Taking a socio-historical perspective, this book examines the growing role of transnational Islamic Non-State Actors (NSAs) in post-authoritarian Indonesia and how it has affected the making of Indonesia's foreign policy since the country embarked on the democratization process in 1998. Providing original research in Asian Studies, while filling an empirical gap in international relations theory, this book will be of interest to scholars of Indonesian Studies, Islamic Studies, International Relations and Asian Politics.
