Sanjak of Bosnia

Today part of

The Sanjak of Bosnia (Turkish: Bosna Sancak; Serbo-Croatian: Bosanski sandžak / Босански санџак) was one of the sanjaks of the Ottoman Empire. It was established in 1463, after the lands conquered from the Kingdom of Bosnia were transformed into a sanjak. Its first sanjakbey was Isa Bey Ishaković.

Between 1463 and 1580, it was part of the Rumelia Eyalet. Due to its strategic position on the border, it functioned as a krajište (frontier province), serving as a military base for Ottoman raids into Hungary and Croatia.

After the Bosnia Eyalet was established in 1580, the Sanjak of Bosnia became its central and main province. Between 1864 and the Austro-Hungarian occupation in 1878, it was part of the Bosnia Vilayet. Although the Bosnia Vilayet formally remained part of the Ottoman Empire until 1908, the Sanjak of Bosnia de facto ceased to exist in 1878.
