The Federation of Bosnia and Herzegovina (, Cyrillic script: Федерација Босне и Херцеговине) is one of the two political entities that compose the sovereign country of Bosnia and Herzegovina (the other entity is the Republika Srpska). The two entities are delineated by the Inter-Entity Boundary Line. The Federation of Bosnia and Herzegovina is inhabited primarily by Bosniaks and Bosnian Croats, which is why it is sometimes informally referred to as the Bosniak-Croat Federation (with the Bosnian Serbs as the third constituency of the entity).
