The Bosnian crisis on 6 October 1908 erupted when Austria-Hungary announced the annexation of Bosnia and Herzegovina, territories formally within the sovereignty of the Empire. This unilateral action was timed to coincide with Bulgaria's declaration of independence (5 October) from the Empire. The Ottoman Empire protested Bulgaria's declaration with more vigour than the annexation of Bosnia-Herzegovina, which it had no practical prospects of governing. A boycott of Austro-Hungarian goods and shops occurred, inflicting commercial losses of over 100,000,000 "kronen" on Austria-Hungary. Austria-Hungary agreed to pay the Ottomans ₤2.2 million for the public land in Bosnia-Herzegovina. Bulgarian independence could not be reversed.
