Kalibangan: Rajasthan's Harappan City
Discovery and Excavation
Kalibangan is located on the left bank of the ancient Ghaggar River (presently a dry seasonal riverbed) in Hanumangarh district, near the Haryana border.
- First identified: A. Ghosh (Director General, ASI) in 1952 during a systematic surface survey
- Excavated: B.B. Lal and B.K. Thapar (ASI), 1961–69 — the most comprehensive excavation of any Rajasthan prehistoric site
- Site extent: Approximately 300 × 120 metres (lower town) + 240 × 120 metres (citadel mound); much of the site is unexcavated
Two Phases of Occupation
Kalibangan's stratigraphy shows two distinct cultural phases:
Pre-Harappan Phase (c. 2900–2550 BCE)
- Mud-brick houses in irregular layouts
- Handmade pottery with geometric designs
- World's oldest ploughed field (c. 2800 BCE): A field south of the settlement shows a grid of furrows — some oriented northeast-southwest and others southeast-northwest — preserved under the Harappan deposits. The criss-cross pattern matches the double-ploughing practice still used in the region today. This is the earliest direct evidence of ploughed agriculture anywhere in the world.
- No writing, no standardised weights and measures
Mature Harappan Phase (c. 2550–1900 BCE)
The settlement was reorganised on the Harappan urban plan with two distinct zones:
| Feature | Kalibangan | Mohenjo-daro / Harappa |
|---|---|---|
| Citadel fortification | Yes — mud brick | Yes |
| Lower town fortification | Yes — unique to Kalibangan | No |
| Fire altars on citadel | Yes — 5–6 platforms with fire pits | Absent |
| Great Bath equivalent | None found | Present at Mohenjo-daro |
| Streets grid (lower town) | Yes | Yes |
| Drains | Yes | Yes |
| Burnt brick | Yes (Harappan phase) | Yes |
| Ploughed field evidence | Pre-Harappan ploughed field | Absent |
| Seal script | Yes (Harappan script) | Yes |

Kalibangan's Unique Diagnostic Features
Double fortification: Both the citadel (western mound) and the lower town (eastern mound) were independently fortified with mud-brick walls. This is found nowhere else in the Harappan world — not at Mohenjo-daro, Harappa, Dholavira, or Rakhigarhi.
Fire altars (yajña-vedikas): The citadel at Kalibangan contains a row of 5–6 brick platforms, each with a fire pit (some with animal bones and ash). These are interpreted as ritual fire altars. Their presence at the Harappan-era citadel has been cited as evidence connecting Harappan ritual practice to later Vedic fire-sacrifice traditions — though this interpretation remains debated in academic scholarship.
Absence of a Great Bath: Unlike Mohenjo-daro (famous for its Great Bath), Kalibangan shows no large communal bathing structure, though individual bathrooms with brick floors and drains were found in houses.
Harappan script seals: Standard Harappan-script inscribed seals and sealings confirm Kalibangan was part of the fully literate Harappan urban network.
Pre-Harappan ploughed field: The field preserved under the Mature Harappan deposits is geographically dated to c. 2800 BCE — the single most internationally cited archaeological finding from Rajasthan.
Abandonment
Kalibangan was abandoned c. 1900 BCE, contemporaneous with the collapse of other mature Harappan cities. The most widely accepted explanation is the drying of the Ghaggar-Hakra river (the ancient Saraswati), which removed the agricultural water supply that sustained the city.
