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.

This special issue of the German Political Science Quarterly addresses the transformation and the sustainability of European party democracies, both at the level of party organization as well as party systems and competition. The contributions in this volume are dedicated to these areas of change of European party democracies from different perspectives. It shows which new dynamics of change can be stated and how they can be explained.

This unique and important new book looks at how we interpret the evidence of change and stability in modern parties and party systems. Focusing primarily on processes of political adaptation and control, it also concerns how parties and party systems generate their own momentum and `freeze' themselves into place. Amidst the widespread contemporary discussion of the challenge to modern democracy and the crisis of traditional forms of political representation, it offers a welcome emphasis on how party systems survive, and on how change, when it does occur, may be analysed and understood. The first part of the book deals with questions of persistence and change, and with the vulnerability and endurance of traditional parties. In the second part, attention shifts to the question of party organization, and to the ways in which the established parties are increasingly coming to invade the state, finding there a new source of privilege and a new means of ensuring their own survival. The third part of the book focuses on structures of competition in Western party systems, as well as on the problems associated with the consolidation of the new party systems in post-communist Europe. This is the first book to be entirely devoted to the question of party and party system change, and offers and essential guide to the understanding of this crucial theme.

Party System Closure maps trends in interparty relations in Europe from 1848 until 2019. It investigates how the length of democratic experience, the institutionalization of individual parties, the fragmentation of parliaments, and the support for anti-establishment parties, shape the degree of institutionalization of party systems. The analyses presented answer the questions of whether predictability in partisan interactions is necessary for the survival of democratic regimes and whether it improves or undermines the quality of democracy. The developments of party politics at the elite level are contrasted with the dynamics of voting behaviour. The comparisons of distinct historical periods and of macro-regions provide a comprehensive picture of the European history of party competition and cooperation. The empirical overview presented in the book is based on a novel conceptual framework and features party composition data of more than a thousand European governments. Party systems are analysed in terms of poles and blocs, and the degree of closure and of polarization is related to a new party system typology. The book demonstrates that information collected from partisan interactions at the time of government formation can reveal changes that characterise the party system as a whole. The empirical results confirm that the Cold War period (1945-1989) was exceptionally stable, while the post-Berlin-Wall era shows signs of disintegration, although more at the level of voters than at the level of elites. After three decades of democratic politics in Europe (1990-2019), the West and the South are looking increasingly like the East, especially in terms of the level of party de-institutionalization. The West and the South are becoming more polarised than the East, but in terms of parliamentary fragmentation, the party systems of the South and the East are converging, while the West is diverging from the rest with its increasingly high number of parties. As far as our central concept, party system closure, is concerned, thanks to the gradual process of stabilization in the East, and the recent de-institutionalization in the West and South, the regional differences are declining. Comparative Politics is a series for researchers, teachers, and students of political science that deals with contemporary government and politics. Global in scope, books in the series are characterised by a stress on comparative analysis and strong methodological rigour. The series is published in association with the European Consortium for Political Research. For more information visit: www.ecprnet.eu. The series is edited by Susan Scarrow, Chair of the Department of Political Science, University of Houston, and Jonathan Slapin, Professor of Political Institutions and European Politics, Department of Political Science, University of Zurich.

This book questions whether and to what extent a conjunctural phenomenon such as an economic crisis can bring about lasting political consequences. It focuses on the parties and party systems of four South European countries (Portugal, Spain, Italy, and Greece) between 2008-15. The authors also consider how elections, protests, and interests are affected by the crisis in these four democracies, before assessing how to define the impact of the economic crisis on political participation and competition. In this vein the book analyzes relevant aspects of party systems, the notion of neo-populism as a key to understanding new actors of South European policy, and interest intermediation as a factor of weakness in managing the crisis. Finally, the authors summarize the empirical results emerging from the research: the partial reshaping of cleavages as well as the relevance of the establishment vs. anti-establishment cleavage for the emergence and success of neo-populist parties. The book will be of use to students and scholars interested in South European politics, comparative politics, and democracies.

This is an analysis of the changing pressures and demands placed on party systems in 11 countries in Western Europe since 1945. This book includes studies of the party system in Britain, France, Italy and Germany, as well as studies of Spain, Portugal, Ireland, Sweden, Austria, Belgium and the Netherlands. Five major themes are examined in each chapter. First, the broad development of the party system is accompanied by a discussion of how different party system typologies have been applied to each country. Secondly, a detailed discussion of the historical background to party system developments is provided, dealing with the main divisions derived from the typology of Lipset and Rokkan. Thirdly, the most important contextual variables are considered in terms of the "electoral environment" within which the party system operates. Next, consideration is given to the degree of "unfreezing" of the party system since 1945 and the changing balance between stability and change. Finally, major questions of change and adaptation are examined, updating the text.

This study presents comparative analyses of the process of party governance, from formation and duration to performance. It compares both the developments in the Eastern and Western part of Europe and uses different types of methods and data are used for comparative analysis.
