The passing of the landmark Security Council Resolution 1325 in 2000 made women’s participation across the spectrum of peace and conflict prevention efforts an essential part of international security. This has changed the landscape of international policy and practice, bringing gender concerns more centrally in focus across a range of peace and security, development, humanitarian and human rights issues. Creating a heightened policy conscience around these issues has been an ongoing effort of scholars and practitioners in peacebuilding and development. This special issue of JPD is being launched during this tenth anniversary year, a time of international celebrations of this important resolution. As many participants in events at the United Nations and elsewhere marking the anniversary have shown, however, there is much work to be done at the local and national levels to realise the real potential of Resolution 1325. This issue aims to contribute to thinking about needed efforts.
