Bosnia and Herzegovina, country situated in the western Balkan Peninsula of Europe. The larger region of Bosnia occupies the northern and central parts of the country, and Herzegovina occupies the south and southwest. These historical regions do not correspond with the two autonomous political entities that were established by the internationally brokered Dayton Accords of 1995: the Republika Srpska (Bosnian Serb Republic), located in the north and east, and the Federation of Bosnia and Herzegovina, occupying the western and central areas. The capital of the country is Sarajevo; important regional cities include Mostar and Banja Luka. The land has often felt the influences of stronger regional powers that have vied for control over it, and these influences have helped to create Bosnia and Herzegovina’s characteristically rich ethnic and religious mix. Islam, Orthodox Christianity, and Roman Catholicism are all present, with the three faiths generally corresponding to three major ethnic groups: Bosniaks, Serbs, and Croats, respectively. This multiethnic population, as well as the country’s historical and geographic position between Serbia and Croatia, has long made Bosnia and Herzegovina vulnerable to nationalist territorial aspirations.
