Singh and Kaur Were Designed to Tell You Nothing

Surnames normally leak information. Where a family came from, what an ancestor did, which lineage they belong to. In eighteenth-century Punjab a surname leaked caste, which determined who you could marry, what work you could take and how you would be treated.

Singh and Kaur exist to stop that.

Vaisakhi, 1699

Guru Gobind Singh, the tenth Sikh Guru, founded the Khalsa at Anandpur on Vaisakhi in 1699. Alongside the articles of faith that came with it, he instructed that Sikh men take the name Singh and Sikh women take Kaur.

Singh means lion. Kaur is usually rendered as princess. Both were pre-existing words, and Singh in particular was already in use among Rajput warrior communities, so neither was invented for the purpose.

What was new was the universality. Every initiated Sikh took the same name regardless of birth, which removed the mechanism by which a name announced somebody's position in the caste hierarchy.

Why this was a serious intervention

Caste in this period was not an abstraction, and a caste-marking surname worked as a permanent public label. Dropping it for a shared name attacked the labelling system directly.

The reform also cut in the other direction. High-caste converts gave up a name that had been an asset, which made the equality real rather than symbolic. A community where everyone shares two names cannot rank its members by what they are called.

Kaur does additional work that gets less attention. Women took a name of their own rather than their father's or their husband's, so a Sikh woman's name did not change at marriage and did not identify her by which man she was attached to. That was unusual in 1699 and remains unusual now.

What happened in practice

The system holds imperfectly, which is worth stating plainly.

Many Sikh families use Singh or Kaur as a middle name and carry a clan or village name as well, and those additional names often do carry the caste information the reform was meant to suppress. Jat, Ramgarhia, Arora and similar identifiers circulate widely in matrimonial adverts and community life.

So the reform succeeded at making one name universal and did not eliminate caste from Sikh society. Both of those things are true at once, and accounts that present 1699 as having abolished caste among Sikhs are overstating what a naming rule can do.

The administrative consequence

Singh is now among the most common names on the planet, and it creates real problems for anybody trying to identify a specific person. Immigration systems, particularly in Canada and the United Kingdom, have periodically struggled with the volume, and at one point Canada asked Sikh applicants to use something other than Singh or Kaur, then withdrew the request after objections.

That is the opposite of Thailand's approach, where the law requires every family name to be unique so that a surname identifies exactly one family. Thailand optimised its names for the registry. Guru Gobind Singh optimised his for equality, and the registry has been coping ever since.

A name chosen for what it withholds

Most surnames are records of something. A trade, a place, a father, a landholding. Even names that spread by adoption rather than descent, like Kim in Korea, record what people wanted to be taken for.

Singh and Kaur are the rarer case of a name selected specifically to carry no information about the person holding it. The absence is the design.
