Greece spent two million pounds sterling on military spending without a dime in the war, and Bulgaria suffered a direct loss of Dobroga territory, which continued to recoup its investment from the Wallachians.

Therefore, Greece hopes that the three countries can establish a broader alliance, replacing the previous trilateral agreement, which only guarantees to help Bulgaria get West Wallachian territory in the future, so that Bulgaria can agree to give up Dobroga, so that Greece can get out of the war, and Wallachia can establish an independent state. But Greece didn't get anything, so then there were people in parliament who put forward bills that Greece had paid the obligations of the alliance, but not the powers of the alliance, and that Bulgaria and Wallachia should have the same obligations to Greece, but how to make them guarantee it, and there was a proposal to create a Balkan alliance. At the very least, there should be a clause that Bulgaria and Wallachia have an inescapable obligation to assist Greece in the event of aggression by its neighbours.

However, the opposition argues that if Bulgaria and Wallachia ask Greece to make the same assurances, it does not mean that Greece will continue to bear obligations and risks for the other two countries.

Also in the Bulgarian parliament, the reproaches against the government grew stronger, believing that they had lost their actual territory, only to be guaranteed only by Greece and Wallachia. How to ensure that the two countries will fulfill their obligations, they think that it is difficult to restrain each other, and even the alliance may not be able to reassure them, because the agreement itself is a commitment, and if the agreement is not binding, the alliance treaty is also not binding.

In the Bulgarian parliament, there were first calls for the establishment of a Balkan empire, and they hoped that the three countries could establish a Balkan empire under a unified constitution and with a unified royal power as a bond. Together, the three kingdoms formed the Imperial Parliament, which was equal in status and formed an imperial army, commanded by the monarch and supervised by the Imperial Parliament. Only when the military forces of the three countries are under unified command can Bulgaria's interests be guaranteed, and can the military forces of the three countries be ensured to help Bulgaria recover its territory.

The proposal of the Bulgarians, their own parliament was difficult to pass, but this proposal appeared, and then it began to circulate, discussed, became an option.

At this time, the Wallachians were more active than the Bulgarians. Among the three countries, Greece is less of a threat from foreign enemies, the Ottoman Empire, although it still has a residual power, but in fact it no longer poses a threat, Austria-Hungary is the biggest threat to Greece, and occupies the Greek Ionian Islands, which Greece has always hoped to reclaim. After this war, Bulgaria also had a conflict with Austria, which occupied West Wallachia and Bulgaria could not be recaptured by its own forces. Wallachia is threatened and has more territory to be recovered.

The Wallachians had to retake Transylvania from Austria-Hungary and Moldova from the Russian Empire, making Wallachia even more in need of a strong government protection. Coupled with the fact that they had just become independent, and the chaos of various affairs, the royal family showed a high sense of responsibility during the refugee crisis, and had the support of the people at large, or the government and parliament of Wallachia were simply supported by the Greek king, and at this time they were more willing to let the Greek king strengthen his power.

In Greece, Zhou's success was most deeply rooted, so Greece was also willing to support its own king to become emperor. In the eyes of the Greeks, this was also a situation of revival of the Eastern Roman Empire, which could touch the deepest imperial plot in their hearts. Previously, it was Bulgaria that was more repulsive to Zhou Chenggong, but Bulgaria now needed an empire to support them in recovering their territory.

Basically, in the face of a common enemy, and they are all big empires, the three countries have the need to jointly build a state. The problem depends on how to operate, and Zhou Chenggong happens to be a person who is good at manipulating politics.

So under his behind-the-scenes push, the three countries really began to negotiate about the joint establishment of an empire, and the parliament also believed that uniting and building a unified empire would better ensure its own security, at least better than any country alone.

It's just that it is impossible to easily agree on a plan for building an empire. First of all, Greece is the most powerful and populous country among the three countries, with a population of up to 5 million, Bulgaria and Wallachia are both more than 2 million, and Greece accounts for almost half of the total population of the three countries. So Greece wanted to be able to send parliamentarians to the empire in proportion to its population, so that Greece almost controlled the imperial parliament. Bulgaria and Wallachia, on the other hand, insisted that the three countries should be equal in status, with equal power to send representatives to parliament, as in the case of Austria-Hungary, which was equal to the rest of the empire.

The other is in terms of component sharing, the formation of a unified empire, which means that there will be an imperial government, the imperial parliament, and other necessary institutions, which require huge funds to maintain, everyone wants to occupy more power, pay less obligations, so in terms of cost sharing, Wallachia and Bulgaria instead want to share according to the proportion of population, or according to the financial revenue, both of these methods of burden, Greece has to bear half or even more.

There is also the question of the relationship between the imperial government and the governments, if the imperial government is a strong government that can completely control the governments, the three countries will not agree, so the imperial government can only be an institution that makes the three countries feel that it is beneficial and infringes on the power of the three countries as little as possible.

Let the three parties continue to quarrel like this, and it will not be possible to reach an agreement for a century. In the end, it was the emperor who intervened, and he put forward several principles, the first is the principle of reciprocity of power and duty, the second is the principle of the unity of military institutions and customs agencies, and the third is the principle that the constitution of the empire must take precedence over the domestic laws of each country, threatening all parties, if it is not based on these principles of fairness, the empire will not obtain a solid foundation, such an empire, he will not lead, will not serve as the emperor of this empire.

The idea of an empire without an emperor cannot be established, and this emperor can only be Zhou Chenggong, because he is the only monarch common to the three kingdoms, and the three kingdoms are basically recognized.

As a result, all three parties had to accept the emperor's principles, which did make sense and were relatively fair in terms of general principles. After accepting these principles, they found that many of the disputes no longer existed.

The question of the representation of the Imperial Parliament, which is a matter of power, must be equal to the obligation to pay, so it is enough to send deputies directly in proportion to the expenses of the Reich, and the two problems become one problem. Without this principle of reciprocity of powers and obligations, it is impossible for them to reach an agreement.

Under this principle, the three countries quickly reached an agreement. Greece will have 500 seats, 200 of which Greece will have, and Bulgaria and Wallachia will each have 150 seats, thus guaranteeing Greece the most, but less than half, seats. Similarly, the three countries provided imperial funds in a ratio of 4 to 3 to 3. In the future, as the development of different countries increases, the economy and population increase or decline, the seats can be changed, but no one country shall have more than half of the seats, so as to ensure that the other two parties together can balance the first country.

The composition of military strength will also be in accordance with this ratio, not only the proportion of military spending, but also the proportion of the number of soldiers provided will also be according to the proportion of 433. But the right to mobilize the whole people is retained, and in this era of conscription, it is unrealistic to strictly follow proportions, rather than general mobilization. However, the three countries all kept an eye on it, and the standing army was under the jurisdiction of the imperial government, but the reserve army under the conscription system was managed by the governments of the country in peacetime.

On the issue of tariffs, the establishment of a customs union between the three countries, with the example of the German Customs Union, is not controversial. However, the emperor insisted that the customs should be managed by the empire, and the customs duties would go directly into the imperial government accounts to offset the financial expenses due from the three countries, and the deficiencies would be made up and the excess would be refunded. The three countries hope that the funds will be allocated to the governments of the countries first, and the funds due from the governments will be paid by the countries in a unified manner. To put it bluntly, it is still a question of fiscal autonomy. The Emperor insisted that if the countries were unwilling to cede even partial tax powers, such as tariffs, and had such distrust of the imperial government, the empire would not last long, and there was no need to form it. At the emperor's insistence, the three kingdoms made concessions and handed over important financial powers, the power of customs duties, to the imperial government.

Once there is a concession, there will be a second, a third. Tariffs can be transferred, and then there will be postal, transportation, education, and so on.

There is also an important power, diplomatic power, which is also under the unified management of the Imperial Government, which will represent the three countries and speak as a community in the international community.

The powers reserved by governments include full domestic power, the power to form local militias, and so on.

In fact, although the power of this empire was not centralized by a single nation-state, it was more centralized than the historical German Empire, and it was stronger than the current Austro-Hungarian Empire.

At the break time when Zhou successfully promoted the establishment of the Balkan Empire, Russia and Austria-Hungary were not idle.

Both sides amassed heavy forces, but large-scale wars, especially all-out wars, did not break out in the end.

Determined that they had no advantage and that there was a risk of total defeat in all directions, and that in terms of foreign aid, Britain could basically only provide financial support and was not very active, and Prussia, under pressure from France, categorically rejected the decision to enter the war. Bismarck knew very well that he did not want to get involved in this kind of great power struggle at all, and his only purpose was to unify Germany.
