Contributor(s): Dominic Sandbrook | In the mid-1970s, Britain's fortunes seemed to have reached their lowest point since the Blitz. Across the country, a profound argument about the future of the nation was being played out, not just in the political arena but in everything from episodes of Doctor Who to singles by the Clash. As Dominic Sandbrook reveals, this extraordinary, chaotic period was the decisive point in the creation of modern Britain. Dominic Sandbrook is the author of three highly acclaimed books on post-war Britain, as well as a prolific reviewer and columnist. His major new BBC2 documentary series, The Seventies, will air in April 2012 and his latest book is Seasons in the Sun: The Battle for Britain, 1974-1979 published by Allen Lane in May.
