About Peacemaker


UN Peacemaker is an online mediation support tool developed by the Mediation Support Unit (MSU) in the Policy and Mediation Division of the Department of Political Affairs (DPA).

Intended for peacemaking professionals, it includes an extensive database of peace agreements, guidance material and information on the UN’s mediation support services.


UN Peacemaker is part of the UN’s overall effort to provide advice and support to the Secretary-General and his Representatives in their efforts to resolve international disputes and internal conflicts. It is also intended to be useful to UN partners actively engaged in peacemaking efforts, including Member States, regional organisations, civil society, non-governmental organisations and national mediators.


Re-launch in 2012


Initially launched in 2006, UN Peacemaker is the product of a multi-year learning project drawing on DPA’s leadership and experience in peacemaking and preventive diplomacy.

In the summer of 2011, MSU initiated an end-user analysis in partnership with Swisspeace. In order to adapt UN Peacemaker to the emerging needs of the mediation community, MSU undertook a comprehensive overhaul and update of the website, which was re-launched in 2012. UN Peacemaker has one of the most comprehensive databases of peace agreements with an advanced search function.



Intended to support peacemakers in their efforts to manage peace processes and negotiate peace agreements, the website offers key tools and resources such as:

  • A comprehensive database of more than 750 peace agreements.
  • Guidance documents on mediation.
  • Information on UN mediation support activities and services.
  • A library of selected literature on key mediation issues (e.g. power-sharing,
    wealth-sharing, constitutional issues, mediation processes and strategies etc.).


MSU will also be adding video interviews with mediation experts discussing strategies and tactics on how to manage mediation processes and providing guidance on specific themes.


The overhaul of UN Peacemaker was made possible by the generous support of the governments of Canada, Finland, Germany and Ireland. The website was developed and designed in collaboration with PASTPRESENTFUTURE.
