Indus Valley Civilisation Notes Free: Introduction, Town Planning, Religion, Decline


  • The history of India begins with the birth of the Indus Valley Civilization (IVC), also known as Harappan Civilization.
  • It flourished around 2,500 BC, in the western part of South Asia, in contemporary Pakistan and Western India.
  • The Indus Valley was home to the largest of the four ancient urban civilizations of Egypt, Mesopotamia, India and China.
  • In 1920s, the Archaeological Department of India carried out excavations in the Indus valley wherein the ruins of the two old cities, viz. Mohenjodaro and Harappa were unearthed.
  • In 1924, John Marshall, Director-General of the ASI, announced the discovery of a new civilisation in the Indus valley to the world.

Phases of IVC

  • Three phases of IVC are:
    • the Early Harappan Phase from 3300 to 2600 BCE,
    • the Mature Harappan Phase from 2600 to 1900 BCE, and
    • the Late Harappan Phase from 1900 to 1300 BCE.
  • The Early Harappan Phase is related to the Hakra Phase, identified in the Ghaggar-Hakra River Valley.
  • The earliest examples of the Indus script date back to 3000 BC.
  • This phase stands characterized by centralized authority and an increasingly urban quality of life.
  • Trade networks had been established and there are also evidences of the cultivation of crops. Peas, sesame seeds, dates, cotton, etc, were grown during that time.
  • Kot Diji represents the phase leading up to Mature Harappan Phase.
  • By 2600 BC, the Indus Valley Civilization had entered into a mature stage.
  • The early Harappan communities were turning into large urban centers, like Harappa and Mohenjodaro in Pakistan and Lothal in India.
  • The signs of a gradual decline of the Indus River Valley Civilization are believed to have started around 1800 BC and by 1700 BC, most of the cities were abandoned.
  • However, one can see the various elements of the Ancient Indus Valley Civilization in later cultures.
  • Archaeological data indicates the persistence of the Late Harappan culture till 1000-900 BC.

Town Planning and Structures of Indus Valley Civilisation

  • The Harappan culture was distinguished by its system of town planning.
  • Harappa and Mohenjodaro each had its own citadel or acropolis, which was possibly occupied by members of the ruling class.
  • Below the citadel in each city lay a lower town containing brick houses, which were inhabited by the common people.
  • The remarkable thing about the arrangement of the houses in the cities is that they followed the grid system.
  • Granaries constituted an important part of the Harappan cities.
  • The use of burnt bricks in the Harappan cities is remarkable, because in the contemporary buildings of Egypt mainly dried bricks were used.
  • The drainage system of Mohenjodaro was very impressive.
  • In almost all cities every big or small house had its own courtyard and bathroom.
  • In Kalibangan many houses had their wells.
  • At sites such as Dholavira and Lothal (Gujarat), the entire settlement was fortified, and sections within the town were also separated by walls.


  • The Harappan villages, mostly situated near the flood plains, produced sufficient foodgrains.
  • Wheat, barley, rai, peas, sesame, lentil, chickpea and mustard were produced. Millets are also found from sites in Gujarat. While rice uses were relatively rare.
  • The Indus people were the earliest people to produce cotton.
  • While the prevalence of agriculture is indicated by finds of grain, it is more difficult to reconstruct actual agricultural practices.
  • Representations on seals and terracotta sculpture indicate that the bull was known, and archaeologists extrapolate shows oxen were also used for ploughing.
  • Most Harappan sites are located in semi-arid lands, where irrigation was probably required for agriculture.
  • Traces of canals have been found at the Harappan site of Shortughai in Afghanistan, but not in Punjab or Sindh.
  • Although the Harappans practised agriculture, animals were also reared on a large scale.
  • Evidence of the horse comes from a superficial level of Mohenjodaro and from a doubtful terracotta figurine from Lothal. In any case the Harappan culture was not horse centred.

Economy of Indus Valley

  • The importance of trade in the life of the Indus people is witnessed by the presence of numerous seals, uniform script and regulated weights and measures in a wide area.
  • The Harappans carried on considerable trade in stone, metal, shell, etc.
  • Metal money was not used and trade was carried by barter system.
  • They practised navigation on the coast of the Arabian Sea.
  • They had set up a trading colony in northern Afghanistan which evidently facilitated trade with Central Asia.
  • They also carried commerce with those in the land of the Tigris and the Euphrates.
  • The Harappans carried on long distance trade in lapis lazuli; which may have contributed to the social prestige of the ruling class.


  • In Harappa numerous terracotta figurines of women have been found. In one figurine a plant is shown growing out of the embryo of a woman.
  • The Harappans, therefore, looked upon the earth as a fertility goddess and worshipped her in the same manner as the Egyptians worshipped the Nile goddess Isis.
  • The male deity is represented on a seal with three horned heads, represented in the sitting posture of a yogi.
  • This god is surrounded by an elephant, a tiger, a rhinoceros, and has a buffalo below his throne. At his feet appear two deer.The depicted god is identified as Pushupati Mahadeva.
  • Numerous symbols of the phallus and female sex organs made of stone have been found.
  • The people of the Indus region also worshipped trees and Animals.
  • The most important of them is the one horned unicorn which may be identified with the rhinoceros and the next important was the humped bull.
  • Amulets have also been found in large numbers.

Decline of the Indus Valley Civilization

  • The IVC declined around 1800 BCE but the actual reasons behind its demise are stilldebated.
  • One theory claims that Indo-European tribe i.e. Aryans invaded and conquered the IVC ( Indus Valley Civilisation).
    • In later cultures various elements of the IVC are found which suggest that civilization did not disappear suddenly due to an invasion.
  • On the other hand, many scholars believe natural factors are behind the decline of the IVC.
    • The natural factors could be geological and climatic.
    • It is believed that the Indus Valley region experienced several tectonic disturbances which causes earthquakes. Which also changed courses of rivers or dried them up.
    • Another natural reason might be changes in patterns of rainfall.
  • There could be also dramatic shifts in the river courses, which might have brought floods to the food producing areas.
  • Due to combination of these natural causes there was a slow but inevitable collapse of IVC.
