This edited volume affords conceptual and analytical convergence in the study of political incivility by bringing together theoretical and empirical work of scholars from various (sub)disciplines studying political incivility within European countries and the USA. It addresses the needs and challenges of comparative research, adding to a more generic theory on political incivility. Recent years have witnessed growing attention to issues of political incivility in the parliamentary, electoral and media arenas, with rudeness, hostility and vulgarity being highly prevalent in interactions between politicians, journalists and citizens. This book analyses what constitutes this political incivility, its occurrence, causes and effects in these various arenas, using several country-specific contexts, and presenting a cohesive edifice of knowledge on political incivility. This book will be of key interest to scholars and students of parliamentary studies, political behaviour, political communication and political psychology, as well as more broadly to political science, communication science, media studies, psychology, sociology and to (non-) governmental institutions and those that are concerned about the quality of democracy or public debate.
