Introduction
Lewis Coser (1913–2003) stands as one of the most influential sociologists of the 20th century who reinterpreted the role of social conflict in modern societies. His work, “The Functions of Social Conflict” (1956), presented a strikingly different view from traditional sociological thinkers who saw conflict as a sign of social breakdown or instability. Coser, drawing from both Karl Marx and Georg Simmel, proposed that conflict is not always destructive; rather, it can serve as a functional and stabilizing force in society. His theoretical approach redefined the understanding of social order by suggesting that conflict, under certain conditions, can promote adaptation, cohesion, and change.
This article explores Lewis Coser’s views on conflict theory, its sociological foundations, major concepts, and its significance for understanding modern societies.

1. Background and Theoretical Influences
Lewis Coser’s conflict theory emerged as a synthesis of earlier sociological traditions. He was particularly influenced by Georg Simmel’s idea that conflict is a normal and necessary part of social life and by Karl Marx’s emphasis on the structural roots of conflict. However, unlike Marx, who viewed conflict as the driver of revolutionary change and class struggle, Coser emphasized the functional and integrative aspects of conflict.
Lewis Coser’s theory developed during the post–World War II period when structural functionalism, represented by Talcott Parsons, dominated sociology. Functionalists emphasized harmony, stability, and consensus as the basis of society. Lewis Coser challenged this one-sided view by integrating conflict into the functionalist framework, arguing that conflict can serve essential functions in maintaining and transforming societies.
2. Conflict as a Functional Element in Society
Lewis Coser’s central argument is that conflict is not inherently pathological or destructive; instead, it performs positive functions that can strengthen social relations and institutions.
He proposed that conflict serves several functions:
- Preservation of Group Boundaries:
Conflict with external groups strengthens internal solidarity. When a group faces an external threat, its members tend to unite, setting aside internal differences. For instance, during national crises or wars, internal divisions often diminish as people come together against a common enemy. - Adaptation and Change:
Conflict exposes tensions and contradictions within a social structure, pushing it to adapt and change. By surfacing suppressed issues, conflict prevents the accumulation of unresolved tensions that could otherwise lead to violent upheaval. - Maintenance of Social Balance:
Through controlled and institutionalized forms of conflict—like democratic debate, strikes, or elections—societies maintain balance and allow for grievances to be addressed constructively. This prevents explosive conflict and promotes gradual reform. - Clarification of Values:
Conflict can help define and clarify group values, norms, and goals. When challenged, a group reaffirms what it stands for, strengthening its moral and cultural foundation.
In short, Lewis Coser viewed conflict as a mechanism for adjustment and renewal, not simply as a force of disorganization.
3. Types and Dynamics of Social Conflict
Lewis Coser differentiated between realistic and non-realistic conflicts, a distinction he borrowed from Simmel but expanded in his analysis.
- Realistic Conflict:
These conflicts arise from actual, objective differences in interests or resources. For example, disputes between labor and management over wages and working conditions are realistic conflicts. They are instrumental and can often be resolved through negotiation or compromise. - Non-Realistic Conflict:
These conflicts are expressions of tension, frustration, or hostility with no direct relation to tangible goals. They serve as outlets for emotional release. For example, racial hatred or scapegoating might not have a rational basis but help individuals vent frustrations.
Lewis Coser argued that realistic conflicts are more functional for society because they can lead to institutional change or policy reforms, whereas non-realistic conflicts, though less productive, may still release built-up emotional energy and thus help maintain stability.
4. Conflict Within and Between Groups

Lewis Coser examined how conflict operates both within groups (intragroup conflict) and between groups (intergroup conflict).
- Intragroup Conflict:
Within a group, conflict can either strengthen or weaken unity depending on the group’s level of cohesion. In highly cohesive groups, internal conflict can promote innovation and flexibility. In loosely organized groups, however, it may lead to fragmentation. For example, political parties often experience internal ideological conflicts. When managed constructively, these disagreements help the party evolve and remain relevant; when poorly managed, they can cause splits or decline. - Intergroup Conflict:
Conflict between groups can reinforce internal solidarity. When a group confronts an external threat—such as a rival organization, competing nation, or social movement—it tends to become more cohesive. Coser called this the “external conflict-solidarity” effect.
Through these analyses, Lewis Coser demonstrated that conflict has a dual nature—it can integrate or disintegrate, depending on the context and the strength of existing social bonds.
5. Institutionalization of Conflict
One of Lewis Coser’s major contributions is his emphasis on the institutionalization of conflict. In modern societies, mechanisms exist to channel and regulate conflict, preventing it from becoming destructive.
For example, parliaments, labor unions, legal systems, and democratic elections are institutional arrangements that allow for the peaceful expression and resolution of conflicts. Coser believed that societies capable of institutionalizing conflict are more stable and adaptable because they can manage tensions without resorting to violence.
In contrast, authoritarian societies that suppress dissent tend to accumulate hidden tensions. When these tensions finally erupt, they can take violent and revolutionary forms. Thus, Coser’s theory implies that the openness of a society to conflict determines its resilience and longevity.
6. Coser’s Critique of Structural Functionalism
Lewis Coser’s conflict theory can be viewed as a corrective to structural functionalism. Functionalists like Parsons and Merton focused on how social institutions maintain order and consensus. Coser argued that this view ignored the role of tension, competition, and change.
He asserted that a truly functional analysis of society must include both consensus and conflict, as they are interdependent processes. Conflict contributes to integration by renewing social bonds and redefining values, while consensus provides the stability necessary for conflict to remain manageable.
Thus, Lewis Coser presented a dynamic model of society, where stability and change, harmony and tension, coexist and complement each other.
7. Relevance of Coser’s Theory in Contemporary Society
Lewis Coser’s conflict theory remains profoundly relevant in analyzing modern social issues. In today’s world—characterized by political polarization, social movements, labor struggles, and identity conflicts—Coser’s insights help explain why conflict is inevitable and often beneficial.
For example:
- Social Movements: Civil rights movements, environmental activism, and feminist struggles often create tension but ultimately contribute to greater equality and justice.
- Democratic Politics: Political opposition and protest are vital to democratic functioning; they expose flaws and push for accountability.
- Globalization: Conflicts between local cultures and global economic forces stimulate adaptation and cultural negotiation.
Lewis Coser’s framework encourages societies to embrace conflict as a sign of vitality, rather than fear it as a threat to order.
8. Criticisms of Coser’s Conflict Theory

While influential, Coser’s theory has faced some criticisms:
- Critics argue that he underestimates the destructive potential of conflict, particularly in deeply divided or authoritarian societies.
- Marxist scholars claim that Coser’s theory is too moderate, as it downplays structural inequalities and power dynamics.
- Others note that Coser focuses more on group-level interactions than on macro-structural forces like capitalism or state power.
Nevertheless, his emphasis on the positive and adaptive aspects of conflict remains a cornerstone in sociological thought.
Conclusion
Lewis A. Coser revolutionized sociological thinking by demonstrating that conflict is not merely a symptom of social disintegration but an essential component of social life. By integrating conflict into functionalist analysis, he provided a balanced and realistic understanding of society as a dynamic system shaped by both consensus and dissent.
Coser’s theory teaches that conflict, when institutionalized and managed, can renew social structures, strengthen solidarity, and promote change. In a world marked by constant social, economic, and political tensions, his perspective offers a framework for understanding how societies evolve—not despite conflict, but through it.
