Rather than weakening the forces of nationalism among member states, the expanding power of the European Union actually fosters conditions favorable to regionalist movements within traditional nation-states. Using a cross-national, quantitative study of the advent of regionalist political parties and their success in national parliamentary elections since the 1960s, along with a detailed case study of the fortunes of the pro-independence Scottish National Party, Seth K. Jolly demonstrates that supranational integration and subnational fragmentation are not merely coincidental but related in a theoretical and predictable way.
At the core of his argument, Jolly posits the Viability Theory: the theory that the EU makes smaller states more viable and more politically attractive by diminishing the relative economic and political advantages of larger-sized states. European integration allows regionalist groups to make credible claims that they do not need the state to survive because their regions are part of the EU, which provides access to markets, financial institutions, foreign policy, and other benefits. Ultimately, Jolly emphasizes, scholars and policy-makers must recognize that the benefits of European integration come with the challenge of increased regionalist mobilization that has the potential to reshape the national boundaries of Europe.

“In this careful, persuasive study, Seth Jolly argues that the existence of the EU increases the viability of small states in Europe, thus leading to an increase in the incidence and electoral success of parties demanding greater regional autonomy and independence. This is an attractive and intuitive argument that has been overlooked by previous accounts of regionalist party fortune.”

“Jolly has offered a valuable addition to the literature. He adds considerable value to the study of European political party systems. His ideas and empirical analysis will need to be considered for anyone coming to terms with European integration and its effects on political parties and voters.”

“An imporant and substantial contribution to our understanding of party and electoral politics, in general and in the context of the European Union’s system of multilevel governance . . . this book stands out in its focus on regionalist parties in Europe.”
