They'll only be your vassal if they are already your vassal, they're in your dynasty, or the claim you pushed was for an area that is de jure part of your realm. When pushing someone else's claim however you have to be careful, or they'll end up as an independent realm. Pushing your own claims and similar is rather straight forward. That said, adopt this position with caution while this approach means gaining a casus belli on everyone, it also means everyone gets a casus belli on you! Which means that unless you are the largest fish in the pond, things are likely to get very ugly fast, and even the almighty Holy Roman Empire is vulnerable to dogpiles. So while the drawbacks of heresy are severe (-30 opinion with all non-heretics, and increased rebel risk), the advantages when it comes to expansion are huge. You'll now have CBs upon everyone except other realms following the same heresy. Then upon the first chance you get, you should change to whatever heresy arises. The lower the moral authority of the church, the more likely heresy is to spread. The easiest way to get heresy to appear so that you can convert is appointing an antipope, as this lowers the moral authority of the church. You can get religious war CBs on essentially the entire world if you convert to a Christian heresy. If you are Catholic, you can attack Pagans, like the Balts and Finns.

They're good for gaining some prestige, though.įifth, you can attack someone of a different religion to claim a Duchy. Third, dispute succession CBs can, like general claims, be gained by inviting someone with that CB to your realm.įourth, excommunication CBs are easy to get as long as the pope likes you, but these won't help you grow your realm. In addition, after pushing a claim for a duchy, you'll often have de jure claims. If you can create a duchy that overlaps another realm's territory, this will gain you a de jure claim, and the same applies if you usurp it. Second, de jure ducal claims are also relatively easy to gain. Invite someone with a claim to your realm.Their children will have the claim, and you'll be able to push it Marry someone in your dynasty to someone who has an inheritable claim.Your children will have the claim and you can then push it

Marry someone who has an inheritable claim.This doesn't work for anything above the ducal level (skill of 15 needed to forge a ducal claim) (or for anthing below the county level, like a barony) Forge the claim using your Chancellor.There are four primary ways to gain claims: While some of these CBs you'll have merely due to your position, like the independence CB and the law change CBs, many of these can be gained on purpose.įirst, the easiest type of CB to gain are claims.
