Is it greed or grievance that fuels the fires of civil war?
While we often imagine civil wars as clashes of identity or religion, economic opportunity might be the true driver. New research suggests that the decision to rebel is often less about deep-seated hatreds and more about the calculated cost of forgoing a steady paycheck.
For decades, scholars have debated whether civil wars are driven by 'grievance'—clashes over ethnicity, religion, or political injustice—or 'greed,' where individuals seek to maximize profit. A 2017 review of research suggests that the most influential explanation for the onset of conflict is actually 'opportunity-based.' This theory, championed by James Fearon and David Laitin, posits that rebellions occur when the structural conditions make it easier to mobilize and sustain an insurgency.
A landmark study by the World Bank, known as the Collier–Hoeffler Model, analyzed 78 five-year increments of conflict between 1960 and 1999. The findings suggest that economic factors are more predictive than identity. For instance, a high dependence on primary commodity exports, such as oil or gold, significantly increases risk because these resources are easier to capture than manufacturing sectors. Conversely, higher male secondary school enrollment and economic growth act as stabilizers; when young men have more to lose in terms of future earnings, they are less likely to join a rebellion.
However, the debate remains far from settled. Critics like David Keen argue that reducing complex human suffering to simple quantitative motives is reductive. Others, such as Lars-Erik Cederman, suggest that while ethnic diversity itself might not trigger war, the way ethnic groups hold power and access resources is crucial. Ultimately, the consensus is shifting away from a simple binary toward a more nuanced understanding of how state weakness, resource wealth, and the cost of opportunity intersect to ignite large-scale internal conflict.
