Victoria 3 - Dev Diary #48 - Unification

16_9.jpg

Hello and welcome to yet another Dev Diary for Victoria 3! Today’s topic will be Unification, aka the process of turning one nation into another, ‘greater’ nation, such as the historical example of the Kingdom of Prussia turning into the German Empire in 1871.

When talking about Unification, there’s two distinct types of Unifications - regular Unifications and Major Unifications, the latter of which have some special mechanics associated with them. We’ll go over the former first.

The Unifications you’re able to form range from small one-region nations like Baluchistan to vast ones like India.

A Regular Unification is, plain and simple, a particular country that can be formed by other countries. These may be countries that have existed in the past (such as Poland), came into being after 1836 (such as Italy), are alt-history countries that we have deemed plausible or interesting enough to include (such as Arabia) or may even be countries that already exist on the map in 1836 but can be re-formed if they were to break up or be conquered (such as the United Provinces of Central America).

In order for one country to become another, there’s a few conditions that must be met:
  • The forming country must share at least one Primary Culture with the Unification country. For example, any country with either South German or North German Primary Culture can form Germany, which has both.
  • The forming country must have a lower country tier than the Unification country. Country tier is an inherent ‘status’ assigned to each country based on how it was historically perceived, and gives Prestige based on how high the tier is. For example, a country that was historically regarded as a Kingdom gets a bit more Prestige than one that was a mere County. This is a fairly weak effect, as the idea that some countries/titles are simply more inherently prestigious than others was falling out of fashion in the game’s era, but serves as a useful way to determine which countries would realistically strive to change their identities, as it’s quite unlikely that Poland would want to turn itself into just Galicia-Volhynia, while Krakow might jump at that opportunity. There is one exception to this rule - a country may form a Major Unification of the same tier, if they are themselves not already a country that counts as a Major Unification. For example, the Empire of Austria can become the Empire of Germany despite not increasing their tier in the process.
  • The forming country must own or be the suzerain of the owner of a sufficient number of the integral State Regions of the Unification Country. Usually, what a Unification country considers to be its integral State Regions maps directly to the Cultural Homelands of its Primary Cultures - so the integral State Regions of Italy is any State Region that is considered to be the Cultural Homeland of either North Italian or South Italian culture.
  • Certain Unifications may require you to research technologies such as Nationalism or Pan-Nationalism to be available.

Once these conditions are achieved, unification is as simple as the press of a button. Once that button is pressed, the forming country will immediately turn into the Unification country, annexing any subjects of theirs that share a primary culture with the Unification country and own land in its integral State Regions in the process. For this reason, it isn’t necessarily required (or even desirable) to outright conquer other countries that are standing in the way of your unification dreams - subjugating them lets you count their land towards the required goal, and allows you to integrate them into your unified country with less Infamy than you would otherwise get.

With seven of the nine integral Australian State Regions under their control, New South Wales are ready to proclaim themselves as the united Dominion of Australia

That’s about all there is to know about regular Unifications. So then, how do Major Unifications differ? Quite a bit, actually! Major Unifications are countries such as Germany and Italy, which historically had strong nationalist movements agitating for their creation from the disparate polities they were divided into. At the start of the game, these differ little from regular Unifications, but once any country sharing a primary culture with the Unification Country researches the Nationalism Society tech, new mechanics called Unification Candidates and Unification Diplomatic Plays come into effect.

Unification Candidates are, quite simply, countries that aspire to unify the aforementioned disparate polities under a single flag, the clear historical example here being the Kingdom of Prussia’s ambition to unify Germany. In order for a country to be a Unification Candidate, the country must be at least a Major Power. However, if there are other (potential or current) Unification Candidates that are Great Powers, then Major Powers are not considered to be valid Unification Candidates as they are simply seen as too weak by comparison.

There can be up to 3 Unification Candidates at any given time, and if there are more potential candidates than this, then the 3 with the highest Prestige are chosen. It is also possible for there to simply be no Unification Candidates at all if no potential formant is at least a Major Power. As power rankings change, so do the candidates - any candidate which falls below the rank threshold ceases being a candidate, and any potential candidate that achieves it becomes a candidate (assuming there is a free slot or they can beat out an existing candidate in raw prestige).

Prussia and Austria each have a handful of supporters for their bid to unify Germany, but most of the minor German countries remain uncommitted.

So then, now that I’ve told you all about how to become a Unification Candidate, what do you do once you actually are one? Well, most importantly, you can now begin to receive the support of non-candidate countries sharing a primary culture with the Unification Country - aka, any country which has the potential to be a candidate but doesn’t make the cut. These countries can instead choose to throw their weight behind one of the existing Candidates, effectively telling the world that they would like to become part of something greater than themselves.

For the purposes of holding the necessary number of integral State Regions, any Unification Candidate gets to hold the land held by countries supporting them, so if both the Mecklenburgian Duchies back Prussia’s candidacy, this means that Prussia gets to count Mecklenburg towards the number of North/South German State Regions they need.

Furthermore, Unification Candidates get access to two special Diplomatic Plays, which can be launched from the Nation Formation panel. These are called ‘National Leadership’ and ‘Unification’, and are modelled largely on the historical process by which Germany came into being.

National Leadership is only relevant if there are multiple Unification Candidates, and is effectively one candidate challenging another for supremacy, as happened in the Austro-Prussian War of 1866. This play always targets another Unification Candidate with both sides having as a primary wargoal to force the other to renounce their candidacy. Supporters come into play here, as any country pledged to support one candidate or the other will automatically back them in the play, and fight on their side should things escalate into war.

Having amassed a large number of supporters, Prussia is poised to challenge Austria for German Leadership and become the sole Unification Candidate remaining
prussialeadershipplay.png

When a Leadership wargoal is enforced, the defeated party will become permanently disqualified as a Unification Candidate, which also lowers the maximum number of candidates for that Unification Country by 1 (to ensure that there is not simply an endless number of new candidates rising up to challenge the dominant candidate). In other words, if Prussia defeats Austria as happened historically, then Austria will no longer be a Unification candidate, and unless another German country such as Bavaria has been able to rise to Great Power status, Prussia will be left as the sole candidate standing.

It’s important to note that Austria being disqualified from candidacy for Germany, does not actually prevent them from ever forming Germany, but it does mean they can no longer use the tools available to candidates and so would have to rely on brute force to achieve that end.

When there is only one Candidate (either because there was only one to begin with, or all others have been defeated), the Unification play can be used. This is a special play that involves every non-Great Power country that shares a primary culture with the Unification Country and owns land in its integral State Regions. As before, any of these countries that support the candidate will automatically be on their side in the play, while all others (regardless of who they might have supported or not supported in the past) will be on the opposing side, with the strongest among them as war leader. Just as with any other Diplomatic Play (including National Leadership) any country with an interest in the region where it’s taking place may butt in.

In a Unification Play, the attacker is angling for no less than the full annexation of all other (non Great Power) countries on the potential target list, including their own supporters (who may end up fighting to be annexed). As such, it may seem like there is little reason for a player country who isn’t a Unification candidate themselves to support a candidate, but (assuming your goal isn't annexation of your own country) there is one valid reason to do so: To play for time. Supporting a unification candidate is very likely to make them friendlier towards you, which means that if you’re playing as Anhalt, surrounded on all sides by Prussia, it can be a valid strategy to throw your support behind them to avoid an ‘intervention’ in your country, and abandon that support once you’ve secured some strong allies.

With Austria now out of the contest, German unification seems within Prussia’s grasp… if they can find a way to avoid or overcome French and Russian intervention

That’s all for today! Join us next week as we turn to the topic of Characters with another dev diary by our lead content designer and AAR aficionado, neondt.

Will countries keep their state religion when forming a new country, or is that fixed for each unification? For example, will Germany be protestant when formed by Prussia and catholic when formed by Austria, or will it always be protestant?

Can countries lose a primary culture if one of their current primary cultures is not a primary culture of the unification country?

Also, are there other major unifications in addition to Germany and Italy and if yes, can we get a list of them?

Are there other potential major unifications, or is it just limited to Germany and Italy?
I think Canada was one as well? Since they are a bunch of small Canadian colonies and you can't exactly become their overlord or conquer them without breaking free from Britain.

My understanding from the Canada AAR (which may be outdated given that its rather old) is that Canada (and maybe australia as well?) unifies by the would-be unifier getting events to annex the other countries within the formable. Would make sense too, given how in the dev diary, australia is formed via countrolling the states, and I doubt war between the colonies is how that happened.

I see that nations can be reformed after being dissolved. Would England be able to unify the United Kingdom/British Empire?

It seems like the Franco-Prussian war isn't modelled here.

I think that last screenshot shows something that is roughly like the Franco-Prussian war getting ready to happen. Prussia is trying to annex all of these North German minors with the backing of South German states and France and Russia could potentially intervene to stop it. So if Russia is kept out but France decides to step in to oppose the Unification Play then that would basically be the Franco-Prussian war.

So there is no possibility of nationalist liberal revolutionaries to win in some german countries and force unification?

No "Crown from the gutter" event?

Can player refuse being annexed after he supports another country in unification play?

Many of more traditionalist conservatives were strongly against the idea of unfied nation-state. For example prussian Ludwig von Gerlach https://en.wikipedia.org/wiki/Ernst_Ludwig_von_Gerlach. Is it somehow reflected in the game? For example characters could have views on the unification issue just like they have on other policies.

When you enter a diplomatic play, can you get the bigger powers on your side? For example, promising Baden to France?

Maybe if you beat the French and take Alsace-Lorraine before you make the play, they won't be able to take part in it? Do truces prevent participation in plays?

Assuming that the AI takes into account balance of power. A unification play by Germany may result in France siding against Germany assuming they are strong enough and France also has Germany as a region of interest. I never understood why Alsace Lorraine was ever required to form Germany to begin with, even Bismark didn't want it and only reluctantly agreed. It then remained as an "imperial province" directly administered from Berlin for the rest of the century. Realiatically, the war happened because France feared a strong Prussian state and so this Unification diplomatic play is a great way for the Franco-Prussian war to be modeled in a far less contrived way; Germany is no less German without some French province.

I think it is fine the way it is presented here. Taking Alsace-Lorraine in a war would bring you closer to your goal of having enough provinces. In an alternate timeline it is definetely possible to see another kind of unification, be it rather diplomatically like the 48/49 attempt in the form of the national assembly, an escalated version of the 1866 brothers war where Prussia could have pressed on to capture all of the German lands or lastly the historical 1871 unifcation by united force which is somewhat represented by the Unification play. Im usually quite concerned about these things but I actually appreciate it here that they open another route for us, a route which is plausible. This also opens up another historical chance which could see Austria uniting Germany.


Unrelated to my quote there are questions I have:
1. How do you intend to handle a revolutionary unification? Having 48/49 in mind, is there an option to found a nation like Germany or Italy in the aftermath of a collapse of the old regimes, out of the ashes, with a vastly different set of politics?
2. The role of Switzerland. While Switzerland was not really a player in the historical picture for the unification, it is still a South German homeland and should therefore count towards the threshold to unify Germany. Switzerland should strictly oppose any unification attempt by a major power which does not conform to the Swiss principles however. If you are able to sway the other major countries like Bavaria in an alt history route without pulling them into a defensive war then the position of Switzerland should be reevaluated within such a new system. Also, without proper involvement of them, be it via a common market, puppet or strong relation between the Unifier candidate and Switzerland, they should be excluded from the unification play.
3. How are non homelands handled during a unification play. Altough this might not always have to be a consideration, depending on the nature of the unifcationit in form of war or a rather diplomatic solution I wonder how this will be handled. For example could Prussias parts that contain Polish lands try to secceed or what about Hungary, Slovakia etc. in the case of Austria.
4. I didnt see Luxemburg on the list. How will it be handled during the German unification?

Loving the depth of Major Unifications! I'm curious — how many Major Unifications are planned? Obviously Germany and Italy, but what other formables do you think will be included in this feature?

What's the decision making process there?

What would happen with the Unification Play if there are no viable targets to oppose? Say Prussia had every German Minor as a supporter and nobody was on the fence/against it?

I'm pretty sure any power with a strategic interest in the region can enter the unification diplomatic play to either support or oppose the candidate. That way France can support Sardinia-Piedmont and oppose Prussia.

I will say the thing I find weird is the idea that Prussia would have to go to war with these North German minors in order to annex them and unify Germany if say France intervened on their behalf. Historically Prussia formed the North German Confederation at Bismarck's behest as an intermediary step to full German unification after the Austro-Prussian War. That step was in Vicky 2 but appears to be absent from Vicky 3 because of the introduction of these unification mechanics. Wouldn't it make sense for formable countries that have multiple primary cultures to allow a Unification Candidate that has won a National Leadership play to unify those states that share its primary culture before going for full unification? Or is that something we're seeing happen in the final screenshot since the targets of the Unification Play are all North German minors and it doesn't include any of the South German states?
