Description and Background

Prior to the end WW1 the states under Au-Hu declared independence which consisted of Bosnia, Croatia and Slovenia. It failed to get recognition and formed with Serbia which later become known as Yugoslavia (South Slavs)

In an exercise of alternate history. The state survives and continues to 1936. It faces a political conundrum. It must choose between the west, the axis, communists and even allying with Serbia. The choice is up to you. The SHS has claims in the balkans and Istria. How will this affect what path the state goes down? Will it survive?


-Yugoslavia focus tree modified for SHS - Original Mod Here
-Releasable nations
-Bosnia - Tag: BOS
-Slovenia - Tag: SLA
-NDH (Croatia) - Tag: CRO
-Skopje/Macedonia - Tag: SKJ
-All ideologies/flags/politicians included with realistic politicians as leaders.

Leaders and Backstories

Ivan Šubašić
Party: Party of Rights (Stranka Prava)


Ivan Šubašić is for a pro-SHS state with less autonomy and more centralised government in Zagreb. However the state has come to a cross roads of where the SHS will lead and what path it will take. He has not ruled out forming Yugoslavia with more autonomy inside the SHS than what was suggested 18 years prior after the end of the great war.

Srđan Budisavljević
Party: Democratic Party (Demokratska Stranka)


Srđan Budisavljević is a Croatian Serb liberal. In the SHS he wants more autonomy for the people inside their ethnic regions along with equal religious rights. Dismantlement of the SHS is a long term goal to make sure the state ends peacefully.

Josip Broz Tito
Party: League of Communists (Savez Komunista)


Josip Broz Tito is a Croatian communist and to an extent indulged in Yugoslavism. However uniting all south slavs is not his priority due to the already unified state of the SHS with South Slav populations of Croats, Serbs, Bosnians and Slovenes being unified.

Ante Pavelić
Party: Ustaše


Ante Pavelić is a Croatian fascist that saw the SHS as a Catholic authoritarian state. Serbians were considered not compatible to him. His plan was to kill 1/3, expel 1/3 and convert 1/3. The Bosnian Muslims were to be reeducated about their roots and to be converted back to Catholicism.

Minor Goals

-Add ministers to Bosnia and Slovenia ✔
-Create Slovenia, Bosnia and Croatia Focus tree (looking unlikely, having issues) ✔ (Croatia Only)
-Potentially expand the SHS focus tree (Next patch should see this)
-Maybe add more states inside SHS such as Herzegovina, Slavonia, Current day Croatia region. ✔
-Add Greater Serbia tree (Unlikely)

What do you mean? It is updated to 1.4.2 or do you mean new content?
Jared4Wally Sep 16 @ 6:20pm 
any news of the 1.4.2

Really appreciated, I try to put as much accuracy historically into my mods even if the timeline is changed.

Good work ProKosovich. Your mods are quite well made and well researched. Two thumbs up!

I'm going to say maybe with 56, I think it would work but a slight chance it might break it.
Bigbadnin Sep 7 @ 5:59pm 
Compatible with Road to 56?
ProKosovich  [author] Jul 10 @ 3:14pm 
I finally updated the mod. And I added lots of neat stuff.

It's as simple as putting the tag or something like that into localisation in the "adjectives" line.
ProKosovich  [author] May 6 @ 7:10pm 
Okay, that's something i'll check out. I might know why actually.
PlutonicRabbit May 6 @ 3:58pm 
This could also mess up various events too.
