Immigration is a main political topic. In Western Europe social conflicts, party systems and political parties have been restructured around an emerging cleavage between integration and demarcation. At the urban level, conflict among immigrant groups and native ones and contention between immigrants and the local authorities are major political dynamics. Main literature has explained why do we observe clashes between immigrants and natives in some locations, but not in others; and what accounts for change in immigrant conflict within locales over time. Not a lot has been written about the outcomes of these conflicts and their impact on citizenship. An emerging literature is measuring important effects in terms of political inclusion, but other effects on civic and social citizenships remain partially unexplored. Empirical researches collected for this special issue stress the dimension of agency of immigrant contentious politics, and show the heuristic value of new approaches in the theory of action, taking into account recognition as well as institutional and normative constraints.
