Right-wing populism, right-wing extremism and even right-wing terrorism are a political reality again in Europe today, and have been so for a long time. Almost everywhere, the far right has institutionalised itself in various forms and with varying degrees of strength, and in some countries it even plays a role in determining government policy. What constitutes such right-wing phenomena, and how can their growth in importance be explained? How do they present themselves in individual countries? What role do the Internet and social media play in the spread of radical right-wing ideas? And what strategies exist to counter the dangers from the far right? In order to provide at least preliminary answers to these questions, this volume brings together contributions from various disciplines. As the successor to ‘Rechtspopulismus und Rechtsextremismus’ (Nomos Verlag, 2015), which appeared in the same series, the book has been redesigned, updated and greatly expanded, especially in the sections on individual countries.
