Turning Points: Challenges for Western Democracies in the 21st Century centers around the strikingly under-researched concept of turning points and its application in political science, including various theories, fields, and sub-disciplines. The chapters provide theoretical discussion and conceptual clarity by distinguishing a set of turning points at different analytical levels. Based on a wide range of case studies, the authors illustrate where, when and how different types of turning points occur (or not) against the backdrop of current challenges in and for Western democracies. The conceptual and empirical variety of the volume allows scholars and practitioners in policymaking to develop and apply their own frameworks when dealing with turning point dynamics.
