This book combines radical history, critical geography, and political theory in an innovative history of the solidarity campaign in London during the 1984-5 miners’ strike. Thousands of people collected food and money, joined picket lines and demonstrations, organised meetings, travelled to mining areas, and hosted coalfield activists in their homes during the strike. The support campaign encompassed longstanding elements of the British labour movement as well as autonomously organised Black, lesbian and gay, and feminist support groups. This book shows how the solidarity of 1984-5 was rooted in the development of mutual relationships of support between the coalfields and the capital since the late 1960s. It argues that a culture of solidarity was developed through industrial and political struggles that brought together diverse activists from mining communities and London. The book also takes the story forward, exploring the aftermath of the miners’ strike and the complex legacies of the support movement up to the present day. This rich history provides a compelling example of how solidarity can cross geographical and social boundaries. This book is essential reading for students, scholars, and activists with an interest in left-wing politics and history.
