The Indus Valley Civilization was a Bronze Age civilization located in the western region of South Asia, and spread over what are now Pakistan, northwest India, and eastern Afghanistan. Flourishing in the Indus River basin, the civilization extended east into the Ghaggar-Hakra River valley and the upper reaches Ganges-Yamuna Doab; it extended west to the Makran coast of Balochistan and north to northeastern Afghanistan. The civilization was spread over some 1,260,000 km², making it the largest ancient civilization. The Indus Valley is one of the world's earliest urban... civilizations, along with its contemporaries, Mesopotamia and Ancient Egypt. At its peak, the Indus Civilization may have had a population of well over five million. Inhabitants of the ancient Indus river valley developed new techniques in metallurgy and handicraft and produced copper, bronze, lead, and tin. The civilization is noted for its cities built of brick, roadside drainage system, and multistoried houses.
