time where your enemy is divided (succession crisis, during another war etc.) they may not be able to call allies, while you have the full force of an empire with you. I'd say that holy-warring is still the most effective way, especially if you have the full force of an empire behind you.
