Two distinguished historians of twentieth-century Britain, especially Wales, marshal seventeen fellow historians to describe the momentous twentieth century in the history of south-east Wales. The book is the fifth and last volume in a magisterial survey of Gwent/Monmouthshire from prehistoric times to the present day. Two World Wars and deep depression tested the resilience of the county's people, while the decline of mining and heavy industry shifted the balance of the county's economy. Other chapters analyse the life and leisure of ordinary people, their cultural, intellectual and sporting interests, their religion which formerly bulked so large in their lives, and the changes in the landscape of town and country.
