State Violence Theory and Types: Understanding Greed, Grievances, and Armed Conflict

Why do some societies erupt into violence while others remain peaceful despite ethnic diversity? Why do armed groups emerge in resource-rich regions? These questions have puzzled conflict scholars for decades. Understanding the roots of state violence and armed conflict requires examining two competing yet complementary theories: whether combatants are motivated by greed or grievances. While these frameworks might seem abstract, they help explain real-world conflicts from the diamond wars in Sierra Leone to ethnic tensions in South Asia.

Understanding greed theory: when resources fuel rebellion 🔗

The greed theory of conflict, most famously developed by economists Paul Collier and Anke Hoeffler, argues that armed conflicts arise primarily from economic motivations rather than genuine political or social grievances. This perspective treats rebellion as an economic activity, where combatants conduct an informal cost-benefit analysis before joining insurgent groups.

According to this framework, conflicts are more likely in states with weak capacity and abundant natural resources. Collier and Hoeffler found that certain natural resources like oil increased conflict onset, while others like diamonds prolonged conflict duration. Why? Natural resources lower the startup costs of war and provide easy financing for prolonged fighting. When resources are concentrated in rural, hard-to-defend areas, rebel groups can more easily control and exploit them.

The theory also highlights how low per capita GDP increases civil war risk. When average incomes are low, earning wages through conflict becomes a more attractive option than peaceful employment. States with negative economic growth face a double burden: limited capacity to provide economic concessions to opposition groups and weak military apparatus to counter armed challenges.

Grievance theory: when identity and deprivation collide 🔗

While the greed model focuses on economic opportunity, grievance theory centers on collective struggles for basic human needs. Scholar Edward Azar developed the concept of protracted social conflict, arguing that civil wars stem from communal groups fighting for security, recognition, fair access to political institutions, and economic participation.

Azar identified that conflicts arise when large portions of the population face denial of fundamental needs. These aren’t just material deprivations but include political exclusion, cultural discrimination, and threats to group identity. When governing elites monopolize power and resources, marginalizing peripheral groups, those excluded populations eventually mobilize violent opposition.

The role of weak state capacity 🔗

Contemporary conflict analysts have found that weak state capacity and denial of human needs are central to understanding modern conflicts. States that cannot provide basic services, ensure security, or offer meaningful political participation create conditions where armed rebellion becomes an appealing alternative. This explains why conflicts in Nepal, Sri Lanka, Indonesia, the Philippines, India, and Pakistan require understanding both political grievances and economic factors.

Identity-based conflict and the ethnic security dilemma 🔗

Ted Gurr’s pioneering work through the Minorities at Risk project identified ethnic and religious competition as focal points of post-Cold War civil wars. His research surveyed over 275 politically active ethnic groups worldwide, revealing patterns about when and why ethnic identities become sources of violent conflict.

Analysis from the Political Instability Task Force found that ethnic wars occur most frequently in countries with specific characteristics: larger populations with medium to high ethnic diversity, partial democracies suffering from political factionalism, nations bordering countries already experiencing civil war, societies with histories of recent ethnic conflict, and countries with large youth populations.

The clash of civilizations debate 🔗

Samuel Huntington took identity-based conflict arguments further, proposing that cultural and religious identities would become the primary source of conflict in the post-Cold War world. His controversial thesis argued that geopolitical fault lines between civilizations would replace ideological divides as sources of global tension.

Huntington stressed perceived threats from countries basing traditions on religious faith, particularly highlighting tensions between Western and Islamic civilizations. However, critics like Edward Said have challenged this framework as based on oversimplified characterizations and potentially reinforcing racist ideology and assumptions of Western supremacy.

Horizontal inequalities: when group differences matter 🔗

Perhaps the most compelling integration of greed and grievance perspectives comes from the concept of horizontal inequalities. Research by Frances Stewart and colleagues at Oxford’s Centre for Research on Inequality, Human Security and Ethnicity demonstrated that economic inequality between distinct identity groups or communities is a powerful predictor of armed conflict.

Unlike vertical inequalities that measure differences between individuals, horizontal inequalities examine disparities across ethnic, religious, or regional groups. When one ethnic group systematically faces lower incomes, fewer educational opportunities, and political exclusion compared to others, these overlapping disadvantages create potent grievances.

Conditions that provoke conflict 🔗

The CRISE research program identified specific conditions when horizontal inequalities are most likely to trigger violence. Conflicts become more probable when inequalities are sustained over long periods, when boundaries between identity groups remain impermeable, when disadvantaged groups are numerically large, when inequalities remain consistent across political, economic, and social dimensions, when aggregate incomes decline, and when governments prove unresponsive to group grievances.

Historical examples illustrate these dynamics powerfully. In Sri Lanka, systematic policies that reversed Tamil educational and employment advantages created new horizontal inequalities favoring the Sinhalese majority. This overcorrection, combined with language policies and political exclusion, fueled decades of civil war. Similarly, consistent economic, social, and political disadvantages faced by Catholics in Northern Ireland contributed to prolonged violent conflict.

Integrating greed and grievance 🔗

Modern conflict scholarship increasingly recognizes that greed and grievance aren’t competing explanations but interacting forces. Economist David Keen argues that greed generates grievances and rebellion, which in turn legitimizes further resource extraction. Elite groups may deliberately manipulate ethnic identities and grievances to justify economic predation.

In conflicts from Southeast Asia to Africa, we see how resource competition intersects with identity-based grievances. Mining exploitation in the Philippines conflicts with indigenous land rights. Violence in Papua, Sulawesi, and Maluku involves struggles over land and resources intensified by environmental degradation. Corrupt governments engage in rent-seeking that enriches elites while alienating marginalized populations who then mobilize armed resistance.

The challenge for policymakers becomes clear: sustainable peace requires addressing both the economic opportunities that make rebellion viable and the underlying grievances that make populations willing to fight. Interventions focused solely on disrupting resource flows or on political reforms will prove insufficient if they don’t tackle the complex interplay between material incentives and collective deprivations.

What do you think? Can conflicts truly be prevented by addressing horizontal inequalities before they explode into violence? In situations where both greed and grievance drive conflict, which should peace-builders prioritize first?
