The political system of Bosnia and Herzegovina is a complex structure established by the Dayton Agreement in 1995. It consists of two main entities: the Federation of Bosnia and Herzegovina and the Republika Srpska, along with a third region, the Brčko District. Each entity has its own government and administrative powers, while the central government oversees national matters. The country operates under a parliamentary democracy, with a tripartite presidency representing the three main ethnic groups: Bosniaks, Croats, and Serbs. The presidency rotates among these groups every eight months, ensuring representation. The legislative body is the Parliamentary Assembly, which consists of two chambers: the House of Representatives and the House of Peoples.
