The leadership profiles collected in this volume are generated from the work of undergraduate students in a course entitled Leadership for Social Justice, in the Department of Justice and Peace Studies at the University of St. Thomas, Minnesota, USA. Each profile follows a common format: story, theory, collective action, biography, and references. They explore peacebuilding work in local neighborhood contexts and in global social movements. They are stories of inspirational leadership found in individual organizers and in dynamic organizations. Students strive to represent voices authentically and describe peacebuilding responsibly, to encourage and inspire readers to enact their own leadership for social justice.
