This special issue focuses on migrants’ self-organised strategies in relation to housing in Europe, namely the collective squatting of vacant buildings and land. In particular, the contributions to this special issue differentiate between shelter provided in state-run or humanitarian camps and squatted homes. Migrants squats are an essential part of the ‘corridors of solidarity’ that are being created throughout Europe, where grassroots social movements engaged in anti-racist, anarchist and anti-authoritarian politics coalesce with migrants in devising non-institutional responses to the violence of border regimes. In these spaces contentious politics and everyday social reproduction uproot racist and xenophobic regimes. The struggles emerging in these spaces disrupt host-guest relations, which often perpetuate state-imposed hierarchies and humanitarian disciplining technologies. Moreover, the solidarities and collaborations between undocumented and documented activists challenge hitherto prevailing notions of citizenship and social movements, as well as current articulations of the common. These radical spaces enable possibilities for inhabitance beyond, against and within citizenship, which do not only reverse forms of exclusion and repression, but produce ungovernable resources, alliances and subjectivities that prefigure more livable spaces for all. Therefore, these struggles are interpreted here as forms of commoning, as they constitute autonomous socio-political infrastructures and networks of solidarity beyond and against the state and humanitarian provision.
