The First Balkan War, which lasted from October 1912 to May 1913, pitted the Balkan League (Serbia, Greece, Montenegro and Bulgaria) against the Ottoman Empire. The combined armies of the Balkan states overcame the numerically inferior and strategically disadvantaged Ottoman armies and achieved rapid success.
