Hungary is already an interesting country, as it has a lot of room for expansion, and even some historical struggles, that defined the nation's diplomacy in the years of the war. The main focus of this mod is adding more flavor to the country, primarily with the new focus tree. The political branch allows for either a revisionist policy (which focuses on restoring old territory), or an ideological shift, which enables a democratic, or communist Hungary, each with its own decisions to make. Following the revisionist branch presents opportunities to reform Austria-Hungary, demand former territories of the realm, and even develop the newly acquired lands.

Latest changes

For detailed version history, check the file descriptions.

v 4.2.0

  • Some tank variants have new icons.
  • Sobrance is now part of a supply zone, and the Czechoslovakia strategic region.
  • The flag of the Kádár administration (with the Kádár crest) is now properly loaded, once the focus is completed.
  • Artillery icons should now no longer show up as generic black outlines.
  • Descriptions and icons of some planes and tanks have been updated.
  • Italy is now notified, if Hungary honors/dishonors the terms of the Adriatic Initaitive.
  • A whole new branch of focuses have been added, which handle the various orders of battle, and armament plans of Hungary/Austria-Hungary. The Árpád-Line focuses have also been moved under this branch, and have been extended somewhat. - courtesy of warchief1978
  • The communist branch has been expanded, enabling, amongst other things, the formation of the Warsaw Pact, by spreading communism in Poland, and inviting them into the Comintern.
  • The liberal branch has been expanded, and it now has access to some king-election focuses that were exclusive to the conservative branch before.
  • The king-election branch has been detached from the conservative branch, and has received some new options.
    • The branch is now available after completing either the "Liberal Ideas", "Hungarist Ideas" or "Maintain Conservative Government" focuses.
    • The ideology chosen will limit which candidates can be chosen as king.
    • The focus "Dismantle The Monarchy" has been slightly reworked: The focus will turn Hungary into a republic, and is only available to non-aligned, or democratic ideologies.
  • Hungary now starts with the national spirit "A Kingdom Without a King", which gives a slight reduction to national unity. The national spirit can be removed in various ways (eg. electing a king, or officially dismantling the monarchy)
  • New focus on the aviation branch: "The Aeronautics Institute": grants a research bonus for aircraft models, and some air experience.
  • The leader of democratic Hungary (Endre Bajcsy-Zsilinszky) now has the traits "Anti communist" and "Anti fascist".
  • Some missing trigger tooltip localisations were fixed in the Hungarian version.
  • For purposes of unambiguity, the focus "Restore The Monarchy" was renamed to "Restore the Austro-Hungarian Monarchy" (this is only affects the English version, the Hungarian version was already unambiguous).
  • It is now possible to start the "Demand Slovakia" focus, even if Carpathian Ukraine / Ruthenia is a Czechoslovakian puppet.
  • The national spirit given by the focus "Military Land Survey" now impacts max planning instead of planning speed. - New focus on the Revisionist branch: "Budapest Research Group". The focus creates a research group for the New Central Powers faction.
  • The Austro-Hungarian focus branch has been expanded with two focuses, that lead to a monarchist coup in Germany, restoring the German Empire. (focus pictures courtesy of the Wolferos team)

Known Issues

Piece of advice:
The mod is under continuous development, and I don't have the capacity to thoroughly test every single feature. Bug reports are therefore much appreciated, as they help me in finding all the flaws that were left in during development. Also, if you are playing with the mod enabled, consider making frequent saves, to prevent bugs from potentially ruining your campaign.

  • Some people experience issues with the focus tree, mostly reporting that the focuses are "tangled up", making the whole tree a mess. I have not been able to replicate the issue yet, but as soon as I find out what might cause it, I'll get on to fixing it.
  • Some people have reported, that the event warning them about the British decree against Hungarian expansion is not showing up (this is supposed to happen if you keep aggressively grabbing territory through national focuses). I have not managed to replicate the issue yet, so any feedback is appreciated.
  • Some people have reported, that the referendum for Burgenland does not work. I have (yet again) been unable to replicate the issue. Any input is welcome.

If you detect an issue, that has not yet been reported, consider disabling any other mods, reinstalling the game, then reinstalling the mod, and starting a new game before reporting it. Many problems are solved by starting with a clean slate. If you really want to make sure that the issue is with the mod, and not your installation, also delete everything non-essential from the User folder (Documents/Users/[Username]/Paradox Interactive/Hearts of Iron IV/). Save games and mods can stay, the rest will be regenerated when you start the game again.


As of v4.0.0, the mod is compatible with v1.4.0 (Oak) of the base game
The detailed compatibility description has been migrated to the readme file, to conserve space on this page.

I hope the next version takes advantage of the new German Tree coming in the next update. That'll be awesome! Redo WW1

Just saw in the latest stream that the new german focus: integrate the war-economies under align hungary and align romania will turn those nations into puppets and give them 4 MIC if they are in the axis.

Also those align foci give +0.20 towards their ideology. Guess there should be a buff against anti fascist ideology (increasing ban the arrow cross party fascist reduction daily) Or just mod the german focus tree so it no longer does that and prevent them from taking a focus that puppets you when in axis.

Any idea if you can extend the Arpád line to Banat aswell due to it leaving a gap since one can fortify southern transylvania (personally I'd like it the province got split in 2 mostly because the province is too long and it might prevent less bordergore.) I assume you updated the extend the arpád line focus to also affect the new Székelyföld province?

If you ever got time It would be nice to have some news reel events for taking territory through foci, etc. Maybe one for the renewed Polish-Hungarian border if you own land bordering poland (giving increased relationship or something else.)

The German focus tree is already modified by the mod. I'll think of something to prevent them from necessarily puppeting Hungary.

Yes, the Árpád-line will be extended to the new state. I doubt I will stretch it all the way into Bánát though. The Árpád-line was a defensive position in Carpathian Ruthenia. I saw it fitting to be able to extend it along the Carpathian mountain range, but Bánát is where that ends. It does not have the defensive advantages of the rest of the line, so it wouldn't make sense to stretch the line there. (If Bánát is included, why would the line stop there? Why not continue along the southern border?). You can always build forts manually where you see the need for it.

Találtam egy bugot, amiben a játék összeesik Csehszlovákia vége fókusz után, hogyha Szlovákia és Ruténia magyar bábállamok.

Just read the update google drive for future updates.

Will the Béla kun focus be mutually exclusive with the kádár and Rákosi administations? Also since Béla kun historically died in 1937 will this option be timed (aka cannot do if soviets finished great purge and its the year 1938 and beyond?)

Is it also a possibility to allow Bulgaria to join in with the proposed partition of Romania between Hungary and the USSR (having the treaty of craiova fire then and having Germany create WT would feel odd if the USSR and hungary are partitioning Romania in the first place.)

Will the south-transylvania state also get split up like the north-transylvanian state?

Also just an idea but not sure if feasible: making states that already have a medium-high amount of Hungarian population integrate faster. Such as Pancevo (+-17% hungarian) Northern and Southern Partium aswell. (perhaps through the new decisions or something to make them integrate instantly for a cost or something else. As I would see those states integrate faster then states that didnt have much of Hungarian population)

Due to technical issues I can only play your mod in april again.

Yes, the new communist branch will be mutually exclusive with the other two.

I don't plan on including Bulgaria in the partition at this time.

South Transylvania is not split up. Why do you think it should be? I guess the eastern part was where most of the German (Saxon) population lived, but I don't plan on making them releasable as well.

You bring up a fair point with the integration speed. States with significant Hungarian population should integrate faster. I'll add that to my TODO list.

May I ask how you have access to the google drive file you referenced? The google drive folder is meant to be accessible to the developers of the mod only.

Reply Good karma+1 vote

You once posted the link to the drive, and then I bookmarked it. But seems you now fixed it as I can't see it anymore.

Találtam egy bugot: Ha puppeteled Rumániát azelőtt, hogy elvégeznéd a "Reassert Old Claims" fókuszt, akkor Rimánia csatlakozhat a Kisantanthoz annak ellenére, hogy egy puppetnak kéne lennie.

Yes, I plan on continuing to develop the mod. Currently, I'm waiting for the next DLC, so I can use the new features coming with it.

I'm afraid I won't be making new 3D models, since I haven't got any experience in 3D art, and the DoD DLC already adds new unit models for Hungary.
If you'd like to listen to some Hungarian music along with the mod, there is an addon to do just that, under the addons tab of this site (
