Question

What do you mean by balkan problem. How did it led to first world war

Answer 1

a. The Balkans which was a region comprising of varied ethnic groups which in present day would be Romania, Bulgaria, Albania, Greece, Macedonia, Croatia, Bosnia-Herzegovina, Slovenia, Serbia and Montenegro whose inhabitants were broadly known as the Slavs.
b These distinct Slavic nationalities struggled to establish their own identity and independence, thus the area became an arena of fierce conflict.

During the eve of the First World War, the Balkans were the scene of conflict between Serbia and Austria Hungary. During the early part of the 20 th century, Austria Hungary had annexed Bosnia Herzegovina, a territory in the Balkans.Bosnia had a substantial Serb population. So Serbia, with the aid of its ally, Russia, actively aided the independence movement in Bosnia against Austria Hungary. This created animosity between Serbia and Austria Hungary.

The tension between ​Serbia and Austria Hungary led to the assassination of Archduke Franz Ferdinand, the prince of Austria Hungary, on June 28, 1914, in Sarajevo, the capital of Bosnia Herzegovina. The assassin was a Bosnian Serb. Angered by the assassination, Austria Hungary declared war on Serbia. Serbia's ally, Russia, then declared war of Austria Hungary. This was the beginning of the First World War.
