Transnational Actors in War and Peace is the first book to provide a comparative examination of the identities, organization, strategies, and influence of transnational actors involved in contentious politics, armed conflict, and peacemaking. The groups examined include foreign fighters, terrorists, private military security companies, religious groups, diasporas, NGOs, and women's peace groups. Malet and Anderson provide the standard for future study of transnational actors with this essential resource for scholars and students of security studies, international relations, conflict resolution, and global governance.
