This chapter explores group identification and social movements among populations of immigrant background in the UK as informed by the structural and cultural framework presiding over their settlement.1 Post-World War II Britain provides the empirical field for our study of labor migrants and refugee social movements. We shall delineate the formulation of three major paradigms over this period and also unpack their components and their genesis in the light of the approach discussed above. It will become apparent that the interaction between international, national, and local parameters led to changing social movements among migrants. Moreover, the interconnections between their experiences in the country of origin and the country of reception both play a part in the formulation of their mobilization.
