If functionalism's central question was how societies hold together, conflict theory's is how they are held together — by whom, at whose cost, and against what opposition.

It is not simply Marxism. Its two founding figures were both refugees from Nazi Europe, both anti-Communist, and both explicitly arguing that a general sociology of conflict was needed because Marxism had got the specifics wrong while getting the framing right.

Coser: the functions of social conflict

The Functions of Social Conflict (1956) does something unexpected: it argues for conflict's importance using functionalist logic, by systematically developing Simmel's essay on conflict (4.4.1).

And Coser's crucial qualification, which distinguishes his position from an endorsement of conflict: the functions depend on the type of conflict and the structure of the group.

Conflict over basic values threatens a group's existence; conflict over means, allocation or terms within a shared framework strengthens it. Loosely structured, pluralistic societies tolerate and benefit from frequent conflicts, because multiple crosscutting conflicts (4.4.2) prevent any single cleavage from splitting the society. Rigidly structured societies suppress conflict, which accumulates, and when it breaks out it does so along a single line, catastrophically.

This yields a genuine and testable proposition: societies that permit frequent small conflicts are more stable than those that permit none.

Dahrendorf: authority and imperatively coordinated associations

Dahrendorf's Class and Class Conflict in Industrial Society (1959) offers a general theory of conflict, and its key move is to replace Marx's variable.

The structural consequences are what make the theory interesting:

Conflict is universal and permanent, because every organisation has an authority structure. There is no society without conflict, because there is no society without organisation.

Conflict is plural, not singular. A person is in authority in one association and subject to it in another — a foreman commands on the shop floor and obeys at the union branch, a bishop commands a diocese and obeys a synod. Multiple crosscutting conflicts, not a single class war, which is Simmel's affiliation argument (4.4.2) applied to power.

Class is redefined as conflict group formed from an authority position, not from property. This is a substantial departure from Marx and it is the theory's most contested element.

And the quasi-group becomes an interest group only under specifiable conditions: technical (organisation, leadership, an ideology), political (freedom to associate), and social (communication and recruitment). This is 4.1.8's problem, restated with the conditions named.

The two frameworks compared

Randall Collins: conflict theory made micro

The most substantial development, and the one that connects this Topic to the rest of Part 5.

Randall Collins, Conflict Sociology (1975), argued that conflict theory had remained too macro and needed microfoundations (4.2.8) — an account of what people actually do, in encounters, that produces the large patterns.

Collins later synthesised this with Durkheim's ritual theory into Interaction Ritual Chains (2004) (4.2.6), producing what is arguably the most complete micro-macro theory anyone has built — conflict, ritual and emotional energy in one framework.

Where conflict theory sits now

It won, in a specific sense: the assumption that societies are arenas of competing interests, that institutions distribute advantage unevenly, and that conflict is normal rather than pathological is now the discipline's default. Almost nobody argues otherwise.

Which means it stopped being a distinct school. There is no "conflict theory department." Its assumptions were absorbed into stratification research, political sociology, social movement theory, organisational sociology and the sociology of education, and the label is now largely a textbook category.

The criticisms that remain live:

Is authority really dichotomous? Dahrendorf's insistence that one either has authority or does not is hard to sustain against the enormous gradations of real organisations, and against Wright's contradictory class locations (4.1.3).

Does the plurality of conflicts explain their patterning? If everyone is in authority somewhere and subject to it elsewhere, why do conflicts nonetheless line up so consistently along class, race and gender? Dahrendorf's framework predicts more randomness than we observe.

And has conflict theory lost the analysis of what conflict is about? Coser's forms and Dahrendorf's authority relations are formal categories, and the objection is Simmel's (4.4.1): treating conflict as a form abstracts from the content, and the content — exploitation, exclusion, domination — is what people are actually fighting over.

Why it matters

It supplies the discipline's default assumption, so thoroughly that it is now invisible: that societies contain groups with opposed interests, that institutions distribute advantage, and that conflict is ordinary. Almost all contemporary sociology proceeds on this basis.

It gives you two diagnostic tools you will use repeatedly. Realistic versus non-realistic conflict — would this end if the stated demand were met? And the safety valve test — does this procedure carry the grievance to someone who can act, or absorb it?

It reframes what stability is. Dahrendorf's argument that regulated conflict, not the absence of conflict, is what stable societies achieve is a genuinely useful correction to both the functionalist assumption that peace means consensus and the revolutionary assumption that regulation means suppression.

And it demonstrates Dahrendorf's methodological point, which is the most transferable thing in the lesson: two frameworks describing the same object, neither reducible to the other, selected by question. That is what having read Part 4 was supposed to equip you for, and this Topic is the first place Part 5 requires it.
