Political parties regularly change and adapt in response to ever-changing circumstances. Until now these changes have frequently prompted both scholars and the media to suggest a whole new type of political party, and over time the number of models and types has proliferated to the point of confusion, contradiction, and a loss of explanatory power. In this sophisticated yet accessible study, André Krouwel rejects this mélange of models as inadequate. He utilizes a wide range of data sources to analyze the ideological, organizational, and electoral change undergone by more than one hundred European parties in fifteen different countries, from Scandinavia to the Iberian Peninsula, between 1945 and 2010. The result is one of the most comprehensive empirically grounded studies to date of the genesis, development, and transformation of political parties in advanced democratic states.

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.

With a focus on 'Europe 31', understood as the EU28 plus Switzerland, Norway, and Iceland, the book brings together separate strands of literature which often remain disconnected in political science narratives. Looking at citizen-state relations, the restructuring of politics and institutions of the state, and developments which reach 'beyond and below' the state, it interrogates a variety of issues ranging from the decline of parties or the re-emergence of nationalism as a political force, to liberal challenges to social democracy, terrorist threats, and climate change.

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.

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 provides an in-depth analysis of the ‘technocratic shift’ in ministerial recruitment, measuring its extent and variations over time in fourteen European countries. It addresses the question: who governs in European democratic regimes? Just a few decades ago, the answer would have been straightforward: party-men and (fewer) party-women. More recently, however, and in varying degrees across Europe, a greater proportion of non-politicians or experts have been recruited to government, as exemplified by the 2017 election of Emmanuel Macron to the French Presidency. These experts, frequently labelled “technocrats”, increasingly occupy key executive positions and have emerged as powerful actors in the decision-making process. This edited collection explores the contemporary debates surrounding the relationship between technocracy, democracy and political leadership, and will appeal to scholars and advanced students interested in these fields.

This book analyses the Christian Democratic Union of Germany (CDU), one of Europe’s most successful and influential political parties. The CDU might have been expected to struggle in the circumstances of a more diverse, secular reunified Germany, yet it has prospered to an extent almost unparalleled in western Europe. Chapters consider the CDU’s policies (the factors driving them, their variation across Germany, the relationship to women, and the welfare state), its organisational development and change, and its position within the party system. Contributors particularly emphasise the diversity of the CDU, and the way it varies across Germany’s regions. The CDU is compared to other Christian Democratic parties, and special consideration is given to the CDU’s Bavarian sister party, the Christian Social Union (CSU). This book was published as a special issue of German Politics.
