Book excerpt: Although the literature on party politics has significantly advanced both methodologically and theoretically in recent years, the study of political parties in Turkey has been noticeably disconnected and lacking from such conversations. This book evaluates well-established theories and trends in existing party politics literature and relates them to the case of Turkey. It explores fundamental questions such as: Who controls party organizations and how does the locus of control change over time? What kinds of power struggles are observed inside a party and between whom? What do the present and past records of party membership imply for party organizations? What role do grassroots activists play in local and national politics? How do the ideological orientations of party members differ from party leaders and other voters? What types of social cleavages shape political parties and how do they change over time? What constitutes the relationship between the state and parties today? Who finances political parties and what does this imply about the quality of democracy? How and why do party systems change? The various chapters show that party politics in the Turkish context is significantly different to Western and new democracies. By highlighting the significant contribution the Turkish case can make to existing conceptual frameworks and theories, this book will be a valuable resource for anyone studying political parties, party systems and comparative politics, as well as Turkish politics.
