This book examines the new anti-establishment parties electorally succeeding at the expense of their established counterparts and argues that party organization matters for their electoral success.

It explores a relationship between these parties' electoral success and their party organization. Using a framework to explain the role of organizational features such as local party branches, party membership, and party elites in this process, it reveals how they help parties to be more stable, cohesive, and legitimate; a state that facilitates better conditions for electoral success. It also shows that control over party organization is achieved partially by the existence of a corporate network associated with party leaders' businesses.

This book will be of key interest to scholars and students of party politics and political parties, anti-establishment politics, and Eastern European politics.
