Map: Austria-Hungary annexes Bosnia-Herzegovina, 6 October 1908
6 OCTOBER 1908 · THE GREAT WAR, 1871–1923

The moment in context

Austria-Hungary had administered Bosnia-Herzegovina since 1878, although the province remained formally Ottoman. In July 1908 the Young Turks, reforming officers, forced the Ottoman sultan to restore a constitution. Vienna feared that a revived Ottoman government might seek to reclaim Bosnia. Its foreign minister, Alois von Aehrenthal, met Russia’s Alexander Izvolsky at Buchlau castle in September. Izvolsky accepted annexation in return for Austrian support for opening the Straits between the Black Sea and Mediterranean to Russian warships. The bargain came apart when Vienna annexed Bosnia in October before Russia had secured passage through the Straits. In March 1909 Germany demanded that Russia recognize the annexation. Russia was unready for war and yielded. Bosnia turns from tan to charcoal on the map; in St Petersburg, an agreement made in private had ended in public humiliation.
