EU4 - Development Diary - 28th of May 2019

Hey folks! Welcome back to another rousing Dev Diary! I'm @Ofaloaf, and following the pattern of previous diaries, I'm going to talk a bit about some Italian missions trees we've been working on before switching gears and letting @neondt discuss some other very exciting features we’re adding to the Italian experience.

One of the biggest factors in designing missions for the Italian states was Italy itself. Unified Italy will have its own mission tree in the expansion, and the unification decision that creates Italy also changes the mission tree over to that new Italian tree. This gave certain limits to the scope of missions for Italian states- If we encouraged the player to conquer too much too quickly, they'd be able to form Italy early and miss out on half the missions scripted for them as an Italian minor, and I certainly don't want anyone to miss out on a single speck of beautiful content I make.

Because of that, the missions for Italian states ended up far more focused and smaller-scale than some of their counterparts elsewhere. Take Florence, for example:


Florence was still technically a republic and a commune at the start of EU4's timeframe, but it was a republic already strongly dominated by the House of Medici. The Medici reigned in Florence for centuries, playing a role in its transformation from a republic to a duchy and then into the Grand Duchy of Tuscany. Along the way, they also started a short line of Renaissance Popes, and married one scion, Catherine de' Medici, to King Henry II of France, where she played a key part in the French Wars of Religion.

Florentine missions encourage some conquest in Italy, but not terribly much. Most of Florence's missions are about building up the power of the state and totally not preparing the way for the end of the republic and the formal establishment of hereditary rule. Prestige and personal power are the key themes of Florentine missions. That, and accumulating money. An Italy formed from a Florence that has completed all of its Florentine missions should be an obscenely wealthy Italy.

In contrast to Florence's limited goals, Venice probably reaches the furthest in its missions. Venetian missions don't focus too much on Italy, but do encourage it to flex its muscles and assert its power both on terra firma and overseas.


Venice's expansionist missions encourage it to revisit the good old days when a doge could ransack Constantinople and turn a crusader kingdom into the client of a city-state built on a muddy lagoon. There are also some more forward-thinking military missions which urge Venice to consider the problems the Holy Roman Empire might pose, and gently encourage it to crush Austria and hear the lamentations of the Habsburgs. The diplomatic power of the Serene Republic is also flexed as Venice is encouraged to magnify its own majesty and make its ambassadors masters of their craft.

I'm also really proud of the Plague Doctor Training mission, completing that will make some disease-related events much rarer and outright disable others. It's not an immediate payoff, but man wouldn't it be nice for your citizens to get the plague less often?

While Venice may be busy coveting the Eastern Mediterranean, Milan is all about Italy.


Milan under the House of Visconti was one of the major powers in Italy. During the reign of Gian Galeazzo Visconti, from 1395 to 1402, Milan reached its greatest extent, asserting control as far south as Pisa and Siena. However, following Gian Galeazzo's death, Milanese fortunes waned, and his son, Filippo Maria, never produced a male heir. The chaos following Filippo Maria's death in 1447 is what ultimately led to the brief time of the Ambrosian Republic and the rise of the House of Sforza.

Milanese missions reflect this Milanese history of expansion and grandiose rule under the Visconti and Sforza, with missions trying to recreate the heights of Gian Galeazzo's rule and beyond, while also encouraging some internal development of the realm at the same time. An Italy formed by Milan will likely have a stronger-than-average military and a well-developed Lombardy under its control.


I’m @neondt, and as @Ofaloaf said above I’m here to talk about some additional Italian content we’ve been working on lately. I’ll focus on Florence and Milan since they have the spotlight this week, but there’s more to come.

As my colleague said, Florence was a city-state dominated by the Medici family. We’ve long desired a way for Florence to keep its ruling family through republican elections, and now at last it’s here. The new Signoria government reform (and legacy government) enables the dynastic candidates seen in the Political Dynasties reform from day 1. Unlike Political Dynasties, there are no penalties to the ruler skills of dynastic candidates and there is no random candidate bonus. In addition it enables Royal Marriages. Bologna, Lucca and Siena will also begin with this government reform, and it will be available to other Italian republics and Italian custom nations.

Medici rule was violently interrupted by the rise of the radical cleric Savonarola between 1494 and 1498. We’ve converted the existing event chain about Savonarola into a more coherent Disaster and added a few more events. During the “Bonfire of the Vanities” Disaster all of the events related to Savonarola’s rule will contribute to Savonarola’s popularity or unpopularity. Should Savonarola become too unpopular or die, his reign will end and the Medici will be able to return. But if Savonarola gathers significant support from the people, Florence will be put on the path to Theocracy and gain the ire of the Pope.


On the topic of Milan, the big thing we felt was missing was the absence of any mention of Francesco Sforza in the game. To that end we’ve modified the Ambrosian Republic event significantly and added several more events, once more converting it into a Disaster. Certain nations will be offered the opportunity to claim the vacant throne of Milan, putting them at odds with some of Europe’s most powerful nations and potentially sparking the Italian Wars. If during this Disaster Milan finds itself at war or fighting rebels (a likely situation), the renowned condottiero Sforza will become available as a General. Milan can refuse him, but turning down one of the greatest military commanders of his time will have consequences - he can either join your enemies (always Venice if Milan is fighting them) or else become a Pretender rebel.

Eventually Sforza will discover that his enemies within the Republic have double-crossed him. Historically this caused Sforza to turn against the Republic and seek the throne for himself, but the player will have an additional option. Granting Sforza absolute military rule over the Republic will change the government into a Military Dictatorship, a new tier 1 reform and legacy government. Military Dictatorships elevate their rulers from the ranks of their Generals and there is no election cycle, similar to the Pirate Kings of Golden Century. Monarch skills are derived from the candidate’s skills as a General. Of course Sforza can be denied this power, at which point he will become a Pretender rebel. Even allowing Sforza to rule as a tyrant will not appease him forever. Soon after he will declare himself Duke, and the player can decide whether to accept his bid for the throne, restore the Ambrosian Republic, or appoint a new Captain-General. The AI will typically choose to continue granting Sforza power, with Sforza eventually becoming Duke. We felt this would be a better path for the AI as relying on Sforza to triumph as a Pretender is far from a safe bet. The player however can navigate the rise of Sforza however they see fit, pursuing any of the possible outcomes.

That’s all for today! We may return to talking about Italian content in the future, and we certainly have more to show. As always there’s plenty of time before release, so let us know in the comments which Italian mission trees and historical events you’d like to see in the future. Next week however we’ll be moving on to our map reworks of both the French region and the Balkans, so expect a meaty dev diary.

Why Siena and Lucca have the Signoria government? They were actual Republics, in which the was sort of balance between the powerful families. A Signoria was attempted in Siena by the Petrucci family but then failed.

So my questions are three:
• Which are the “powerful families” that rule in Siena and Lucca at the start?
• There are new mechanics to make you switch between a Republic and a Signoria (like the Republican Dictatorship) or we just have to switch manually as if the rule of a certain family was unopposed?
• Are there new events (or mechanics) unique to the Signoria government type?

On a sidenote, I hope that the Papal States, Savoy and Naples all get a unique mission tree.
I love the new flavor added here! Hopefully the Pope, Naples, Savoy and Genoa receive some similar mission tree attention in due time.

Will there be any further map changes to Italy? While changes are appreciated, I and many others on the last diary found it to be rather lackluster in comparison to the scale of the German map changes, especially when it came to Central Italy.
Extremely glad to see a more focused, smaller scale mission tree - something I wish was true of other mission trees!

Does the new signoria government enable actual dynasties i.e. will it show up on the dynastic map and have a consort and heirs?
Some nice flavour additions here, as well as detailed, organised mission trees; just what I love to see. Can't wait for the Balkans and the Return of the French Minors next week!
nice to see some inept missions and more "disasters" let's hope they are designed in a way that they actually fire in more than 30% of the games, unlike the times of trouble or nomadic frontier that never fire with out player interaction

There is an interesting alternative approach to Italy here that could be explored.

Italy and Germany as they exist now in EU4 are made to represent the nationalistic 19th century versions of these states.

But there is also the medieval kingdoms of Italy and Germany (alongside Burgundy-Arles) which existed as substates within the HRE.

It would be nice to be able to resurrect one or the other in the form of reviving the medieval kingdom. Indeed, this would be one avenue for HRE emperors intent on centralizing state power to do so. They could be kingdom-rank tags rather than empire-rank, and have special dispensation to remain within the HRE and wield considerable (possibly electoral) influence.

Since we are in the midst of reviving other medieval things such Lotharingia, Swabia, etc. Why not do it for nations as fundamental as Italy and Germany as well?

Personally, I think it makes more sense to have a tag that reaches into the past to revive these states than trying to recreate a future nation whose form is not yet determined.

Also, another question:
Why is the lower Absolutism cap for a Signoria at the same level as an Oligarchic Republic and less than the Ambrosian Republic, Free City, Tradiing City and Noble Republic?
If the Signoria stands for a Republic bent by a powerful family that rule over it (the missing step between a Republic and a Monarchy), why not reducing the Absolutism cap penalty? At least they should match the Noble Republic. The Ambrosian Republic was weak but might have higher Absolutism than a Signoria, why?
Unified Italy will have its own mission tree in the expansion
Awesome to hear that Italy will finally have its own mission tree. Will other formable nations such as Germany be able to receive this treatment? Also, I do hope that the largest kingdom in Italy, Naples, will be able to get some unique missions.

That's already changed in the current build. Screenshot is a bit old.
Will updated Genoa missions get content about Black Sea colonies and Dniester trade?

I could use more trade colony-based content in general. The amount of trade hubs both Genoa and Venice had sprinkled around the Mediterranean is surprising, and most of it is absent. Maybe we'll see more changes in that regard?
Not to be picky, but you should decide whether you want to use the name Terraferma (Venetian missions) or Terra Firma (Milanese missions).
