Sanjak of Bosnia (Turkish: Bosna Sancağı, Bosanski sandžak / Босански санџак) was one of the sanjaks of the Ottoman Empire established in 1463 when the lands conquered from the Bosnian Kingdom were transformed into a sanjak and Isa-Beg Isaković was appointed its first sanjakbey.[1] In the period between 1463 and 1580 it was part of the Rumelia Eyalet. After the Bosnia Eyalet was established in 1580 the Bosnian Sanjak became its central province.[2] Between 1864 and the Austro-Hungarian occupation of Bosnia in 1878 it was part of the Bosnia Vilayet that succeeded the Eyalet of Bosnia following administrative reforms in 1864 known as the "Vilayet Law". Although Bosnia Vilayet was officially still part of the Ottoman Empire until 1908 the Bosnian Sanjak de facto ceased to exist in 1878; when it was occupied by Austria-Hungary.
Banja Luka became the seat of the Sanjak of Bosnia some time prior to 1554, until 1580 when the Bosnia Eyalet was established. Bosnian beylerbeys were seated in Banja Luka until 1639.[3]
Apostolic visitor Peter Masarechi claimed in his 1624 report that the population of Bosnia was 450,000 Muslims, 150,000 Catholics, and 75,000 Orthodox.[4]
