Hello kings and queens, dukes and duchesses! I am back with another Dev Diary, and today we’re going to be talking about Factions and Civil Wars in Crusader Kings III!

Much like in CK2, vassals who are unhappy with the current state of affairs in the realm will create a Faction that other vassals can then join. Factions that grow large enough will eventually deliver an ultimatum to their liege, demanding certain concessions in exchange for continued peace.

Anatomy of a Faction
DD_WM_ExampleFaction.png
[A screenshot showing a Claimant Faction with Faction Members, Discontent, and Military Power displayed]

All Factions have a Military Power rating, which is a ratio between the combined military strength of all members and the military strength of their liege. Factions also have a Discontent score, which gauges how close the Faction is to sending their ultimatum.

Factions will begin accruing Discontent once their Military Power goes over a certain threshold, typically 80%. Stronger Factions acquire Discontent rapidly in an attempt to seize the moment, while weaker Factions hem and haw a little in the hopes that more supporters will join their cause. Either way, once Discontent reaches 100% the Faction will soon deliver their ultimatum; at that point, their liege must either accept their demands or fight all joined faction members in a civil war.

Civil Wars
DD_WM_CivilWarBorders.png

Unlike in CK2, when a civil war is declared faction members do not form a new temporary realm. While they nominally remain vassals of their liege, they will immediately stop providing taxes and levies to them, and their liege will lose access to certain powers (such as imprisonment).

During a civil war the faction members turn hostile to both their liege and all non-faction vassals, though they will focus on fighting their liege. The exact war goal varies depending on the Faction type, but both sides earn war score by defeating hostile armies and sieging down hostile provinces.

Once one side emerges triumphant, they will enforce their demands. A victorious Faction will enforce their ultimatum with some additional concessions thrown in, while a victorious liege will imprison all faction members and gain title revocation reasons against them. If a white peace is agreed to, things largely go back to the way they were, though the liege gains an imprisonment reason against all the rebels. Actually imprisoning the rebels is another matter entirely, as a failed imprisonment attempt can trigger another rebellion.

Types of Factions
There are currently 5 distinct types of Factions, each of which has its own goals.

  • The Independence Faction, seeking to gain independence from their liege.
  • Claimant Factions, seeking to replace their liege with a new one.
  • The Liberty Faction, seeking to reduce Crown Authority in the realm.
  • Populist Factions, seeking to form a new realm of their religion and culture.
  • The Peasant Faction, seeking to pay fewer taxes to their liege.

Vassals only join The Independence Faction if they feel like they do not belong in their liege’s realm. This can be due to a variety of reasons, but it generally boils down to a combination of three major factors: not being a de jure vassal of their liege, not sharing their liege’s culture [group], and their religious hostility towards their liege (more on that in a future Dev Diary!). As a result, Independence Factions tend to be ‘clumpy’, forming distinct regional blocs within a realm.

DD_WM_IndependenceWarTerms.png

Claimant Factions, on the other hand, are all about opinion. Vassals who personally dislike their liege while still feeling like they belong to their liege’s realm will favor this type of Faction. Of course, Claimant Factions are also an area where opportunistic vassals can push to acquire titles for themselves or their relatives!

The Liberty Faction is the place for vassals who are almost happy with the current state of affairs. They want to lower either the realm’s crown authority laws or their obligations to their liege, and are typically the easiest Faction to manage.

Populist and Peasant Factions are special in that they are not created by unhappy vassals. Instead, they are created by unhappy counties.

DD_WM_CountyFactions.png
[A screenshot of the Faction Tab showing an active Kurdish Apostolic Populist Faction and a Peasant Rabble Faction]

Much like vassals, counties have an opinion of their holder which is influenced by culture, religion, events, and war. When the opinion of a county drops too low, they will join one of these two factions. Like the other factions, if these factions gain enough Discontent, they will send an ultimatum, and will revolt if the ultimatum is refused. This completely replaces the random province revolt chance that existed in CK2 — gone are the days of “Duke McPeasantFace has declared the 19th Orthodox Uprising on you.”

Populist Factions are the more dangerous type of county faction and form when counties wish to be governed by a ruler of their own culture and/or religion. While Populist Factions are created by and primarily consist of counties, sympathetic vassals in your realm may also pledge loyalty to their cause. A successful Populist revolt will cause all member counties and vassals to break away and form a new realm!

While an Independence Faction causes all members split off into their own separate realms, a Populist Faction will create a single realm with all members united under one ruler. That ruler will always share the Faction’s culture and religion, and as a hero of the liberation war they will almost always be a competent commander. In addition, a successful Populist Faction will automatically usurp or create an appropriate title for their leader to hold, which can even generate new Kingdom-tier titles in certain circumstances!

DD_WM_SuccessfulPopularRevolt.png
[A screenshot of the Kingdom of Jüterbog, split off of the HRE by a successful Polabian Popular Revolt]

All of this taken together means that any realm formed by Popular Revolt will end up being a formidable foe that likely has several De Jure claims on its neighbors. This can substantially alter the balance of power in your region — even if you weren't the initial faction target!

On the other hand, Peasant Rabble are the simplest and least dangerous type of Faction. Unlike all other Factions, there is no minimum Military Power requirement for the Peasant Rabble to revolt, and its Discontent will always tick upwards at a constant rate. When the Rabble inevitably revolt, they will almost certainly be weaker than the liege they are targeting — but don’t let that lull you into a false sense of security! Every time the Rabble’s forces occupy a county, all of that county’s levies will immediately join them. What started as a minor uprising can quickly balloon out of control if left unchecked! Luckily their only demands are to pay reduced taxes and provide fewer levies to their liege, which is an annoying if manageable setback.

Faction Management

So as a ruler, how do you manage all of these Factions? Well, there are several ways!

For starters, any alliances you have made with your vassals will prevent them from joining a Faction against you. This makes arranged marriages within your realm valuable even if you don’t benefit as much militarily as you would from a foreign marriage.

Adding to this, any vassals you have a hook on will be unable to join a Faction against you, whether that hook is due to them owing you a favor or due to blackmail.

You can also attempt to intimidate vassals away from their Faction, as a high Dread will lower their willingness to be in one. If the threat of imprisonment and torture doesn’t work, actual imprisonment will — vassals in your dungeons can not be part of any Faction. Just be careful, as an unjust imprisonment attempt may provoke a powerful Faction into revolting early, regardless of their Discontent!

DD_WM_FactionRetaliation.png
[A screenshot warning the player that imprisoning this vassal may trigger a Faction Revolt]

Finally, if all else fails you can actually address the grievances your vassals have with you. Vassals who are happy enough will never join any kind of faction, which means improving their opinion of you and fixing structural issues in your realm will ensure that nobody challenges your rule!

That is all for this week, but I have an extra special treat in store you next time when we finally begin diving into how religion works in Crusader Kings III!

Blooper Reel: The Extremely Popular Revolt
Very early on in CK3's development, I started looking into ways to make Popular Revolts more challenging. No matter how large a revolt got, their forces would always be spread out across all of their member counties, making it trivial to pick off their armies one at a time.

To help remedy this, instead of letting each county spawn its own army I made it so each duchy would spawn a single army based on the combined military power of all faction counties inside of it. However, I made a mistake — instead of adding up the military power of all counties in a duchy, I accidentally added up the military power of all counties in the world... per duchy.

It turns out that no matter how many knights you have or how good of a commander you are, 8.8 million angry peasants will overwhelm you in battle every time.

Looks good! I liked that a country could fall apart and split in a civil war in CK2. I thought it was an amazing concept, and loved seeing it happen to AI kingdoms around me.


I hope that it takes some effort to maintain internal stability. I hope it actually does require one or two royal vassal weddings per king. In CK2, after Conclave and with all the stat and item bloat for +opinion, people just seemed to always like you enough to never revolt.

Please tell me that this system is leveraged to make maintaining a large empire more difficult than a smaller one. Like... if you have 3 daughters, you can marry two of them off to make 2 out of 5 powerful vassals peaceful, but if you have a large empire, you marry those two off but that's only 2 out of 10 powerful vassals.
Please tell me internal management takes effort (but is still fun). Please?

I hated how factions worked in CK2. Although this looks to be clear improvement, it still doesn't seem very fun. I wish there would be some way to make concessions without giving to their ultimate demand, ie. agree to make the claimant heir, reduce vassal taxes in exchange for not revolting for indepence...

This does make me wonder if the HRE will be reworked eventually, just as Eastern Roman Empire. Since they did have long periods of time when they had no emperor, nothing to go independent from. Nobody provided sufficient bribes to be crowned emperor.

And while it's just 1 nation, the HRE did play a very important part in Medieval Europe.

Much better than the CK2 system.

Please make faction ultimatums not completely dependent upon the whims of a single faction leader. Unless there is some reasonable mechanic to displace the faction leader's position. It is frustrating to be in a faction with overwhelming superiority only to watch the leader do nothing for years.

While this does seem to be a more streamlined, less awkward system than what was present in CK2, it is a bit disappointing to see that factions are still only single-issue entities and that they remain completely oppositional as well. Feels like a lot of interesting opportunities have been missed out here... Excited to finally see the revamped religion however! Hopefully it's a bit more substantial in its changes than factions and governments have been.

some question :

About populist and peasant faction :

Do you have to deal only with counties you have directly ? Meaning counties rules by vassals can't join a faction against you ?

If no, do vassal who rules counties which have joined a faction will automaticaly join this faction too ? If no what happen if the faction win and your vassal didn't joined this faction, does he lose his counties ?



And last, do vassals who didn't pleged the faction will join you to defeat a civil war or just lurking at you like in CK2 ?

Province factions are a very nice improvement from the current model.

Do tributaries still exist in CK3 (hopefully!), and if so, do they now get to interact with (presumably independence) factions against their suzerain as well?

Aren't hooks becoming too much of a universal cure for every problem a ruler could have? Why should hooks prevent someone from joining a faction?

For starters, any alliances you have made with your vassals will prevent them from joining a Faction against you. This makes arranged marriages within your realm valuable even if you don’t benefit as much militarily as you would from a foreign marriage.

Adding to this, any vassals you have a hook on will be unable to join a Faction against you, whether that hook is due to them owing you a favor or due to blackmail.
If you somehow manage to get a marriage alliance with or get a hook on a rebellious vassal mid-revolt, can you persuade them to defect from the rebels and come back to your side, against the revolt?

EDIT: Actually, the way you worded it makes it sound like it only prevents them from joining factions. Shouldn't they also leave any not-currently-revolting factions that they currently are a part of?

While an Independence Faction causes all members split off into their own separate realms, a Populist Faction will create a single realm with all members united under one ruler. That ruler will always share the Faction’s culture and religion, and as a hero of the liberation war they will almost always be a competent commander. In addition, a successful Populist Faction will automatically usurp or create an appropriate title for their leader to hold, which can even generate new Kingdom-tier titles in certain circumstances!
Interesting, a populist Faction has a potential to cause a major headache.

For starters, any alliances you have made with your vassals will prevent them from joining a Faction against you.
Is this hard coded to be the case? There were plenty of cases of vassals related to the throne by marriage still deciding to go against their in-laws. Or is it possible for a vassal to break an alliance if properly motivated to move against the crown? I'm not sure I'm fond of the idea of gaining internal stability at only the expense of "opportunity cost" of marrying a daughter or sister off to key powerful vassals.
Unlike in CK2, when a civil war is declared faction members do not form a new temporary realm. While they nominally remain vassals of their liege, they will immediately stop providing taxes and levies to them, and their liege will lose access to certain powers (such as imprisonment).
Excellent! CK2's temporary realm mechanic was a little clunky, especially with the way title tiers played with marriage mechanics, so a temporary emperor would suddenly have an artificial prestige for marrying off relatives. Glad to hear this has been done away with!
