Europa Universalis IV - Development Diary 28th of June 2022

Dzień dobry! Welcome to today’s developer diary! We will be taking a first look at the new Polish, Lithuanian and Commonwealth trees!

But first, allow me to introduce myself. I am Big Boss, the newest addition to the Content Design team. I started playing Europa Universalis during 2011 and have loved spending time looking at and painting maps since then. More recently, I have been working on several mods, so some of you may know me from my work there. I am genuinely very excited to share with you all the hard work the team has been putting into this update and praise the immense amounts of support I have received from my new colleagues and mentors! As we delve into this developer diary, please keep in mind that the icons and event images as well as numbers displayed are by no means final!

The beginning of the game finds Poland rudderless, with her King, who maintained a union over Lithuania, Hungary and Croatia, having died a mere day earlier, after risking his fate against the Ottomans at the battlefield of Varna. Thus, Poland starts at a quite precarious state: a vacant throne, the Nobility’s Golden Liberty in full effect, and surrounded by powerful neighbors. At the same time, the Ottomans in the South and the Muscovites in the East are taking great steps to consolidate and expand their domain.

So what’s new for Poland? For starters, they have access to two new T1 Government reforms. The first one is the Great Sejm reform, granted to them at game start:

2.png

Bear in mind that any and all numbers you see in this Developer Diary are strictly work-in-progress and are subject to change, especially in response to valuable feedback from the community!

The second T1 reform is a special reform for Poland upon accepting the Union with Lithuania:

Unlike the Great Sejm reform, the Polish Elective Monarchy grants the ability to elect various princes to the throne, a steeper absolutism malus and, similarly to the Great Sejm, it enables the Parliament and grants a reduced Unrest bonus.

Speaking of the union with Lithuania, it should be noted that some changes were made to that event. Now, it will fire even if Lithuania is a player. A Player Lithuania will be able to decline, but AI Lithuania will always accept. This was done in order to further facilitate the idea that Poland and Lithuania make a great co-op campaign, which is also complimented by both mission trees granting bonuses that follow the spirit of cooperation between the two nations. Here’s how the new event plays out:

3.png

4.png
To further immerse the players into the gravity of their choices, I went ahead and added a few dynamic missions for Poland, based on your choice between the local noble or the Lithuanian PU. Accepting the Lithuanian union will lead you towards developing the Lithuanian core as well as elevating their nation financially and (later on) artistically as you prepare them for the eventual integration:

5.png

6.png
This branch ends with you declaring the Imperial Commonwealth, which grants a powerful temporary bonus:

7.png

On the other side, declining the PU with Lithuania will grant you the path that leads you towards the West via entering the Empire, leading it and passing reforms.

8.png

Note: You will still receive claims on Lithuania and be able to form the Commonwealth!
The first mission’s reward is an event for the current Emperor to admit you in the Empire:
31.png
This path will also contain new and innovative rewards such as the new modifier ‘Reasons to Elect’:

0.png

The final mission for the Imperial path of the West will imbue Poland with a sizeable bonus to their Imperial Authority Gain as well as extra Diplomatic skills for her ruler.

Main Body of the Polish Tree​

Addressing the aftermath of the Varna crusade will have a profound impact on the rest of the missions further below. Opting to pursue friendship with Hungary and/or Bohemia will lead both parties to a shared sphere of prosperity, historical friendship and powerful bonuses to last as long as the alliance is maintained. However, should you choose to rival and become antagonistic towards them, the reward will switch to a PU CB / Permanent Claims based on the country’s union eligibility. To be clear; you can pursue friendship with one of them and antagonize the other, the choice rests entirely with you!

2Yf_ckUJUFNu5aCHKpYrLOTQczg4pZzdcIS-4tR7vAYoe3dei43MniG3iVD83F9PKO6G-QlzgVIP9iFqq46ahbZJzb8vDx39qBWs4NN1bTJxoQRVQEhoEIHAL477R9zEdo6Qm7VEpX1GFcYvJGQ

Internally, Poland needs to address the growing influence of the nobility. Regarding that, in the mission ‘Leverage the Magnates’, you are granted the opportunity to cooperate with them and win their favor via great concessions or directly oppose them. Keep in mind that due to their tremendous influence, opposing them is quite difficult. Working alongside them will reduce the cost of Parliamentary Bribes (which will be increased by default for 1.34) and grants a small Loyalty bonus until you pass further legislation as the Commonwealth to reduce their authority. Alternatively, if you dare to oppose their authority, you will gain an event to face a major uprising of Magnates that will also reward you with a unique new modifier:

image (42).png
The missions directly below it follow the turbulent history of Poland and will have you attempt to pass legislation and reform the government by undoing nobility influence. Choosing to oppose the nobles in the mission shown above will also impact the following few missions!

The mission ‘Great Sejm’ will unlock a new personality type ‘Reformist’ which grants more reform progress growth as well as new unique Parliamentary Issues for Poland! The new personality can be assigned to all rulers with at least 4 Administrative Skill.

Resolving the matter of Hungary and Bohemia will yield dynamic rewards based on whether you completed them via conquest or diplomacy. This also impacts the reward for ‘Balance the Princely Lands’:

14.png

Moving on, you will also be tasked with harnessing the Polish Renaissance, dealing with the Piasts of Mazovia and developing Krakow:

image (31).png

image (32).png

On the Conquest front, you will be led towards quelling Roman’s Rebellion in the South and seizing control of Wallachia, raising troops from nobility strongholds and assisting the Prussian Confederation:

15.png

17.png

18.png

Note: Assisting the Danzig merchants may lead to the formation of Royal Prussia as a subject under the Polish crown which will have its own few missions to break free from your hold!

Of course, the Polish tree holds many many more cool new additions, events and rewards and they are up to you to discover!

Finally, Poland (and the Commonwealth in general) will have access to a new special unit, the Winged Hussars! I am very excited to finally talk about this new unit.
  • They will be available for Poland and PLC via a national idea
  • In our current build you may recruit 1 Winged Hussar per 100 Development
  • They come armed with +1 Cavalry Shock and +100% Reinforcement Cost
  • They are further empowered by your choices in the mission tree!

image (33).png

The Winged Hussars have arrived!

As a side note, we currently have not chosen yet what colour the Carolean and Hussar unitbox will have. Janissaries are red, Cossacks are orange. Feel free to suggest potential colours!

The Lithuanian Mission Tree​

Alongside Poland, Lithuania will be getting her very own missions. It builds upon the old mission tree and greatly expands it, honing and improving upon the unique aspects of playing as Lithuania:

19.png

Among the highlights of the Lithuanian tree are the ability to call upon a host of Cossacks, new unique T1 Government reforms (yes, plural!) and the potential to utilize the Tribes Estate for a limited time.

21.png

22.png

23.png
Alongside these new additions, Lithuania will gain access to new events and flavor:

24.png
If you choose to remain as Lithuania for a little longer beyond Administrative Tech 10, we made sure to accommodate your stay with flavorful missions that will entice you to stick around a while in order to get all the rewards and complete the tree:

25.png

The Commonwealth​

Building upon the solid foundation that is the Polish mission tree, Commonwealth missions originally appear as part of the Polish tree, marked as “Locked Missions”. Unlike other formables, we took the creative decision to showcase the Commonwealth tree to the Polish player, before accessing it. The reason behind this is to prepare the player for whatever challenges and requirements the PLC missions will ask for and ensure the player is not caught off guard.

Thus, if you hover your mouse over the Locked Missions, you will see the requirements as well as potential rewards beforehand.

Now that’s out of the way, let’s take a look at some of the missions we have in store for the Commonwealth, starting with this one, my favorite, ‘A Lifetime of War’

10.png

26.png
Note; Since the mission only requires one of the listed requirements for it to be completed, you may see fewer choices in your version of the event, based on which way you choose to complete the mission. Shape and sharpen your army the way you want to!

Note: Please be aware that these numbers are not final!

A PLC tree would not be complete without its ‘Invest in Eastern Poland’ Mission, which requires you to have 40 provinces with a manufactory or a level 3 Center of Trade and either 40% Global Trade Goods Produced or 7 ‘Trading-in’ Bonuses. Here is the reward:

image (34).png

Following in the steps made before forming the PLC, and after completing the Great Sejm mission, you will gain access to flavor missions that will assist you in passing and repealing the Articles of Agreement (Pacta Conventa) and even rewriting them completely from scratch, with more favorable terms on the behest of the monarch, if you chose to oppose the Magnates in a previous mission:

27.png

The conclusion of the major flavor part of the tree is the mission ‘Dominate the Markets’ which grants a new mechanic we made specifically for the PLC, the ability to reset or extend a Golden Era:

image (38).png

image (35).png

External Affairs of the Commonwealth​

No major mission tree would be complete without a robust conquest path. That much is true for the PLC, which will be granted missions, a new Casus Belli and even gain Streltsy as a one-time reward from one of their missions:

image (36).png

image (37).png

29.png
Moving on, ‘Prevent the Deluge’ will task you with dealing with whoever the ruler of Scandinavia is, be it Sweden or anyone else. You may deal with them in a multitude of ways, including diplomacy or conquest. Should you choose to approach Sweden diplomatically, both nations will be positively impacted by a wave of prosperity. Sweden will gain +25% increased production for its metals and historical friendship while you will gain direct access to Scandinavian copper and iron, reducing your overall military costs:

28.png

The final conquest mission for the Commonwealth will set you up to become a supreme great power, requiring you to be a hegemon and have a tremendous amount of development under your belt:

30.png

Note: Development Efficiency’s number will be green in the final build!

The philosophy of the PLC missions is that of a tree whose content should last the average player till around the 1700s at the very least, so expect a lot of hard work and very worthwhile rewards from every single mission in this tree!

While we are on the subject of the Commonwealth, I would like to showcase some new implementations that the team worked hard for. As I mentioned above, the PLC will now enjoy a lot of new content including 2 different sets of National Ideas. One for nations whose primary culture is Lithuanian and one whose primary culture is not Lithuanian (namely Poland as an example):

Polish PLC Ideaset:

Code:
PLC_ideas = {
    start = {
        nobles_loyalty_modifier = 0.1
        num_accepted_cultures = 2
    }
 
    bonus = {
        monthly_reform_progress_modifier = 0.25
    }
 
    trigger = {
        tag = PLC
        NOT = { primary_culture = lithuanian }
    }
    free = yes
 
    plc_prosperous_folwarks = {
        global_trade_goods_size_modifier = 0.10
    }
    pol_jagiellonian_university = {
        idea_cost = -0.10
    }
    plc_the_obrona_potoczna = {
        drill_gain_modifier = 0.25
        army_tradition = 1
    }
    pol_winged_hussars = {
        cavalry_power = 0.3
        can_recruit_hussars = yes
    }
    plc_refine_our_golden_liberty = {
        monarch_admin_power = 1
    }
    pol_royal_guards = {
        infantry_power = 0.10
    }
    plc_tempered_by_neighbors = {
        discipline = 0.05
    }
}


Lithuanian PLC Ideaset:

Code:
PLC_LIT_ideas = {
    start = {
        global_manpower_modifier = 0.25
        tolerance_heretic = 3
    }
 
    bonus = {
        governing_capacity_modifier = 0.15
    }
 
    trigger = {
        tag = PLC
        primary_culture = lithuanian
    }
    free = yes
 
    warlord_dukes = {
        max_hostile_attrition = 1
    }
    plc_tempered_by_neighbors = {
        discipline = 0.05
    }
    new_magdeburg_laws = {
        development_cost = -0.1
        global_trade_goods_size_modifier = 0.05
    }
    reciprocal_guarantee_of_two_nations = {
        all_estate_loyalty_equilibrium = 0.05
        diplomatic_annexation_cost = -0.15
    }
    lithuanian_hussars = {
        cavalry_power = 0.2
        can_recruit_hussars = yes
    }
    statutes_of_lithuania = {
        global_unrest = -2
    }
    lithuanian_renaissance = {
        technology_cost = -0.05
    }
}

Special thanks to Verinity Void whose National Ideas work was partially adopted for the Polish PLC ideaset!

I am at your disposal for any questions you may have about the trees, as I’d love to read and answer your feedback, and also feel free to suggest tweaks as well. Thank you for taking the time to read my very first Developer Diary! Next week my colleague @Ogele will come back, to talk about some sea-related new content.

As for the color of winged hussars, it should be Crimson
RGB 220 20 60
Bez tytułu.png

The raspberry color, i.e. crimson or amaranth, was considered a more noble shade of red and therefore it became the favored color of the former Polish nobility, who liked to wear crimson.

Good that the mission tree became much better than it used to be. It is definitely a good work and a good first mission tree (or a few). A great improvement too, and the idea changes are nice.

Sad that there are no changes to Lithuania apparently. No vassals... No historical events with Cossacks or Ruthenia either if I got it right, that's disappointing. If I remember right, Cossack estate rarely rebels so there is no tension simulating historical one either.

The concept of developing Ruthenia was also heavily flawed - it historically coincided with the Polish Counter-Reformation and oppression of Orthodox population that contributed to the Cossacks Uprisings.

The Lithuanian relationships with Ruthenia are flawed too - because the relationship of Lithuania was vassalic with Ruthenian lords in Kyiv, Chernihiv, Severian principalities and etc. It was the result of the major civil war 10 years before the game start, and one of compromises made after it was the autonomy and respect to Orthodox lords. It would be revoked only later in XV century, and attempt to revoke it from some lords would spark Lithuania-Muscovy wars. One if such lord families that switched allegiance from Lithuania to Muscovy, Glinskie, gave the princess to Russian Tsars and was a mother to Ivan the Terrible.

It's a terrible shame EU IV still cuts off historical content in Ruthenia like this. It's not detrimental to game of course. Just disappointing.

If I'm not wrong Lithuanians should have buff while fighting in forest using them to destroy superior teutonic heavy cavalery with there light cavalery there and also I believe Lithuania at least in erly times have way better generals than Poland had they were also more focused on having profecional militery that could challange teutonic, moscavic, horde, livonians, and polish. Lets not forget Lithuanians are more focused on cavalery and light cavalery specificly since they had to deal with the horde erly on while also having to deal with teutonic order. Also it would be way more interesting if Romova religion would exist as event to rise up again and be able to go back to paganism

Hi! I love paradox and this is my first post ever here. It was worth it to me to make an account for this question. I would like to request one fix in EU4 - the spawns for the Centers of Reformation are pretty ahistorical and numerous, as we have three centers for protestant, three for reformed, one Hussite (potentially), and one for anglican (optional). All the protestant and reformed Centers almost always are ALL in Germany (because the first countries to convert are often proximal to the first Center, and then get a Center themselves). Furthermore if Anglicanism is enabled, that is too many Centers of Reformation leaving almost all of Western Europe to some form of protestantism EVERY single game. Almost every game of mine has been painted blue (like France, italy, Poland, Austria, Germany without a single catholic province, etc). My request is that if Anglicanism is enabled, a Center of protestantism is removed, and that the rest of the centers have a greater chance at spawning somewhere other than proximal to the first center (like perhaps Scotland or Hungary very far from the original centers). OR even the counterreformation has a Catholic Center of Reformation. I love the reformation era and would love for this to be fixed! Sorry this has nothing to do with this dev diary.

Will the winged hussars be renamed Uhlan in a later game?

HELL NO. Polish Hussars and Uhlans have nothing in common. Winged Hussars where HEAVY cavalry based on light Early Hussars from Serbia and Hungary. Uhlans on the other hand is light cavalry based on eastern Crimean/Mongolian cavalry.

Would it be possible to introduce Hussar as a special unit for southern Slavs and Hungary, Poland should also use them so that they later transformed into winged hussars.

Pollish Hussars (husaria) and Hussars (huzarzy) are completely different units, both tracing it's origin in Early Hussars. There was nothing "special" in Early Hussars and Hussars and they should not be made into special unit, but just normal eastern technology light cavalry units.

Nice addition! I hope there is some restriction about integrating Royal Prussia. If Poland integrates Royal Prussia immediately, it seems meaningless.

It should not be called Latin Empire but Constantinople's Empire (Imperium Constantinopolitanum) - it is historically accurate name for "Latin Empire" and term used by the Catholic West to describe "Eastern Roman Empire"

Oh man, we get to form the Latin Empire!

So, quick question: when you conquer Constantinople and give it to either the Byzantines or a Latin Empire, do they become independent (presumably as a historical friend), a PU, or a vassal?

I'm giddy, because, while I'm going to do a Novgorod->Russia game now that we can stay a Republic, and, of course, I'm going to just have to conquer Constantinople, its just not an ideal location for the capital of an Empire in that region. But as the Commonwealth, I can set up a friendly state of some sort there, and secure my southwestern frontier! Its perfect!

Lithuania will have events to represent the rebellions of the Cossacks and you will even have the ability to play as the Separatist Cossacks! We can't reveal everything in the Dev Diary. To add some more; Lithuanian missions will allude and refer to reducing internal autonomy ^_^

I think that "Byzantine Empire" and "Latin Empire" could be the same tag but called Byzantium when orthodox and Constantinople when Catholic.
