Bosnia and Herzegovina fell under Austro-Hungarian rule in 1878, when the Congress of Berlin approved the occupation of the Bosnia Vilayet, which officially remained part of the Ottoman Empire. Three decades later, in 1908, Austria-Hungary provoked the Bosnian Crisis by formally annexing the occupied zone, establishing the Condominium of Bosnia and Herzegovina under the joint control of Austria and Hungary.

Bosnia and Herzegovina, sometimes known as Bosnia-Herzegovina and informally as Bosnia, is a country in Southeast Europe, situated on the Balkan Peninsula.

In the south it has a 20 kilometres long coast on the Adriatic Sea, with the town of Neum being its only access to the sea.

In the central and eastern regions, the geography is mountainous, in the northwest it is moderately hilly, and in the northeast it is predominantly flat.
