The Evolution of Marriage: Beyond Traditional Norms

Marriage is one of the oldest and most widespread social institutions in human history. Found across virtually every culture, it has served as a framework for organising relationships, raising children, managing property, and forging alliances between families. But what marriage means – who it includes, what it demands, and why people enter into it – has never been static. Today, the institution is undergoing some of its most significant shifts yet, driven by changing gender norms, legal reforms, and a growing emphasis on individual choice and companionship over tradition.

What do we mean by marriage? 🔗

According to the Encyclopaedia Britannica, marriage is a union regulated by laws, customs, beliefs, and attitudes that establishes the rights and duties of partners and provides status to any offspring. This is a broad definition, and that broadness is intentional – marriage looks different depending on where and when you examine it.

The sociologist Edward Westermarck, in his classic work History of Human Marriage, described marriage as a more or less lasting connection between male and female that extends beyond mere reproduction to include responsibility for offspring. Bronislaw Malinowski saw it more functionally – as a contract for the production and upbringing of children. Robert Lowie defined it as a relatively permanent bond between permissible mates.

Each of these definitions captures a piece of the puzzle, but none captures it fully. As historian Stephanie Coontz has argued, marriage likely began as an informal social arrangement for managing daily tasks, sexual relationships, and child-rearing – and only later became a mechanism for consolidating resources and transmitting property. In other words, marriage was never just one thing.

Marriage as a social institution: key functions 🔗

From a sociological standpoint, marriage provides a structure for regulating sexual behaviour and reproduction, establishing socially approved relationships, and ensuring stable environments for raising children. But its functions extend well beyond biology.

Regulating kinship and social identity 🔗

Marriage creates kinship networks. When two people marry, they connect not just to each other but to each other’s families. This has historically been crucial for building alliances, settling disputes, and organising communities. In ancient societies such as Egypt and Mesopotamia, marriages were often arranged by families specifically to strengthen social and economic ties.

Economic cooperation and inheritance 🔗

Marriage has long served as a unit of economic partnership. Spouses pooled labour and resources, and marriage determined how property was inherited across generations. During the medieval period in Europe, the Church sanctified marriage as a sacrament, and families often arranged matches to consolidate wealth and political power, with love being secondary.

Emotional fulfilment and companionship 🔗

The twentieth century brought a dramatic transformation – marriage shifted from being primarily institutional to being companionate, meaning spouses were now expected to be each other’s best friends, a role that earlier definitions never required. This was followed by a further shift toward what the sociologist Andrew Cherlin has called “individualised marriage”, where personal growth and self-fulfilment became central expectations.

Types and forms of marriage 🔗

While popular imagination often equates marriage with one man and one woman, the reality across cultures is far more varied.

Monogamy 🔗

Monogamy – the union of two individuals – is the most widely practised and legally recognised form of marriage across the world, particularly in Western societies. In the Indian context, the Hindu Marriage Act of 1955 mandates monogamy for Hindus, Sikhs, Buddhists, and Jains. For Muslims, polygyny (one man married to multiple women) remains legally permissible, though increasingly rare in practice.

Polygamy 🔗

Polygamy involves one person being married to multiple partners. Its most common form is polygyny, practised in some African, Middle Eastern, and Asian cultures. Polyandry – where one woman has multiple husbands – is far rarer but exists among some Himalayan communities, including certain groups in Nepal and India. The Toda community of the Nilgiri Hills and some Tibetan communities have historically practised fraternal polyandry, where brothers share a wife, often for economic reasons such as keeping family land undivided.

Arranged and love marriages 🔗

In arranged marriages, the choice of spouse is made by parents or elders – a practice common in South Asia and the Middle East. Love marriage, based on mutual affection and personal choice, is becoming increasingly widespread globally. In practice, many contemporary families occupy a middle ground – parents may introduce potential matches, but the final decision rests with the individuals concerned.

The shift from procreation to companionship 🔗

Traditionally, biological reproduction was considered the primary purpose of marriage. The anthropologist Kathleen Gough’s widely cited definition centred on the idea that marriage grants children social identity and a legitimate claim to their group’s rights and resources. In a society structured around caste, lineage, and inheritance, this made perfect sense – marriage was the gateway through which legitimate heirs were produced.

But this framing is increasingly incomplete. In modern partnerships, love and emotional compatibility have taken centre stage, with couples viewing marriage primarily as a source of mutual respect, understanding, and personal growth.

The rise of childfree marriages 🔗

One of the most visible markers of this shift is the growing number of couples choosing not to have children. In urban areas, especially among educated young couples, the desire to remain childfree is becoming more common, driven by the tension between traditional family expectations and modern economic realities, lifestyle changes, and growing individualism.

Data from the National Family Health Surveys shows that childlessness among women in India rose from 7% in 2015-16 to 12% in 2019-21, a statistically significant increase. While not all of this is voluntary (infertility remains a factor), a portion reflects deliberate choice. A 2021 Pew Research Centre survey found that 44% of adults aged 18 to 49 cited financial conditions and climate concerns as reasons for choosing not to have children.

For many of these “DINK” (dual income, no kids) couples, marriage is about companionship and mutual growth rather than procreation. Financial pressures, career aspirations, and a desire for personal freedom all play a role. Yet this choice comes with social costs. In a society where children are traditionally seen as a source of support in old age, childfree couples often face societal disapproval and accusations of selfishness.

This trend challenges one of the most deeply held assumptions about marriage – that its fundamental purpose is reproduction. If couples can build fulfilling partnerships without children, then clearly the institution serves broader human needs than biology alone.

Same-sex marriage: the frontier of inclusion 🔗

Perhaps no development has challenged traditional definitions of marriage more than the demand for same-sex marriage rights. The Netherlands became the first country to legalise same-sex marriage in 2001, and since then numerous nations – including Canada, the United States, Germany, Taiwan, and most recently Thailand – have followed.

The Indian context 🔗

The journey toward marriage equality in India has been complex. In 2018, the Supreme Court decriminalised consensual same-sex relations by striking down Section 377 of the Indian Penal Code – a landmark ruling that was celebrated as a victory for dignity and privacy.

However, decriminalisation did not translate into marriage rights. In October 2023, a five-judge Constitution Bench of the Supreme Court unanimously held that there is no fundamental right to marry, and that same-sex marriages cannot be read into the Special Marriage Act, 1954. By a 3:2 majority, the bench further ruled that same-sex couples did not have the right to form civil unions or to adopt children jointly.

While the court declined to grant marriage equality, it did recognise the rights of same-sex couples and affirmed that they are entitled to constitutional protection against discrimination. Chief Justice Chandrachud observed that the right to choose a partner goes to the very root of the right to life and liberty under Article 21 of the Constitution.

Amnesty International described the verdict as a historic missed opportunity, arguing that all people, regardless of sexual orientation or gender identity, should enjoy the full range of human rights, including the right to marry. Scholars writing in The Lancet noted that refusing to recognise same-sex marriage while simultaneously calling for an end to discrimination sends inherently conflicting signals.

The court left the question of marriage equality to Parliament, where it remains unresolved. Meanwhile, the Madras High Court has proposed a concept called the “Deed of Familial Association,” designed to offer same-sex couples some legal protections against harassment and discrimination, without equating their relationships to marriage. It is a partial step, but it reflects the reality that legal frameworks are slowly, if unevenly, adapting.

Adoption and alternative paths to parenthood 🔗

The evolving definition of marriage also intersects with changing ideas about parenthood. Adoption, surrogacy, and assisted reproductive technologies have decoupled parenthood from biological reproduction within marriage. Couples who cannot or choose not to conceive biologically now have multiple pathways to building families.

Under the Central Adoption Resource Authority (CARA) guidelines, married couples, single women, and (in some circumstances) single men can adopt children. However, since the 2023 Supreme Court verdict upheld existing adoption regulations, unmarried couples – including same-sex partners – cannot jointly adopt. This remains a significant barrier for non-traditional families seeking legal recognition.

These developments underline a broader point: marriage is no longer the only route to family formation, and family no longer requires a conventional married couple at its centre. A 2010 study in the United States found that 60% of respondents agreed that if you consider yourself a family, you are a family – a perspective that aligns with an interactionist view of social institutions. Similar shifts in perception, though slower, are visible in Indian urban centres as well.

Why inclusive definitions matter 🔗

The question of how we define marriage is not merely academic. Definitions carry legal weight – they determine who can inherit property, who can make medical decisions for a partner, who can adopt a child, and who qualifies for insurance and pension benefits. When a definition is narrow, it excludes entire categories of people from rights that others take for granted.

Marriage is a cornerstone institution of society in India and, in many cases, a prerequisite for social integration and acceptance. This is precisely why expanding its definition matters. When childfree couples, same-sex partners, and individuals in non-traditional arrangements are denied the legitimacy that marriage confers, the institution itself becomes a tool of exclusion rather than inclusion.

Legal definitions of marriage have expanded in many societies to include same-sex couples, reflecting the understanding that the essential feature of monogamy is exclusivity between two individuals, regardless of gender. The broader trend reflects a decline in marriage rates globally, driven by changing attitudes, increased cohabitation, and delayed marriage due to educational and career pursuits.

The challenge, then, is not whether marriage will survive – it almost certainly will, given its deep roots in human social organisation. The challenge is whether it will evolve fast enough to accommodate the diversity of human relationships that already exist in practice.

The road ahead 🔗

The evolution of marriage is not a story of decline. It is a story of adaptation. From an informal arrangement for managing daily life, to a vehicle for consolidating wealth, to a companionate bond, to a site of personal fulfilment – marriage has continually reinvented itself in response to social, economic, and cultural change.

What is new is the pace and scope of change. Within a single generation, the conversation has expanded to include same-sex unions, voluntary childlessness, live-in partnerships, and blended families. Legal systems are struggling to keep up, but the direction of travel is clear: toward greater individual choice, broader inclusion, and a recognition that no single model of marriage can serve the needs of all people.

For students of public administration and gender studies, these shifts have direct policy implications – from how welfare benefits are structured, to how adoption laws are framed, to how census data captures the diversity of household arrangements. Understanding the evolving meaning of marriage is not just about sociology or anthropology. It is about governance, equity, and the kind of society we want to build.

What do you think? If marriage is no longer primarily about procreation, should legal frameworks be redesigned to focus on partnership rights and responsibilities instead? And as same-sex couples, childfree couples, and cohabiting partners seek recognition, how should the law balance tradition with evolving social realities?
