Bosnia and Herzegovina came under Austro-Hungarian administration in 1878, when the Congress of Berlin approved the occupation of the Bosnia Vilayet, which officially remained part of the Ottoman Empire. Austria-Hungary constituted the final phase of the long-standing Habsburg Monarchy, following Hungarian wars of independence against Habsburg rule. In 1908, Austria-Hungary provoked the Bosnian crisis by formally annexing the occupied zone, establishing the Condominium of Bosnia and Herzegovina.
