### Balkan Wars and Territorial Expansion
As king, Peter I led Serbia through the Balkan Wars (1912–1913), where Serbia achieved significant territorial gains, including Kosovo, Vardar Macedonia, and parts of Old Serbia. These victories expanded Serbia’s influence in the Balkans and positioned it as a regional power.
