Replication Data for: From Social Networks to Political Parties: Indigenous Party-Building in Bolivia

While existing scholarship recognizes the centrality of social organizations for party-building efforts, how network structures condition party-building remains underexamined. This article argues that a core property of the network environments within which proto-parties emerge—structural resilience—shapes opportunities for proto-parties’ expansion and consolidation. More resilient network structures—those with multiple pathways available for expansion—decrease proto-parties’ vulnerability to structural threats and allow them to circumvent competition. To evaluate this theory, I examine the organizational networks of three comparable indigenous party-building efforts in Bolivia. Using original network data and a mixed-methods approach, I demonstrate that MAS-IPSP succeeded in establishing itself as the indigenous party because of the structural resilience of the network environment within which it originated. By contrast, its counterparts failed when targeted network attacks undermined their access to organizational spaces critical to their expansion strategies. The findings reveal often-overlooked variation in the relationship between social organizations and political parties.
