The Harappan civilisation was as much a hydraulic and town-planning achievement as a craft economy. Examine the archaeological evidence from Mohenjodaro, Dholavira and Lothal in support of this view.

Introduction:

The mature Harappan civilisation (c. 2600–1900 BCE) belongs to the Bronze Age horizon stretching from Mohenjodaro to Lothal. Far from being only a craft economy, it was, as R.S. Sharma argued, a stratified urban order whose hydraulic engineering and town-planning achievements were as visible as its workshops.

Hydraulic engineering:

The Great Bath at Mohenjodaro, with bitumen lining and a sophisticated drainage outlet, is the earliest known public ritual tank in South Asia. Dholavira in Kutch ran a near-total water-harvesting urbanism — sixteen rock-cut reservoirs in a semi-arid landscape — while Lothal's tidal dockyard on the Sabarmati delta enabled controlled navigation through a brick-walled basin.

Town planning:

Cities were laid on a grid with a fortified citadel and a lower town; baked bricks followed a uniform 1:2:4 ratio across the basin; covered drains with manholes ran beneath every street, and houses had latrines connected to public sewers. Dholavira's polished-stone "signboard" of ten characters above its northern gateway suggests civic signage at urban scale.

Craft and trade economy:

Chanhudaro specialised in carnelian beads, Nageshwar in shell ornaments worked from Turbinella pyrum; weights followed a binary-decimal system (1, 2, 4, 8, 16, 32); square steatite seals stamped "Meluhha" goods recovered from Sargonid Mesopotamia and the Persian Gulf entrepôts.

Conclusion:

The Harappan achievement was an integrated urban system, not a sum of crafts. Recent excavations at Rakhigarhi (the largest site) and Sinauli are extending — not overturning — this picture of planned cities resting on a craft and trade hinterland.
