First Balkan War: Greek aviator Emmanouil Argyropoulos becomes the first pilot to die in the Hellenic Air Force when his plane crashes.
Emmanouil Argyropoulos (Greek: ; 1889 4 April 1913) was a Greek pioneer aviator of the early 20th century. Apart from being the first Greek aviator who performed a flight over his homeland. He also became the first casualty of Greek military aviation.
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.
