The Balkan Wars (1912–1913) — Causes, Events and Impact on World War I
The Balkan Wars (1912–1913) were two consecutive wars fought in the Balkans region of Europe. These wars significantly weakened the Ottoman Empire and intensified rivalries among Balkan states, creating the conditions that eventually led to World War I.
The wars involved several countries including Serbia, Bulgaria, Greece, and Montenegro.
Background of the Balkan Wars
For centuries, much of the Balkan region was ruled by the Ottoman Empire. By the early 20th century, the empire was weakening, and many Balkan nations wanted independence and territorial expansion.
At the same time, strong nationalist movements were emerging in the region.
Countries such as Serbia, Bulgaria, Greece, and Montenegro wanted to:
Expand their territories
Free ethnic groups from Ottoman controlBecome dominant powers in the Balkans
These ambitions led to the formation of a military alliance known as the Balkan League.
First Balkan War (1912–1913)

Main Objective
To remove Ottoman rule from Europe.

The war ended with the Treaty of London (1913).
