Causes

According to a 2017 review study of civil war research, there are three prominent explanations for civil war: greed-based explanations which center on individuals' desire to maximize their profits, grievance-based explanations which center on conflict as a response to socioeconomic or political injustice, and opportunity-based explanations which center on factors that make it easier to engage in violent mobilization. According to the study, the most influential explanation for civil war onset is the opportunity-based explanation by James Fearon and David Laitin in their 2003 American Political Science Review article.
