Bosnia was a secondary constituent of the Austro-Hungarian Dual Monarchy under the control of the Austrian Crown. It is now part of the autonomous country of Illyria.
The Treaty of Berlin in 1878 forced the Ottomans to cede administration of Bosnia to Austria-Hungary. A state of relative stability was reached soon enough and Austro-Hungarian authorities were able to embark on a number of social and administrative reforms. With the aim of establishing the province as a stable political model that would help dissipate rising South Slav nationalism, Habsburg rule did much to codify laws, to introduce new political practices and generally to provide for modernization. The Austro-Hungarian policy, which advocated the ideal of a pluralist and multi-confessional Bosnian nation, was largely favored by the Muslims and its economical success also helped soothing the rising tides of nationalism.
Austria-Hungary decided to annex Bosnia in October 1908 as a common holding under the control of the Finance ministry, rather than attaching it to either territorial government. This decision once again rised the soothed nationalism and worsened the relations between Austria-Hungary and Russia. The political tensions culminated on June 28 1914, when the heir to the Austro-Hungarian throne, Archduke Franz Ferdinand, was assassinated in Sarajevo; an event that proved to be the spark that set off the Weltkrieg. Although some Bosnians died serving in the armies of the various warring states, Bosnia itself managed to escape the conflict relatively unscathed.
Bosnia became a constituent part of Austria-Hungary. Emperor Otto I von Habsburg was represented by Governor Georg Dragicevic and the government was led by Minister-President Osman Zulfikarpasic.
During the renegotiations of the Ausgleich in 1927, Bosnia was merged with Croatia and the newly annexed Montenegro to form the Kingdom of Illyria as an autonomous country within the empire, with Stjepan Radić as the country's head of state.
