Johan Galtung’s Conflict Types: Intrasystem and Intersystem Conflicts

Conflict is a constant feature of human life, ranging from a quiet inner debate about a career choice to armed disputes between nations. To make sense of this enormous range, scholars need a framework that organises conflicts by who is involved and at what level. Johan Galtung, the Norwegian sociologist widely regarded as the principal founder of peace and conflict studies, gave us exactly that. His classification sorts conflicts into four basic types and adds a crucial distinction between disputes that occur within a single system and those that erupt between different systems. Understanding this map is the first step toward resolving any dispute, because the level at which a conflict sits often decides how it should be tackled.

Who was Johan Galtung and why his classification matters 🔗

Johan Galtung (1930-2024) built the academic discipline of peace research almost from scratch. He founded the Peace Research Institute Oslo (PRIO) in 1959 and went on to produce concepts that are now standard in the field, including structural violence, cultural violence, and the well-known conflict triangle. His goal was never abstract theory for its own sake. He wanted tools that practitioners, diplomats, and ordinary citizens could use to diagnose conflict and design solutions.

Galtung treated peace much like his physician father treated illness, in terms of diagnosis, prognosis, and therapy, viewing peace as a continuous process of repairing social and political wounds rather than the mere absence of fighting. His classification of conflict types fits this medical logic. Before you can prescribe a remedy, you must correctly identify the kind of conflict you are dealing with. A misdiagnosis here can be as damaging in social terms as it is in medicine.

The four types of conflict 🔗

Galtung’s framework organises conflicts by the actors involved, producing four recognisable categories. These categories scale upward, from the individual mind to entire communities and nations. A widely used peacebuilding reference summarises them clearly: intrapersonal conflicts are debates that occur within us, interpersonal conflicts occur between two or more people, intra-group conflicts occur within the same group, and inter-group conflicts occur between groups such as communities, organisations, and nations.

Intrapersonal conflict 🔗

This is conflict occurring inside a single individual. It arises when a person holds contradictory desires, beliefs, or emotions at once. Intrapersonal conflicts include things like a guilty conscience or an identity crisis. A common example is a student torn between pursuing a creative passion and choosing a financially secure profession that the family expects. The tension is real, but it lives entirely within one mind. No external opponent is involved, which is why this type is the easiest to overlook and yet often the seed from which larger conflicts grow.

Interpersonal conflict 🔗

Interpersonal conflict occurs between two or more individuals. These are the most visible and familiar disputes because they involve observable behaviour like arguments and disagreements. Quarrels between friends, siblings, neighbours, or colleagues all fall here. They usually stem from differences in opinions, values, interests, or competition over scarce resources. Because the parties are distinct people, resolution typically depends on communication, listening, and finding mutually acceptable terms.

Intragroup conflict 🔗

Intragroup conflict happens among members of the same group. A political party splitting into factions, disagreements within a family business, or tensions inside a college committee are all intragroup. Research on organisational teams identifies recognisable forms of this conflict, with the American Psychological Association noting three intra-conflictual problems in teams: process, relationship, and task. Such conflicts can either paralyse a group through endless friction or, when handled well, sharpen its decisions through healthy debate.

Intergroup conflict 🔗

Intergroup conflict is conflict between two or more distinct groups. This category covers the largest and often the most destructive disputes, including those between communities, religious or ethnic groups, organisations, and nation-states. Communal tensions, labour-versus-management disputes, and interstate wars all belong here. Because entire collectives are involved, intergroup conflicts carry high stakes and are usually the hardest to resolve, often demanding mediation, negotiation, and structural reform.

Intrasystem versus intersystem conflicts 🔗

The four types tell us who is in conflict. Galtung adds a second, equally important dimension that tells us where the boundary lies. This is the distinction between intrasystem and intersystem conflict. A “system” here can mean a single person, a single group, a single organisation, or a single state. The question is whether the dispute stays inside one system’s boundary or crosses between two separate systems.

Intrasystem conflicts 🔗

An intrasystem conflict occurs within a single system. The struggle is internal, and no outside party is required for it to exist. An intrapersonal conflict, a battle of competing values inside one person, is the clearest example because the entire dispute is contained within that individual. Likewise, an intragroup conflict is intrasystem when it stays within the boundaries of one group, such as rival factions inside the same political party. The defining feature is that the system is essentially in conflict with itself, struggling to reconcile its own internal contradictions.

Intersystem conflicts 🔗

An intersystem conflict occurs between two or more distinct systems. Here the boundary of the dispute crosses from one self-contained unit to another. A diplomatic dispute between the representatives of two countries is a useful illustration: although it may look like a disagreement between two individuals, each person represents a much larger system, so the conflict is genuinely between systems. Intergroup conflicts, by their nature, are usually intersystem, because they pit one collective against another. These disputes tend to carry wider consequences, since the outcome affects the larger systems standing behind each party rather than just the individuals at the table.

The two dimensions can be combined to give a richer reading of any conflict. A disagreement between two diplomats can be described at once as interpersonal in form and intersystem in scope. This layered description is precisely what makes Galtung’s framework so useful: it captures both the human face of a conflict and the structural weight behind it.

How conflicts escalate across the levels 🔗

One of the most practical insights from this classification is that conflicts rarely stay neatly in one box. They tend to migrate upward through the levels if left unaddressed. A workplace dispute can show this progression clearly. It might begin with an employee feeling undervalued, which is intrapersonal, then create friction with a supervisor, which is interpersonal, then split the department into rival camps, which is intragroup, and finally pull in other departments or unions, which becomes intergroup.

History shows the same pattern at a grander scale. Analysts note that many wars began with individual leaders’ personal grievances, escalated through diplomatic failures between representatives, created internal political divisions, and ultimately erupted into full-scale conflicts between nations. Recognising where a conflict currently sits, and which way it is likely to move, allows for early intervention before a manageable internal tension hardens into a destructive clash between groups.

Connecting the classification to Galtung’s wider theory 🔗

Galtung’s typology of conflict types does not stand alone. It connects to his famous conflict triangle, which holds that every conflict has three interlinked elements. As an International Baccalaureate politics resource explains, Galtung theorised a triangle with three interdependent points: behaviour, attitudes or assumptions, and contradictions, and separated it into a manifest and a latent level. Whether a conflict is intrapersonal or intergroup, intrasystem or intersystem, it still contains these three elements. The classification tells you the level and the scope; the triangle tells you the internal mechanics.

This combined toolkit is why Galtung’s work remains relevant for analysing modern disputes, from civil conflicts to interstate wars. The same framework can be scaled to examine contemporary wars such as the Russia-Ukraine conflict, demonstrating that a model built decades ago still maps onto today’s complex realities.

Why the classification matters for conflict resolution 🔗

The central payoff of Galtung’s classification is that different conflicts demand different remedies. There is no single technique that works for every dispute, so correctly placing a conflict is the foundation of any sensible resolution strategy. The practical benefits are worth spelling out.

Tailored resolution strategies: An intrapersonal conflict may call for reflection, counselling, or clearer priorities, while an intergroup conflict may require formal negotiation, third-party mediation, and reform of the underlying structures. Matching the method to the level dramatically improves the odds of success.

Preventing escalation: Because conflicts move upward through the levels, addressing them early keeps them contained. Resolving an intrapersonal or interpersonal tension before it spreads can stop it from hardening into an intragroup split or an intergroup confrontation.

Promoting empathy: Identifying the type and scope of a conflict encourages people to see the situation from multiple perspectives. This is especially valuable in intergroup disputes, where understanding the system behind an opponent can replace hostility with dialogue.

Addressing root causes: Galtung consistently argued that lasting peace requires tackling the structural and cultural roots of violence, not just its visible behaviour. His framework pushes us to ask whether a conflict is truly between two people or whether it reflects a deeper clash between systems, which is exactly where durable solutions must be aimed.

Used together, the four conflict types and the intrasystem-intersystem distinction give students, mediators, and policymakers a shared language for describing disputes precisely. That precision is not academic decoration. It is the practical groundwork for choosing the right approach, intervening at the right moment, and building peace that lasts.

What do you think? Can you identify a recent dispute in your own life or in the news and classify it using Galtung’s framework, deciding both its type and whether it is intrasystem or intersystem? And do you think internal, intrasystem conflicts deserve more attention than they usually receive, given how often they appear to be the starting point for larger clashes between groups?
