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.

So this is just placing the golden bull of 1356 six centuries earlier? I definitely like the idea, but I feel like a "number of electors" slider would be more appropriate for the HRE. It wouldn't be that difficult to throw in, and it shouldn't be too difficult to centralise the electoral lands: powerful dukes/kings that stand to gain most from the policy should be in firm support.
 
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.
Like a Katepano (someone who held several themes back in the day)? Sound great and historical to me.

The Golden Bull of 1356 did not create the system, it merely confirmed the status quo that has been for centuries. You can search it in this thread, we've already discussed this to an end. It's been debunked.
 
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?

If you want to get a test taste Merchant Republic also have this limitation. It just means that other governments cannot actually grant you kingdoms, which if you're an independent emperor is very unlikely to happen anyhow. You're the one giving them out after all. Inheritence is still on the table.

That being said not being able to usurp titles is a minor annoyance at best. The only time it actually is a bother is when you're trying to usurp empires, and by that time it's probably best just to vassalise the pope for a bit, go catholic, and get him to grant you claims to every county in the opposing empire. He'll hate you, but it allows you to easily gobble up the entire kingdom in one big bite and recreate the title if you want.


QUESTION: I don't know if this has been discussed, but if I mod in a succession with only 1 candidate (to create my own succession laws) who will become pretenders? Does the game actually calculate who might have been 2nd and 3rd in line and grant them their claims or is it just children of the ruler?
 
Like a Katepano (someone who held several themes back in the day)? Sound great and historical to me.

But how will viceroyalties be handled by the AI now? Currently, when a strategos dies the title goes to the exarch. The issue is that they never hand it back out and incure the "too many held duchies" opinion penalty. This alongside the exarch mass revoking county titiles because they hold the Theme for it, causes constant civil wars in their province.

Also, if you are emperor and hand out an exarchate, die, and your heir was not elected to be the new emperor, does that viceroyal title revert back to you or the new emperor? Do you keep all viceroyal titles that reverted back to you?

Also I am curious how this will be handled even if you are the Emperor, since the the rules of the imperial government state that the emperor cannot recieve any kingdoms/empires from other rulers of different government type. Does this mean that the Roman emperor wont recieve the viceroyal kingdoms he gave out, once the viceroys die?

I assume in this case it would be an exception?

I hope the devs can answer this question before I start my Roman Empire play.

____________
On the side note. I dont agree that like some people have mentioned that the heir designation for hellenics will useless due to the Imperial government.
I for example like to keep a kingdom tier title for myself with dejure vassals (including merchant republics) alongside the Emperor title. I find that this will be even more important due to the imperial elective mechanic, since there is a chance that you could loose the empire and become some backwater count/duke with people hating cause you have lands in their dejure titles and not able to afford your retinue. Instead of this scenario you become a powerful figure in the empire you could easily take back the throne by force or through succession.

The heir designation mechanic will ensure that if your heir will become emperor that he also inhirits the kingdom tier title, instead of your kindom passing to some other relative.

Would it be possible to tie retinues to succession law so there inherited by whoever is elected?
 
With the limit on usurping kingdom titles could you make it possible to transfer vassals to a non-de iure viceroy? Eg if I give a titular viceroyalty it would be nice to assign some existing counts/dukes as vassals.
 
Also, if you are emperor and hand out an exarchate, die, and your heir was not elected to be the new emperor, does that viceroyal title revert back to you or the new emperor? Do you keep all viceroyal titles that reverted back to you?

I am fairly certain that Silfae already said that the limit is on being granted titles, not on inheriting, creating, or taking in war.

Yes that is understood, but who gets the viceroyalty if you lose the "election"?
 
It reverts to whoever is the current liege of the viceroyality (if I recall), which would be the new emperor I'd imagine.

That is what I think too. But this would require that the AI always hand the title out as a viceroyalty or else when they die, their heir will inherit it and you could end up with a non-viceroyal vassal.

The new government only precludes the Emperor from usurping Kingdoms, it does not prevent a ruler from inheriting, creating, or revoking them.
From Imperial gov tooltip: "Can't receive kingdoms and empires from character with a different government".
I don't understand what that means. We have other tooltip about usurpations.

That not entirely true. The Prince-Electors most likely developed from a smaller group of prominent prince (Ecclesiastic and Secular), which were tasked with the necessary preparations for an election, being there first they often were able to make a (pre-)selection of candidates. The other Princes (Upper nobility, which were immediate vassals of the monarch) could still cast their vote. In the period from 1125, 1152 to 1198. The double election of 1198, when a Hohenstaufen (Philip of Swabia) was elected by one group and a Welf (Otto of Brunswick) by another, it was after the failed attempt by Henry to make the kingship hereditary. The changes gradually started in the 12th century. It only started to solidify a bit later, the Electoral College is mentioned by Pope Urban IV in 1265 (it refers to the election of 1257), then of course there is the declaration of Rhense (1338) and finally the Golden Bull of 1356.
1257 seems to be the year, when the Prince-Electors finally were able to make the election of the monarch their privilege.

As a side note the original Secular prince-electors represented the four German tribes, so the Franks (Franconia/Palatinate), Saxons (Saxony), Bavarians (Bavaria) and Swabians (Swabia). Bohemia, especially once it becomes a kingdom could replace either Swabia or Bavaria, but it seems unlikely that an existing duchy of Swabia would be replaced by Brandenburg. This becomes an in game issue with the electoral college (with 7 members) being implemented before 1257.

Hence that I suggest, that before this point more Princes of the HRE should be allowed to cast their vote, but not all of them. IMHO places like Upper Lotharingia (Lorraine), Lower Lotharingia ((Lothier), Brabant, (Limburg)), Carinthia (might at one point be replaced by Austria), in game Frisia (Gelre or Holland, though perhaps only as a kingdom), maybe Thuringia, the Saxon Eastern March AKA Gero's march* (Brandenburg*, Meissen, Mecklenburg*) and the other arcbishoprics Salzburg, Magdeburg and Hamburg-Bremen. All in all my suggestion would make for 6 ecclesiastic princes and 11 secular princes, this would give 17 'early' Prince-Electors, in comparison by 1190 there were 22 secular princes and 92 ecclesiastic ones. My proposal would still limit the number of electors, there are IIRC 22 creatable duchies in the in game HRE, having a maximum of 11 secular voters for the early HRE seems IMHO reasonable.

(*= established in 939 and partially lost after the Great Slav rising of 983, only to be regained at a much later date).

Edit: as mentioned later some of the voters, IMHO the early 7 (the archbishops of Mainz, Cologne and Trier with the dukes of the Franks, Saxons, Bavarians and Swabians) and the later 7 (the familiar ones, so the archbishops of Mainz, Cologne and Trier, the king of Bohemia, the Count Palatine by (of) the Rhine, the duke of Saxony (Saxons) and the Margrave of Brandenburg) should all get a higher voter_power, than the rest. The rest could either be a limited group as in one representative for a certain region, or every existing duke. This IMHO could similate original role the early Prince-Electors, all with ceremonial archoffices in the Imperial-Royal household had in the elections.

Well not quite. Like they said, you only get the Prince Electorship succession when you form the HRE through the proper channel (Charlie can do this). If you use the "form early" button you don't get this succession type. And of course, later starts also get the golden bull system.

In practice, it's more like 3 centuries earlier since I assume the 1066 start HRE will get the new system. It's a little less anachronistic for them though, since by Henry V's time prince politics were definitely a thing, even if electorship was not.
 
It means that characters with the imperial government cannot be granted kingdoms or empires from characters with different government.
Curious if it even matters. The byzemperor has no liege. Who would grant him a title? I wonder if that's there because they are planning to use that government type elsewhere too.
