Before the First World War, the five traditional European powers were: Britain, France, Germany, Russia, and the Austro -Hungarian Empire. (This ranking is regardless of the one, you can write first, which one first)
At that time, Serbia, which is located in Balkans, has a close relationship with Tsarist Russia, but was regarded as nail in the eyes of the Austro -Hungarian Empire. Worried.
In 1879, Germany recaptured their war in Puchi because France was concerned that the situation would develop in a certain stage (the Pander War was the war that the Kingdom of Prussias broke out in order to unify Germany and the second largest country in France. Prussia won the victory and ended up the German Empire. The start time of the Polish war was from 719, 1870-May 10, 1871). Outside of the friendly federal, Germany and the Austro -Hungarian Empire formed an alliance. Three years later, Italy also joined, and the Three Kingdoms Alliance was formed. In this alliance system, if Italy is attacked by France, Germany and the Austro -Hungarian Empire will give support; Italy said that he will maintain neutrality when Russia attacks the Aunu Empire.
On the other hand, France and Russia were alliance in 1894, while Britain and France signed the British and French Treaty in 1904.
Because Russia’s attitude towards the German Emperor William II was quite annoyed on the Balkans’ issue, it was quite annoyed to end long -term disputes with the British issue with Britain on the issue of Britain, and then associated with it.
In 1907, the Three Kingdoms Association between Britain and France and Russia reached a contract.

Germany realized that it was about to face the test of two combat, so it was necessary to grab the attack before the number of French -Russian troops was far better than its own.
In the past few years before the war, from the general to the people, everyone felt that the war should be unavoidable;
On June 28, 1914, in the Austro -Hungarian Empire, he did not get the Sarajevo Wo of the Persianian capital recognized by the Sarania, which was recognized by the Persian people who lived in the Persia, and the heirs of the Austro -Hungarian imperial throne, which was officially visited. The Serbian nationalist led by Nuo Pollingus was assassinated. The assassination was called the assassination of the Sarajewo.
The occurrence of the assassination of the Sarajen nest clearly shows that Serbia’s secret organization has provided a geographical advantage for the assassination team. The Eunu Empire immediately regarded this as evidence of Serbia and himself.
At first, the assassination of the Sarajewo was just a regional struggle between the Austro -Hungarian Empire and Serbia, but no one expected that this assassination was the fuse of this war. Start the prelude. The crisis spread rapidly. In less than 4 weeks, all European powers were involved in it, and the First World War broke out.
