Democracy thrives on vigorous competition between political parties. However, in several established democracies one party manages to dominate national politics for decades at a time, seemingly creating a democratic one-party unnatural democracy. This book examines five such countries - Canada, Ireland, India, Japan, Italy - to understand what kind of party comes to dominate democratic competition, and how and why they do so. In different countries with different political challenges, an analysis of their 'Government Parties' reveals their common relationship with the origins and operations of the states they dominate, and the nation- and/or state-building challenges they face. Democratic dominance cannot last forever; how a government party responds to the seemingly inevitable decline of long-term support defines the prospects for its unnatural democracy.
