Simultaneously, it subsidized the emigration of Britons to Australia, Canada, and other parts of the Empire, recruited Irish citizens and European refugees to work in Britain, and used regulatory changes to dissuade British subjects of color from coming to the United Kingdom. Paul contends post-war concepts of citizenship were based on a contradiction between the formal definition of who had the right to enter Britain and the informal notion of who was, or could become, really British. extends this analysis to contemporary issues, such as the fierce engagement in the Falklands War and the curtailment of citizenship options for residents of Hong Kong. Paul finds the politics of citizenship in contemporary Britain still haunted by a mixture of imperial, economic, and demographic imperatives.
