This book explores the crisis of the British state. Though it has been particularly apparent since the outcome of both the 2014 Scottish independence and 2016 'Brexit' referendums, it stems from deep historical roots. The book traces the origins of the state to the original Act of Union of 1707 and demonstrates how different notions of British destiny - Protestant, imperial, social democratic - have held the state together at different times. The present crisis, it is argued, is due to the exhaustion of these senses of destiny. Moran shows how the United Kingdom is now held together as a militarised state prone to disastrous adventures like the invasion of Iraq, and concludes by examining some alternative futures for the state. This book will appeal to students, scholars and the general reader interested in British politics and political history.
