After the First World War, Britain faced a number of challenges as it sought to adapt to domestic conditions of mass democracy while maintaining its position in the empire in the face of national independence movements. As politicians at home and abroad sought to legitimize their position, new efforts were made to conceptualize nationality and citizenship, with attempts to engage the public using mass media and greater emphasis on governing in the public interest. Brave New World reappraises the domestic and imperial history of Britain in the inter-war period, investigating how 'nation building' was given renewed impetus by the upheavals of the First World War. The essays in this collection address how new technologies and approaches to governance were used to forge new national identities both at home and in the empire, covering a wide range of issues from the representation of empire on film to the convergence of politics and 'star culture'. The book is an invaluable resource for scholars of British social, political and imperial history, as well as being of interest to the general reader.
