Rebel Ideology Predicts Who Rewrites Postwar Constitutions

Why Rebel Ideology Shapes Constitutions After Civil War?

Simon Ballesteros, Laia Balcells, and Daniel Solomon ask how formal institutions—above all constitutions—emerge and change after civil wars. They argue that beyond distributional bargaining or peace-keeping motives, the ideological goals of armed groups powerfully shape whether and how countries rewrite their basic law after conflict. This matters for understanding how post-war societies institutionalize winners' visions of order and rights.

Statistical Analysis of 153 Civil Wars (1944–2016)

The authors combine a cross-national quantitative design with a comparative case study. Using a dataset of 153 civil wars from 1944–2016, they classify actors by ideology (including revolutionary socialist and secessionist rebels) and by post-war victory status, then link these classifications to constitutional outcomes. Outcomes distinguish between the promulgation of entirely new constitutions and the adoption of amendments, and the authors evaluate constitutional content for symbolic elements and rights protections. A focused comparative analysis of multiple constitutional transitions in Cambodia illustrates the mechanisms at work.

Key Findings

• Victorious revolutionary socialist (RS) rebels and victorious secessionist rebels are more likely to promulgate entirely new constitutions after war.
• Victorious incumbents are more likely to pursue constitutional change through amendments rather than full replacement.
• Constitutions enacted by non‑Maoist RS rebels tend to contain more symbolic content and stronger rights provisions than those adopted by incumbents or other victorious rebel types.

Case Study: Cambodia

The Cambodia comparison is used to show how ideological commitments and post-war power dynamics translate into distinct constitutional choices across multiple transitions, illustrating the causal pathways the statistical analysis uncovers.

Implications for Scholarship and Policy

The results highlight ideology as a central explanatory factor in post-conflict institutional design: armed groups with transformative social projects leave durable imprints on constitutional form and content. The findings suggest scholars and policymakers should pay closer attention to rebel goals—beyond simple victory or bargaining leverage—when predicting and shaping post-war constitutional outcomes.
