2019 was a defining year for the radical right globally. From national and supranational elections that witnessed a surge in support for radical right parties to transnationally-inspired terrorist attacks in New Zealand, the USA, and Germany, the radical right is not just on the rise, but becoming an international mainstream phenomenon. The yearbook draws upon insightful analyses from an international network of scholars, policymakers, and practitioners who explore the processes and impact of the radical right. Beginning with reflections on the ideology and then historical perspectives of the radical right, the volume then turns to contemporary manifestations of movements and political parties as well as terrorism and the role of online spaces. It ends by examining various perspectives towards countering and challenging the radical right. This overview provides a widespread examination of the global radical right in 2019, which will be useful to scholars, students, policy makers, and the public.
