Why it matters

Chapter overview

Ancient India spans from the Bronze Age Harappan cities, through the pastoral-then-settled Vedic age, to the great pan-subcontinental empires of the Mauryas and Guptas. This topic covers Harappan urban planning and its key sites, the Early-to-Later Vedic transition, the rise and administration of the Mauryan empire under Chandragupta and Ashoka, and the Gupta 'Golden Age' through to Harshavardhana — the backbone of UPSC's ancient history questions.

1Harappan Civilisation & Urban Planning

The Bronze Age Indus/Harappan Civilisation (c. 2600-1900 BCE) built some of the world's earliest planned cities, with grid-pattern streets, covered drainage and standout structures like Mohenjo-daro's Great Bath.

Learning Objectives

State the approximate mature phase of the Harappan Civilisation (2600-1900 BCE) and its Bronze Age character.
Identify at least four major Harappan sites and one distinguishing feature of each.
Describe the grid-pattern town planning and drainage system common across Harappan cities.
State that the Harappan script remains undeciphered, unlike contemporary Mesopotamian cuneiform.

Key Terms

Great BathA large, brick-built, water-tight public bathing tank at Mohenjo-daro, believed to have had ritual significance.

Grid Pattern PlanningHarappan cities were laid out on a grid, with streets intersecting at right angles and separate 'citadel' (upper town) and 'lower town' zones.

Dockyard (Lothal)A brick-lined basin at Lothal, Gujarat, interpreted as a tidal dock connecting the settlement to maritime trade routes.

Great GranaryLarge brick structures found at Harappa and Mohenjo-daro, believed to have stored surplus grain, indicating organised food management.

The **Harappan (Indus Valley) Civilisation** was a Bronze Age culture whose mature urban phase ran roughly from 2600 to 1900 BCE, spread across present-day Pakistan and north-west India — one of the world's earliest and largest urban civilisations, contemporaneous with Egypt and Mesopotamia.

Key sites and their standout features

Mohenjo-daro (Sindh, Pakistan) — the Great Bath, a large granary, and the best-preserved example of Harappan grid-pattern planning.
Harappa (Punjab, Pakistan) — the type-site that gave the civilisation its name; twin mounds, granaries, and workmen's quarters.
Lothal (Gujarat) — a brick-built tidal dockyard, evidence of maritime trade reaching as far as Mesopotamia; also a bead-making centre.
Dholavira (Gujarat) — sophisticated water conservation/harvesting system with reservoirs, unique among Harappan sites; a three-part city division.
Kalibangan (Rajasthan) — evidence of a ploughed agricultural field and fire altars.
Rakhigarhi (Haryana) — currently the largest known Harappan site by area.

Urban planning

Harappan cities followed a **grid pattern**, with a raised 'citadel' (administrative/religious structures) separate from the 'lower town' (residential areas), covered underground drains along every street, and standardised, kiln-fired bricks in a consistent 4:2:1 ratio.

Common MistakeThe Harappan script, found on seals, remains UNDECIPHERED to this day, unlike Mesopotamian cuneiform or Egyptian hieroglyphs — a frequently tested distinguishing fact.

No large temple structures have been definitively identified at any Harappan site — unlike contemporary Mesopotamian or Egyptian civilisations, religious practice appears to have centred on seals (possibly depicting a proto-Shiva 'Pashupati'), terracotta figurines, and fire altars rather than monumental temples.
