Introduction
Sociologically, marriage is an institutionalised social arrangement that regulates sexual access, economic cooperation, lineage, and reproduction across societies. Rather than being merely a biological or religious union, marriage is a multifaceted social institution interpreted through diverse theoretical paradigms that examine its structural functions, power dynamics, and evolving meanings.
1. Functionalist Perspective
Functionalist sociologists conceptualise marriage as an indispensable, stabilizing social institution that fulfills vital functions necessary for social equilibrium and continuity.
- George Peter Murdock: In his cross-cultural study of 250 societies, Murdock identified marriage within the nuclear family as universal, fulfilling four essential functions: sexual regulation, economic cooperation, reproduction, and socialisation.
- Bronislaw Malinowski: Formulated the 'principle of legitimacy', arguing that marriage exists primarily to assign a socially recognised father to a child, thereby establishing social status and preventing illegitimacy.
2. Structural and Alliance Perspective
Alliance theorists shift focus from reproduction to the creation of social networks and social integration across distinct kinship groups.
- Claude Lévi-Strauss: In his structuralist alliance theory, Lévi-Strauss posited that the universal incest taboo compels exogamy. Marriage functions as a system of reciprocal gift exchange—specifically the exchange of women between kin groups—transforming hostile relations into durable alliances and cementing social solidarity.
3. Marxist and Conflict Perspective
Conflict theorists view marriage not as a consensus-building mechanism, but as an ideological and material apparatus rooted in property relations and inequality.
- Friedrich Engels: In The Origin of the Family, Private Property and the State, Engels argued that the rise of private property precipitated monogamous marriage. It emerged as an economic institution designed to ensure the paternity of offspring for patrilineal inheritance, marking the 'world-historic defeat of the female sex'.
4. Feminist Perspectives
Feminist sociologists deconstruct marriage as an institutionalised site of patriarchal control and female subordination.
- Christine Delphy and Diana Leonard: From a materialist feminist standpoint, they analyse marriage as a patriarchal labour contract where men exploit and expropriate women's unpaid domestic and emotional labour.
- Ann Oakley: Emphasises how the conventional division of domestic labour within marriage restricts women's autonomy, sustaining gender roles and reinforcing female economic dependency.
5. Symbolic Interactionist Perspective
Rather than treating marriage as a fixed macro-structure, interactionists focus on the everyday micro-level negotiation of identities and meanings.
- Peter Berger and Hansfried Kellner: Conceived marriage as a continuous, nomos-building conversation in which two individuals reconstruct their biographies and establish a shared social reality, validating each other's subjective world in an otherwise alienating society.
6. Late-Modern and Postmodern Perspectives
Sociologists of late modernity highlight the reflexive de-institutionalisation and individualisation of marital bonds.
- Anthony Giddens: Argues that traditional marriage is increasingly replaced by the 'pure relationship', founded on confluent love and plastic sexuality—where relationships are sustained solely as long as they provide mutual emotional satisfaction, rather than duty or economic necessity.
- Andrew Cherlin: Highlights the 'de-institutionalisation of marriage', wherein cultural norms regulating marital roles weaken, rendering marriage an optional marker of prestige and individual achievement rather than an essential social transition.
Conclusion
The sociological understanding of marriage has transitioned from viewing it as a static religious sacrament or functional necessity to recognising it as a fluid, reflexively negotiated partnership. Contemporary phenomena—ranging from increasing cohabitation to legal contestations over same-sex marriage, as seen in the Supriyo judgment—demonstrate that marriage continues to evolve into a rights-oriented, egalitarian institution.
