Balkan crisis
The Balkan region is situated in Europe, close to the Aegean Sea and the Black Sea.
It was a part of the Ottoman Empire.
In 1912, Balkan League (Greece, Bulgaria, Serbia and Montenegro) defeated Turkey. However, the conflict among the allied nations in sharing the benefits of war led to the break-up of the League and resulted in wars among them.
When Austria laid its claim over the Balkan region with the support of Germany, Serbia claimed this region with the support of Russia.
During this time, a Serbian youth Gaverilo Prinsep, assassinated Francis Ferdinand, the heir to the throne of Austria at the Bosnian capital Sarajevo in July 1914.
Austria held Serbia responsible for it and declared war on Serbia on 28 July 1914.
The allied nations rushed to help their allies. Almost all the nations of the world directly or indirectly were involved in it. Therefore this war is known as the First World War.
A peace conference was convened at Paris in 1919 to discuss post-war situation, under the leadership of the winning allies, Britain and France.
They signed different treaties with the defeated nations. Among these treaties, the Versailles Treaty signed with Germany in 1919 was the most important one.

The allies occupied the rich mines of Germany. Above all war guilt was imposed on Germany and was disarmed
