'This inspiring collection of excellent essays meticulously documents how people across European cities are creating solidaristic, democratic and radical forms of citizenship as counter-movements to nationalism and authoritarianism. Empirically focusing on mid-size cities (e.g., Aalborg, Bern, Hamburg, Ljubljana and Palermo), it shows how these movements make everyday life political through mutual aid and care, horizontal and participatory organising, and alliances across diverse rights to the city, such as work, housing, health, migration and asylum. Theoretically, it demonstrates that building infrastructures of solidarity, generating affective bonds, and developing translocal connections create strong democratic communities.'
