The partition of Bosnia and Herzegovina was discussed and attempted during the 20th century. The issue came to prominence during the Bosnian War, which also involved Bosnia and Herzegovina's largest neighbors, Croatia and Serbia. As of 2016[update], the country remains one state while internal political divisions of Bosnia and Herzegovina based on the 1995 Dayton Agreement remain in place.
Bosnia and Herzegovina has been a single entity occupying roughly the same territory since the rise of the medieval Kingdom of Bosnia and the subsequent Ottoman conquest of Bosnia between the 1380s and 1590s. The borders of today's Bosnia and Herzegovina were largely set as the borders of the Ottoman-era Eyalet of Bosnia, fixed in the south and west by the 1699 Treaty of Karlowitz, in the north by the 1739 Treaty of Belgrade, and in the east by the 1878 Treaty of Berlin.
Although formally under Ottoman sovereignty, Austria-Hungary occupied the territory and created the Condominium of Bosnia and Herzegovina in 1878 before officially annexing it in 1908. Following World War I and the dissolution of Austria-Hungary, the territory passed in whole to the newly formed Kingdom of the Serbs, Croats and Slovenes in 1918. In 1922, it was internally divided into six oblasts of the Kingdom of Serbs, Croats and Slovenes.
