This is the definitive study of the Irish general election of 2016 - the most dramatic election in a generation, which resulted in the worst electoral outcome for Ireland's established parties, the most fractionalized party system in the history of the state, and the emergence of new parties and groups. These outcomes follow a pattern seen across a number of Western Europe's established democracies in which the 'deep crisis' of the Great Recession has wreaked havoc on party systems. The objective of this book is to assess this most extraordinary of Irish elections both in its Irish and wider cross-national context. With contributions from leading scholars on Irish elections, and using a unique dataset - the Irish National Election Study 2016 - this volume explores voting patterns at Ireland's first post crisis election and it considers the implications for the electoral landscape and politics in Ireland. -- .
