In 2000, the United Nations Security Council adopted Resolution 1325 on Women, Peace, and Security (WPS) in recognition of the critical role that women play in achieving sustainable international peace and security. The WPS agenda also provides a framework for the inclusion of gendered perspectives and the full participation of women in peace processes and conflict prevention efforts. Over 100 countries have developed National Action Plans on WPS, including the United States, which is one of the few countries that has also codified the agenda into law. New Lines’ WPS project seeks to contribute to the expansion and acceleration of the agenda by providing policy analysis and recommendations for WPS practitioners around the world. The WPS Project also provides a bridge between government agencies and civil society organizations working on issues related to WPS.
