Institutionalization has become a paramount concept to compare party systems in regions spanned by the third wave of democratization. Based on raw electoral data from 30 sub-Saharan African countries observed between 1966 and 2016, this text explores the causes and mechanisms of Party System Institutionalization (PSI) and its relationship with the processes of mobilization and democratization. Posing key theoretical and empirical questions in cross-regional comparison, it examines and reveals the defining properties of PSI, how they should be measured and under what conditions it varies. In doing so, it contributes with a new explanatory framework of party system development – that gives primacy to modes of transition, political institutions and party-citizen linkages – to further cross-regional comparisons among third-wave party systems. This text will be of key interest to scholars and students of democratization, elections, and African politics, and more broadly to comparative politics.

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.

In this rich and broad-ranging volume, Giovanni Sartori outlines what is now recognised to be the most comprehensive and authoritative approach to the classification of party systems. He also offers an extensive review of the concept and rationale of the political party, and develops a sharp critique of various spatial models of party competition. This is political science at its best – combining the intelligent use of theory with sophisticated analytic arguments, and grounding all of this on a substantial cross-national empirical base. Parties and Party Systems is one of the classics of postwar political science, and is now established as the foremost work in its field.

New political parties have regularly appeared in developed democracies around the world. In some countries issues focusing on the environment, immigration, economic decline, and regional concerns have been brought to the forefront by new political parties. In other countries these issues have been addressed by established parties, and new issue-driven parties have failed to form. Most current research is unable to explain why under certain circumstances new issues or neglected old ones lead to the formation of new parties. Based on a novel theoretical framework, this study demonstrates the crucial interplay between established parties and possible newcomers to explain the emergence of new political parties. Deriving stable hypotheses from a simple theoretical model, the book proceeds to a study of party formation in twenty-two developed democracies. New or neglected issues still appear as a driving force in explaining the emergence of new parties, but their effect is partially mediated by institutional factors, such as access to the ballot, public support for parties, and the electoral system. The hypotheses in part support existing theoretical work, but in part present new insights. The theoretical model also pinpoints problems of research design that are hardly addressed in the comparative literature on new political parties. These insights from the theoretical model lead to empirical tests that improve on those employed in the literature and allow for a much-enhanced understanding of the formation and the success of new parties.

This collection brings together some of the most significant and influential work by leading comparativist Peter Mair (1951–2011). The selection ranges from considerations on the relevance of concept formation to the study of party systems and party organisations; and from reflections on the democratic legitimacy of the European Union to the future of party democracy. Including frequently cited papers alongside lesser-known work, the writings collected in this volume attest to the broad scope and depth of Mair’s insights into comparative party politics, and the changing realities of party government. As such, they form an important and enduring contribution to the study of politics, and a fitting tribute to an inspirational and much-missed figure in the global political science community. Edited and introduced by Ingrid van Biezen, with an intellectual portrait of Peter Mair by Stefano Bartolini and Hans Daalder.
