In October 2017, the United States passed the Women, Peace, and Security Act, a piece of landmark legislation that recognizes women as powerful agents of change in peace and security operations. This legislation came into being thanks to the efforts of the US Civil Society Working Group and seeks to make the US a global leader in promoting women’s active engagement in conflict prevention, relief, and recovery. Originally published in 2018, this policy brief includes 2023 updates on the United States WPS Act and serves as a guide on the history, implementation, and funding of the act.
