This volume offers an up-to-date overview of the much-debated issue of how a democracy may defend itself against those who want to subvert it. The justifications, effectiveness and legal implications of militant democracy are discussed by addressing questions as: How can militant democracy measures such as party bans be justified? Why is it that some democracies ban antidemocratic parties? Does militant democracy succeed in combatting right-wing extremism? And is militant democracy evolving into an internationalized legal and political concept? Bringing together experts and perspectives from political science, law and philosophy, this volume advances our understanding of the current threats to democracy, a political system once thought almost invincible. It is especially timely in the light of the rise of illiberal democracy in the EU, the increasingly authoritarian rule in Turkey, the steady shift to autocracy in Russia and the remarkable election of Trump in the US.

This book aims to present a comprehensive theory of militant democracy and to answer questions such as: How can a democracy protect itself against its own downfall? And when is intervention against antidemocrats justified? Against the backdrop of historical and current examples, this book examines a variety of theories from philosophers and legal scholars such as Karl Loewenstein, Karl Popper and Carl Schmitt as well as contemporary alternatives. It compares their interpretations of democracy and militant democracy, discusses how helpful these references are, and introduces two largely forgotten theorists to the militant democracy debate: George van den Bergh and Milan Markovitch. Militant Democracy then sets out to build a novel theory of democratic self-defence on the basis of democracy's capacity for self-correction. In doing so, it addresses the more classic and current criticisms of the concept, while paying specific attention to the position of the judge, the legal design and effectiveness of party bans, and the national and supranational procedural safeguards that can safeguard the careful application of militant democracy instruments. Militant Democracy seamlessly combines political philosophy, political science and constitutional law to offer a new perspective on democratic self-defence. This book is essential reading for scholars and students of political theory, jurisprudence, democracy, extremism and the history of ideas.
