Major Harappan Centers & Decline

3. Characteristics of Major Harappan Centers

Hundreds of Harappan sites have been excavated, but a few stand out as major urban centers or specialized industrial hubs, providing key archaeological artifacts.

Harappa (Punjab, Pakistan)

• Location: Situated on the banks of the river Ravi.
• First Discovered: Excavated by Daya Ram Sahni in 1921. Being the first discovered site, the civilization is named after it.
• Key Findings:
  • A row of 6 Granaries outside the citadel.
  • Circular brick platforms used for threshing grain.
  • Workmen's quarters indicating a structured labor class.
  • A virgin goddess seal (female figure with a plant growing out of her womb).
  • Two prominent stone sculptures: one depicting a red sandstone naked male torso, and another of a dancing male in grey stone.

Mohenjo-Daro (Sindh, Pakistan)

• Location: Situated on the banks of the river Indus. The name literally translates to "Mound of the Dead."
• First Discovered: Excavated by R.D. Banerjee in 1922. It is the largest known Harappan site.
• Key Findings:
  • The Great Bath: A massive rectangular ritual bathing pool made of watertight bricks (using bitumen).
  • The Great Granary: The largest building discovered at Mohenjo-Daro.
  • Multi-pillared assembly hall.
  • A piece of woven cotton (proving weaving was practiced).
  • The famous bronze statue of a nude Dancing Girl.
  • The steatite (soapstone) bust of a bearded priest-king, draped in a shawl with trefoil patterns.
  • The Pashupati Seal, depicting a proto-Shiva figure.

Lothal (Gujarat, India)

• Location: Located on the coastal flats of the Gulf of Khambhat on the Bhogava river. It served as a major port city facing the Arabian Sea.
• Key Findings:
  • An artificial brick Dockyard, the earliest known in the world, connected to the river to handle maritime trade.
  • Extensive bead-making factory (suggesting it was an industrial town).
  • Fire altars, indicating the practice of sacrifices.
  • A unique "Double Burial" (a male and female buried together).
  • Earliest evidence of rice cultivation (rice husk found).

Kalibangan (Rajasthan, India)

• Location: Situated on the banks of the now-dry Ghaggar (Sarasvati) river in Hanumangarh district. "Kalibangan" means black bangles.
• Key Findings:
  • Evidence of an early ploughed field (the earliest in the world) with parallel furrow marks, indicating mixed cropping.
  • Seven rectangular fire altars, suggesting communal fire rituals.
  • Unlike other cities, the houses here were largely made of mud-bricks, whereas baked bricks were used primarily for drains and wells.
  • Cylindrical seal found, similar to Mesopotamian seals.

Dholavira (Gujarat, India)

• Location: Located in the Rann of Kutch (Khadir Beyt island).
• Key Findings:
  • Unique town planning: The city was exclusively divided into three parts (Citadel, Middle Town, Lower Town).
  • Massive stone architecture (not just bricks).
  • Highly advanced and elaborate water harvesting and management system featuring a large stadium-like reservoir and dams.
  • A massive "Signboard" containing 10 large Harappan script symbols.

4. Harappan Art and Architecture and the Script

Harappan art reflects a pragmatic and utilitarian approach over monumental display.

• Seals: The most remarkable artistic creations are the steatite (soapstone) seals, mostly square or rectangular. They feature magnificent animal figures (unicorn, bull, rhino) and a short inscription. They were likely used for commercial purposes (as stamps).
• Terracotta: Elaborate baked clay figures of mother goddesses, toy carts, and animals (bulls, monkeys, dogs). They represent the popular art of the common people.
• Sculptures: While rare, the bronze "Dancing Girl" (made using the lost-wax casting technique / Cire Perdue) and the stone bust of the bearded priest-king demonstrate high artistic skill.
• The Harappan Script: The script is purely indigenous and pictographic (using pictures to represent words/sounds). It has yet to be deciphered. It was generally written from right to left (if single line), or right to left on the first line and left to right on the second (Boustrophedon style).

5. Decline of the Harappan Culture

The mature Harappan phase began to decline around 1900 BCE, eventually fading away. The decline was gradual, leading to a largely rural "Late Harappan" phase. There is no single universally accepted reason for the decline; it was likely a combination of ecological and human factors.

Major Theories of Decline:

• Aryan Invasion (Mortimer Wheeler): Proposed that invading Aryans destroyed the IVC. Evidence cited includes unburied skeletons found in the streets of Mohenjo-Daro and mention of Indra as "Purandara" (destroyer of forts) in the Rig Veda. This theory is largely discarded today due to a lack of archaeological proof of massive conflict.
• Ecological Imbalance and Climate Change: Gradual desiccation of the environment due to over-exploitation of resources (deforestation for brick-baking), leading to weakened monsoons and reduced agricultural output.
• Tectonic Activity and Floods (Robert Raikes): Frequent, devastating floods in the Indus river caused by tectonic uplifts, which could have submerged entire cities (like Mohenjo-Daro, which shows multiple layers of rebuilding after floods).
• Drying up of Rivers (D.P. Agrawal): The tectonic shifts caused the mighty Sarasvati-Ghaggar-Hakra river system to dry up, leaving major urban centers like Kalibangan stranded without water.

The most accepted view today is that of environmental and climatic changes—a shift in monsoon patterns leading to a prolonged drought, combined with the drying up of the Sarasvati, forcing the population to migrate eastward towards the Ganga-Yamuna plains, leading to the de-urbanization of the civilization.
