The booming coal industry of the nineteenth and early twentieth centuries was the main reason behind the creation of modern south Wales and its miners were central to shaping the economics, politics and society of south Wales during the twentieth century. This book explores the history of these miners between 1964 and 1985, covering the concerted run-down of the coal industry under the Wilson government, the growth of miners resistance, and the eventual defeat of the epic strike of 1984-5. Their interactions with the wider trade union movement and society during these years meant the miners were amongst the most important strategically-located sections of the British workforce during this time. The South Wales Miners is the first full-length academic study of the miners and their union in the later twentieth century, in a tumultuous period of crisis and struggle.
