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. Eventually, following the Great Turkish War, in the 18th century the Eyalet came to encompass the area largely matching that of today's Bosnia and Herzegovina. In 1833, the Eyalet of Herzegovina was temporarily split off under Ali-paša Rizvanbegović. The area acquired the name of "Bosnia and Herzegovina" in 1853 as a result of a twist in political events following his death. After the 1864 administrative reform, the province was named Vilayet of Bosnia. Austria-Hungary occupied the whole country in 1878. It remained formally part of the Ottoman Empire under the title of Condominium of Bosnia and Herzegovina until 1908, when Austria-Hungary provoked the Bosnian crisis by formally annexing the province. Regional identity Within Bosnia and Herzegovina, the region of Bosnia has a traditional regional identity, distinctive from the regional identity of the neighboring Herzegovina. Bosnian regional identity was attested as early as the 10th century, when Constantin VII Porphyrogenetos referred to Bosnia as a particular region. Development of Bosnia's regional identity continued throughout the Middle Ages, and it was also acknowledged in the 15th century by the Ottoman conquerors, who created the Sanjak of Bosnia in 1463, giving it a regional name, which was not always the case. By the end of the Ottoman rule (1878), regional Bosnianhood became a distinctive mark of local identity, that transcended traditional ethnic and religious distinctions within the general population of Bosnia, and the same notion of regional Bosniandom was preserved throughout the periods of Austro-Hungarian (1878-1918) and Yugoslav (1918-1992) rule.
