Due to rapid changes and unexpected developments, academic studies of international politics are becoming increasingly complex. In order to examine constantly shifting objects of study, research on international politics must continually revise the theoretical and empirical frameworks and methodology employed. Moreover, both academic research in general and international politics studies in particular should go beyond mere analysis and offer normative guidance to policy makers. The challenges of such a multilevel field of research can only be met by an interdisciplinary approach, in which important insights from both political science and philosophy are applied to studies of topics ranging from armed conflicts, political and religious extremism, migration, identity issues, contested economic structures and regulations, and international law-making to humanitarian intervention and climate change. This book series consists of anthologies of works by philosophers and political scientists and experts from related subjects as well as monographs written by authors with the respective disciplines as a background. All texts submitted for publication in this series undergo a rigorous process of double-blind peer review, based on initial editor screening and anonymized refereeing by at least two referees. The editorial process is overseen by the editors and supported by two editorial assistants.
