Book excerpt: The first comprehensive study in English of the earliest and largest 'Third-World' migration into pre-war Europe. Full attention is given to the relationship between the society of emigration, undermined by colonialism, and processes of ethnic organisation in the metropolitan context. Contemporary anti-Algerian racism is shown to have deep roots in moves by colonial elites to control and police the migrants and to segregate them from contact with Communism, nationalist movements and the French working class.
