Updated on: November 14th, 2023

Indus Valley Civilization, also known as the Harappan Civilization or the Indus Civilization (part of Proto-history), was a Bronze Age civilization in the northwestern regions of South Asia. The Indus Valley Civilization IVC lasted from 3300 BCE to 1300 BCE and in its mature form from 2600 BCE to 1900 BCE. Together with ancient Egypt and Mesopotamia, it was one of three early civilizations of the Near East and South Asia, and of the three, the most widespread, its sites spanning an area stretching from today’s northeast Afghanistan through much of Pakistan and into western and northwestern India.

The Indus Valley Civilization, or Harappan Civilisation, was the first urban civilization in South Asia. It can be concluded that the history of India begins with the birth of the Indus Valley Civilization (IVC).

Indus Valley Civilization

The Indus civilization is also known as the Harappan Civilization after its first site was excavated in what was then the Punjab province of British India and is now in Pakistan. The Indus Civilization was home to the largest of the four ancient urban civilizations of Egypt, Mesopotamia, India and China.

Indus Valley Civilization Notes PDF

  • The IVC flourished in the basins of the Indus River, which flows through the length of Pakistan, along with a system of perennial, mostly monsoon-fed, rivers that once coursed in the vicinity of the seasonal Ghaggar-Hakra river in northwest India and eastern Pakistan.
  • The Indus Valley Civilization is also known as the Harappan Civilization, as Harappa was the first and the most important site of the Indus Valley Civilization.

Indus Valley Civilization Important Points

Some notable Indus Valley Civilization Facts are as follows

  • Indus Valley Civilization in Hindi is called the Sindhu Ghati Sabhyata or Sindhu Civilization
  • The first sites to be discovered were Harappa (discovered by Dr. D.R. Sahani in the year 1921) on the banks of the river Ravi and Mohanjodaro (in 1922 by R.D. Banerjee) on the banks of the river Indus. Sir John Marshall played an important role in both excavations.
  • Indus Valley Civilization forms part of the Protohistory of India and belongs to the Bronze Age.
  • The use of Gold, Silver, Copper and Bronze was there, but the use of Iron was completely unknown.
  • The port cities of the Indus Civilization are Sutkagendor, Balakot, Lothal, Allahdino, and Kuntasi.

Harappan Civilization

The discovery of Harappa and soon after Mohenjodaro was the culmination of work beginning in 1861 with the founding of the Archaeological Survey of India during the British Raj. Sir John Marshall first unearthed Harappan Civilization in 1921. As Harappas was the first site to be discovered, the IVC is also called the Harappan Civilization.

  • Nevertheless, there were earlier, and later cultures in the same area often called Early Harappan and Late Harappan.
  • There are five major urban sites, the most important being: Harappa, Mohenjodaro, Dholavira, Ganeriwala, and Rakhigarhi.

Phases of Indus Valley Civilization

The Indus Valley Civilization is divided into three phases. They are more appropriately named as per Harappan Civilization.

  • Early Harappan Phase (3300 to 2600 BCE): This phase of IVC is related to the Hakra Phase, identified in the Ghaggar-Hakra River Valley, with the earliest examples of the Indus script. This phase is characterized by a centralized authority, urban quality of life, established trade networks and cultivation of crops.
  • Mature Harappan Phase (2600 to 1900 BCE): The second phase of the Indus Valley Civilization is characterized by Kot Diji. The early Harappan communities were turned into large urban centers, like Harappa, Ganeriwala, and Mohenjo-Daro in modern-day Pakistan and Dholavira, Kalibangan, Rakhigarhi, Rupar, and Lothal in modern-day India.
  • Late Harappan Phase (1900 to 1300 BCE): It signifies the gradual decline of the Indus Valley Civilization. However, archaeological data indicates the persistence of the Late Harappan culture till 1000-900 BC.

Architecture and Town Planning of Indus Valley Civilization

Architecture and Town Planning of Harappan Civilization was the most striking feature of the Indus valley civilization. The town planning of the Indus Valley Civilization proves that the IVC people lived a highly civilized and developed life.

  • The people of IVC were the first to build planned cities with a scientific drainage system.
  • For architecture, it can be said that the Indus cities were built on a uniform plan and the town planning was amazing in nature.
  • Life in the Indus Valley Civilization gives the impression of a democratic bourgeois economy like that of ancient Crete.

Facts About Indus Valley Civilization Streets

The streets of IVC were 13 to 34 feet wide and were well lined, straight and cut each other at right angles. The streets and roads divided the city into rectangular blocks. The presence of dustbins proves the presence of good municipal administration. Archaeologists have also discovered the lamp posts at intervals, which suggests the existence of street lights.

Drainage System

The cities of the Indus valley civilization were provided with an excellent closed drainage system. Brick-laid channels flowed through every street.

  • Each house had its own drainage and soak pit which was connected to the public drainage.
  • They were covered and had manholes at intervals for cleaning and clearing purposes.
  • The people of IVC had a perfect underground drainage system.
  • Harappa, Mohenjo-Daro, and the recently partially-excavated Rakhigarhi demonstrate the world’s first known urban sanitation systems.

Granaries of Indus Civilization

They constituted an important part of the Harappan cities and the Indus Valley Civilization. The largest building in Mohenjodaro was the granary which was 45.71 meters long and 15.23 meters wide.

  • In Harappan Civilization, there were a series of brick platforms that formed the base for two rows of 6 granaries each.
  • These granaries safely stored the grains, which were probably collected as revenue or storehouses to be used in emergencies.
  • In the Southern part of Kalibangan, brick platforms have also been found, which is an important feature of the Indus Valley Civilization.

Architecture and Buildings of the Indus Valley Civilization

The houses and other buildings were built on the side of roads by the people of the Indus Valley Civilization.

  • The houses of the IVC were terraced houses made up of burnt bricks. Standardized burnt bricks of ratio 1:2:4 were found in all the sites. No stones were used.
  • Every house had two or more rooms. There were also more than one-storied houses.
  • The houses were designed around an inner courtyard and contained pillared halls, bathrooms, paved floors, kitchens, well etc.
  • There was an excellent system of water supply which was verified by public wells by the side of the streets. Every big house had its own well.
  • The workmen’s quarters are also found. The quality of urban planning suggests efficient municipal governments that placed a high priority on hygiene or religious ritual.

Harappan Civilization demonstrated advanced architecture with dockyards, granaries, warehouses, brick platforms, and protective walls. They also built a dockyard at Lothal.

The Great Bath of the Indus Valley Civilization

The most striking feature in Mohenjodaro is the Great Bath, which is a large quadrangle structure.

  • In the center is a huge swimming pool with the remains of galleries and rooms on all four sides.
  • The Great bath had 8 ft thick outer walls. The water was discharged by a huge drain with a corbelled roof more than 6 ft in depth.
  • There were arrangements for a hot water bath in some rooms.
  • Most scholars agree that this tank would have been used for special religious functions where water was used to purify and renew the well-being of the bathers.

Characteristic features of Harappan cities

There was great uniformity in Harappan town planning. Town planning was based on a grid pattern or chessboard pattern. Streets and lanes intersect at right angles, creating a number of rectangular blocks in the city. The entire city was divided into two major areas; The Citadel and Lower Town.

  • The Citadel was a fortified area with vital public buildings, including granaries and dwellings for the ruling class. The lower town was larger and lay east of the Citadel.
  • The lower town was intended for the common public, while the Citadel and the lower town were separated by an area of ground.

Agricultural Pattern of Indus Valley Civilization

The Indus people were the earliest people to produce cotton. The villages of the Harappan Civilization were situated mostly near the flood plains and produced sufficient foodgrains, such as wheat, barley, rai, peas, sesame, lentil, chickpea and mustard.

  • Millets were found at sites in Gujarat. Animals were also reared on a large scale.
  • Representations on seals and terracotta sculptures indicate that the bull was known, and archaeologists extrapolate shows oxen were also used for plowing.

The IVC also developed some new tools known as plough which was used to dig earth for planting the seeds and turning the soil. Traces of canals have been found at the Harappan site of Shortughai in Afghanistan.

Economy during Indus Valley Civilization

Indus Valley Civilization was a prosperous civilization. The economy of IVC was largely based on agriculture and animal husbandry, supplemented by the exploitation of natural and wild resources.

  • 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 a considerable trade in stone, metal, shell, etc. Metal money was not used and a barter system carried trade.

Agricultural economy

The main crops produced were Wheat, Barley, Rice, Dates, Mustard, and Cotton. The use of wooden ploughshare, well irrigation, dams, and irrigation canals shows the advancement of Harappans in agriculture technology.

  • The Indus people set up a trading colony in northern Afghanistan, which facilitated trade with Central Asia.
  • They also carried commerce with those in the land of the Tigris and the Euphrates.

Manufacturing in IVC

A large number of terracotta articles show that it was used by common people. Harappans were the first to use silver in the world, and the people did not use iron but used Copper, bronze, silver, and gold. Owing to this, the Harappan people were good at metallurgy and producing alloys. The Indus Valley people were an expert in bead-making jewelry.


The Harappans used Red and Black pottery (redware painted with black designs) and also knew the use of Potter’s wheel with ease. It shows the expertise of Harappans in pottery making e.g., Glazed pottery, incised pottery, perforated pottery, etc. Harappans produced their own characteristic pottery, which was glossy and shining.

Trade in Indus Valley Civilization

Harappans had trade with Mesopotamia (Sumeria), Central Asia, Persia, Afghanistan Makan (Oman), and Dilmun (Bahrain). Trade in the Indus Valley Civilization was through the barter system.

  • Trade shows the advanced trade relation of the Harappan civilization with other parts of India as well as also with other contemporary civilizations.
  • Export items included Teak ( obtained from Gujrat), Amazonite (Hirapuri, GJ), Slate (Kangra), Lead (Kashmir and South India), and Copper (from Baluchistan).
  • The import items include Jade (from Central Asia), Turquoise (from Khorasan), Lapis Lazuli, Gold, Silver, and Tin ( from Afghanistan), Gold was also obtained from Iran and Kolar mines in Karnataka and Steatite (Iran).

Weights and Measures

The weights followed a binary system of 1, 2, 8, 16, 32 to 64, 160, 320, 640, 1600, 3200, and so on. Weights were made of chert, limestone, and steatite and were generally cubical. The standardization and accuracy of weights and measures throughout the IVC were remarkable.


Harappan seals are the greatest artistic creation and were used to mark ownership of property and in trade. They were made up of Steatite (soft stone) and were half an inch to 2.5 inches. The seals were generally square and rectangular, with carved animals and inscriptions. The humpless bull is the most used animal in seals.

Religion during Indus Valley Civilization

In Harappa, numerous terracotta figurines of women have been found. The Harappans, therefore, looked upon the earth as a fertility goddess and worshiped her in the same manner as the Egyptians worshiped 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 a buffalo below his throne. At his feet appear two deer. The depicted god is identified as Pashupati Mahadeva. T
  • The people of the Indus Valley Civilization also worshiped 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.
  • The absence of any palace or temple despite structures like granaries and public baths led historians to believe that the Indus Valley society was an egalitarian one.

Decline of Indus Valley Civilization

The Indus Valley Civilization declined around 1800 BCE. The reasons behind the demise of Civilization are still debated.

  • Many scholars believe that the collapse of the Indus Valley Civilization was caused by climate change.
  • Some experts believe the drying of the Saraswati River, which began around 1900 BCE, was the main cause of climate change, while others conclude that a great flood struck the area.
  • Many scholars argue that changes in river patterns caused the large civilization to break up into smaller communities called late Harappan cultures.
  • Another disastrous change in the Harappan climate might have been eastward-moving monsoons or winds that bring heavy rains.
