In the wake of the Scottish vote on independence, questions of sovereignty, devolution, and local control have perhaps never been more salient. This book explores the evolution of the idea of national identity in modern Britain as it affected Wales. It ranges historically from the French Revolution and its aftershocks to the wide-ranging effects of World War I and on to present debates over decentralization and ties with Europe, while also offering close looks at key personalities, like Lloyd George, the first (and thus far only) Welsh prime minister. Drawing on both his extensive experience in politics and his decades of academic study, Kenneth O. Morgan has written what is likely to be the definitive work on this topic.
