Party systems are crucial elements for the functioning of political systems and representative democracies. With several European countries experiencing significant changes recently, it is necessary to update our knowledge. This volume analyses party system changes in Europe in the 21st century by considering several dimensions such as interparty competition, the cleavage structure, electoral volatility and the emergence of new actors. The book describes the principal continuities and changes in party systems in Europe; analyzes the main explanations for these trends; and assesses the impact of the crisis on the patterns observed. By considering a wide range of Western and Eastern European countries, and focusing on the ‘parameters’ of party system change, this book seeks to fill an important gap in the literature through a comparative analysis of the evolution of party systems in Europe over the last decades. This book will be of key interest to scholars and students of political parties, party systems and politics, electoral behavior as well as more broadly to European politics, comparative politics. political representation and the quality of democracies.

In this book, Carol Mershon and Olga Shvetsova explore one of the central questions in democratic politics: how much autonomy do elected politicians have to shape and reshape the party system on their own, without the direct involvement of voters in elections? Mershon and Shvetsova's theory focuses on the choices of party membership made by legislators while serving in office. It identifies the inducements and impediments to legislators' changes of partisan affiliation, and integrates strategic and institutional approaches to the study of parties and party systems. With empirical analyses comparing nine countries that differ in electoral laws, territorial governance and executive-legislative relations, Mershon and Shvetsova find that strategic incumbents have the capacity to reconfigure the party system as established in elections. Representatives are motivated to bring about change by opportunities arising during the parliamentary term, and are deterred from doing so by the elemental democratic practice of elections.

Mair examines how we interpret the evidence of change and stability in modern parties and party systems. Focusing on processes of political adaptation and control, he also looks at how parties generate or freeze their own momentum.

This volume examines the recent changes which have occurred in party systems across Europe. It concludes that parties in many countries are no longer bare reflections of traditional social groups. Rather, the structure in which parties compete is increasingly open and flexible, and subject to on-going change. The combination of comparative and individual case-studies provides strong evidence that political parties remain a potent, if changing, force in politics throughout Europe.

′This thoughtful and wide-ranging review of parties and party research contains contributions from many of the foremost party scholars and is a must for all library shelves′ - Richard Luther, Keele University ′The study of political parties has never been livelier and this genuinely international Handbook – theoretically rich, comparatively informed, and focused on important questions – defines the field. This volume is both an indispensable summary of what we know and the starting point for future research′ - R K Carty, University of British Columbia ′Political parties are ubiquitous, but their forms and functions vary greatly from regime to regime, from continent to continent, and from era to era. The Handbook of Party Politics captures this variation and richness in impressive ways. The editors have assembled an excellent team, and the scope of the volume is vast and intriguing′ - Kaare Strom, University of California, San Diego Political parties are indispensable to democracy and a central subject of research and study in political science around the world. This major new handbook is the first to comprehensively map the state-of-the-art in contemporary party politics scholarship. The Handbook is designed to: - provide an invaluable survey of the major theories and approaches in this dynamic area of study and research - give students and researchers a concise ′road map′ to the core literatures in all the sub-fields of party related theorizing and research - identify the theories, approaches and topics that define the current ′cutting edge′ of the field. The Handbook is comparative in overall approach but also addresses some topics to be addressed in nationally or regionally specific ways. The resulting collaboration has brought together the world′s leading party theorists to provide an unrivalled resource on the role of parties in the pressing contemporary problems of institutional design and democratic governance today.

This book generates a wealth of new empirical information about Latin American party systems and contributes richly to major theoretical debates about party systems and democracy.

How do political parties affect foreign policy? This book answers this question by exploring the role of party politics as source of foreign policy change in liberal democracies. The book shifts the focus from individual political parties to party systems as the context in which parties’ ideologies receive precise content and their preferences are formed. The central claim is that foreign policy change arises from within transformed discursive contexts of party competition, when a new language of politics that constitutes anew parties’ self-understanding of what they stand for and compete over emerges in a party system. By comparing cases of contested foreign policy change, the book shows how such transformations in party competition determine whether and when international pressures on a state will translate into decisions to institute foreign policy change and what degree of change will be ultimately implemented. With a novel framework which bridges concepts of international relations and comparative politics, the book will be of interest to researchers and students in the areas of international relations theory, foreign policy analysis and comparative politics, and generally to anyone wanting to understand how and when parties, elections and voters contribute to international change.
