On 28 June 1914 the Archduke Francis Ferdinand, heir-presumptive to the Hapsburg throne, was shot in the streets of Serajevo, the capital of the Austrian province of Bosnia. Redeemed by the Russo-Turkish war of 1876-7 from Ottoman rule, Bosnia had by the Congress of Berlin in 1878 been entrusted to Austrian administration; but in 1908, fearing lest a Turkey rejuvenated by the Young Turk revolution should seek to revive its claims on Bosnia, the Austrian Government annexed on its own authority a province confided to its care by a European mandate. This arbitrary act was only challenged on paper at the time; but the striking success of Serbia in the Balkan wars of 1912-13 brought out the dangers and defects of Austrian policy.
