V. Answer Briefly (2-mark questions)

Q1. What is the significance of the Great Bath at Mohenjo-daro?

AnswerThe Great Bath is a large rectangular tank (approximately 12 m x 7 m, 2.4 m deep) built of baked bricks, located in the citadel area of Mohenjo-daro. It had steps leading down on two sides and was surrounded by rooms, possibly used by priests. Its significance lies in:
  • It indicates the importance of ritual bathing and cleanliness in Harappan culture.
  • It reflects advanced hydraulic engineering — the tank was made water-tight using a layer of natural tar.
  • It suggests a well-organised authority capable of building and maintaining large public works.

Q2. What do the seals tell us about the Harappan civilisation?

AnswerHarappan seals — over 2,000 have been found — are small, rectangular or square steatite objects with pictographic script and animal motifs. They tell us that:
  • The Harappans engaged in long-distance trade; seals have been found in Mesopotamia.
  • There was an administrative authority that standardised weights, measures, and seal iconography.
  • The unicorn was the most common animal depicted, possibly a political or cultural symbol.
  • The presence of script alongside animals suggests a system of ownership, branding, or record-keeping.

Q3. Name four major Indus Valley sites and mention what each is known for.

Answer1. Harappa — Discovered in 1921 by Daya Ram Sahni; known for Cemetery R-37 and granaries. 2. Mohenjo-daro — Discovered in 1922 by R. D. Banerjee; known for the Great Bath, the Great Granary, and the Bronze Dancing Girl. 3. Lothal — Known for its dockyard (the earliest known), bead-making factory, and evidence of rice. 4. Dholavira — Known for its unique three-part town layout, large signboard with Indus script, and advanced water conservation system with reservoirs.

Q4. What evidence shows the Indus people traded with Mesopotamia?

Answer
  • Harappan seals, pottery, and beads have been found at Mesopotamian sites like Ur, Kish, and Tell Asmar.
  • Mesopotamian texts refer to trade with a land called Meluhha, which most scholars identify as the Indus region.
  • Items such as carnelian beads, ivory combs, and wooden objects of Indus origin were found in Mesopotamia.
  • Lothal's dockyard and coastal sites suggest the Harappans had maritime trade routes.

Q5. What is the difference between the citadel and the lower town in Harappan cities?

Answer
  • The citadel is the raised, western part of the city, built on a mud-brick platform. It housed important public buildings like the Great Bath, granaries, and assembly halls. It suggests the ruling or priestly class lived or operated here.
  • The lower town is the larger, eastern part where the common people lived. It had residential houses, workshops, and markets. Despite being for commoners, it also had well-planned streets and drainage.

VI. Answer in Detail (5-mark questions)

Q1. Describe the town planning and drainage system of the Indus Valley Civilisation.

Answer

The Indus Valley Civilisation is renowned for its remarkable urban planning, far ahead of its time:

Town Planning:

  • Grid Pattern: Streets ran north-south and east-west, cutting at right angles. This grid pattern is visible at all major sites — Harappa, Mohenjo-daro, and Kalibangan.
  • Division into Citadel and Lower Town: Each major city was divided into a raised western citadel and a larger lower town to the east, built on a mud-brick platform for flood protection.
  • Standardised Brick Size: Harappan bricks followed a standard ratio of 4:2:1 (length:width:height), indicating centralised control over construction.
  • Well-Planned Houses: Houses were built around courtyards, with rooms opening into the courtyard. Many had private wells and bathrooms. Houses did not open directly onto main streets but onto side lanes.
  • Public Buildings: Granaries, the Great Bath, and large halls suggest organised communal activity and governance.

Drainage System:

  • House Drains: Every house had a bathroom and a drain carrying wastewater to the street drain.
  • Street Drains: Covered drains ran along the streets, made of burnt bricks. They had inspection holes at intervals so they could be cleaned.
  • Soak Pits: Some drains emptied into soak pits or cesspits, an early form of sewage treatment.
  • Sloped Floors: Bathroom floors were sloped so water would flow towards the drain.
  • Municipal Supervision: The uniformity and scale of the drainage network suggest a central municipal authority maintained public hygiene.

This level of urban planning was unmatched in the contemporary world and was not seen again in the Indian subcontinent until the modern era.


Q2. Discuss the socio-economic life of the Harappan people.

Answer

Social Life:

  • Social Stratification: The citadel-lower town division suggests social hierarchy. The ruling or priestly class may have lived in the citadel while commoners occupied the lower town.
  • Dress and Ornaments: People wore cotton and woollen garments. Both men and women wore ornaments — necklaces, bangles, earrings, and anklets made of gold, silver, copper, and semi-precious stones.
  • Recreation: Dice, gaming boards, and toys (whistles, carts, animals) have been found, showing leisure activities. The Great Bath suggests ritual swimming or communal bathing.
  • Religion: No large temples have been found, but seals depicting a horned figure (Pashupati Seal), mother goddess figurines, and the pipal tree indicate nature worship and possibly a mother goddess cult. Fire altars have been found at Kalibangan and Lothal.
  • Burial Practices: The dead were buried in graves, sometimes with pottery and ornaments. Cemetery R-37 at Harappa shows careful burial practices.

Economic Life:

  • Agriculture: The main crops were wheat, barley, sesame, and dates. Rice evidence appears at Lothal and Rangpur. The Harappans used irrigation and ploughed fields (evidence at Kalibangan).
  • Animal Husbandry: Cattle, buffalo, sheep, goats, and pigs were domesticated. The horse is debated — few remains have been found.
  • Crafts and Industries: Bead-making (Lothal), pottery (on the wheel), metallurgy (lost-wax casting for the Bronze Dancing Girl), weaving, and shell-working were major crafts.
  • Trade: Both internal and external trade were important. The Harappans traded with Mesopotamia (called Meluhha), Persia, and Afghanistan. Lothal served as a port town. Standardised weights and measures facilitated trade.

The Harappan economy was a mixed one — agricultural surplus supported craft production and long-distance trade.


Q3. Explain the various theories about the decline of the Indus Valley Civilisation.

Answer

The decline of the Indus Valley Civilisation around 1900 BCE remains one of archaeology's greatest unsolved puzzles. No single theory is fully accepted. The major explanations are:

1. Environmental Changes and Natural Disasters:
Answer
  • Shifts in river courses — the Saraswati/Ghaggar-Hakra river dried up, affecting settlements along its banks.
  • Decreased monsoon rainfall leading to drought and agricultural failure.
  • Tectonic activity may have altered river paths or caused flooding. The Indus river shifted away from Mohenjo-daro, depriving it of water.
  • Evidence of flooding at Mohenjo-daro (silt deposits) suggests repeated inundations.
2. Decline of Trade with Mesopotamia:
Answer
  • Around 2000 BCE, the Mesopotamian trade network weakened as the Akkadian and later the Babylonian empires faced instability.
  • Reduced demand for Harappan goods (carnelian beads, ivory) would have impacted the economy severely, especially for port cities like Lothal.
3. Aryan Migration/Invasion Theory:
Answer
  • Early scholars like Mortimer Wheeler proposed that Indo-Aryan invaders destroyed Harappan cities, citing Rig Vedic references to conflicts.
  • However, no archaeological evidence of large-scale warfare or destruction has been found at most Harappan sites. This theory is now largely rejected or significantly modified.
4. Internal Decline and Socio-Economic Factors:
Answer
  • Overuse of resources and deforestation may have degraded the environment over centuries.
  • Breakdown of central authority could have led to the abandonment of urban features (drainage maintenance, standardised brick sizes).
  • The transition from the mature urban phase to the late Harappan phase was likely gradual, not sudden.

Modern View: Most scholars now favour a combination of environmental stress (climate change, river shifts) compounded by declining trade and internal socio-economic fragmentation. The civilisation did not collapse overnight — it gradually de-urbanised, with people migrating eastward and southward, giving rise to late Harappan and post-urban cultures.


Common Mistakes to Avoid

  • Calling the Indus Civilisation rural: It was one of the world's earliest urban civilisations with planned cities, advanced drainage, and public buildings. Never call it a village or rural culture.
  • Claiming the Indus script is deciphered: The script remains undeciphered. Do not state any "translation" as fact. Avoid attributing a specific language (Sanskrit or Dravidian) as confirmed.
  • Saying iron was used by the Harappans: Iron was not known to the Indus people. Bronze (copper + tin) was the primary metal. Iron came to India during the later Vedic period.
  • Confusing discovery dates: Harappa was discovered in 1921 by Daya Ram Sahni, and Mohenjo-daro in 1922 by R. D. Banerjee. Do not swap the sites or dates.
  • Attributing the decline solely to Aryan invasion: The invasion theory is outdated. The decline was likely multi-causal — environmental change, trade decline, and internal factors — not just invasion.
  • Confusing the mature phase dates with the overall civilisation timeline: The mature urban phase is 2600-1900 BCE. The Early Harappan phase goes back to c. 3300 BCE. Do not write the civilisation span as only 2600-1900 BCE unless the question specifically asks about the urban phase.
  • Saying the Great Bath was at Harappa: It was at Mohenjo-daro. Harappa had granaries and Cemetery R-37.
  • Confusing Neolithic with Paleolithic features: Neolithic = agriculture, settled life, pottery. Paleolithic = hunting, gathering, nomadic. Do not mix them up.
