Europa Universalis IV - Development Diary 31st of May 2022

Hej allesamen! Welcome to our next Development Diary for Europa Universalis IV! After covering the Baltics it is finally time to switch our focus to Scandinavia, so let’s get started!

As the 13th century drew to a close, powerful social mechanisms such as feudalism and manorialism had formed deep roots in the Danish Court. At the same time, the Christian church had, at that point, come to dominate religious matters all across the Scandinavian region. At home, the royal family, spearheaded by Margaret I, would finally place a singular dynastic head on each of the three lions’ thrones, during the last years of the 14th century.

As of the treaty of Kalmar in 1397 the Nordic Crowns of Norway, Sweden and Denmark are intended to be borne by one monarch. Since its inception this Kalmar Union has been led by the Danes, the strongest and richest of the Nordic powers, close to the continent with an ambition to control and dominate the Baltic Sea area.

Eventually however, the Kalmar Union fell apart when Sweden broke free from Denmark and established an empire of its own later on. The goal of the Danish mission tree is to avoid this fate. It also focuses on the ambitions Denmark had during the time period of EU4 and as such is a lot less experimental than the Teutonic and the Livonian Orders’ mission trees.

You will notice that the Danish mission tree is separated into two “blocks”. The first half is about keeping the Kalmar Union together with a few conquest missions on the side to ensure that Denmark is the sole maritime power in North Europe.
The second block on the other hand is a lot more about the Danish ambitions of colonialism, the question of religion, embracement of Absolutism and the usage of mercenaries as the army for Denmark.

We will focus on the Kalmar Union block first as it ties into the mechanics which are unique to Denmark with the upcoming DLC. When you start as Denmark while the DLC is active you will be confronted with this government reform at your start:

The Kalmar Union is a somewhat mixed bag for the player. On the one hand, the diplomatic relations and possible advisors are desirable to have, but on the other hand you are confronted with the fact that you can not manually integrate any kind of personal union (however, inheriting them is still feasible though). You also have to deal with the “Kalmar Election” which is a unique mechanic to Denmark.
As you might know neither Sweden nor Norway had a hereditary monarchy but an elective one. So whenever your king dies as Denmark while you have this government active you get the following event:


This will trigger the following event for your Scandinavian personal unions:

It is important to note that the AI will make their choice based on your prestige, diplomatic reputation and how much Liberty Desire they have with the latter one being their biggest factor. As Denmark you really want to keep the liberty desire low of each of your personal unions or otherwise they might spiral out of your control and will easily find supporters for their independence.

While the first and third options are rather self-explanatory, the second one is a choice that the AI can take when they are not fully convinced by your ruler - mostly when your ruler is quite the unfortunate one regarding his monarch skills - but do not desire to break out of the Kalmar Union yet. In this case the junior partners can suggest somebody from their own ranks to take over the Kalmar Union as your king:

This will of course trigger an event for Denmark where they can accept or reject to proposed regent:


Of course you can always reject the proposal, though this will result in your junior partner becoming slightly upset about your decision. Alternatively, you can accept the new king, but because your junior partners have to elect their king this will result in a new re-election:

However, this event will not allow your junior partners to propose another new king (otherwise you would end up in a loop of elections of new kings while hilarious for the first three or four rounds can become quite annoying really fast). Additionally, the one who suggested your new king in the first place will ALWAYS elect him to king, so you can reduce some liberty desire this way.

While the Swedish and Norwegian nobilities are a pain to deal with, you cannot forget your own. Historically, the Danish nobles did not support the Kalmar Union and attempted to exploit the divided attention of the Danish King. This gets represented in form of an event which triggers around every four years:

There are 11 demands in total and the nobility will pick one of them. Each one of them has some penalty to your country: be it from losing monarch power to losing Ducats to even getting the risk of a hunting accident.

Now let’s go back to Denmark's mission tree. The centerpiece of the mission tree focuses on resolving the conflicts with the other junior partners. By increasing the opinions of your Norwegian and Swedish subjects you can complete the missions “The Crown of Norway” and “The Crown of Sweden” which give you the following events respectively.

The first option allows you to receive a penalty to National Tax Modifier / Goods Produced Modifier by -10% and an increase of the Nobility’s Influence by +10%, but in return your two subjects gain a modifier which decreases their liberty desire by 10% and increase their Yearly Tax Income, which makes them to durable subjects during your wars with other European countries. The second option just gives some monarch power. On the other hand there is the third option which allows you to be more risky with your personal unions, giving the following effects:

Note: keep in mind that numbers and modifiers are NOT final.

The “Integrate Holstein” mission is rather self explanatory. However, “The Nobles of Sweden” is a little bit of a different story:

This whole mission is basically about a medium-long event chain (which also incorporates some of the vanilla Danish / Swedish events into it) where you can choose how to deal with the nobility of Sweden. For the sake of simplicity I will only highlight the two possible results of the event chains:


The event for Sweden when Denmark chooses to be more hostile...

After dealing with the Swedish nobility (by either defeating them on the battlefield which is Sweden or by executing them in quick succession in Stockholm), you can start working on the “Ratify the Kalmar Union” mission which triggers the following event for you:

Note: Modifiers and mechanic values are subject to change.

Keep in mind that you get this event ONLY when you complete the “Ratify the Kalmar Union” mission while having the Kalmar Union government reform. Otherwise you get +100 Monarch Points for each category. The military bonuses mentioned here are the following ones: you gain flat +2000 Manpower and +400 Sailors per Junior Partner + an additional +5% Global Manpower Modifier and Global Sailors Modifier. Meanwhile, your junior partners will receive the military benefits of Marches, so keeping them as your military buffer states.

You also unlock one decision which might be welcome to any roleplayer here:

Historically, only Christopher III von Wittelsbach styled himself as “Arch-King” while everyone else in Europe just used the normal title. In a time where Cristopher and his heirs might have managed to keep the union together it seemed plausible enough to us that future generations of Danish rulers might choose to follow Christopher’s naming fashion. It is, however, a purely visual title and you gain no other benefit than having an unique title.

Now that we are done with the Kalmar Union section let’s take a look at the remaining missions of the first block. The most right side of the missions are quite obvious what they are about: challenge the English navy, conquer England and gain dominance in the British Isles. These missions are referencing the North Sea Empire, but the mission descriptions make clear that the conquest of England is motivated by maritime rivalry and commercial dominance in Lübeck and the English Channel, not by the lost accomplishments of the Danish vikings centuries ago.

The most left branch of the missions is more concerned about a more important enemy Denmark is facing: the Hansa. Some of you, the community, already commented how the poor merchant republic of Lübeck gets bullied in this DLC and Denmark’s mission tree continues with this trend. The mission “Humiliate Lübeck” unlocks a decision for you which will be very much needed for the next mission:

The mission “The Cities of the Hansa” will require you to control all the important centers of trade in the Lübeck trade node - all lands in the HRE. Because of that, you will most likely know to appreciate this decision as this will trigger a DEFENSIVE war against the Hansa.
The rest of the mission branch is then about conquering Estonia and Novgorod and of course expanding the Sound Toll. Highlight here is a permanent +25% Trade Efficiency modifier.

Now that we are done with the European affairs part of the mission tree it is time to go into detail for the second block of missions. The missions linked to “Colonial Ambitions” are the biggest branch of this mission tree and cover the colonial ambitions of Denmark with a big focus on colonizing valuable trade company regions and a lesser focus on the New World (which also gets updated if you happen to play with a Random New World).

The second biggest branch of the flavor events are the branching missions on the most right. These are focusing on the religious direction of your country: stay loyal to the Catholic Church, embrace the Reformation or become a state of Tolerance. Completing the mission “The Age of Reformation” fires the following event which unlocks your religious missions:

One notable mission from the religious ones are the “Spread the Reformation” / “The Religious League” missions which you unlock by either taking Reformation or Catholicism missions respectively. What makes them special is that they are intertwined with the Religious League War. You complete them by winning the Religious League War and the mission rewards you with +2 Military Skill for your monarch and +150 opinion of every HRE member which follows your religion, which makes becoming the next Emperor of the HRE more feasible.

One minor but important branch I want to go into detail is the one regarding the mercenaries. As some of you might know, Denmark is not really known for its own strong military during this time period. Instead of Danish soldiers, the kings of Denmark relied heavily on German mercenaries to do the monarchs’ bidding. The mission “The German Mercenaries” emphasizes it. By improving the opinion of several owners of homes of Germanic mercenary companies you can complete this mission and the following event fires for you:

The mercenaries you unlock are dependent on which owners of Germanic merc company homes have a high opinion of you. In this case Denmark increased the opinions of Saxony, Hesse, Wurttemberg and Switzerland.

And that was the Danish mission tree!

As we were working on the Danish mission tree the time for us has come to also revisit the Danish ideas. While the kingdoms of Norway and Sweden have unique and/or very powerful ideas, the Danish ideas fell flat on both fronts. We wanted to change this for the upcoming update and as such we decided to give Denmark an update:
DAN_ideas = {
    start = {
        navy_tradition = 1    #Prev: ship_durability = 0.05
        global_manpower_modifier = 0.2    #Prev: global_tax_modifier = 0.1
    bonus = {
        global_naval_engagement_modifier = 0.15    #Prev: global_naval_engagement_modifier = 0.10
    trigger = {
        tag = DAN
    free = yes      #will be added at load.
    dan_kalmar_union = {    #Prev: shock_damage = 0.1
        liberty_desire_from_subject_development = -0.2
        diplomatic_annexation_cost = -0.1
    dan_sound_dues = {
        global_own_trade_power = 0.2    #Prev: global_manpower_modifier = 0.2
        trade_efficiency = 0.05    #Prev: global_sailors_modifier = 0.2
    dan_the_kings_sea = {
        naval_forcelimit_modifier = 0.5    #Prev: naval_morale = 0.1, disengagement_chance = 0.05
    dan_royal_mercenaries = {    #Prev: build_cost = -0.15
        shock_damage = 0.1  
        mercenary_discipline = 0.05
    dan_naval_heroes = {    #Prev: naval_maintenance_modifier = -0.15
        leader_naval_shock = 1
        naval_morale = 0.15
    dan_colonial_ventures = {    #Prev: naval_forcelimit_modifier = 0.5
        global_colonial_growth = 15
    dan_danish_absolutism_idea = {    #Prev: global_unrest = -1
        global_autonomy = -0.05
        max_absolutism = 10

While we were updating the ideas of Denmark we also remembered another favorite of the community whose ideas were rather lackluster - even for its time back then:
VEN_ideas = {
    start = {
        trade_steering = 0.33    #Prev: global_sailors_modifier = 0.20
        republican_tradition = 0.25    #Prev: global_trade_power = 0.1
    bonus = {
        galley_power = 0.25
    trigger = {
        tag = VEN
    free = yes      #will be added at load.
    venetian_arsenal = {
        naval_forcelimit_modifier = 0.25
        ship_durability = 0.05    #Prev: galley_cost = -0.20
    printing_industry = {
        diplomats = 1
    stato_da_mar = {
        trade_efficiency = 0.2    #Prev: trade_efficiency = 0.10
    state_inquisition = {
        global_spy_defence = 0.3
        yearly_corruption = -0.05    #New
    conscription = {
        global_sailors_modifier = 0.33    #Prev: naval_maintenance_modifier = -0.2, sailor_maintenance_modifer = -0.05
    defend_the_law = {
        global_unrest = -2    #Prev: stability_cost_modifier = -0.1, justify_trade_conflict_cost = -0.1
    provveditori_ai_beni_inculti = {
        development_cost = -0.1    #Prev: land_attrition = -0.10, naval_attrition = -0.10

Owners of Rule Britannia will also have access to more Naval Doctrines for more countries. These are the new ones added to the game we have so far:

  • For Danish countries

  • For Norwegian countries
  • For Dutch / Flemish countries
It is unclear right now if we’ll add more naval doctrines or not, but we have an open ear for more naval doctrine suggestions.

And that’s it for this week! Next week’s DD will be about the most overpowered perfectly balanced country in Scandinavia.

Until then I wish you all a nice week!

Very excited about the changes. Would you consider giving Scandinavia a unique national idea set? The formable still feels a bit lackluster. If not an entirely new set, then it could at least use the inherited ideas of a country which formed it, but have stronger bonuses. For example, if formed by Sweden, Produktplakatet idea would be buffed to +15% goods produced, up from Swedish 10%.

Glad to have Danish flavor and REWORKED IDEAS, thankfully. However, I once again ask if Lithuania will be included in the DLC, as you've mentioned here you're leaving the Baltics, that seems disappointing and misleading for a Scandinavia + Baltics DLC. But, then again, I really like the addition of the Danish rework and looking forward to Sweden's dev diary next week!

NEW NAVAL DOCTRINES!!!!!! seems like that one suggestion was really heard, nice!

also, how much do prestige and dip.rep get weighted for sweden when choosing to remain a pu partner/become free?

edit: does this mean personal unions cost diplomatic relations now???

Regarding ideas for naval doctrines, maybe a naval doctrine (aimed for the Dutch) that deals with increased trade power projection? The Dutch were known to have a competitive advantage due faster and more efficient cargo holding vessels. For Venice and Genoa and other Italian republics a doctrine that has slaves rowing, which could translate into cheaper costs for galleys and higher naval limit. This could give them an extra bite in the Mediterranean. Could also be available to Muslim countries as well.

Maybe a naval doctrine for Ming that is a throwback to Zhang He's expeditions, something about colonial range and trade projection as well.

Edit: image regarding Dutch doctrine loaded later, but I guess that is what was missing in the game.

I was sure Paradox bias would mean Sweden would be saved for last.
But of course, you save the REAL great power that is Norway for last.

Not that I’m complaining. I’ve always enjoyed Norway since I didn’t bust my backside looking for Norge folk songs for nothing.

Any changes to the 'The Scandinavian Constitution' event? It was a trap event for beginners, but now it seems like it was melted into the whole Kalmar union mechanics, am I correct?
  • 2Like
Awesome - I like that there are so many events!! Also for the missons there are over 40, with the brancing ones even more. But most important there are 11 ways to get into the missions. Most of the times it was 3-4, so if one mission didn't work the whole branch was over for a long time.

As you cowork the hansa: Please don't forget all the small OPMs without any flavor/missions in the east/north sea HRE. Maybe there would be room for at least a shared missiontree? (while hamburg should get some extra love) and the Hansa cities some extra events regarding the north...
As of naval doctrins - would be nice to have one for the east sea countries
Dutch Trade fleets looks very promissing, so we can finally join the colonisers not that late

Anyway - good to see finally some new additions for naval doctrins to feel more unique - while you add to existing features, please consider adding imperial incidents about the stuff you added. The Emperor would clearly have an interest regarding a war against the whole hansa, also an incident after the age of reformation if the skandinavian countries hold any land (not just holstein) in the HRE, (maybe also after an united skandinavia, as this was a big threat for the hre and emperor) and an incident if the teutons (want to) join the HRE
As a player Emperor I would at least like to get informed, why the hansa is fighting the north

All in all - great direction. Lots of missions! (even if I don't know many players that use a lot of the coloniser missions - but the rest really are looking so promissing! Way more divers as most of the african ones) also that the brancing missions will start later in the game, so not everything in the first 50 years. nice

New ideas for Denmark and Venice are a nice surprise, I also like seeing more naval doctrines.

I remember reading a while ago that you (as in, the devs, can't remember exactly who wrote it) weren't happy with how the Burgundian inheritance went down and you would maybe work on it for the next major update. Is there any news about that ?

Cool as hell.
Btw if you are reworking/tweaking idea groups might be a good make a dedicated mercenary idea group or alternatively move the merc bonuses around to more fitting places.

Looks really good. Love that more naval doctrines are being added to the game. Does the religious branch take into account that player might opt to convert to Orthodox via Zealots if they opt to complete their trade branching missions first? Also the Kalmar Union government looks cool, really hope the elective monarchies get a relook in the future as they haven't been given much love in the past.

the prose in a couple of these is a little awkward. are the event texts final? the content is fine, no worries about that, it just needs a bit of tweaking

for instance, lets look at the "stockholm bloodbath" text. "did not go without its problems" is not technically incorrect, but its somewhat odd. "did not go smoothly/as smoothly as one might hope" is what youd expect to see here. further down weve got "the arch-king intervened and hold a banquet" which is in the wrong tense, and should be "held a banquet". the confusion probably stems from the next line being in the present tense - the whole event should be in the past tense, even if you mean to imply it literally just happened a second ago, since its honestly just easier to avoid mixups when you pick a tense and stick to it. even outside of the temporal tense of the sentence, though, its again a little awkward - "many of the independence wanting nobles have been captured and executed shortly after for heresy" should probably be more something like "many of our nobles who desired independence were captured and shortly thereafter executed for heresy"

the final paragraph also has problems of a similar nature, but i think you get the point by now. again, the content is fine, it just needs an editor to give it another pass and tighten up the prose a bit

Looks really interesting. I was expecting more flarvor referecing the danelaw but the unqiue PU/Klamar Union mechanics seems interesting to work with. Also, hopefully new danish NIs means there is finally a nation that can somewhat rival british naval supremacy.

Also two additional questions:
1. Seeming the scandinavia decision, will forming scandinavia finally give some new NIs/missions or is it still a purely cosmetic formable and will it continue to require tech 20?
2. Any chance for new NIs for Lübeck since you already reworked venice? Most of it are useless fillers.

My pitch for naval doctrine of Korea:
Pyeongjeoseon (Meaning Flat-bottomed ship; if this seems a bit common, then Panokseon)
With vast tidal plains on Korea's shores, a flat keel will enable a ship to sit comfortably on the tideland and have greater mobility in the shallow waters. Also, it will provide us with more room for the cannons on the board. However, it'll make our ship extremely vulnerable on the high seas.
Fleet fire on the shallow coast: +2
Colonial range -25%
Attrition on the high seas +50%
Movement speed on the high seas: -25%
