100 years ago today, on 6 October 1908, Austria-Hungary formally annexed the Turkish province of Bosnia-Herzegovina. The province had been administered by Austria since 1878 whilst remaining part of the Ottoman Empire. Austria was looking to expand in that area and to replace Turkey as the dominant power in the Balkans. The annexation had profound consequences as it aroused bitter feelings amongst the Balkan states, Serbia in particular, and Russia who also wished to expand in the Balkans. It meant that if another situation arose it would be impossible to dampen down Slavic feelings. The events of the summer of 1914 stemmed directly from Austria's actions in October 1908.
