How do i do a war for an entire dutchy or kingdom instead of just taking on county at a time

[MyTurdsEatPPL]

With this i mean like is there a way to fabricate claims on entire dutchies/kingdoms or no

[Bordric]

Need someone with claim to entire kingdom or duchy. Or yourself have a claim. I am not sure if there is a fabricate claim for duchy level. If there is I have not used it.

Or holy war.

Large claims mostly come through marriage and breeding.

When a parent dies, their children get Pressed Claims on their titles. When that child dies, their children inherit the claim as a downgraded Unpressed Claim. When someone with an Unpressed Claim dies, the claim disappears.

Thus, getting a claim on a title normally works like this:
1. Find a title you want to get a claim on.
2. Marry the title owner's daughter to your first son.
3. You die and become your son. You son's father-in-law dies, and your son's wife gets a Pressed Claim on his title.
4. Your new character and their wife have a son.
5. You two die. You start playing as your son, and he inherits his mothers Claim as an Unpressed Claim.
6. You now have a claim on the title you wanted, ready to be pushed in a war.

Breeding claims into your dynasty tends to be a pretty slow process, which happens over a couple of generations.

There are, of course, other ways to get high-level titles. You can declare Kingdom-level Holy Wars against Hostile faiths, some perks/faiths let you "fabricate" claims on Kindom level titles under certain circumstances, you can press other people's claims, etc. However, your bread-and-butter will be always be breeding claims into your offspring via marriage.

For duchies, my personal favourite is to go down the scholar tree in the learning lifestyle and get the Sanctioned Loopholes perk to buy duchy and county claims in exchange for piety.

But not all rulers can get down the learning tree that quickly, so setting a good realm priest to craft claims on counties can sometimes lead to them fabricating a claim on the whole duchy. It's a bit more RNG, but you can always do it if you don't go down the learning tree.

Some religions can do duchy level conquests because of their tenets. You can also make a new religion and take a tenet that gives you Conquests. Like Pursuit of Power for a Christian religion. Finally, if you have Royal Court you can use the Quarrelsome tradition to get access to duchy and county level CBs.

Couple ways to get full duchy claim:

-Have your realm priest fabricate claims and there is small chance of getting duchy claim.
-Holy wars have duchy/kingdom claim depending your piety/level of devotion.
-Having title claimants in your court and pushing their claims.
-Having claims through marriages.
-Having your realm priest fabricate claim on all counties in duchy (when not getting lucky duchy claim) and push those claims and take whole duchy. Requires Divine Right innovation from High Medieval to able to push your multiple claims in single war.
-Having Ducal conquest perk from Diplomat skill tree this allows to claim whole duchy IF duchy title is not created yet and you have claim to one county in said duchy area.
-Tribal system has Conquest CB which can target duchies depending your level of Fame/Prestige.
-Chronicle Writing Innovation in Early Medieval allows you to take remaining duchies in case where you have conquered enough land to form kingdom/empire title/ or yoink it from somebody else but are missing one or to duchies from that Kingdom/empire de jure.

If you're Catholic and you have virtuous stats, high piety, and a good relationship with the pope, you can also request and receive claims on duchies or even entire kingdoms. It's pretty OP to be a pious dude with high diplo and a lot of alliances in the HRE.

The forged duchy claim is a random "proc" - occasionally your priest will ask you wether you want that instead of the intended county claim.

I wouldn't recommend accepting that for several reasons:



If your rank is King or higher, you do neither get the claimed duchy title nor any counties. UNLESS the target duchy was owned by the target realm's top liege personally.
(The county claim always gives you the county for yourself)

So instead of getting fresh land and a new title for your sons to inherit, you get a new Duke vassal who most likely hates you, has terrible contract settings, possible claims on your other vassal's titles, and allies abroad. Often this vassal also owns counties he shouldn't have, creating more border gore and stress in the near future.


Generally smarter to just keep forging county claims against different neighbors, then usurp the duchy titles and start a de jure duchy war afterwards.
