Book cover

When Rebels Win (Cornell University Press, 2025) examines what rebels do with the state if they are able to gain control of it. Many assume civil wars destroy state capacity. In the Democratic Republic of Congo and Libya, for instance, victorious rebels perpetuated state weaknesses. Yet elsewhere, like in China and Rwanda, they built strong, capable states. 

Kai M. Thaler argues that to explain varying post-victory governance we must look at rebel group ideologies: the ideas and goals around which a group is formed. Where a group's ideology falls along two key dimensions—programmatic versus opportunistic, inclusive versus exclusive—influences how it governs. Programmatic-inclusive groups seek to reach across territory and work with populations to implement goals, building the state to try to transform society. Opportunistic-exclusive groups, by contrast, prioritize personalized power and private wealth, neglecting statebuilding.

With rich evidence from Africa, Latin America, and Asia, When Rebels Win rethinks accounts of rebel behavior and post-war governance emphasizing factors such as resource availability or international intervention. Wartime rebel ideology, Thaler demonstrates, is not just "cheap talk"—and civil war can, counterintuitively, lead to stronger states.

This episode of UC IGCC Talking Policy Podcast was recorded on January 29, 2026. Since 1945, nearly a quarter of civil wars have ended in victory for rebel groups. The stories of how these groups function and fare after their succession of power, however, are complex and varied. In this episode of Talking Policy, host Lindsay Shingler sits down with political scientist Kai Thaler of UC Santa Barbara to discuss his new book, When Rebels Win: Ideology, Statebuilding, and Power After Civil Wars. Together, they explore why civil wars have replaced interstate wars as the most prevalent form of armed conflict since World War II, and what these types of struggles for power ultimately mean for their regions and the world when rebels are successful in their attempt to gain control of the state.
