The Bosnia Vilayet (Serbo-Croatian: Bosanski vilajet / ÃÂþÃÂðýÃÂúø òøûðÃÂõÃÂ; Ottoman Turkish: ÃÂÃÂçÃÂê èÃÂóÃÂÃÂ, Vilâyet-i Bosna) was a first-level administrative division (vilayet) of the Ottoman Empire, mostly comprising the territory of the present-day state of Bosnia and Herzegovina, with minor parts of modern Montenegro and Serbia.
It was formed in 1867 following the administrative reforms of the Tanzimat period, which transformed the former Bosnia Eyalet into a vilayet. It effectively ceased to exist as an Ottoman-administered province after the Austro-Hungarian campaign in Bosnia and Herzegovina in 1878, though it formally remained part of the Ottoman Empire for thirty more years until 1908. During this period, it was governed by Austria-Hungary as a condominium. In 1908, during the Bosnian Crisis, Austria-Hungary formally annexed the territory.
