Abstract: The article discusses the key principles of United Nations peacekeeping. Based on the use of the mechanisms of the Charter of the United Nations, the evolution of the Organization's activities in the field of maintaining international peace and security from the concept of collective security to the modern practice of peacekeeping is shown. Using the example of key documents of the universal Organization and specific United Nations peacekeeping missions, the functioning of the principles of consent of the parties, impartiality and non-use of force, as well as their conceptual changes in the post-bipolar period, is analyzed. The conceptualization of the principles of UN peacekeeping reflects the processes of evolution of the system of international relations in the bipolar and post-bipolar period in general, and the UN in particular. The inability to implement the original ideas laid down in the UN Charter prompted States to develop flexible mechanisms for responding and adapting the Organization to current conditions and moving from the concept of collective security to modern peacekeeping practices; the key principles that laid the foundation for UN peacekeeping operations were gradually formed. Along with the above—mentioned principles — the consent of the parties, impartiality and non-use of force - there are also such fundamental components of the success of peacekeeping operations as general guidance from the founding body, that is, the UN Security Council, as well as the order of management and control over international peacekeeping forces that operate under the leadership of the UN Security Council, but are under the command of the Secretary General. a secretary who speaks on behalf of the UN and has political guidelines from the Security Council.
