query: Where is Bosnia?
passage: Bosnia (region)
Bosnia (Serbo-Croatian: Bosna/Босна; pronounced[bɔ̂sna]) is the northern region of Bosnia and Herzegovina, encompassing roughly 81% of the country; the other eponymous region, the southern part, is Herzegovina. Bosnia is an informal term for the whole country.
passage: Ottoman Bosnia and Herzegovina
The area of the current Bosnia and Herzegovina was initially part of the Ottoman Rumelia Province (beylerbeylik) and was divided between the three sanjaks (second-level administrative units) of Bosnia (Bosna), Herzegovina (Hersek), and Zvornik (İzvornik). In 1580, the Ottomans created the Bosnia Eyalet which was subdivided into the sanjaks of Bosnia and Herzegovina, among others. They also introduced the so-called spahi system (actually the timar holder system) which changed the local administration and the agriculture, but was generally an arrangement similar to European feudal fiefs.
