This paper accounts for important shifts in the debate on immigration reform by considering the geographies of protest. Our findings point to the importance of urban hubs of activists and organisations that have worked with one another over extended periods of time. While these urban hubs constitute distinctive activist worlds, they have also connected to one another and coordinated nation-wide actions through a variety of networks (social media, interpersonal, and inter-organisational). Using interviews, network analysis, and data on funding, we show how this decentralised network evolved and eventually outflanked nationally centred and reformist advocacy organisations in recent anti-deportation campaigns.

This article examines engagement with digitally networked, politically contentious actions. Maintaining engagement over time is a key challenge for social movements attempting to network digitally. This article argues that proximity serves as a condition to address this challenge, because it configures the personal networks upon which transmission depends. This is a paradox of digital activism: it has the capacity to transcend barriers; however, proximity is essential for sustaining relations over time. Examining Twitter data from the #not1more protest campaign against immigrant deportations in the United States, quantitative and social network analyses show a differentiated development of engagement, which results in a particular geographical configuration with the following attributes. First, there is a robust and connected backbone of core organizers and activists located in particular major cities. Second, local groups engage with the campaign with direct actions in other cities. Third, a large and transitory contingent of geographically dispersed users direct attention to the campaign. We conclude by elaborating how this geographically differentiated configuration helps to sustain engagement with digitally networked action.

The Movement for Black Lives has connected millions of people online. How are their outrage and hope mediated through social media? To address this question, this article extends Randall Collins’s Interaction Ritual Theory to social media. Employing semisupervised image recognition methods on a million Instagram posts with the hashtag #blacklivesmatter, we identify four different interaction ritual types, each with distinct geographies. Instagram posts featuring interactions with physical copresence are concentrated in urban areas. We identify two different types of such areas: arenas where contention plays out and milieus where movement identities are affirmed. Instagram posts that do not feature physical copresence are more geographically dispersed. These posts, including memes and selfies, allow people to engage with the movement even when they are not embedded in activist environments. Our analysis helps to understand how different forms of engagement are embedded in particular places and connected through the circulation of social media posts.

The immigrant rights movement in the United States evolved from largely localised and grassroots struggles in the 1990s into a coherent and coordinated national social movement in the late 2000s and 2010s. Scaling up in this way is challenging because grassroots organisations tend to lack the resources needed to operate at the national level over an extended period. This paper examines how this movement overcame the obstacle by focusing on role of national organisations in concentrating key resources (money, political capital, discursive power) and developing a national social movement infrastructure. The consequences of this process are shown to be paradoxical: While it enabled potent advocacy in the national political arena, the concentration of resources generated constraints on strategies and tactics, inequalities, and conflicts between different factions of the movement. This article describes the process by drawing on interviews with key stakeholders, tax files, newspapers, foundation documents, and White House visitor records.

Undocumented immigrant youths, known as the Dreamers, rose to exceptional prominence in the American immigrant rights movement in the 2000s and 2010s. The Dreamers had considerable success in presenting themselves as assimilated and hard-working patriots worthy of regularization. While this strategy worked well in the media and politics, it also created a distance between the Dreamers and less privileged groups of undocumented immigrants. In 2013, just when they were widely recognized as legitimate, the Dreamers made the remarkable move to change their strategy: rather than presenting themselves as model immigrants uniquely worthy of regularization, they began mobilizing for policies benefiting all undocumented migrants. By documenting and explaining this change in strategy, this paper addresses the broader question of what separates and binds privileged and underprivileged subgroups in social movements.
