CK2 Dev Diary #106 - New Succession Laws Extravaganza

Greetings, everyone.

Well then, this is going to be a long one...

The old elective succession system has been succeeded


So your cousin the Duke of Burgundy always seem to nominate the Steve ‘the drunkard’ as the next Emperor of the realm rather than your favorite quick and attractive son. This has been a common theme for a bunch of our playthroughs while having the elective succession laws active for our main titles. One of the biggest problems about this is that the other electors reasonings for their nomination decisions has been hidden away in an opaque box so you never know which electors can be influenced to see things more in your way.


This was one of the first problems we wanted to address when we decided to rework the elective succession system. So instead of just giving you a list of names in the tooltips for whom casted votes on a given candidate we made a specific interface to enable us to give you a more detailed view into the minds of the powerful electors of the realm.

After it was possible to get a better look at why the electors made their decisions we wanted to make it easier to further edit the underlying factors which governs the AI. Therefor we decided to replicate the old logic from hardcoded conditions to instead be based on a scripted system which decides various rules of how the elective succession works.

This not only enables modding of the elective succession law, we now also allow you to create any number of your own elective rules to fill the world with different electorates that play by their own criterias. Maybe you always wanted to create your own technocratic republic that is governed only by the most learned people of the realm. The party realm might only allow drunkards and hedonists to have a say in whom should be this years party host.

For the people that are more interested in exactly how this is modifiable there’s a brief rundown of the syntax used to define the elective rules here:

Code:
### Condensed syntax layout:

#<elective_law_type> = {

#    candidate_vote_score = {

#        <Weight Modifiers>

#    }

#    elector_selection = {

#        max_amount = <int>

#        <Weight Modifiers> - if max_amount is set it will pick the X amount of top scorers.

#                Negative scores are considered invalid electors - Ruler is always an elector

#    }

#    elector_vote_strength = {

#        <Weight Modifiers>

#    }

#    elector_stances = { - Intended for the elder council positions

#        <stance_name> = {

#            icon = <int>

#            <Weight Modifiers>

#        }

#    }

#    candidate_trigger = {

#        <trigger>

#    }

#}


# <Weight Modifiers> - denotes a field of an arbitrary amount of triggered value modifiers eg.

#    additive_modifier = {

#        value = -4

#        is_tribal = yes

#    }

#

# <trigger> - denotes a field of conditions that needs to be evaluate true for the trigger to be fulfilled

#

# The elector will vote for the candidate with the highest score given by candidate_vote_score

# The electors are selected from the pool of characters which get a non-negative elector_selection score until we reach the max_amount

# elector_vote_strength will determine how much weight the vote of a single elector carries

# The elector will use the elector_stance with the highest score if any are scripted

# The stances are thought to be some kind of common thought process or allegiance for a subgroup of the electors - This system is used to create the different states for how the Elders will behave in the Eldership succession law explained in detail below

In addition to these underlying code changes of the elective succession forms we also added another usage of the Conclave favors so that you now can force electors to vote in compliance with your vote for the succession of a title.

Revamped Elective Laws


The unhardcoding of Elective successions allowed us to completely rewrite the AI behavior for the existing Elective laws accessible through the base game (Feudal Elective, Elective Gavelkind, Tanistry). The various conditions to be eligible as a successor or elector under these laws have remained unchanged (although now they have been translated into moddable script), while the AI electoral behavior has been rewritten into a long list of nuanced modifiers. You can now expect Electors to take into account how much they like a candidate, how legitimate they think his claim his to the title, and how much they trust the ruler that is voting for said candidate. Age, titles, character traits, culture, religion, dynastic ties and much more are now all taken into consideration by the AI and visible to the player when using the new Electors’ Tab. The sum of all these modifiers will result in a voting score, and the potential candidate who has the highest voting score will be the one selected by the Elector in question (and since each Elector has a different personality/status/etc. different kinds of Electors will prefer different kinds of candidates).

Succession Laws1.jpg



The Electors Tab shows to the player the complete list of Electors casting their vote, who they are voting for, the reasons why they are voting for said characters as well as a comparison with the candidate score of the ruler’s preferred candidate and the reasons why they are not voting for him.

Eldership

Somewhat similar to Tanistry, Eldership prevents your title from ever falling outside a ruler’s family, restricting the choice of potential candidates to members of the ruler’s dynasty. Under Eldership, only the six oldest and most learned characters in the realm will be allowed to pick the ruler’s successor. Each Elder can hold one of three possible stances at any given time, depending on how he feels about the ruler: Displeased, Pleased, or Ecstatic.

Making sure that your Elders have a high opinion of you, giving them their preferred Council positions (Chancellor, Steward, Chaplain), or fulfilling the occasional request from them, will push them further to become Ecstatic.

20180824080508_1.jpg


An Ecstatic Elder will almost always vote for the ruler’s chosen candidate, almost never make demands, and even give the occasional piece of advice to make you a better person.

20180824080639_1.jpg


Pleased Elders will try to vote for what they consider to be good and capable candidates amongst the members of your dynasty, favoring older characters with high stewardship. They might occasionally make some demands, such as asking a ruler to give some land to a family member that they really like, but they will, for the most part, be reasonable people to deal with.

Displeased Elders on the other hand, will be much harder to deal with. Not only will they purposefully select bad candidates, they will occasionally grant claims on your title to people that they like, openly questioning their liege’s right to rule.

20180824080819_1.jpg


Holy Fury will allow the Baltic and African realms to start with Eldership as default succession law, rather than Elective Gavelkind. Additionally, other pagans can unlock this succession by picking the right Doctrine when they Reform their faith.

Princely Elective
This new variation on elective has been scripted to replace Feudal Elective for the Holy Roman Empire. This succession limits the electors to a maximum of seven (plus the ruling Emperor) and makes it so the historical titles held by the Prince-Electors are prioritized when determining the valid electors in the Empire, these titles being the Bishoprics of Mainz, Koln and Trier, and the Duchies of Bohemia, Franconia, Saxony, and Brandenburg. If an elector title does not exist or his held by the Emperor, another valid Duke will replace it (prioritizing dejure vassals of the same religion as the ruling Emperor).

20180824081547_1.jpg


Electors under Princely Elective are overall much less likely to pick candidates that are either impious or of a different religion, and Theocratic Catholic Electors have twice as much voter strength than secular Electors whenever the Empire is under Papal Investiture.

While rulers of the Holy Roman Empire can still change the realm’s succession law as usual, the faction for Elective has been made much more easily accessible and palatable for vassals of the HRE and requirements to switch away from this succession have been made more restrictive (the ruler must have Max Centralization and either Absolute Crown Authority or Abolished Council Power).

Imperial Elective
And finally, a completely new succession law has been scripted for the Byzantine (and Roman) Empire, to better represent the peculiar politics of this realm. This succession has been tied to the two titles and is now also the *only* succession law that they have available. There are several features that are unique to this succession law, so I will explain it in sections:

20180824081910_1.jpg


Successors: Potential candidates under Imperial Elective include the Emperor’s children and close family members (spouse included), any claimants to the title, the current Marshal, and any Commander under the Emperor, with mutilated characters being excluded. This is to represent the influence of the military over Byzantium and allow more historical instances of influential commanders becoming Emperors.

Imperial Court: The Emperor, all of his Councilors, and all of his Commanders are valid electors. As Byzantium was a centralized power, the Emperor will need to curry the favor of the most powerful members of his court to ensure that his dynasty continues to maintain the throne, rather than his vassals, like a Feudal ruler would.

Scaled Voting Power: And this is where things get really interesting. Imperial Elective uses to its full extent the new voter_power function of scripted elective, making sure that every elector has a different amount of influence, entirely dependent on his status in the court and his attributes. The Emperor’s vote starts out with a strength of 200 voting power, which can be further boosted by good diplomacy and martial scores, making it so that a powerful and influential Emperor will be able to push the candidate that he wants on the throne even if most of the Court is against it. Conversely, if the Emperor is not Born in the Purple, deformed or crippled, or if he has made a reputation of appointing sycophants in his court (more on that below), he will see his voting power plummet. The other Electors have their own variable voting power, tied to prestige, rank and attributes (a Steward with high stewardship is more influential than an incompetent one). As such, appointing competent people to be your councilors and commanders will not only mean that your favorite son will have to compete with more competent and palatable candidates, but also that the electors will have a greater influence over the succession. Finally, minor titles can also affect a character’s voting power, so you might want to think a bit more before giving out your Caesar and Sebastokrator spots.

20180824082114_1.jpg


Heroes and Sycophants: Is Belisarius too popular a Commander for your sons to compete with him? Well, you can always discharge him: take away his status as Commander and he will no longer be a potential candidate or an elector, problem solved. Except... when under Imperial Elective, removing a competent Commander or Councilor from his position reduces the Emperor’s voting power of an amount proportional to the competence of the character you are removing. The more competent people the Emperor pushes out of his court, the less his vote will be worth overall. Same applies whenever an Emperor appoints a commander with poor martial score while there are clearly superior choices available: the court will notice that you are appointing mediocre sycophants because you fear competition and you will see your voting power go down. Additionally, Imperial Elective prevents Emperors from appointing landless commanders for as long as potential vassals are available to take the spot. If you wish that high-martial courtier to lead your armies, you will need to give him a proper title first.

Prestige and Ageism: This is not Feudal Elective, the Empire does not care as much about family ties and character traits, it cares about placing a competent and prestigious leader upon the throne. For the Byzantine Empire, this translates to the electors tending to favor skilled high-Intrigue characters, whereas the Roman Empire electors are keener on good orators (high Diplomacy). In both Empires, the electors will always favor people that are competent at their job, that have high prestige and titles (both minor and landed). One of the most visible consequences of this is that hardly anyone under Imperial Elective will ever consider a child to be a valid successor to the throne. If you wish your son to take your place, you will have to groom him first, wait for him to become adult, then push his bid to your Empire, possibly giving him a few honorary and landed titles along the way. While he’s still a toddler, it might be more sensible for you to appoint your younger brother, or your old uncle as preferred heir, just in case something happens before the little Prince comes of age...

20180824082155_1.jpg


Strong Claim Duel
Somewhat related to all these new succession forms, we have also added a new type of duel designed to let players keep their realms together after an Elective Gavelkind succession. This Strong Claim Duel is available regardless of whether you have the War Focus active, or if you are a member of a Warrior Lodge (which is otherwise required for regular dueling). As a tribal character, with a Strong Claim on a title currently held by a tribal ruler, it will be possible to issue a challenge to the current title holder, with the requirement of your target ruler either being independent, or both of you being vassals under the same liege. Bear in mind that the stakes in these duels are high, and losing does not only mean you give up your claims - unless you have a particularly kind opponent, who loves you dearly, death is the common way out of this dispute. Winning, on the other hand, means that you take the title in question and any vassals that come with it, along with any other of their titles on which you have a Strong Claim.

If the target of your Claim Duel happens to be an AI character of your own Dynasty, losing will present players with a choice: accept your fate, or click the option to take over as the character who won the duel, and continue to play the game as the kinsman (or woman) who bested you.

If imperial government can’t usurp kingdoms, then the only way to conquer another kingdom is to press a claim for the kingdom, declare a great holy war, or conquer the kingdom duchy by duchy or county by county until you conquer the entire de jure and de facto kingdom, whereas before you only needed to conquer the majority of the de jure kingdom and then usurp the title. In other words, you would need to destroy the kingdom and then create it anew. Such conquests can get dragged out over decades, especially if the king controls holdings outside the de jure kingdom. This seems like an anti-blobbing measure specifically for the Roman empires.

It essentially makes a viceroyal roman empire impossible, you'd be insanely over the vassal limit and even using superdukes each time a superduke dies its a huge opinion malus.

The new government only precludes the Emperor from usurping Kingdoms, it does not prevent a ruler from inheriting, creating, or revoking them.

Can't we have dynamic "usurp - rules", could it not be possible enable usurping at 100% controlled De Jure instead of 51% for this goverment exclusively? And does this not promote usage of the gamerule that destroys duchy and above titles if no dejure title is controlled? to not be able to usurp an infidel kingdom when you have 100% of it´s dejure is abit dumb :)
 
I'm worried this got lost over the weekend so i'm reposting it minus the parts that already got answered.

"priests of that religion's holy sites" this condition might be beyond the scopes that a title can reasonably check for when determining its electors. Though the system could allow to make priests within your dejure or defacto realm that own a holy site be electors
-can you limit potential heirs to electors only?
-can you limit electors to title religion only?
-can you limit electors to specific government type only
-can you have an arbitrary number of electors?
-can you have multiple levels of elector priority (possesses holy site, then king rank, then duke rank, ect...)?
I'm not sure what you mean with "abdicate old titles upon inheritance".
like the pope does. upon inheritance they give their current title(s) to their heir and receives the titles they're inheriting separately.
 
Some thoughts on the new Byzantine succession from a Byzantinist in formation:
  • My main issue with this new features are the elements involving landed titles. It makes absolutely no sense making commanders landed-only characters. This is not only historically inaccurate, but completely contradictory to the spirit of the new imperial government. Commanders should be landed characters in feudal societies, since feudal lords were the military commanders all the time. There should absolutely be no requirement for a Byzantine commander to be landed. It represents the opposite of a centralized government and military hierarchy. This is only made worse by counties still being unrevokable without just cause.
  • Similarly, the apparent need to land your favorite heir is counter-intuitive and contradictory. You want your heir to be at Constantinople when you pass away, not far away in the provinces. You want to retain control of his household. An heir ought to be landed in feudal polities, not under imperial governments. It’s the opposite.
  • Finally, I’d recommend switching the Caesar title to Co-Emperor (Symbasileus), which was the actual way power was transferred in Byzantium most of the time. Caesar works for early game, but by mid and late game it’s an outdated title which is outranked by other court titles, including the in-game Despot and Sebastokrator ones. And yes I realize the irony given my username :p
  • Which brings me to one last point: succession was rather automatic in Byzantium due to the Co-Emperor mechanism. It’s not selecting your heir and having him succeed that was the problem. The problem was consolidating the succession. Ideally imperial succession would allow you to pick your heir and have him succeed you, but if he’s not the electors’ favorite heir, according to the new mechanics, he could either be deposed by a palace coup, a popular revolt at Constantinople or a good and old succession war.
In short I believe the new imperial succession to be a very good evolution from the previous system, but it’s very flawed. It forces on us elements of feudal government that aren’t even present in in-game feudal governments (e.g. landed commanders) and it misses the point of succession. It’s a step in the right direction, but there are still more steps to take (such as popular sovereignty) and some to undo. If that’s not possible for the CK2 team in future patches (and I would totally understand it), I leave this post as a suggestion to modders, especially HIP. Cheers!

I very much agree. The commander change is the one thing that feels like a huge step backward and is bad enough that it seriously makes me reconsider wanting to even bother with the ERE and Rome, and lately, that has been my favorite thing to do. It reminds me of the really old rule where you couldn't choose commanders at the lowest law levels. The push to make you land your heir is just as bad. You are very correct that both of those are very feudal ideas that do not fit this rework at all. Hopefully they either abandon the idea or at least patch it out when it becomes obvious how bad it is.
 
"Common people" are not handled in CK. How is it democracy just because all landholders get a vote?

And IF we should have "every landholder can vote", I´d prefer it beeing completely dejure based and not "defacto" based.

I would like to see this "Feudal Elective Monarchy" where all dejure landholders has a vote. And using the new value for what a vote is worth would be cool. if a lord actually gets voting power from each dejure title held :)
I mean every person in the realm, not only landholders. All people titled and courtiers have a vote. But only to have that option if you mod it, not in the vanilla game, as it is not historical and could be quite performance heavy.

Yes.

Not directly, it might be possible to simulate something similar with hidden events.
 
Good work on this amazing revamp of the succession law, but one question. With the Imperial Succession Law. They will for sure not vote for any kids? like even if you have a son as an emperor born in the purple? Also when you say that your vassals perfer more intrigued characters in the byzantine but when you have the roman empire they perfer more diplomatic characters? Does it matter to a degree dependent on if you play as the byzantine or the Roman Empire?
 
I might get a bit creepy but I can't stop thinking of the new ERE succession and government:D
It's so awesome to me.

It actually makes me want to be a vassal, help safeguard the empire and help the renaissance to happen.

It makes me want to be a Roman citizen and proudly so.
This is of course just my opinion, but thank you devs... These ERE and RE (even hellenic sounds fun, though i'll secretly remain christian;)) are like a lullaby to my sleep and a serenade to my heart.

Big kisses to all the team from Italy. :p
 
Kids as in literally children. They want adult rulers. So when your son grows up he might get elected. Otherwise an adult relative might be a better choice
I see, So I will have to have my brother or something instead then. In that case, in this certain succession law, does the pretender negative opinion modifier still there along with the negative opinion modifier of them being your brother or half brother still effect opinion is the question (I think this would only affect Feudal Succession elective and not imperial maybe?)
 
The new government only precludes the Emperor from usurping Kingdoms, it does not prevent a ruler from inheriting, creating, or revoking them.

Sorry to be both that guy and a pain but doesn't that sort of contradict the "cannot receive kingdoms or empires from other government types" in the description?
 
You all at paradox have really outdone yourselves for this DLC and patch! I may not actually expand at all with the ERE/Byzantines because I will be having so much fun roleplaying politics! This also now makes it more fun to rise up the ladder as a lowly bureaucratic count and eventually become Emperor by being elected! My only concern that has been echoed by others is how viceroyalties will work now. Since you cannot usurp kingdoms, you have to conquer 100% of the territory and wait till the holder of that title dies before the title gets destroyed and you can then create it and hand it out as a viceroyalty? This would indeed require the creation of super strategoi that hold three or more themes.

There goes my tactic of packing my Council with out of country lackeys teary eyed with gratitude for their sudden ascension from their lowborn state...and murd...er..."replacing" all of my previous vassals who so much as looked at me cross-eyed to be replaced by feckless lackeys who didn't even speak the native language of my lands.
 
Belisarius....a good start at 500 AD or thereabouts should be a lot of fun! Then a mod for the alt-history of Drake and Flint soon after that. Either way suppressing the Nika Revolt would be a real thing to worry about unless you happen to have some spare Cataphracts handy. Either way a tactical and strategic genius like Belisarius showing up should spook any Emperor. And if an Emperor doesn't meet the rules for being capable of ruling, then worrying about diseases or maiming in battle becomes a great concern. Yet you are still expected to be competent and brave. Good luck on that! Hope you kept the powerful families well bribed. Or at least so jealous of each other that they pay more attention to their own plots and less attention to the Emperor: Byzantine politics at its finest.

After that, well, maybe implement The Thing for Nordic rulers in which proposed changes to the law can only be done during the gathering of Lawspeakers from every county, which would get rid of the Council for such things though leave them for administrative duties, and make changing laws much, much harder. Pretty hard to bribe all of them which then means being a decent King. Of course you do get to appoint one Lawspeaker, so it had better be someone good. Who knew that finding someone who was a good scholar and a good diplomat as Lawspeaker would be so important? That would be an interesting change to the game.
