Ancient History
Indus Valley Civilisation (c. 2600–1900 BCE)
Also known as Harappan Civilization, it was one of the world’s earliest urban civilizations, located primarily in present-day Pakistan and northwest India.
1. Urban Planning
The IVC cities were known for highly advanced urban planning, indicating a strong central authority and civic organization.
Key Features:
- Grid Pattern: Cities like Mohenjo-Daro and Harappa were laid out in a grid system – streets ran north-south and east-west, intersecting at right angles.
- Division into Citadel and Lower Town:
- Citadel (Western part): Raised and fortified; housed granaries, administrative buildings, religious structures.
- Lower Town (Eastern part): Residential area where common people lived.
- Standardized Bricks: Burnt bricks of uniform size (ratio 1:2:4) used for construction.
Significance: Suggests planning was done before construction and indicates advanced knowledge of geometry and measurement.
2. Drainage System
Perhaps the most remarkable feature of the IVC.
Key Features:
- Covered Drainage: Every house was connected to a central drainage line running along the street.
- Inspection Chambers: Provided at intervals for cleaning and maintenance.
- Water Management: Separate drains for rainwater and wastewater; public wells were common.
- Soak Pits and Cesspools: Used to trap solid waste before liquid flowed into the drains.
Significance: Shows concern for hygiene, public health, and technical skill in water engineering.
3. Harappa
- Location: Present-day Punjab, Pakistan; discovered in 1921 by Daya Ram Sahni.
- City Structure:
- Two distinct parts: Citadel and Lower Town.
- Granary with ventilation; possibly a trade or storage hub.
- Artifacts: Terra-cotta figurines, seals, weights, and tools.
Significance – Harappan seals, made of steatite, often depicted animals and script, indicating literacy and trade links.

4. Mohenjo-Daro
- Location: Sindh, Pakistan; discovered in 1922 by R.D. Banerjee.
- City Features:
- Great Bath: Large tank-like structure, possibly used for ritual bathing.
- Granary: Near citadel, had air ducts for preservation.
- Assembly Hall: Large pillared hall possibly for gatherings.
- Residential Houses: Well-planned with courtyards, bathrooms, private wells.
Significance – Mohenjo-Daro is often termed the “City of Wells”, with more than 700 wells unearthed so far.
