Bosnia and Herzegovina has a bicameral legislature and a three-member presidency made up of one member from each of the three major ethnic groups. However, the central government's power is highly limited, as the country is largely decentralized. It comprises two autonomous entities—the Federation of Bosnia and Herzegovina and Republika Srpska—and a third unit, the Brčko District, which is governed by its own local government. The Federation of Bosnia and Herzegovina furthermore consists of 10 cantons.
