Indus Civilization

The Indus Valley Civilization (IVC), also known as the Harappan Civilization, is a Bronze Age society that flourished in the northwestern regions of South Asia from approximately 3300 BCE to 1300 BCE. Its mature phase lasted from 2600 BCE to 1900 BCE. It was one of the three early civilizations of the Old World, alongside Mesopotamia and Ancient Egypt.

Geographical Extent

The civilization covered a vast area spanning parts of modern-day Pakistan, northwest India, and northeast Afghanistan. Its northernmost site was Shortugai in Afghanistan, while the southernmost was Daimabad in Maharashtra. To the west, it extended to Sutkagen Dor on the Makran coast near the Iran border, and to the east, it reached Alamgirpur in Uttar Pradesh.

Urban Planning and Architecture

The Harappan cities are famous for their grid system of town planning, where streets cut each other at right angles. They utilized burnt bricks for construction, a unique feature compared to contemporary civilizations that used mud bricks.

Key Urban Features

• Cities were divided into two parts: the Citadel (western side, smaller, elevated) and the Lower Town (eastern side, larger, residential).
• The Citadel housed public buildings, religious structures, and granaries.
• Houses featured efficient drainage systems, with street drains covered by stone slabs or bricks.
• Drains were equipped with manholes for periodic cleaning.
• The Great Bath, located at Mohenjo-daro, is the most famous public tank, built with watertight bricks coated with bitumen.
• Granaries found at Harappa and Mohenjo-daro served as storage facilities for surplus grain.
• Lothal functioned as a major port city with a dockyard, facilitating maritime trade.

Economic Life

The economy was based on a combination of agriculture, animal husbandry, and robust internal and external trade.

Agriculture and Trade

• Main crops included wheat, barley, peas, mustard, sesamum, and cotton.
• Harappans were the first to produce cotton in the world.
• Domesticated animals included cattle, sheep, goats, buffaloes, and camels.
• Seals made of steatite have been discovered across thousands of specimens, often depicting animals like the unicorn, bull, or elephant.
• Trade networks extended to Mesopotamia, with Harappan seals found in regions like Sumer.
• Weights and measures were highly standardized, typically made of chert, in binary and decimal multiples.

Social and Religious Life

While no clear evidence of a powerful ruling class like kings or priests exists, the society was likely organized by a merchant or priestly elite.

Beliefs and Artifacts

• Worship of the Mother Goddess is evidenced by numerous terracotta figurines.
• The Pashupati Seal depicts a figure seated in a yogic posture, surrounded by animals, often identified as a prototype of Lord Shiva.
• Worship of trees, stones, and animals was prevalent.
• No temples have been discovered at any IVC site.
• The Dancing Girl, a bronze statue from Mohenjo-daro, showcases advanced metallurgy.
• The Bearded Man, a steatite sculpture, represents a priest-king.

Major Sites and Discoveries

• Harappa (Punjab, Pakistan): First site discovered in 1921 by Daya Ram Sahni.
• Mohenjo-daro (Sindh, Pakistan): Discovered in 1922 by R.D. Banerji; site of the Great Bath and the Dancing Girl.
• Chanhudaro (Sindh, Pakistan): Known for bead-making factories and the absence of a citadel.
• Lothal (Gujarat, India): Famous for the man-made dockyard and evidence of rice husk.
• Kalibangan (Rajasthan, India): Known for fire altars and evidence of a ploughed field.
• Dholavira (Gujarat, India): Renowned for the unique division of the city into three parts and advanced water management systems.
• Banawali (Haryana, India): Notable for a terracotta model of a plough.
• Surkotada (Gujarat, India): The only site where actual remains of a horse have been claimed.

Decline of the Civilization

The decline of the IVC around 1900 BCE is attributed to several factors rather than a single event. Theories include environmental changes like the drying up of the Saraswati River, tectonic shifts causing floods or earthquakes, recurring droughts, or the collapse of trade with Mesopotamia. The influx of new populations or internal social decay are also debated as contributory factors.

Miscellaneous Facts

• The script of the Indus people remains undeciphered. It is written in a boustrophedon style, meaning from right to left and then left to right.
• The civilization is classified as proto-historic because, although a script exists, it cannot be read. Iron was unknown to the Harappans; their tools were made of copper, bronze, stone, and bone.
• Beads were crafted from carnelian, lapis lazuli, and agate.

The Harappan cities utilized a standard grid layout, which is considered a significant achievement in human history. The society was generally peaceful, as evidenced by the scarcity of weapons and defensive military structures compared to other civilizations of that time.
