Indus Valley Civilization (Harappan Era)
One of the world's earliest major urban civilisations, spanning northwestern South Asia, renowned for advanced grid town planning, baked brick houses, sophisticated drainage, water reservoirs, and bronze metallurgy.
Established the earliest urban foundations in the Indian subcontinent. Remarkable for lack of monumental palaces or warfare weaponry, focusing instead on civic sanitation, standardized weights, maritime docks, and flourishing trade with Mesopotamia.

c. 2600 BCEUrban planning, fortified settlements, uniform weights and measurements, and extensive trade networks emerge across Indus and Saraswati basins.
Construction of Lothal Dockyard & Dholavira Water Reservoirs
c. 2400 BCEPioneering hydraulic engineering with massive stone-cut water reservoirs at Dholavira and tidal dock basin at Lothal for Persian Gulf trade.
Late Harappan Phase and Urban De-densification
c. 1900 BCEGradual shift away from large urban centres toward rural settlements due to climate shifts, shifting river courses, and changing monsoon patterns.
