In this situation, Hungary began to demand mobilization to resist Russian aggression.

One was to prevent the Russians from cooperating with the separatist forces in Transylvania, and the other was to use military force to combat and suppress the separatist forces.

The central government of the empire, too, wanted to combat Russian aggression on the one hand, and on the other hand intended to use military force to suppress the rebellion in Wallachia.

In this case, they issued a general mobilization, conscripting troops from the imperial territories of Bohemia, Dalmatia, Austria, as well as the Kingdom of Hungary.

Hungary mobilized, the tsaress saw the complication of things, she also had a headache, she lacked the experience to deal with the situation, in fact the monarchs of Europe were not ready, they did not know that all the troubles they encountered after that would evolve from the struggle for power at the top in the past to the struggle for national power, and all future wars would begin to be triggered by national contradictions, or could not be controlled by nationalism. This is no longer their previous dynastic war, or the war of succession.

What to do now for the female tsar, the local Moldovan political forces, ethnic groups, did not refuse Russian rule, but they made a request to the Russian army, they wanted the Russian army to help them recover Transylvania, and they began to negotiate with Wallachia to merge into one country. Moreover, the head of the local nobility and politics of Moldova, Lisandru Joan Kuza, had basically agreed with the Wallachian political forces.

They can accept a unified Orthodox state under the Tsar's banner, they can recognize the Tsar's royal power, but hope that an autonomous government can be established, there is a precedent, Russia rules Finland, almost just let Finland be autonomous, Finland has its own parliament, laws and conquests, they don't resist, and the Tsar doesn't have much desire for control over them.

But the situation in Finland, similar to the relationship between North Korea and China, is that the direct annexation of North Korea does not strengthen China, and it is not harmful for China to leave it to fend for itself, because it is a relatively isolated, peripheral region. The reason why the tsar strengthened his control over Poland again and again was because Poland was located in the core and the requirements for Poland were different.

The intention of the Tsar to Moldova was to gain access to the Danube valley through it, and thus to exert her influence on Central Europe, especially on the Slavs of South-Eastern Europe. This inevitably required Moldova to be closer to Russia, rather than Finland, which ruled only to protect the security of Petersburg.

At the same time, the female tsar had an agreement with Greece, and Wallachia had been divided to Greece, so that the Greek king would hand over the Bulgarian-controlled Dobroga to the Urals, which was a complicated partition agreement, but it was suddenly complicated by the entry of national forces in Moldova and other places.

Austria-Hungary also mobilized for war, and the female tsar immediately responded-for-tat, announcing the mobilization of the Russian Ukrainian regions, and if there was to be a big war, Western Ukraine would also be taken back. For this reason, it can form an alliance with France and let France help contain Prussia so that Prussia will not take the opportunity to intervene.

At this time, the Greeks suddenly moved into action, and their army marched into the Dobroga region on a large scale, and the combined Greek and Bulgarian forces, totaling 500,000 men, were deployed in the lower Danube, in the name of guarding against possible regional chaos.

Greece did not declare war on either Russia or Austria-Hungary, and Zhou Chenggong's patience and spiciness, which were not at all on the same level as his nephew Zhou Chun.

On the one hand, he had an agreement with Russia, but on the other hand, he urgently contacted Britain and France, hoping that the two countries could mediate the war. The attitude of Greece and the United Kingdom of Bulgaria is that they do not want to see chaos in their eastern part.

Britain expressed support for Greece's attitude and communicated with the King of the United Kingdom. King Zhou Chenggong said that he did not want to see war break out in Wallachia and would never support the territory here being given to Russia. Britain has expressed support for this, and they do not support territorial changes in the region.

The reign of the female tsar made Russia's role as a Chinese thug more and more real, and Britain could no longer accept Russian expansion. Prussia was also concerned about the Balkans, and they basically had the same attitude as the British, not supporting the territorial changes here, that is, supporting the continuation of the Austrian emperor's rule here.

But the locals had already revolted, and the Wallachian army was armed, and they expelled the Austro-Hungarian officials and declared independence.

Although the tsaress did not want to accept the advice of Kuza of Moldova, she still sent troops into Wallachia, this is the best time, it is certainly better to annex Wallachia than only one Moldova, as for the question of Dobroga, she believes that her husband can understand, for the time being, there is no chance, there is always a chance that it is not.

The operation of the Russian army in Wallachia is quite smooth, because the local forces in Wallachia see the Russian army as a liberator under the guidance of the Moldovan political forces.

The Austro-Hungarian army began to suppress Wallachia's independence from the upper reaches, and the rebels could not defeat the Austro-Hungarian regular army, so they had to retreat step by step along the Danube, and soon lost one town after another, and in less than a month, even the capital Bucharest.

The war inevitably led to a large number of refugees, and the United Kingdom of Greece and Bulgaria opened its borders, established hundreds of refugee settlements on the west and south banks of the Danube, and secured a sum of aid from Britain to purchase food for distribution to the refugees. King Zhou Chenggong also continued to visit various refugee settlements, emphasizing the need to provide the best possible resettlement for the refugees and ensure their food and medical care.

Tens of thousands of refugees continue to flee to the west bank of the Danube, the rural peasants on the other side of the Danube, they fear that the civil war will plunge them into war, most of the peasants do not care about the future of the country, they only fear for their own safety, so they cross the Danube near their doorstep, and they hear that the Bulgarians on the other side of the river will help.

In fact, there is not much help they need, because most of the farmers bring their own food, the distance to flee is not far, and the local agricultural areas are abundant, most of them have surplus food, all they need is a safe shelter. It is the city dwellers who really need large-scale relief. Among them are citizens of cities on the tributaries of the Danube, such as Bucharest, and port areas such as Galati. Among them, the residents of the Bucharest region mainly escaped from the suppression of the rebels by the imperial army, while the residents of the Galati region escaped under the attack of the Russian army.

Not only have these refugees been resettled, although the conditions of resettlement may not be comparable to their original lives, but there is a sense of psychological security. In addition, they saw the kings of the Greeks and Bulgarians who had come to comfort them in person, and the other party admitted that he was full of sympathy for the poor people. The war was condemned, and they were assured that their safety would be protected.

Due to the king's intensive visits to refugee settlements, he rarely visited ten refugee settlements a day, and in a short period of time, he visited more than 100 refugee settlements, although not all of them met him. Through the mouths of those who came first, those who came later were also full of gratitude and trust in the king.

On the one hand, Zhou Chenggong bought people's hearts and minds, and on the other hand, he carried out political work, and constantly appealed to major powers to mediate in the international community.

Around the Balkan question, the European powers quickly split into two blocs, with France and Russia supporting Russia's military operations and Anglo-Prussia opposing Russia's military operations. France did not care about Russia attacking Austria and expanding its power, while the British and Prussians feared that Austria would be too weak and Russia would expand too much.

The Tsar succeeded in pressuring Kuza to pledge allegiance to Russia, and she appointed Kuza as Prime Minister of Moldova, agreeing with Moldovan political forces.

Moldova, will not be merged with Transylvania and Wallachia in the future, Kuza will be the prime minister, and the female tsar supports Kuza to carry out reforms, agrees to Moldova to establish an independent parliament and government, and formulate a constitution, but the constitution must guarantee the absolute power of the queen.

So in the end, it was almost a personal compromise between Kuza and the queen, who was given the legal powers, and Kuza, through the support of the female tsar, was given the power to carry out reforms.

Soon the Austro-Hungarian Empire had suppressed the uprising in Wallachia, the Hungarians had also suppressed the uprising of the Transylvanians, and the Russian army had advanced into central Wallachia and approached Bucharest.

The Russian army mobilized 800,000 troops, Austria-Hungary also armed 700,000 troops, and more than 1 million troops confronted each other on the Wallachian plain, and a large-scale war was about to break out.

The British and Prussians began to mediate, hoping to persuade Austria-Hungary to abandon Moldova and Russia to accept limited expansion and avoid this large-scale war.

The weak Austro-Hungarian Empire was willing to give up Moldova, and the Tsarina was willing to accept it, but Hungary demanded that Russia pledge to give up its support for Moldova's claim to Transylvania forever.

The Hungarians had put both the Austro-Hungarian and Russian empires in a dilemma, and if Russia publicly pledged to renounce its claims to Transylvania, the loyalty of the Moldovans it had just won would be quickly lost, and if Austria-Hungary did not support the Hungarian claims, the Austro-Hungarian Empire could disintegrate.

The result was that the two sides could not reach an agreement.

The Great War broke out anyway, and the Russian army and the Austro-Hungarian army went to war in Wallachia, and the Russian army was stronger than the loose Austro-Hungarian army, and soon recaptured Bucharest.

The war between the two countries created more refugees, almost all over Wallachia and Transylvania. Hungary's suppression of the Transylvanian rebellion was very cruel, a large number of local Dacians fled to Moldova and Wallachia, and the refugees in Moldova were relatively stable, but the refugees in Wallachia were again drawn into the war and had to flee again.

The population of the Danube basin is large due to the good agricultural conditions. Wallachia and Moldova both have populations of about two million, and Transylvania has a population of about four million, of which about six million are of the same Wallachian ethnicity, three of whom were later affected by the war.

The number of refugees who eventually fled to the Bulgarian side was more than 300,000.

Due to the reception of more than a million refugees from the Ottoman Empire a few years ago, the Greeks have rich experience in receiving and rehousing refugees, the life of these refugees has a basic guarantee, ordinary people in troubled times, the desire for stability, coupled with the conscious performance of the Greek king, he quickly won the favor of the refugee group, even if a large amount of materials used to resettle refugees are actually from the British, but the gratitude has been harvested by him.

The annexation of Wallachia by Russia was unacceptable, not by the two Great Powers of England and Prussia, and not by the Wallachians at this time.

The Wallachian political forces, who had fled from Bucharest to the Bulgarian side, began to establish political organizations here, and it is clear that they must have had the support of the Greek Bulgarian kings, otherwise it would not have been possible to establish political exile organizations on Bulgarian soil.

Then this organization, which was established, was naturally pro-Bulgarian to the king.

There has not yet been an agreement between the great powers, and the king of Greece and Bulgaria has completed the act of buying people's hearts, and the time is ripe for him to act.
