The beginning of Indian Civilization

Overview & Fundamental Concept

Pointwise AISSEE Class 9 Social Science guide for The Beginning of Indian Civilization: Harappan Civilization (Topic 15). Explains grid town planning, Great Bath, Lothal dockyard, Dholavira water engineering, seals, trade, and decline theories with solved models and 10 drills.

• The Indus Valley / Harappan Civilization: The earliest urban civilization in South Asia, thriving during the Bronze Age between ~2600 BCE and 1900 BCE.
• Archaeological Discovery Benchmarks:
  • Harappa: Discovered in 1921 by Rai Bahadur Dayaram Sahni on the banks of the Ravi River (Punjab, Pakistan). Because Harappa was the first site excavated, the entire civilization is officially named the Harappan Civilization.
  • Mohenjo-daro ('Mound of the Dead'): Discovered in 1922 by Rakhaldas (R.D.) Banerjee on the banks of the Indus River (Sindh, Pakistan).
  • Director-General of Archaeological Survey of India (ASI) Sir John Marshall formally announced the discovery of this ancient civilization to the world in 1924.
• Sophisticated Town Planning (Grid System):
  • Two-Part Town Division: Cities were typically divided into two distinct sections:
    1. The Citadel / Acropolis (Western Part): Smaller in area but built on a high raised platform of mud bricks. Housed monumental public buildings, grain storehouses, and ceremonial structures. Fortified by protective walls.
    2. The Lower Town (Eastern Part): Much larger in area, situated lower down; consisted of residential brick houses for the common citizenry.
  • The Grid Pattern: Broad streets ran straight from north to south and east to west, intersecting each other at precise right angles ($90^circ$), dividing the city into neat rectangular blocks.
  • Standardized Baked Bricks: Houses were constructed using oven-baked terracotta bricks of standardized proportions (ratio 1:2:4 in thickness, width, and length) laid in an interlocking bonding pattern, giving walls incredible structural longevity.
• The World's First Covered Drainage System:
  • Every house had its own paved bathroom and wastewater drain connected to covered street drains.
  • Drains were laid out in straight lines along streets with gentle gradients to prevent water stagnation.
  • Street drains were covered with stone slabs or baked bricks.
  • Provided with inspection holes (manholes) at regular intervals for sanitation maintenance — an urban sanitation level unmatched in the ancient world until Roman times!

• 1. Mohenjo-daro (Sindh, Pakistan):
  • The Great Bath: A rectangular brick tank measuring roughly 12m × 7m and 2.4m deep. Lined with finely fitted baked bricks, plastered with mortar, and sealed water-tight with a layer of natural tar / bitumen. Flight of steps on north and south led into the pool; surrounded by dressing rooms. Fed by an adjacent well. Believed to be used for ceremonial religious bathing.
  • The Great Granary: Massive air-ventilated storehouse for grain reserves.
  • Bronze Dancing Girl: World-famous lost-wax bronze casting depicting a graceful young girl with bangles on her left arm.
  • Steatite Bearded Priest: Statue showing an elite figure wearing an embroidered shawl.
• 2. Harappa (Punjab, Pakistan):
  • Series of 12 granaries arranged in two rows of six; working platforms with circular brick floors for threshing grain; workmen's quarters.
• 3. Lothal (Gujarat, India):
  • Located along the Bhogava River (a tributary of the Sabarmati), near the Gulf of Khambhat.
  • Ancient Tidal Dockyard: Massive rectangular basin of burnt bricks where ocean-going ships arrived via tidal channels from the Arabian Sea, making it a bustling international maritime trading port connected to Mesopotamia.
  • Bead-making factory and fire altars.
• 4. Kalibangan ('Black Bangles' • Rajasthan, India):
  • Situated on the banks of the dried-up Ghaggar River.
  • Archaeological evidence of the earliest ploughed agricultural field on Earth, showing intersecting furrow lines.
  • Presence of ritual brick fire altars used for sacrificial offerings.
• 5. Dholavira (Rann of Kutch, Gujarat, India):
  • Located on Khadir Bet in the Great Rann of Kutch.
  • Unique 3-Part Division: Unlike other Harappan cities divided into two parts, Dholavira was divided into three distinct fortified parts: Citadel, Middle Town, and Lower Town, each enclosed by massive stone walls.
  • Master Water Engineering: Gigantic rock-cut and masonry water reservoirs to collect stormwater.
  • The Signboard: Ten large white crystalline Harappan pictographic letters inlaid into a wooden signboard.
• 6. Other Notable Sites:
  • Chanhudaro (Sindh): Exclusive industrial manufacturing center for beads, shell cutting, and metallic seals (no citadel!).
  • Banawali (Haryana): Terracotta toy plough discovered.
  • Rakhigarhi (Haryana): Largest Harappan site on Indian territory.

• Agriculture & Diet: Cultivated wheat, barley, pulses, peas, sesame, mustard, and rice (rice husks found at Lothal and Rangpur). They were the first people in the world to cultivate cotton (Greeks called cotton Sindon, derived from Sindh).
• Trade & Standardization:
  • Active overland and maritime trade with Mesopotamia (Sumer). Mesopotamian inscriptions refer to the Indus region as 'Meluha'.
  • Standardized Weights & Measures: Cubical weights made of chert stone following a binary system in lower denominations (1, 2, 4, 8, 16, 32... up to 160) and decimal system in higher denominations.
• Harappan Script: Pictographic script with symbols depicting birds, fish, and human forms. Written right-to-left (boustrophedon style). It remains undeciphered to this day.
• Theories for the Decline of Harappan Civilization (~1900 BCE):
  • Around 1900 BCE, cities began deteriorating; streets were uncleaned, garbage accumulated, and population migrated eastwards toward the Gangetic plains.
  • Prominent Causes:
    1. Ecological climate change and drying up of the sacred Saraswati River (Ghaggar-Hakra).
    2. Catastrophic recurring floods on the Indus River.
    3. Deforestation caused by continuous burning of wood to bake millions of bricks.
    4. Overgrazing destroying natural grass cover and triggering desertification.
