Schama's last programme is a meditation on the place of the past in Britain's 20th-century history. Personified in the sharply different reactions of two of its greatest figures, Winston Churchill and George Orwell, the programme explores the fate of the country through two world wars, the slump and a nervous postwar peace. What was the impact of the crusades and the protests of the century, and did Winston Smith, hero of Orwell's 1984, foresee the contemporary political landscape?
