The fi rst UN peacekeeping operations deployed during the Cold War area were mainly composed of military personnel in charge of observing compliance with ceasefi res agreed between former warring states. In the 1990s, the concept of peacekeeping evolved to encompass larger missions, including a civilian component, with a mandate to implement peace accords between intra-state stakeholders. Today’s multidimensional peacekeeping operations in post-confl ict situations are involved in a wide range of activities: restoring peace in a volatile security environment; organizing elections; disarming and reintegrating former combatants; monitoring human rights; consolidating the rule of law; working on good governance and so on.
