Cross-Cuttingness, Cleavage Structures and Civil War Onset

In: British journal of political science, Band 41, Heft 1, S. 111-138

Abstract

This article seeks to further our understanding of how social structure affects the onset of civil war. Existing studies to date have been inconclusive, focusing only on single-cleavage characteristics of social structure, such as ethnic or religious fractionalization. This study argues that models that do not take into account the relationship between cleavages (or cleavage structure) are biased and thus reach faulty conclusions. With the focus on the cleavages of ethnicity and religion, the effects of two characteristics of cleavage structure on civil war onset (cross-cuttingness and cross-fragmentation) are defined and tested. A new index of ethno-religious cross-cuttingness (ERC), derived from national public opinion surveys, reveals that ERC is a significant determinant of civil war onset when interacted with ethnic fractionalization.
