At the end of the 19th century, as the Austro-Hungarian Empire continued to infiltrate Serbia, people of insight in Serbia believed that if Serbia did not expand into the Aegean region, it would be annexed by Austria-Hungary sooner or later.

Therefore, Serbia adopted a radical expansionist policy, including the propaganda of national separatism everywhere, and a series of chaotic ideas, which also laid the groundwork for the later disintegration of Yugoslavia.

In addition to Macedonia, countries are also infiltrating other regions. The most famous are the "Great Bulgaria Plan" and the "Greater Serbia Plan"; Of course, the "Greater Greece Plan" and the "Negoro Plan of the Gate" are also indispensable.

The Great Bulgaria Project is a Bulgarian nationalist ideology aimed at restoring the largest territory in Bulgarian history.

Of course, the Bulgarians have not been so stupid as to really restore the largest territory in history, and when it is time to give up, they still choose to give up!

The range of targets set includes: the plain between the Danube and the Balkan Mountains, the North and South Dobroga, the Sofia region, Pirot, Vranje, Northern Thrace, parts of Eastern Thrace, Macedonia and other regions.

The main targets were all aimed at the Turks, and they did not stupidly encircle Austria-Hungary, Greece and other countries in one go, and even then it was beyond the scope of Bulgaria's capabilities at that time.

The Great Serbian Project is interesting, it is also Greater Serbianism, the concept of national irredentism put forward by Serbian nationalists.

Well, the basic goal is to unify the areas inhabited by Serbs, and there are also claims for areas where Serbs are minorities.

This region is difficult to define, advocating the creation of a larger Serb state in the western part of the Balkan Peninsula in southeastern Europe.

It was even worse when the radicals grew in power at the end of the 19th century, and this nation encompassed the entire Yugoslav nation.

At the most basic level, the area includes: Serbia, Montenegro (Montenegro), Bosnia and Herzegovina, Albania, Macedonia, Croatia, Slovenia, etc.

If the activists are aiming for it, the small Balkans can no longer accommodate Greater Serbia, Greece, Bulgaria, Romania, Hungary, Austria, and even Moldova. (Not necessarily accurate, from Baidu, for reference only)

Of course, these activists are only a minority of the minority, and they are radicals within radicalism, which can be understood as madness!

And that's not all, there are also Slavic peoples who are influenced by Pan-Slavism and openly advocate the unification of the whole world!

You read that right, after the establishment of Yugoslavia after World War I, there were people who advocated the unification of the Slavic peoples of the world and the establishment of a Great Slavic Empire with the Serbs as the core! Even the great strategic idea of the unification of the USSR came out!

Well, just take it as a joke! What country doesn't have a few madmen? Serbia in those days, there were no more madmen!

Blind nationalism, devoid of economic and military strength and international support, can only lead to disastrous consequences. Great Serbianism eventually became the trigger for the outbreak of World War I!

The Greeks are still self-aware, perhaps it was the first "Greco-Turkish War" that woke up the Greek nationalists, the Great Greece Project was just a dream, shouted twice, and after feeling tired, they stopped shouting!

The Negro plan of the gate, the establishment of Yugoslavia was once realized, but he belonged to the unified, so it was also completed, right? Maybe I didn't think the result was so good, and then I became independent!

However, all this has changed radically in this time and space, under Ferdinand's butterfly effect!

Of course, these plans still existed, but the "Greater Serbia Plan" died as soon as it was shouted.

The situation in the Balkans before 1892 was basically the same as that of parallel time and space, with little change, at most the Bulgarian government had built a little more church schools outside the country, and the scope was a little wider.

Since the establishment of the Royal-Russian Alliance, history has turned a corner here! First Ferdinand provoked an arms race in the Balkans, followed by the economic crisis that was destructive, a little bigger!

Then, beginning in 1893, the Greek and Serbian governments were forced to stop their expansion in Macedonia for financial reasons. After the Bulgarian War, Serbia directly closed down most Serbian schools and churches!

The time entered 1895, and Serbia, which was originally ambitious, was now licking its wounds and did not have the energy to come out and make trouble.

Now the most active is Negoro (Montenegro), which is working hard to establish the Kingdom of Montenegro!

George I of Greece was still hiding in the shadows, looking for an opportunity to give the Ottoman Empire a smack, similar to Ferdinand's thoughts.

The two sides tacitly agreed to export the revolution to the Ottoman Empire, although Ferdinand lit a fire, if the Greek government did not cooperate, the Greeks in Turkey would definitely not be so fierce.

The Macedonians relied on the Serbs until 1860 and then on the Bulgarians. The main factor contributing to this was the impetus of the Russian Empire.

The Russians religiously and diplomatically led the Macedonians closer to Bulgaria, and the attitude of the Russian Empire had a huge impact on all the Orthodox people of the Balkans!

After the alliance between Russia and Bulgaria, this effect became even more obvious, and the Orthodox faith zone in the Balkans is moving closer to Bulgaria. Taking advantage of this, Ferdinand's government accelerated its penetration into the Balkans.

Romania is the hardest part, watching the Balkan countries expand, Carol I has no ambitions, and there is nowhere to show them, so he can only watch the excitement with peace of mind on the sidelines!

Hungary and Serbia to the west, Ukraine and Moldova to the west, Bulgaria to the south, and the Black Sea to the east.

During the Bulgarian War, the Romanians were ready to come out for a piece of the pie, but unfortunately due to their relationship with Austria-Hungary, they chose to support Serbia.

But Serbia lost so quickly that the war ended before Romania had time for a national mobilization, and there was no way who would call his northern neighbor the Russian Empire? And the Russian Empire is precisely an ally of Bulgaria, and the Romanians do not dare to bet anyway!

More than 70 percent of the country's main forces were deployed on the front line of Moldova and Ukraine, and Carol I was no matter how confident he was in his ability to use troops, he did not think that Romania could defeat Bulgaria with a partial division.

Coupled with the unstable situation in Romania at that time, and the possibility of a new peasant uprising at any time, Carol I finally chose to abandon the Serbs.

…… (As for the Ottoman domestic situation, let's make up the brain!) There are only four words: wolf smoke everywhere! ）
