Well, I hereby extend this TL for Austria-Hungary and I go into more detail:
Austria-Hungary has no clear
war aims regarding Serbia. In general, the Austrian leaders are in favor of annexation, while the Hungarian leaders want to leave a smaller Serbia independent. An independent Serbia is seen as a danger by Austria, because it can continue to propagate the Greater Serbian idea and serve as a base for terrorism. The danger of annexation is that the Slavic influence in the Habsburg monarchy will be strengthened, which will weaken the Hungarian influence. No agreement was ever reached in OTL.
In this TL, Austria cedes Galicia to the new Habsburg kingdom of Poland. As compensation, and in order to remain credible as a great power, Austria succeeds in realizing the annexation of Serbia and Montenegro. These countries are being ruled as condominiums for the time being, pending a final solution. The
Austro-Hungarian occupation of Serbia was very repressive, but because lasting peace is only possible with an equal relationship, Austria is making a concession to the Serbs and Montenegrins. Following the example of Bosnia, a constitution is drawn up for both countries in 1917:
Serbia and Montenegro are each given a diet with legislative powers for internal affairs. Foreign policy and defense, however, remains in the hands of the joint Austro-Hungarian ministers. Serbia and Montenegro have no influence on this. The budget must also be approved by the Austro-Hungarian finance minister.
In the years that follow, the economic situation for the Serbs and Montenegrins gradually improve and tensions ease. However, in Bosnia, Serbia, Montenegro, as well as in Croatia-Slavonia and to a lesser extent Slovenia, a movement is emerging that strives for the establishment of a South Slavic kingdom with an equal position with respect to Austria and Hungary. In the respective diets, this movement achieved a large majority. Emperor Karl I supports this idea of
Trialism and various proposals are being developed.
However, these proposals are repeatedly rejected by the Hungarian government and parliament. The Austrian government does approve the proposals and is increasingly frustrated with Hungary's refusal to implement reforms. Tensions are also increasing again in the South Slavic countries. These eventually lead to riots and attacks against Hungarian police and government institutions. The uprising also spread into Serbian inhabited areas in Hungary itself, i.e., in the Vojvodina and the Banat. Hungary wants to use the army, which is refused by Austria. A deep constitutional crisis is emerging. Hungary stands alone and must eventually back down and agree to the most far-reaching proposal:
- The Kingdom of South Slavia is founded with Karl I as king. This kingdom consists of five Crown lands, each with a large degree of autonomy. Brod is designated as the capital; a small town halfway the Zagreb-Belgrade railway line and with a direct railway line to Sarajevo. Brod will not be part of a Crown land, but will form a neutral capital district. Freedom of religion is established in the constitution.
- Hungary must not only cede Croatia-Slavonia, but also the southern Banat. It must also accept a border change with Austria, whereby the German-speaking west is ceded to Austria (Burgenland). Ujvidek (Novi Sad) will be retained for Hungary.
- For the Slovenes, a long-standing wish is coming true, i.e., to be united in one Crown land. Slovenia becomes part of South Slavia to strengthen the Catholic influence against the Serbian Orthodox.
- As in the Dual Monarchy, this Triple Monarchy has three joint ministers; Foreign Affairs, Defense and Finance. From now on, each state will provide one joint minister.
How plausible is this TL? How will the Triple Monarchy (What is actually a good name for this state?) develop further? What are the Czechs, Slovaks and Romanians going to do?
