Political Sociology Approach to Comparative Politics

Comparative Politics: nature and major approaches; political economy and political sociology perspectives; limitations of the comparative method.

This article covers the political sociology perspective in full — its classical and modern origins, its scope and research areas, its three theoretical frameworks, cleavage theory, the Indian literature, and its limitations.

Official Syllabus: Paper II, Section A, Unit 1

The same institution, transplanted, does different work. Democracy may promote stability in the United States and produce fragmentation or anarchy in states with weak societal cohesion. A written constitution modelled on one country’s may deliver constitutional government in one place and a facade in another. Federalism holds India together and split Yugoslavia apart.

No account of the institution itself can explain this, because the institution is the same in each case. What differs is the society into which it was placed — and political sociology is the approach built on that observation.

Its defining subject is the interface: the interaction between decision-making authorities and conflictual social forces and interests. Where formal political science asks what a legislature is empowered to do, political sociology asks who the legislators are, whose interests they carry, what social divisions their party expresses, and which groups were never in the room.

It has been for several decades the most prominent approach in comparative politics, particularly for the analysis of post-colonial and developing states — precisely where the gap between constitutional text and political reality is widest, and where the society underneath the constitution therefore does most of the explanatory work.

Its success also created its central problem. Political sociology succeeded so completely that political scientists began to fear the discipline was dissolving into sociology, and the reaction to that fear — Skocpol’s call to bring the state back in — is one of the defining moves of modern comparative politics.

• Political sociology deals with issues located at the interface of politics and society. It examines how political institutions interact with society, and how social cleavages, movements and ideologies shape state behaviour and policy outcomes.
• Its central explanatory claim is the one stated at the outset: it explains why the same political institutions function differently across societies.
• Sartori’s distinction is the one to get right, because it separates the approach from a reductionism frequently mistaken for it.
  • The sociology of politics is sociology applied to political material: it treats political phenomena as dependent variables to be explained by social ones, and politics has no independent existence in it.
  • Political sociology proper is a genuine hybrid, in which the causal traffic runs both ways — society shapes politics, and political institutions, leadership and state action reshape society.
  • Everything that later went wrong with the approach can be traced to the first being practised under the name of the second.
• The relationship to its neighbours is worth stating precisely.
  • Against political science narrowly conceived, it insists that formal institutions cannot be understood apart from their social base.
  • Against political economy, it holds that material interest is one determinant among several, and that status, identity, religion, ethnicity and culture are not reducible to it.
  • Against political culture, it locates orientations in social structure and group membership rather than treating them as free-floating attitudes.

History and Evolution

The classical origins

• Aristotle, regarded as the father of political science, is also considered one of the earliest contributors to political sociology.
  • In his theory of revolution he identifies sociological factors — rising economic inequality and class conflict — as the root causes of political upheaval, and his account of stasis is a causal sociology of regime breakdown rather than a moral condemnation of it.
  • His proposition that a large middle class stabilises a polity, because it prevents the polarisation of rich against poor, is the first sociological hypothesis about regime durability, and it is still being tested.
• Ibn Khaldun’sMuqaddimah is the most systematic pre-modern political sociology.
  • His concept of asabiyyah — group feeling or social solidarity — explains the rise and fall of dynasties by the strength and decay of the cohesion underlying political power, in a cycle of roughly three generations — about 120 years.
  • It is a theory of the state derived entirely from social structure, and it has no equivalent in the European tradition until the nineteenth century.
• Machiavelli also provided early sociological insight, suggesting that the form of government depends on the nature of society — so that a corrupt society requires an authoritarian ruler to maintain order, while an uncorrupt one can sustain a republic.
• Montesquieu related forms of government to climate, religion, commerce and manners; Tocqueville explained American democracy through associational life, equality of condition and religion; and Comte and Saint-Simon supplied the founding ambition of a science of society capable of guiding politics.
• These thinkers together establish the discipline’s founding proposition: politics cannot be studied in isolation from the social environment in which it operates.

Marx and the modern origin

• Karl Marx is considered the father of modern political sociology. It was Marx who argued that to understand politics one must first understand the basic structure of society, and that politics cannot be studied independently.
• The base and superstructure model supplies the method: politics belongs to the superstructure and is shaped by the economic foundation of society. This is a materialist method of analysis, in which the economic class structure determines political outcomes.
• Its contribution to political sociology specifically is the demonstration that the state has a social base — that governments represent constellations of social forces rather than the nation as an undivided whole — which is the premise every subsequent political sociology accepts, including those that reject Marx’s economics.
• Its defect is equally consequential. The explanation is monocausal: everything runs back to the relations of production, and social divisions that do not reduce to class have no independent existence in the theory.

Weber and the second school

• In opposition to this monocausal explanation, Max Weber developed the Weberian school of political sociology. Weber criticised Marx for ignoring the role of ideas, culture and non-economic factors such as religion and authority.
• The result is that two dominant schools of political sociology emerged: the Marxist and the Weberian, and almost all subsequent work in the field belongs to one, the other, or a deliberate synthesis.
• Weber’s specific contributions are the tools the field actually uses.
  • The three dimensions of stratification — class (economic position in the market), status (social honour and lifestyle) and party (organised pursuit of power). This is the single most important correction to Marx in the whole of political sociology: it establishes that social hierarchy has more than one axis, that they can move independently, and that a group may be high in status and low in class, which is exactly the situation of the impoverished Brahmin and the wealthy Shudra that Indian sociology has spent a century analysing.
  • The three types of legitimate authority — traditional, charismatic and rational-legal — which classify political systems by the grounds on which obedience is given rather than by their formal structure.
  • The analysis of bureaucracy as the characteristic institution of rational-legal domination, and the warning that it becomes an iron cage whose efficiency is purchased at the cost of freedom and meaning.
  • The Protestant ethic argument, whatever its historical accuracy, established the general claim that ideas can be causes and not merely reflections — which is what makes the Weberian school a genuine alternative rather than a variant.
• Weber’s own preference was for rational-legal authority, which he regarded as the basis of modern capitalism and the modern state, and his emphasis on an independent, competent, hierarchical bureaucracy is an important component of modern comparative politics. Marx considered capitalism irrational; for Weber it was rational and natural.

The elite theorists

• The Italian elitists are political sociology in its purest form, since their entire argument is that the social composition of the ruling group, not the constitutional form, determines how a system works.
  • Vilfredo Pareto distinguished the governing from the non-governing elite, classified rulers as lions (who rule by force) and foxes (who rule by cunning), and described history as the circulation of elites — a cemetery of aristocracies, in which one ruling group replaces another and the fact of elite rule never changes.
  • Gaetano Mosca established the political class: in every society there is a ruling minority and a ruled majority, and the minority rules because it is organised. His concept of the political formula — the doctrine by which a ruling class justifies itself — anticipates both ideology critique and Gramsci’s hegemony.
  • Robert Michels produced the iron law of oligarchy from the study of the German Social Democratic Party — the most democratic organisation of its time. Who says organisation says oligarchy. Large-scale organisation requires specialisation, specialisation creates a leadership with distinct interests, and leadership entrenches itself. The finding is devastating precisely because it was derived from a socialist party rather than asserted against one.
• The elitist theory of democracy became a central example of behavioural-empirical research, and its finding that power rests with elites whether a system is socialist or liberal was read by Marxists as a Cold War weapon and by liberals as a realistic reduction of democratic expectations.

The behavioural transformation

• Political sociology was further influenced by the behavioural revolution, and scholars such as David Easton argued that instead of merely analysing institutions, the broader socio-cultural environment must be studied — a point of particular importance in developing countries, where formal institutions may not function as intended.
• Behaviouralists expanded political sociology by encouraging empirical research, survey-based studies and the analysis of political behaviour, making the field data-driven and grounded in social realities rather than speculative.
• Two American research traditions did most of the work.
  • The Columbia school under Lazarsfeld, in The People’s Choice, found that voting was predicted best by social characteristics — class, religion and place of residence — rather than by campaign persuasion, and produced the two-step flow model of opinion leadership. Its formulation was frankly sociological: a person thinks politically as they are socially.
  • The Michigan school, in The American Voter, replaced social determination with party identification as a durable psychological attachment acquired through socialisation — the funnel of causality that moved the field from sociology towards political psychology.
• The methodological consequence for comparative politics was decisive: cross-national survey research became possible, and with it the comparison of social bases of political behaviour across countries.

Scope and the Four Areas of Research

• Political sociology has become one of the most prominent approaches in comparative politics, especially in analysing post-colonial, developing states. Its four established research areas map the field.

1. The socio-political formation of the modern state

• Examines how states emerged from feudal or colonial societies, and how social forces influenced their political structure.
• Barrington Moore’sSocial Origins of Dictatorship and Democracy is the founding text of comparative historical sociology, and its argument is the most-cited proposition in the field.
  • Three routes to the modern world, determined by the relations between landed upper classes, the peasantry, the bourgeoisie and the state:
    • Bourgeois revolution producing liberal democracy — England, France, the United States, where a commercialising landed class allied with or was displaced by a strong bourgeoisie and the peasantry was destroyed as a class.
    • Revolution from above producing fascism — Germany and Japan, where a weak bourgeoisie allied with a labour-repressive landed aristocracy and modernisation was carried out by the state without political liberalisation.
    • Peasant revolution producing communism — Russia and China, where a large, cohesive peasantry confronted a landed class that extracted without modernising.
  • His epigram states the conclusion: no bourgeois, no democracy.
  • His chapter on India is the awkward and interesting case — a fourth route in which democracy was achieved without either bourgeois revolution or peasant revolution, at the price, he argued, of a stagnant agrarian structure and enormous unregistered suffering.
• Charles Tilly’s account is the sharpest single-sentence theory in the field.

“War made the state, and the state made war.” — Tilly

• European states were built by rulers extracting resources to fight, and the bargaining over that extraction produced representative institutions, taxation systems and citizenship rights. His comparison of coercion-intensive, capital-intensive and capitalised-coercion paths explains why European states took such different forms.
• Theda Skocpol’s States and Social Revolutions compares France, Russia and China and reaches a structural conclusion that inverts the revolutionary tradition: revolutions are not made, they come. They occur when a state’s administrative and military capacity collapses under international pressure while agrarian structures permit peasant revolt — the state’s own crisis, not the revolutionaries’ will, is the causal centre.
• The post-colonial state is the area’s most important comparative extension, and Hamza Alavi’s overdeveloped state — an apparatus built to dominate all indigenous classes and therefore larger than the society it inherited — is its founding concept.

2. The impact of social inequality on politics

• Analyses how caste, class, gender and religion affect political participation, representation and policymaking.
• Lipset’s Political Man established the comparative study of the class basis of voting — the finding that in every Western democracy the working class voted left and the middle class right, and the subsequent study of why that relationship weakened.
• Race, ethnicity and language enter as cleavages that are not reducible to class and frequently cut across it, which is what makes the politics of divided societies a distinct field.
• Gender enters both as a dimension of political exclusion and as a critique of the field’s categories: the public–private distinction on which political sociology built its boundary is itself the mechanism by which women’s subordination was placed outside politics.
• Intersectionality, from Kimberlé Crenshaw, supplies the current methodological standard: categories of disadvantage compound rather than add, and the position of a Dalit woman is not the sum of caste disadvantage and gender disadvantage measured separately.

3. The role of informal political processes

• Studies how public opinion, ideologies, social movements and pressure groups influence formal political institutions and decision-making.
• Social movement theory is the area’s most developed body of comparative work.
  • Resource mobilisation theory shifted the question from why people are aggrieved — since grievance is constant — to when they can organise, making resources, networks and organisation the variables.
  • Political process theory, from Tilly, Tarrow and McAdam, adds the political opportunity structure: movements succeed when the political system opens — through elite division, unstable alignments, new allies or reduced repression. This makes movement success a property of the political system rather than of the movement, which is the properly comparative formulation.
  • New social movement theory — Touraine, Melucci, Habermas — argues that post-industrial movements over environment, gender, identity and peace are organised around identity and meaning rather than material distribution, and operate on civil society rather than on the state.
• Public opinion, ideology and the media complete the area, and the question of who sets the agenda is where it meets the study of power.

4. Power relations within and between social groups

• Explores how institutions like the family, media, bureaucracy and religious bodies participate in shaping political attitudes and behaviour.
• Pierre Bourdieu is the indispensable modern contributor, and his apparatus has become standard.
  • Habitus — durable dispositions acquired through social position, which generate practice without conscious calculation.
  • Field — the structured arena of competition, with the political field having its own rules, stakes and entry conditions.
  • Forms of capital — economic, cultural (education, taste, credentials), social (networks) and symbolic — convertible into one another, so that advantage is transmitted across generations through mechanisms no law addresses.
  • Symbolic power — the power to make people see and believe, to impose the legitimate vision of the social world. This is the most useful single concept for analysing how political domination is reproduced without visible coercion.
• Michael Mann’s The Sources of Social Power supplies the field’s most ambitious comparative framework — the IEMP model of ideological, economic, military and political power networks, which refuses to grant primacy to any one, and the distinction between despotic power (what a state can do to society without negotiation) and infrastructural power (its capacity to penetrate society and implement decisions). A state can be high in one and low in the other, and most post-colonial states are.

The Three Theoretical Frameworks

1. Pluralism

• Pluralism views politics as a competition among multiple interest groups, each trying to influence public policy, with no single group dominating all areas.
• Its ancestry runs from Bentley’s group theory through David Truman’s The Governmental Process to Robert Dahl’s Who Governs?, whose study of New Haven found different elites prevailing in different issue areas — the empirical foundation of the claim that power is dispersed.
• Dahl’s concept of polyarchy is its comparative instrument: real democracies are not rule by the people but systems characterised by contestation and inclusiveness, measurable and comparable across countries.
• The critique is where the interesting argument lies.
  • Bachrach and Baratz identified the second face of power — non-decision-making, control over which issues reach the agenda at all. Dahl’s method could only observe conflicts that surfaced.
  • Lukes’s third dimension goes further: power works best when it prevents grievances from forming, shaping what people accept as natural. A method that studies observable conflict cannot detect a conflict that never occurs.
  • Schattschneider’s verdict is the most quotable and the most damaging: the flaw in the pluralist heaven is that the heavenly chorus sings with a strong upper-class accent. Organisation is itself unequally distributed, and Olson’s logic of collective action explains why: concentrated interests organise and diffuse ones do not.

2. Elite or managerial theory

• Elite theory argues that power is concentrated in the hands of a small elite, such as political leaders or bureaucratic managers, and Weber and Theda Skocpol have contributed to this approach.
• In modern conditions the elite are leaders and those with strong organisational and managerial skill, which is why the managerial variant matters: the argument is not about inherited status but about the control conferred by running large organisations.
• C. Wright Mills’s The Power Elite is the classic American statement: a unified elite drawn from the corporate, political and military hierarchies, connected by shared social origins, interchange of personnel and common interest, making the decisions of consequence while the visible politics of parties and Congress operates at the middle level.
• James Burnham’s The Managerial Revolution anticipated the argument by locating power in those who control the means of production rather than those who own them — a claim that applies to state socialism as much as to corporate capitalism.
• Skocpol’s contribution converts elite theory into state-centred analysis: state officials constitute an elite with interests of their own, arising from their position, distinct from those of any social class — which is the foundation of the neo-Weberian tradition.

3. Class analysis

• This framework sees the capitalist class as the dominant force controlling political power, with politics viewed as a reflection of class struggle and the economic base. The propertied class influences and operates politics.
• Its modern versions have moved a long way from instrumentalism.
  • Poulantzas’s relative autonomy — the state serves capital in general precisely by being independent of any particular capitalist.
  • Miliband’s demonstration of elite social composition and interlocking networks.
  • Erik Olin Wright’s contradictory class locations answers the standard objection that the two-class model does not fit modern societies: managers, supervisors and professionals occupy positions with attributes of both capital and labour, which is why their politics is unstable.
• Its comparative payoff is strongest where class formation itself is the variable — explaining why labour movements produced social democracy in Scandinavia, business unionism in the United States and revolutionary parties elsewhere.

4. The state-centred fourth

• The three-fold classification omits what became the dominant framework after 1979, and it should be added.
• Bringing the state back in treats the state as an actor with autonomous interests and capacities, not as an arena for social forces or an instrument of a class.
• State capacity and state autonomy are its two variables, and Evans’s embedded autonomy and Mann’s infrastructural power are its operational concepts. It is the point at which political sociology recovers politics from society.

Political sociology’s founding proposition is that a constitution is only half an explanation — the other half is the society it was written for.

Cleavage Theory

• Cleavage theory is political sociology’s most successful export to comparative politics, because it explains the single most-compared feature of democratic systems: why party systems differ.
• A cleavage is more than a social division. Its three components are essential:
  • An empirical social division — class, religion, region, language, ethnicity.
  • A collective identity — the members must recognise themselves as a group.
  • An organisational expression — a party, union, church or association that gives the division political form.
  • Without all three it is a social difference and not a cleavage, which is why a society can be deeply unequal and have no class politics.
• Lipset and Rokkan derived the party systems of Western Europe from two historical revolutions and the four cleavages they produced.

• The freezing hypothesis is the theory’s most famous and most tested claim.

“The party systems of the 1960s reflect, with few but significant exceptions, the cleavage structures of the 1920s.” — Lipset and Rokkan

• Party systems froze at the moment of mass enfranchisement and reproduced themselves thereafter, long after the divisions that generated them had faded.
• The mechanism is critical junctures: the sequence in which cleavages became politically salient, and the alliances formed at the moment universal suffrage arrived, determined a structure that survived long after the divisions that generated it had faded.
• This is path dependence in political sociology before the term existed, and it is why the approach and historical institutionalism are so closely related.
• The subsequent critique is now larger than the theory.
  • Dealignment — the weakening of stable class and religious voting since the 1970s, with rising electoral volatility, declining party membership and increasing numbers of voters without durable attachment.
  • Kirchheimer’s catch-all party describes the organisational response: parties shed ideological baggage and social-group anchorage to compete for the whole electorate, which loosened the cleavage moorings further.
  • Katz and Mair’s cartel party carries it to its conclusion: parties become agents of the state rather than of society, funded publicly and colluding to limit competition — the complete detachment of party from social base that cleavage theory said was impossible.
• The transnational cleavage is the field’s most important current finding, and it substantially revises Lipset and Rokkan.
  • Hooghe and Marks identify a new division between those defending national political, social and economic ways of life against external actors who penetrate the state, and those embracing transnational integration. Its immediate content is European integration and immigration.
  • Its social base is stratified above all by education. Those with limited education tend towards exclusive national identity and Euroscepticism; the more educated display cosmopolitan attitudes. Economic precarity reinforces the division: those without mobile assets resent a transnationalism that dilutes the protections of citizenship and increases competition.
  • It maps onto the GAL–TAN dimension — green, alternative, libertarian against traditional, authoritarian, nationalist — with radical right parties at the TAN pole and green parties at the GAL pole.
  • The theoretically decisive point is how it relates to the older cleavages. It emerged after competitive party systems already existed, and it has not replaced the earlier divisions. It creates layers of partisan attachment, coexisting with weakened but persistent older dimensions. New cleavages now emerge alongside established ones rather than displacing them — which is a fundamental amendment to the freezing hypothesis rather than a refutation of cleavage theory itself.
  • Kriesi’s parallel formulation of an integration–demarcation divide between the winners and losers of globalisation reaches the same structure from the political-economy side.
• The Indian cleavage structure is the comparative counter-case, and it is the reason India is indispensable to the theory.
  • India’s cleavages — caste, religion, language, region, class and tribe — are numerous and, crucially, cross-cutting rather than mutually reinforcing. A person’s caste, language, religion and class place them in different coalitions on different questions.
  • Cross-cutting cleavages moderate conflict; reinforcing cleavages intensify it. Where every division falls along the same line, society splits into two hostile blocs; where they cut across, today’s opponent is tomorrow’s ally.
  • This is the standard structural explanation for why India held together and Yugoslavia did not, and it is a finding generated from the Indian case rather than applied to it.

Political Sociology in the Indian Context

• Political sociology has been widely applied in analysing Indian politics, and the Indian literature is substantial enough to constitute a school.
• M. N. Srinivas supplied the foundational concepts.
  • Sanskritisation — the process by which a lower caste adopts the ritual practices, customs and ideology of a higher caste to claim higher status. It is mobility within the system rather than mobility against it, which is precisely why Ambedkar rejected it as a strategy.
  • The dominant caste — a caste with numerical strength, economic power through land, and ritual standing sufficient to control a locality. This is the single most useful concept for Indian electoral politics, because it explains local political control better than either class or ritual rank alone.
  • Westernisation completes his own apparatus. The related Great tradition / Little tradition distinction is Robert Redfield’s, applied to India by McKim Marriott, and Srinivas worked with it rather than coining it.
• André Béteille studied the role of caste in shaping political institutions, and his Caste, Class and Power in the Tanjore village of Sripuram is the classic empirical demonstration.
  • His finding is the one that matters: caste, class and power were once congruent and are progressively becoming disjoined. The harmonic system, in which ritual rank, economic position and political power coincided, has given way to a disharmonic one in which they do not.
  • This is Weber’s class–status–party distinction validated on Indian material, and it is why Béteille’s work is comparative sociology rather than area description.
• Rajni Kothari’sCaste in Indian Politics corrected the assumption that caste and modern politics were antagonistic.
  • His formulation is the standard one: it is not politics that gets caste-ridden, but caste that gets politicised. Politics does not corrupt caste; it transforms it, converting a ritual hierarchy into a set of horizontal interest groups capable of competitive mobilisation.
  • This is a direct refutation of modernisation theory’s expectation that traditional identities would dissolve, and it aligns with Rudolph and Rudolph’s The Modernity of Tradition, which showed that caste associations were vehicles of modernisation rather than its casualties.
• Paul Brass focused on the politics of religion and communalism, and his most important comparative contribution is the concept of the institutionalised riot system — the argument that communal violence in India is not spontaneous but produced by identifiable networks of specialists, and that its timing tracks political competition rather than religious feeling.
• Christophe Jaffrelot analysed the rise of the RSS and Hindutva politics, and separately produced India’s Silent Revolution on the political ascent of the lower castes — the shift of power in northern India from upper-caste elites to OBC leadership through the plebeianisation of politics after Mandal.
• Yogendra Yadav is known for his work on electoral behaviour and the sociology of voting in India.
  • His account of three electoral systems periodises Indian politics sociologically, and his identification of the second democratic upsurge — the entry of Dalits, Adivasis and OBCs into political participation at rates exceeding the privileged — is the most important empirical finding in Indian political sociology.
  • The participation gradient it produced inverts the Western pattern, in which participation rises with education and income, and constitutes a genuine Indian contribution to general theory.
• Ashutosh Varshney’s Ethnic Conflict and Civic Life is the strongest comparative design in the Indian literature: paired comparison of cities with similar demographics and very different records of communal violence, finding that inter-communal civic engagement — associational rather than merely everyday — is what prevents riots. Business associations, unions and clubs with mixed membership create the incentives and channels that defuse rumour.
• Sudipta Kaviraj’s distinction between fuzzy and enumerated communities explains what colonial census-taking did to Indian identity: fluid, overlapping, context-dependent belonging was converted into bounded, countable, mutually exclusive categories, which made majority-minority politics possible for the first time.
• Partha Chatterjee’s distinction between civil society — the domain of rights-bearing citizens, a minority — and political society — the negotiated, often extra-legal domain in which the majority of Indians actually deal with the state — is the most influential post-colonial revision of a core Western sociological category.
• The current moment is a political-sociology event of the first order. The Census of 2027 will carry comprehensive caste enumeration for the first time since Independence, following the Cabinet decision of April 2025 and a 40-question schedule notified in August 2026.
  • The entire literature on caste and politics has been built on estimate, extrapolation and the 1931 figures, and the enumeration will replace inference with data.
  • Kaviraj’s warning is the one to hold alongside it: enumeration does not merely measure identity, it hardens it — which is a claim the exercise will test at national scale.

Status, Critique and Limitations

The status question

• Political sociology once attracted great attention among political scientists, and then generated a specific anxiety: that it made politics too dependent on society, blurring disciplinary boundaries.
• As sociologists also began using the approach, political scientists feared that political science would lose its independent identity and be absorbed into sociology.
• Theda Skocpol’s call to bring the state back in is the response. While society shapes politics, political institutions and leadership also shape society, and political sociology must not ignore the autonomous role of the state.
  • The Indian illustration is the standard one: under Nehru’s charismatic leadership, Indian society underwent significant modernisation — an instance of political leadership acting upon society rather than expressing it.
• Political sociology has since grown so extensively in theory and research that it is treated as a hybrid discipline in its own right, standing between political science and sociology, rather than as a sub-approach within either.

Limitations

• Overemphasis on society. The approach tends to overstate the role of society in shaping politics, neglecting the autonomy of the state — which is precisely why Skocpol’s intervention was necessary.
• Neglect of institutional structure. It can downplay the formal rules, procedures and constitutional structures that also shape political behaviour and power dynamics. The same social structure produces different politics under different electoral systems.
• Ignorance of economic factors. It tends to underemphasise economic structures and interests, which is exactly what led to the separate development of the political economy approach in comparative politics. Political sociology can analyse a caste conflict at length and never arrive at the land ownership beneath it.
• Limited prescriptive utility. Being largely analytical and descriptive, it offers fewer concrete policy solutions or prescriptive frameworks for addressing crises of governance. It explains why a policy failed better than it says what to do instead.
• The risk of sociological reductionism — Sartori’s warning — in which political outcomes are read off from social structure, leaving no independent work for leadership, institutions or contingency.
• Static tendencies. Social structures change slowly, so an approach anchored in them explains stability far better than rapid political change — the freezing hypothesis’s own difficulty with dealignment is the illustration.
• Measurement and category problems in comparison. Caste, class, ethnicity and religion are not commensurable categories across societies, and cross-national datasets that treat them as a single variable called social cleavage are measuring different things in different places.

Contemporary Relevance

• The transnational cleavage has reorganised party competition across the democratic world, and it is the reason the class-based left-right axis no longer predicts vote choice as it did — the most consequential development in comparative political sociology in fifty years.
• The social bases of authoritarian populism are now the field’s most active research area, and the finding is consistent across countries: education, rather than income, is the sharpest single predictor of the new political division, which is a sociological fact with enormous political consequences.
• The sociology of social media has changed the study of informal political processes fundamentally. Movement mobilisation is faster and cheaper, and correspondingly shallower in organisational terms — the resource-mobilisation constraint has been relaxed without the organisational depth that used to accompany it, which explains the pattern of large movements that mobilise rapidly and dissipate without institutional residue.
• Ethnic and religious conflict remains the area where the approach does work no other can, and Varshney’s civic-engagement finding continues to generate policy-relevant comparative research.
• The caste census will produce, within two years, the largest new dataset in the history of Indian political sociology, and its analysis will be the field’s central Indian project for a decade.

Conclusion

Political sociology earned its dominance in comparative politics by answering the question that defeated every institutional approach: why the same rules produce different politics in different societies. Its concepts — cleavage, dominant caste, elite circulation, social capital, political opportunity structure, symbolic power — are the working vocabulary of the discipline, and they were nearly all generated by asking about the society underneath a political institution rather than about the institution itself.

Its besetting fault is the excess of its virtue. An approach built to show that society explains politics tends to conclude that society explains all of politics, at which point the state disappears as an actor, institutions become epiphenomena, and political science has nothing left of its own. Skocpol’s correction was not a rejection of political sociology but a restoration of its balance — society shapes politics, and politics shapes society, and a framework that cannot say the second is doing sociology of politics rather than political sociology.

While political sociology offers rich insights into how society and politics interact, it is not sufficient on its own. For a fuller understanding of political life it should be used alongside institutional and political economy approaches. Together they explain how ideas, institutions, power and material interests interact to shape political outcomes across different societies — which is the whole task of comparative politics, and no single approach has ever been equal to it.
