Bosnia (region)
The Ottoman Empire initially expanded into Bosnia and Herzegovina through a territory called the Bosansko Krajište. It was transformed into the Sanjak of Bosnia and the Sanjak of Herzegovina after 1462/1463. The first Ottoman administration called Eyalet of Bosnia was finally formed in 1527, after long armed resistance to the north and to the west by Counts Franjo and Ivaniš Berislavić of the noble house of Berislavići Grabarski.
