This paper is an introductory survey of the evolution of multiculturalism in Britain and Germany over the past two centuries. The historical approach argues that the main determinants of difference between these nation states lie in their long-term traditional attitudes towards immigrants and ethnic minorities. It focuses upon the patterns of immigration into Britain and Germany as well as the differing imperial traditions, which have both left differing legacies. An equally important historical factor has been the legal position of aliens in the two states, in which, until very recently, Britain adopted a policy of "jus solis", whereas Germany pursued one of "jus sanguinis". The paper then examines the realities of multiculturalism in the two states. Due primarily to the historical traditions of nationality legislation, immigrants and their descendants in Britain have come to play a more important role in recent British history than their contemporaries in Germany, particularly if we examine their role in the political process and in popular culture. While the conclusion reiterates the differences, it also stresses that we should not view Britain and Germany as the opposite ends of the multicultural spectrum, as both are modern liberal democracies with significant ethnic minority populations.
