Comparative Politics

18th century to present

The systematic study of how political institutions, customs, and practices vary across different societies and historical periods.

The systematic study of how political institutions, customs and practices vary across societies and periods, looking for patterns and explanations rather than treating each case in isolation. Its governing assumption is that political arrangements can be explained rather than merely narrated, and that comparison is the closest thing political science has to an experiment.

Aristotle began it by collecting and classifying constitutions, and the method was recovered by Montesquieu, whose Spirit of the Laws (1748) tied political forms to climate, commerce, religion and the size of territory. Tocqueville treated America as a laboratory for understanding democratic society in general rather than as a country worth describing for its own sake, and Weber extended the comparative method across civilizations to ask why bureaucratic rationalization had taken hold where it did.

The field professionalized after the war and has swung between methods since. The behavioral revolution pushed toward survey data and quantification; area specialists objected that statistical work on incomparable cases produces precision without understanding; the historical-institutionalist turn re-established sequence and path dependence as explanations. Its durable findings tend to be conditional rather than lawlike: Lijphart on how consociational arrangements hold divided societies together, Przeworski on the relationship between development and the survival of democracies, Linz on why presidential systems are more fragile than parliamentary ones.

The field's recurring methodological problem is that it has many variables and few cases — there are only so many countries, and they are not independent of one another. Its current work on democratic erosion has made that limitation newly visible, since the cases most worth explaining are still in progress.

Lineage

Descends from

  • Aristotelianism4th century BC, revived repeatedly

    The method begins with the collection of 158 constitutions: describe what exists, classify it, and generalize afterward.

  • Enlightenment Philosophy18th century

    Montesquieu's Spirit of the Laws established the comparative method — regimes explained by climate, custom and scale rather than by first principles.

Gave rise to

  • Political SociologyLate 19th century to present

    Tocqueville's comparison of democratic societies is the direct methodological ancestor of Weber's and Michels's sociology of political forms.

Converges with

  • Political SociologyLate 19th century to present

    Weber worked in both, and the question of how social structure produces political form belongs to each without either owning it.
