This new study considers the impact of the empire upon modern British political culture. The economic and cultural legacy of empire have received a great deal of attention, but historians have neglected the effects of empire upon the domestic British political scene. Dr Thompson explores economic, demographic, intellectual and military influences and he shows how parliamentary and party opinion interacted with imperial ideas and interests in the country at large. This is a major new book which explores the ideology of key imperial campaigns, and their popular support. It makes a critical contribution to recent debates -- about the importance of empire to the nature and development of British national identities before and after the First World War.
