Because it was named several times over, by different people at different stages of discovery — and each name records what was known at the moment it was coined.
| Name | Where it comes from | What it claims — and what it is worth |
|---|---|---|
| Harappan civilisation | From Harappa, the first city of this civilisation to be excavated, in 1920–21; its inhabitants are therefore called Harappans | Neutral and safe. It names a site, not a region, so it cannot be proved wrong by a new discovery — which is why archaeologists like it |
| Indus civilisation | From the Indus (Sindhu) River, along which Harappa and Mohenjo-daro were found | True but partial. Many sites are nowhere near the Indus |
| Indus Valley civilisation | The same river, plus ‘valley’ — the term used when only Indus sites were known | Obsolete. The map (Fig. 6.3) shows the civilisation “extended much beyond the Indus region”. The book deliberately does not use it |
| Indus-Sarasvatī / Sindhu-Sarasvatī civilisation | Both river systems together — the Indus and the Sarasvatī (today's Ghaggar-Hakra) | The most accurate. The Sarasvatī basin alone holds two major cities (Rakhigarhi, Ganweriwala), several smaller ones (Farmana, Kalibangan) and towns (Bhirrana, Banawali) — plus the highest density of sites on the map |
The significance — three things the names teach us.
- Names are dated evidence, like anything else. ‘Indus Valley’ tells you what people knew in the 1920s, not what is true.
- Every name makes a hidden claim. Say ‘Indus’ and you have quietly said the civilisation belonged to one river. Say ‘Indus-Sarasvatī’ and you have restored the other half of it.
- Knowledge grows, so names must be revised. “Such discoveries continue even today!” — Rakhigarhi, Dholavira, Bhirrana and Lothal were all unknown when the first name was given.
