If you’ve been searching for a clear, exam-ready breakdown of the types of marriage in anthropology for UPSC, you’ve landed in the right place. This is one of the most frequently asked topics in UPSC Anthropology Paper 1 — questions on this topic have appeared in 1985, 1989, 1991, 2014, and 2017. So let’s not just memorize types. Let’s actually understand them.

Marriage, as anthropologists have studied across cultures, is not one fixed institution. It varies dramatically — in form, function, and who can marry whom. Let’s walk through all the important types, with tribal examples that will make your answers stand out in mains.

What Is Marriage? A Quick Anthropological Reminder

Before jumping into types, remember that defining marriage itself is controversial. The classic 1951 Notes and Queries definition — “a union between a man and a woman such that children born to the woman are recognized as legitimate offspring” — was challenged by Edmund Leach (1960) for being too narrow. Examples like woman-woman marriage among the Nuer of South Sudan, ghost marriage, and polyandry among the Todas of Nilgiris proved that no single definition can be universal.

With that foundation, let’s get into the types.

The Two Universal Types: Monogamy and Polygamy

Anthropologist George Peter Murdock, after surveying hundreds of societies, found that marriage universally falls into two broad categories — monogamy and polygamy. Everything else is a variation or special case.

Monogamy: One Spouse at a Time

Monogamy is the practice of having only one spouse at a time. It is the most legally recognized form of marriage in the modern world. There are two distinct types:

Serial Monogamy means a person can have multiple spouses over a lifetime, but only one at any given time. Divorce followed by remarriage is the classic example. The Semangs of the Malay forest practice serial monogamy. It is also widely seen in the United States, where divorce rates are high but only monogamy is legally permitted.

Non-serial Monogamy is the traditional form where a person has one spouse for life. Divorce is rare. Most Hindu societies in India follow this norm. Tribes practicing monogamy in India include the Andamanese, Khasi, Asura, Angami Nagas, and Gonds. Interestingly, the Ho tribe has been pushed into monogamy due to high bride price requirements.

Polygamy: One Person, Multiple Spouses

Polygamy refers to marriage with more than one person simultaneously. It has three sub-types, and UPSC loves asking about all three with Indian examples.

1. Polygyny — One Husband, Multiple Wives

This is by far the most common form of polygamy across the world. In polygyny, a man has two or more wives at the same time.

Anthropologists have identified several reasons why polygyny exists:
– It provides economic and political advantages by enlarging the kin group
– Polygynous families have more children, meaning more available labor
– Post-partum sex taboos in many societies (where men cannot have sexual relations with nursing mothers) create an incentive for additional wives
– In societies with high male mortality due to warfare, the number of women exceeds men
– When men marry at a later age, older men with more wealth tend to attract multiple wives

Polygyny has two sub-forms:
– Sororal polygyny — where the multiple wives are sisters. Practiced by the Kanikkar and Urail of Kerala.
– Non-sororal polygyny — where the wives are unrelated women.

2. Polyandry — One Wife, Multiple Husbands

Polyandry is far rarer than polygyny. Here, a woman has two or more husbands simultaneously. It exists in two forms:

Why does polyandry exist? The primary reasons include:
– Property considerations — to prevent division of land or resources among brothers
– Sex ratio disparity — a shortage of women, often worsened by female infanticide (as seen among the Todas)
– Polyandry tends to produce fewer children, which can act as a population control mechanism in resource-scarce environments

3. Polygynandry (Group Marriage)

This is the rarest form. Polygynandry involves several men married to several women simultaneously — a group arrangement. It was practiced among the Marquesans of Polynesia and also among the Todas of the Nilgiri Hills and the Khasas of Jaunsar Bawar in India.

Other Special Forms of Marriage

UPSC questions sometimes target these less-common but conceptually important forms:

Fictive Marriage

A legal marriage in which both partners acquire social benefits without establishing a family unit. It exists to claim rights — social, legal, or economic — without the typical domestic arrangement.

Ghost Marriage

A marriage where a living person marries a deceased one, so that the dead person’s lineage continues. The Nuer of South Sudan practice it — if an elder brother dies without fathering children, a younger brother marries his widow on his behalf. The children born are considered the offspring of the deceased brother, not the biological father.

Sologamy (Self-Marriage)

A recent phenomenon where a person formally marries themselves — also called autogamy. While it holds no legal status, it is practiced as a symbolic act of self-love and independence. The trend can be traced to Linda Baker from the US, who married herself in 1993.

Wrapping Up

Understanding the types of marriage is not just about memorizing names and tribes — it’s about seeing how every form solves a problem in that society. Polygyny addresses labor needs. Polyandry prevents land fragmentation. Ghost marriage ensures lineage continuity. When you write your UPSC answer, connect the type to its function. That’s what examiners want to see.
