First Balkan War: Kardzhali is liberated by Bulgarian forces.

Kardzhali (Bulgarian: [krdli], Krdali; Turkish: Krcaali; Greek: , Krtzali), sometimes spelt Kardali or Kurdzhali, is a town in the Eastern Rhodopes in Bulgaria, centre of Kardzhali Municipality and Kardzhali Province. The noted Kardzhali Dam is located nearby.

The First Balkan War (Serbian: Први балкански рат, Prvi Balkanski rat; Bulgarian: Балканска война; Greek: Αʹ Βαλκανικός πόλεμος; Turkish: Birinci Balkan Savaşı) lasted from October 1912 to May 1913 and involved actions of the Balkan League (the Kingdoms of Bulgaria, Serbia, Greece and Montenegro) against the Ottoman Empire. The Balkan states' combined armies overcame the initially numerically inferior (significantly superior by the end of the conflict) and strategically disadvantaged Ottoman armies and achieved rapid success.

The war was a comprehensive and unmitigated disaster for the Ottomans, who lost 83% of their European territories and 69% of their European population. As a result of the war, the League captured and partitioned almost all of the Ottoman Empire's remaining territories in Europe. Ensuing events also led to the creation of an independent Albania, which angered the Serbs. Bulgaria, meanwhile, was dissatisfied over the division of the spoils in Macedonia, and attacked its former allies, Serbia and Greece, on 16 June 1913 which provoked the start of the Second Balkan War.
