ABSTRACT
This chapter focuses on the United Kingdom's roles in relation to the evolution of United Nations (UN) peacekeeping doctrine-or at least its major principles and guidelines given that the UN has yet to write formal doctrine for its peacekeepers. It does so by analyzing the evolution of the United Kingdom's experiences in UN peacekeeping operations and how these influenced British military doctrine relevant to peacekeeping. The chapter provides a broadly chronological approach in order to illustrate the sometimes interrelated nature of the debates. This covers the largely ambivalent approach to peacekeeping doctrine through the Cold War, and the transformation of British approaches to peacekeeping doctrine. The chapter briefly discusses the British input on relevant thematic issues, including on the protection of civilians and sexual violence in armed conflict. It offers a summary of the debates that emerged about the United Kingdom's contribution to UN peacekeeping operations after the withdrawal of its troops from Afghanistan in October 2014.
