The special issue contributes to the exploration of transversal solidarities counterpoised to an exhausted neoliberalism on the one hand and a xenophobic populism on the other. It tracks contours of a multifarious countermovement, traversing ‘race’, class and gender, driven by reimaginings of the common and the renewal of democracy. The emphasis is on the understanding of contending urban justice movements, welcoming communities and their liaisons in a multiscale (local, national, transnational) perspective. A collection of theoretically informed papers discusses cases from urban contexts of Europe and the United States, all riveted by schisms of class, ‘race’/ethnicity and gender, occupied by the ‘migration’ issue and challenged by contending movements for social cum environmental sustainability. Exploring examples of social movements and forms of mobilisation in different contexts, the overarching aim is to retrieve options for transversal solidarities transcending identities while focusing on commonalities.

该特刊有助于探索横向团结，一方面与疲惫的新自由主义和另一方面排外的民粹主义背道而驰。它通过重新构想共同和民主的更新来追踪各种对抗运动的轮廓，穿越“种族”，阶级和性别。重点是从多角度（本地，国家，跨国）的角度理解竞争的城市正义运动，欢迎社区及其联系。一系列具有理论知识的论文讨论了欧洲和美国城市环境下的案例，这些案例都受到阶级分化，“种族” /民族和性别的困扰，被“移民”问题占据，并受到社会和环境可持续发展运动的挑战。
