Dayton Peace Agreement (1995)
The accord ended the 1992-95 war, dividing Bosnia into the Bosniak-Croat Federation and the Serb-led Republika Srpska. It created a rotating tripartite presidency and a power-sharing parliament.
The war stopped, but the new constitutional system locked in ethnic quotas for top offices.
Three decades later, the same two-entity structure still governs every election and coalition.
The October 4 vote is run entirely under the Dayton system, with the same ethnic blocs competing for the same seats.
