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 formally annexing it.
