Indus Valley civilization

  • Around 3BCE, a civilization around the current northwest part of the India, Pakistan region collectively known as the Indus Valley Civilization also known as the Harappan Civilization. It is also called a Harappan Civilization since it was first identified.
  • This region appeared in different phase histories such as Early Harappan which existed from 3000 to 2600 BCE, Mature Harappan from 2600 to 1900 BCE, and Late Harappan raging from 1900 to 1700 BCE.
  • The age of this civilization dates back to the Neolithic villages of 7000 BCE. The urban phase started existing in the Mature Harappan period and declined after that.
  • Charles Mason first visited this civilization in 1826 and Alexander Burnes visited Amri in the place where railway line construction destroyed the archaeological site from Lahore to Multan.
  • The first ASI(Archeological Survey of India) surveyor Alexander Cunningham got a seal from this site. He visited this site earlier in 1853,1856 and in 1875. The importance of this site was not realized until Sir John Marshal’s arrival.
  • Sir John Marshal was the Director-General of ASI and started archaeology research. Mortimer Wheeler in 1940, started research in the Harappan sites. During the India-Pakistan partition during the independence, many sites went to Pakistan.
  • The Indian sites of this Civilization are Kalibangan, Lothal, Rakhi Garhi, and Dholavira, these sites were excavated during that period.

Geographical Area

  • Near 1.5 million square kilometres area in India and Pakistan covered the culture of Indus Civilization.
  • The boundaries of Indus Civilization are Sutkagen-dor in Pakistan-Iran border in the west, Daimabad in Maharastra India in the south, Shortugai in Afghanistan in the North, and Alamgirpur in Uttar Pradesh in the east.
  • Pakistan, Gujarat, Rajasthan, and Haryana are the core areas of Harappa civilization in India.

Early Beginnings

  • Agriculture and animal domestication began earlier in Mehrgarh. There is no evidence related to the continuity of the Neolithic age and Indus Civilization.
  • The development of villages and towns started in the early Harappan phase and they developed urban centres in the Mature Harappan phase.

Town Structure

The major cities of Harrapa time are:

  1. Harappa in Punjab, Mohejo-Daro in Sindh (Pakistan)
  2. Dholavira, Lothal, Surkotada (Gujarat)
  3. Kalibangan, Banawali (Rajasthan)
  4. Rakhigarhi (Haryana)
  • The characteristics of Harappan towns are planned fortification, Geometrical streets, and Lanes, Drainages. The towns are of the grid structure. The well-planned structure of the town gives the impression of the presence of civic authority in the planning of structures of the cities.
  • These people used baked and unbaked bricks and stones for the construction. The house has over one floor, built of mud bricks, and they built drainages of burnt bricks. The site of Mohenjo Daro is a well-planned town built on a platform and has two distinct areas, one is the Citadel and the other one is the lower town.
  • The houses of Mohenjo Daro had bathrooms built with burnt bricks and had a proper drainage system. Some houses had a staircase indicating the existence of multiple floor structures. These houses had multiple rooms and most of the houses had a central courtyard with room around.
  • The citadel area is meant for some special occasions. We identify a warehouse in Mohenjo-Daro. In the courtyard a Great Bath a kind of tank is situated, they lay bricks watertight with gypsum mortar and it had drainage and might be used as either granary or ritual bath.
  • The corridors were present on all four sides and stairs are seen on the northern and southern sides and it was well-paved with several adjacent rooms. Some granary structures are identified.

Agriculture and Animal Domestication in the Indus Valley Civilization

  • Agriculture was the prime source of food and occupation for the Harappans and they cultivated crops like chickpeas, sesame, various millets, wheat, barley, lentils, etc. and they practised a double cropping system.
  • The ploughed field found in Kalibangan shows the Harappan practised Ploughs and also used Canal and Well Irrigation. Pastoralism is yet another occupation practised by Harappans, they domesticated sheep, goats, and fowl also they reared other animals such as buffalo, pigs, elephants, etc.
  • But the Horse was not known to the Harappans. The Harappan cattle are called Zebu, they represent it in Seal. Harappan also ate fish and birds. There are pieces of evidence of boar, gharial, and deer in the Harappan sites.

Craft and Pottery

  • Cubical weights have been discovered from these sites and found in the ratio of weights of 1:2:4:8:16:32. The smallest weight is the 16th ratio weighs 13.63 grams.
  • They also used measuring scales in which one inch was approximately 1.75 cm. Weights made of chert were cubical in shape.
  • They used the binary numbering system (1, 2, 4, 8,16, 32, etc.) that is used for weighing jewellery and precious metals.

Religion Practices

  • The bodies are buried with rich rituals, as burial is found with Pottery, Jewellery, a copper mirror, beads, Goat skeletons, etc., as these people believed in the Afterlife.


  • The seals, weights, and bricks exhibited uniformity that revealed authority and power.

Cultures Existed elsewhere during the Indus Civilization

  • There were large communities of farmers, pastoral people, etc. living throughout the subcontinent from Kashmir to Kanyakumari and Arunachal Pradesh to Gujarat in the same period of the Harappan civilization.
  • These communities are also important as they contribute to Indian Culture.
  • The northern parts of Karnataka and Andra are connected to the Neolithic period and might have a connection with the Indus civilization but there is evidence to prove it.
  • Similarly, Chalcolithic culture is found in Deccan and Western India, and Neolithic culture found in Kashmir, Ganga Valley, and central, eastern India might also have a connection with the Indus Civilization but there is no evidence.
  • As the Indus people are found to be well versed in watercraft they might have connected these areas through waterways.

Decline of the Indus Civilization

  • The Indus Civilization declined after the Mature Harappan in 1900CE.
  • The causes of the decline might be drastic changes in climate, fall of trade with Mesopotamia, the river changing its course or dried or continuous drought The people moved to the Southern and eastern direction of the Indus river regions.

Relationship between Indus Valley Civilization and Tamil Civilization

  • The Indus Civilization is considered the first urbanization and its real origin is still unknown as the Script used in their works is still not deciphered.
  • One cannot ignore that there some many similarities between the Tamil Civilization to the Indus such as graffiti found in Megalithic burial pots of South India and the names of places that have a relation with the Indus.
  • Ancient towns such as Arikamedu, Keezhadi, and Uraiyur town in South India differ from Indus cities.
