Indus Valley Civilization for UPSC CSE Prelims

 

1. Introduction

The Indus Valley Civilization (IVC), also known as the Harappan Civilization, was one of the world’s earliest urban civilizations, flourishing in the northwestern part of the Indian subcontinent. It is a Bronze Age civilization known for its advanced urban planning, trade, and cultural achievements.

2. Time Period

• Mature Phase: ~2600 BCE to 1900 BCE
• Broad Timeline: Early Harappan (3300–2600 BCE), Mature Harappan (2600–1900 BCE), Late Harappan (~1900–1300 BCE)

3. Geographical Extent

• Spread across modern-day India, Pakistan, and parts of Afghanistan.
• Covered regions along the Indus River and Ghaggar-Hakra River systems.
• Major areas: Punjab, Sindh, Gujarat, Rajasthan, Haryana, and western Uttar Pradesh.
• Approximate area: ~1.5 million sq. km, making it the largest ancient civilization.

4. Major Sites and Their Features

• Harappa (Punjab, Pakistan):
  • Granaries, citadel, and advanced drainage system.
  • Evidence of craft specialization (beads, pottery).
• Mohenjo-Daro (Sindh, Pakistan):
  • Great Bath (public bathing structure, possibly ritualistic).
  • Advanced urban planning with grid-pattern streets.
  • Evidence of a large granary and drainage systems.
• Dholavira (Gujarat, India):
  • Unique water conservation system with reservoirs.
  • Large signboard with Indus script.
  • Sophisticated town planning with three divisions (citadel, middle town, lower town).
• Lothal (Gujarat, India):
  • World’s earliest known dockyard, indicating maritime trade.
  • Bead-making workshops and warehouse.
• Kalibangan (Rajasthan, India):
  • Evidence of plowed fields (early agriculture).
  • Fire altars, suggesting ritual practices.
• Rakhigarhi (Haryana, India):
  • One of the largest IVC sites.
  • Evidence of planned streets and drainage systems.
• Banawali (Haryana, India):
  • Well-planned city with radial streets.
  • Barley cultivation evidence.
• Surkotada (Gujarat, India):
  • Evidence of horse bones (controversial).
  • Citadel with fortifications.

5. Key Features of IVC

• Urban Planning:
  • Grid-pattern layout with streets at right angles.
  • Advanced drainage systems with covered drains.
  • Standardized burnt bricks (ratio 4:2:1) for construction.
  • Cities divided into citadel (elevated, fortified area) and lower town.
• Economy:
  • Agrarian-based with cultivation of wheat, barley, cotton, and pulses.
  • Domestication of animals (cattle, buffalo, goats).
  • Extensive trade with Mesopotamia, Persia, and Central Asia (evidenced by seals and artifacts).
  • Use of standardized weights and measures.
• Technology and Crafts:
  • Bronze and copper tools; bead-making (carnelian, agate).
  • Pottery with red and black designs (Black-on-Red Ware).
  • Cotton textile production (world’s earliest known).
• Script and Language:
  • Indus script: Pictographic, found on seals, pottery, and tablets.
  • Undeciphered; written right to left (possibly).
• Religion:
  • No temples found; possible worship of mother goddess, proto-Shiva (Pashupati seal), and nature deities.
  • Fire altars at Kalibangan and Lothal suggest rituals.
• Social Structure:
  • Likely egalitarian; no evidence of palaces or extreme social hierarchy.
  • Craft specialization indicates division of labor.

6. Decline of IVC (~1900 BCE)

• Theories of Decline:
  • Environmental Changes: Drying of Ghaggar-Hakra River (Saraswati), climate change, and floods.
  • Aryan Invasion Theory: Largely discredited; no strong evidence.
  • Economic Decline: Disruption of trade networks with Mesopotamia.
  • Ecological Degradation: Deforestation, soil exhaustion, and overgrazing.
• Late Harappan Phase: Gradual shift to smaller settlements; some cultural continuity in Gujarat and Haryana.

7. Significance

• One of the four great ancient civilizations (alongside Mesopotamia, Egypt, and China).
• Advanced urban planning and sanitation unmatched for its time.
• Contributed to later Indian culture (e.g., agriculture, crafts, trade practices).

8. Key Points for UPSC CSE Prelims

• Chronology: Early (3300–2600 BCE), Mature (2600–1900 BCE), Late (~1900–1300 BCE).
• Major Sites:
  • India: Dholavira, Lothal, Kalibangan, Rakhigarhi, Banawali.
  • Pakistan: Harappa, Mohenjo-Daro.
• Unique Features:
  • Great Bath (Mohenjo-Daro), dockyard (Lothal), water reservoirs (Dholavira).
  • Standardized bricks, weights, and measures.
  • Undeciphered Indus script.
• Economy: Agriculture (wheat, barley, cotton), trade with Mesopotamia.
• Decline: Likely due to environmental factors; Aryan invasion theory discredited.
• Map-Based Questions: Be prepared to locate sites (e.g., Dholavira in Gujarat, Harappa in Punjab).
• Cultural Aspects: Mother goddess, Pashupati seal, fire altars.

9. Exam Tips

• Focus Areas: Memorize major sites, their locations, and unique features (e.g., Great Bath, dockyard).
• Map Questions: Practice identifying IVC sites on a map of India and Pakistan.
• Chronology: Understand the timeline and phases (Early, Mature, Late Harappan).
• Decline Theories: Know the environmental and economic factors; avoid outdated invasion theories.
• Artifacts: Familiarize with seals, pottery, and standardized weights for MCQs.
