Transnational Actors in War and Peace provides a comparative examination of a range of transnational actors who have been key to the conduct of war and peace promotion, and of how they interact with states and each other. It explores the identities, organization, strategies and influence of transnational actors involved in contentious politics, armed conflict, and peacemaking. While the study of transnational politics has been a rapidly growing field, to date, the disparate actors have not been analyzed alongside each other, making it difficult to develop a common theoretical framework or determine their influence on international security. This book brings together a diverse set of scholars focused on a range of transnational actors, such as: 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 in this work intended for those interested in security studies, international relations, conflict resolution, and global governance.
