Margaret Thatcher was one of the most controversial figures of modern times. Her governments inspired hatred and veneration in equal measure, and her legacy remains fiercely contested. Yet assessments of the Thatcher era are often divorced from any larger historical perspective. This book draws together leading historians to locate Thatcher and Thatcherism within the political, social, cultural and economic history of modern Britain. It explores the social and economic crises of the 1970s; Britain's relationships with Europe, the Commonwealth and the United States; and the different experiences of Thatcherism in Scotland, Wales and Northern Ireland. The book assesses the impact of the Thatcher era on class and gender, and situates Thatcherism within the Cold War, the end of Empire and the rise of an Anglo-American 'New Right'. Drawing on the latest available sources, it opens a wide-ranging debate about the Thatcher era and its place in modern British history.
