This article analyses the development of municipal immigrant policies in Denmark in the 1970s through a case study of two municipalities, Copenhagen and Ishøj. The two municipalities encountered immigration in the earliest phase of Danish integration policy. In this period, national policies were limited and immigrants integration was primarily a municipal responsibility. As a result, the two municipalities had the opportunity and obligation to develop their own local solutions to the problems caused by migration during this period. The cases illustrate two trajectories in municipal policy-making. Copenhagen followed the national tendency to include guest workers and immigrants in the existing administrative body of the municipality and the welfare system, whereas Ishøj chose a different path with a coherent municipal immigrant policy. Through this case study of city-level policy-making in Denmark, this article contributes to research on municipal policy-making as well as research on the development of immigrant and integration policy.
