e to an agreement with Bosnians, tensions remained in certain parts of the country (particularly the south) and a mass emigration of predominantly Slavic dissidents occurred. However, 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 which intended to make Bosnia and Herzegovina into a "model colony".
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 to provide for modernisation. The Austro-Hungarian Empire built the three Roman Catholic churches in Sarajevo and these three churches are among only 20 Catholic churches in the state of Bosnia.
Within three years of formal occupation of Bosnia Herzegovina, Austria-Hungary, in 1881, obtained German, and more importantly, Russian, approval for the annexation of these provinces, at a time which suited Vienna. This mandate was formally ratified by the Dreikaiserbund (Three Emperor's Treaty) on June 18 of that year. Upon the accession of Czar Nicholas II, however, the Russians reneged on the agreement, asserting in 1897 the need for special scrutiny of the Bosnian Annexation issue at an unspecified future date.
External matters began to affect the Bosnian Protectorate, however, and its relationship with Austria-Hungary. A bloody coup occurred in Serbia, on June 10, 1903, which brought a radical anti-Austrian government into power in Belgrade. Serb attempts to foment agitation followed, advocating a unified South Slavic state, ruled from Belgrade. This gained little support amongst most of the population of Bosnia Herzegovina, and only found fertile ground with disaffected portions of the Orthodox minority. Also, the revolt in the Ottoman Empire in 1908, raised concerns that the Istanbul government might seek the outright return of Bosnia
