Incubating Revolution: How Social Networks and the Built Environment Sustain Mobilization

How do challengers sustain mobilization under conditions of extreme repression? Social networks and the built environment are critical, interacting at two time scales. Settlement, chain migration, and everyday cooperation produce dense relational environments that shape motivations and constitute latent resources. When contention erupts, those dense social networks can be repurposed to sustain high-risk collective action, providing shelter, escape routes, information, and support. But their efficacy is limited without the organic built environment in which they form; its proximity, limited visibility, and constrained access amplify the effect of dense social ties in facilitating challenge under threat. We substantiate these claims using disaggregated data on protest in Damascus during the 2011 Syrian uprising, finding that neighbourhoods with both dense networks and organic built form exhibit significantly more frequent and confrontational mobilization. By analytically separating the social from the spatial, this article illuminates the mechanisms through which urban neighbourhoods become incubators of rebellion.
