Following periods of protracted violence, peacebuilding often takes shape in the form of constitutional agreements, laying out a path for co-operation and tolerance between former warring factions. A common method that has been applied in a variety of states is consociationalism. Initially set forth by political scientist Arend Lijphart, consociationalism calls for a power-sharing form of democracy. Identified by four aspects: grand coalition, mutual veto, proportionality and segmental autonomy; it aims to generate peace across societies that have been torn apart by their internal divisions. Ultimately, consociationalism aims to create a stable society that is able to outlast and overcome differences that may remerge. Examples of consociational agreements can be seen in Northern Ireland, Bosnia and Herzegovina and Lebanon.
