Party politics has been undergoing a revival in many democracies. However, parties are much less studied in countries with unstable political regimes. Party interactions can help to provide explanations for the emergence and performance of regimes, whether of the democratic or authoritarian type. This book is a comprehensive case study that analyses, in depth, Turkish political parties. Starting with broad historical analysis, Huri Türsan takes the reader down to the most recent electoral activities and party politics in a country whose topicality is on the rise, not least due to its political problems. While the author deals with many issues of politics (including the role of the military), she focuses on an aspect of party competition which renders democracy problematic in Turkey, namely polarisation in party politics along cleavages.
