This article argues that mediation by special representatives of the Secretary-General (SRSGs) in civil wars involves a distinctly clear strategic purpose: by conducting international mediation and managing international assistance, SRSGs structure the incentives for parties in conflict to exchange the battlefield with a reformed, renewed, or created state. The article offers a substantive introduction to a special-focus section of this issue of Global Governance on the role of the SRSGs in mitigating civil wars. The introduction describes the often conflicted and multilayered role that these individuals play in managing the mediation process, serving as the principal for large-scale UN peacekeeping or political missions, in navigating within the Secretariat and in relation to the Security Council, and in coordinating on-the-ground a panoply of international organizations, regional organizations, donor agencies, and humanitarian or other nongovernmental organizations. The article concludes with three principal issues that consideration of SRSG roles in civil war termination raises: choice, context and conduct. In sum, for more effective leadership management of efforts to end civil wars, the roles and functions of the SRSGs need to become more institutionalized.
