“…At the crossroads of our respective roots in political sociology and social geography, this contribution, written four hands, argues that geography matters to study social movements (Tilly, 2000;Sewell, 2001;Martin & Miller, 2003;Ripoll, 2005a;Miller et al, 2013;Pailloux & Ripoll, 2019) and thus first considers space as a structuring framework within which any of them can, or cannot, emerge and unfold. This perspective is in line with the concepts of 'space organisation' (Tilly, 2000), 'context' (Martin & Miller, 2003;Pailloux & Ripoll, 2019), or 'configuration' (Auyero, 2005;Laferté, 2014;Combes et al, 2016). Indeed, space contributes to explaining, thanks to its features, but also thanks to the distribution of the social groups present, or to the uses and privileges that are instituted there, why a social movement occurs.…”
