For more than four decades, IPS has transformed ideas into action for peace, justice, and the environment. The Institute has strengthened and linked social movements through articulation of root principles and fundamental rights, research and analysis on current events and issues, and connections to policymakers, academics, and activists at all levels. As a multi-issue think tank that has worked with the movements that shaped the late 20th Century, from Civil Rights onwards, we offer a cross-cutting analysis with a historical perspective.
