12. UPSC Relevance

Prelims: Questions are frequently asked on chronology, site locations, the Great Bath, standardised weights and bricks, the undeciphered script, trade with Mesopotamia, the Pashupati seal, and the discovery history. The names of excavators (Daya Ram Sahni, Rakhal Das Banerji, John Marshall, R.E.M. Wheeler) and the year 1924 (announcement of the civilisation) are important.

GS Paper 1 (Ancient History and Indian Heritage): Questions on map-based site identification, urban planning, economy, the Aryan debate, and the archaeogenetics research at Rakhigarhi are important.

GS Paper 1 (Art and Culture): Harappan art — seals, Dancing Girl, pottery, beads — appears in questions on India's ancient artistic heritage.

Optional History: Detailed questions on sources (archaeological methods, stratigraphy), economy, social structure, religion, writing, trade networks, and decline theories are standard.

Current Affairs Angles: Dholavira was inscribed on the UNESCO World Heritage List in 2021. Rakhigarhi's DNA study (2019, Cell journal) is a landmark finding. Both are recurring UPSC topics.

Indicative Previous Year Questions:

Discuss the main features of town planning in the Harappan Civilisation. (Mains)
The decline of the Harappan Civilisation: factors and analysis. (Mains)
Which Harappan site is known for its dockyard? (Prelims)

One-Page Revision Summary

Also known as: Indus Valley Civilisation; Indus-Sarasvati Civilisation

Period: 6000 BCE (Early) → 2600 BCE (Mature urban) → 1900 BCE (Decline begins) → 1300 BCE (Late end)

Spread: Afghanistan to Maharashtra; Pakistan (Punjab, Sindh, Baluchistan) to India (Gujarat, Haryana, Rajasthan, UP)

Sites: More than 2,000 discovered; major five: Rakhigarhi (largest, 550 ha), Mohenjodaro (125 ha, Great Bath), Harappa (first found, 1920-21), Dholavira (three zones, reservoirs, UNESCO 2021), Ganweriwala

Town Planning: Grid roads; citadel + lower town; standardised bricks (4:2:1 ratio); complete drainage system; approximately 700 wells (Mohenjodaro)

Economy: Wheat, barley, cotton (first in Eurasia); cattle, sheep; bronze/copper crafts; bead-making; maritime trade with Mesopotamia (Meluhha)

Trade: Seals + chert weights (binary-decimal); Lothal dock (217 m x 36 m); Oman copper (nickel trace); carnelian beads at Susa (Iran)

Society: Relatively egalitarian; same construction quality for all houses; no clear monarchy; no mass grave wealth

Religion: Mother goddess (terracotta), Pashupati Seal (proto-Shiva), fire altars (Kalibangan/Lothal), Great Bath (ritual bathing)

Script: 375-400 signs; right to left; undeciphered; longest inscription approximately 26 signs

Art: Dancing Girl (bronze, 10.8 cm, Mohenjodaro); Pashupati Seal; standardised pottery; carnelian beads; ivory comb

Decline (c. 1900 BCE): Climate change + Sarasvati drying (two agreed factors); Aryan invasion theory disproven by Dales (1964) and Rakhigarhi DNA study (2019); ecological degradation; internal fragmentation

Discovery: 1924 — John Marshall (DG, ASI) announced the civilisation; first excavators — Daya Ram Sahni at Harappa, Rakhal Das Banerji at Mohenjodaro
