The Indus Valley civilization was a Bronze Age civilization [3300-1300BCE, mature period 2600-1900BCE], located mostly in the western part of the Indian subcontinent. It flourished around the Indus river basin. Primarily centered along the Indus river and the Punjab region, the civilization sprawled into the Ghaggar-Hakra river valley and the Ganges-Yamuna doab, encompassing most of what is now Pakistan, as well as extending up to the western most state of modern-day India, south eastern Afghanistan, the eastern part of Baluchistan and Iran.
Harappa was the first of its cities to be excavated in the 1920’s. Presently in Pakistan, it was at that time in the Punjab province of British India. The mature phase of this civilization was known as the Harappan civilization. With it came the discovery of another site which is Mohenjo-Daro, a UNESCO World heritage site.
This civilization was remarkable for its stability [nearly a thousand years]. The people in this civilization were among the first to develop a system of uniform weights and measures. Their smallest division was marked on an ivory scale found in Lothal. It was the smallest ever recorded in the Bronze Age [1.704mm].
All their cities were well planned. The streets were at right angles with an elaborate system of covered drains. They were built with baked bricks of the same size. The discovery of kilns to make bricks support the fact that burnt bricks were used extensively. Besides houses, there were big buildings like the Great bath at Mohenjo-Daro and the vast granaries. Another invention is an instrument, which was used to measure the horizon and the tidal lock. They also evolved new techniques in metallurgy producing copper, bronze, lead and tin. The people of the Indus valley civilization, from the early Harappan periods, had knowledge of prodentistry. The oldest evidence of drilling teeth of humans in a living person was found in Mehrgarh. A touchstone probably used to test the purity of gold was found in Banawali.
The seals or pictures point to the use of domesticated animals, which include camels, goats, water buffaloes and fowls. The Harappans cultivated wheat, barley, peas and sesamum. They were the first to grow cotton and prepare clothes from it. Trade was a major activity. The lapis lazuli used to paint pots was another invention of theirs.
The economy of the Indus valley civilization appears to have depended on trade. Advances in transport technology facilitated it. They used bullock carts still seen throughout South Asia, as well as boats. The boats were small and flat-bottomed. A docking facility at the coastal city of Lothal, with a discovery of a massive, dredged canal, indicate that they used extensive canal network to irrigate the cultivable land..
Regular trade seemed to have linked the Harappan and Mesopotamian civilizations. This trade became feasible with the innovative development of plank-built watercraft. The Indus valley civilization area shows ceramic similarities with southern Turkmenistan and northern Iran.
A sophisticated and technologically advanced culture was evident in the Indus valley. The homes had water drawn from wells. They were not only the first urban centers. But also the world’s first known urban sanitation systems. The wastewater was channelized through the drains.
The art and culture of Mohenjo-Daro’: Various sculptures, seals, pottery, gold jewelry and anatomically detailed figurines in terracotta, bronze and steatite have been found. They also found a number of gold, terracotta and stone figurines of girls in dancing poses. The terracotta figurines include cows, bears, monkeys and dogs.
The Harappans worshipped Gods and Goddesses in male and female forms, evolved some rituals and ceremonies too. No monumental sculpture survives, but a large number of figurines have been discovered, including a steatite bust of a man thought to be a priest and a striking bronze dancing girl. Countless terracotta statues of the Mother Goddess have been discovered suggesting that she was worshipped in nearly every home.
By about 1700BC, the Harappan culture was on the decline. This decline has several reasons. The repeated flooding of towns located on the riverbanks and the ecological changes that harmed agriculture. When the initial migrations of the Aryan people into India began about 1500BC the developed Harappan, culture had already been virtually wiped out.
