Indus Valley civilisation sites for UPSC map practice

Almost every question on the Indus Valley is a map question wearing a history costume. It asks where a site is, or what a particular town was known for, and those are the same kind of knowledge: a place attached to a fact. Once the fifteen sites sit on a mental map, the topic stops producing surprises.

The other useful thing about starting from the map is that it explains the civilisation itself. The cities are spread across a plain drained by a river system that has since moved, and the pattern of that spread tells you more about how the Harappans lived than any single excavation does.

What the questions actually ask

There are two shapes. The first is locational: which modern state or country is this site in, and which site is furthest in a given direction. The second is functional: which town had the great bath, the dockyard, the ploughed field, the fire altars.

A third shape has become more common, and it is a combination of the two. A statement names a site, places it in the wrong province, and credits it with a feature that belongs to a neighbour. Two errors in one sentence, and the statement is false if either is wrong.

The sites, one line each

Four of these are in Pakistan and eleven in India, which is the single most useful division to hold, because the commonest mistake is to assume that a civilisation named after Harappa must be centred in the country that inherited the name.

The four corners

The extent of the civilisation is usually described by its four extremes, and those four names do most of the work in a locational question.

The distances are worth holding as a pair of numbers rather than a sentence: roughly fifteen hundred kilometres from north to south, and eleven hundred from east to west. That is a larger area than either Egypt or Mesopotamia covered, and it is the reason the archaeology is spread across seven modern Indian states and one neighbouring country.

What the cities had in common

The uniformity is the striking thing. Streets were laid out on a grid aligned roughly to the cardinal directions. Houses were built of kiln-fired brick in a standard ratio of one to two to four, so a brick from one city would fit a wall in another. Drains ran under the streets and were covered with removable slabs, and the larger houses had bathing rooms with sloped floors and outlets into the drain.

Weights follow a binary series, doubling from one to two to four and so on, and the same system appears at every major site. Seals carry a script that is still undeciphered and a humped bull, a unicorn-like animal, and a seated figure that is often read as a prototype of Shiva. None of this proves a single government, but it does show a shared set of standards across a very large area.

What the cities do not have is equally telling. There is no structure that is unambiguously a temple, no palace that dwarfs the houses around it, and no royal burial with treasure. The largest buildings are public rather than royal: the great bath at Mohenjo-daro, the granaries, the reservoirs at Dholavira. Whatever held the cities together, it did not advertise itself in the way that Egypt advertised its pharaohs.

The associations that get swapped

Dholavira and Rakhigarhi

Those last two sites are the ones most likely to appear in a question with a current-affairs flavour, because both have produced work in the last decade that changed how the civilisation is described.

Dholavira was inscribed as a World Heritage Site in 2021, and the citation leans on its water engineering. The city sits on an island in the Rann of Kutch with no perennial river, and it survived by capturing the seasonal flow in a series of reservoirs, some of them cut into the rock and lined. The signboard, ten large characters set in a wooden frame above the north gate, is the longest inscription of Harappan script found anywhere, and the fact that it was displayed at a gateway suggests the writing was meant to be read by people arriving.

Rakhigarhi has been excavated since the 1990s and is the largest Harappan site in India, with the usual qualification that "largest" depends on whether you count the full spread of mounds or only the walled area. Its importance now is the cemetery. A skeleton from the site produced the first ancient DNA from a Harappan individual, and the study published in 2019 found no trace of Steppe pastoralist ancestry. That does not settle the debate about migration, but it is the hardest evidence yet that the people who built the cities were not simply replaced by later arrivals.

How to hold the map

Draw it once, by hand, and put five things on the paper: the four corners, the four sites in Pakistan along the Indus and the Ravi, the Gujarat cluster of Dholavira, Lothal and Surkotada, the Haryana cluster of Rakhigarhi and Banawali, and the two northern sites of Ropar and Manda. Everything else can be hung on that frame later.

Then test the frame rather than the list. Cover the table and ask yourself which site is furthest east, which has no citadel, which produced the plough model, and which produced the field. The answers are all on the map if the map is there.

The map also connects forward. The cities of the Gangetic plain that come next sit on the same rivers, which is why India map practice is worth doing alongside this topic. The religious history that follows begins with the Buddhist councils, and the material culture of the Harappans is the first layer under the art and culture of the subcontinent.
