Summary of UN Peacekeeping: History, Principles, and Challenges

## Introduction UN peacekeeping is the primary tool the United Nations uses when conflict prevention has failed and states or parties require an international presence to stabilize situations, monitor agreements, and protect civilians. Although not explicitly mentioned in the UN Charter, peacekeeping has evolved since 1956 into a variety of mission types with distinct principles, tasks, and political implications. > Definition: Peacekeeping refers to the deployment of international military, police, and civilian personnel authorized by the UN to help maintain or restore peace and security, usually between or within states following a ceasefire or peace agreement. ## 1. Historical development: generations of peacekeeping ### First generation (1956–1990): Traditional peacekeeping - Origin: UNEF I after the Suez Crisis (1956). The Security Council failed to act, and the General Assembly created UNEF I to supervise withdrawal and separate forces. - Core features: - Consent of the parties - Political neutrality and impartiality - Non-use of force except in self-defence - Mandates to monitor ceasefires, supervise withdrawals, and act as buffer zones - Example: UNEF I (Suez), UNTAG (Namibia, 1989–1990): supervised withdrawal of foreign forces, return of refugees and free elections. > Definition: Traditional peacekeeping is the classic model based on consent, impartiality, and limited use of force to monitor and maintain ceasefires. ### Second generation (post-Cold War expansion, early 1990s) - Characteristics: Missions broadened into multidimensional roles, addressing security, humanitarian assistance, and political objectives inside states during internal conflicts. - Tasks added: civilian protection, disarmament, electoral support, human rights monitoring, and institution-building. - Why it struggled: Lightly armed contingents were given robust civilian-protection and state-building tasks without sufficient authority or resources. - Key failures: Somalia (1993), Rwanda (1994), Srebrenica (1995). These exposed limits of consent, strict neutrality, and constrained use of force. ### Third generation (1995–2015): Robust peace operations - Response: Mandates became more robust and often invoked Chapter VII authority, allowing stronger use of force for protection and enforcement. - Effects: Erosion of some traditional principles (consent, strict neutrality) and debates over who enforces peace and under what legitimacy. - Trend: Greater focus on protection of civilians and integrated civilian-military operations. ### Fourth generation (2015–present): Political and sustaining-peace focus - Shift: Fewer traditional peacekeeping missions; growth in political missions and “sustaining peace” approaches emphasizing prevention and long-term peacebuilding. - Key milestones: HIPPO Report (2015) — lasting peace is political; Sustaining Peace resolutions (2016); Action for Peacekeeping — A4P (2018) and the 2023 New Agenda for Peace. - Current profile: Around 11 peacekeeping missions and over 45 political missions globally (figures vary over time). Fun fact: UN peacekeepers introduced the distinctive blue helmets and blue berets during UNEF I to visually separate peacekeepers from combatants. ## 2. Legal and conceptual placement in the UN Charter - Chapter VI: Peaceful settlement of disputes (negotiation, mediation, arbitration). - Chapter VII: Enforcement measures, including the use of coercion and force to maintain or restore international peace and security. - Peacekeeping often sits between these chapters and is colloquially called “Chapter VI ½” because it combines consent-based, neutral presence with, in some missions, limited enforcement powers. ## 3. Core principles of traditional peacekeeping - Consent of the parties - Political neutrality - Impartiality - Non-use of force except for self-defence - Legitimacy: UN authorization and accountability to the Security Council and Secretary-General > Definition: Consent means that
