Indus Valley Civilization — Key Facts for BPSC

The Indus Valley Civilization (IVC), also called the Harappan Civilization, flourished c. 3300–1300 BCE across a vast area of the Indian subcontinent. It was one of the world’s earliest urban civilizations alongside Mesopotamia and Egypt.

Core Facts:

• Three major cities: Harappa, Mohenjo-daro, and Dholavira (Gujarat — recently added to UNESCO World Heritage)
• Town planning: grid pattern, standardized brick sizes, advanced drainage system
• Script: undeciphered Harappan script (over 400 signs identified)
• Seals: square/rectangular steatite seals with animal motifs (most famous: Pashupati Seal)
• Trade: active trade with Mesopotamia, Mesopotamia mentions “Meluhha” (likely IVC)
• Major crops: wheat, barley; domesticated elephants and camels
• Script runs right to left in some cases; uniclassified

Vedic Period — Key Facts:

• Rigveda (c. 1500–1000 BCE) is the oldest text; contains 10 mandalas, 1028 hymns
• Purusha Sukta (Rigveda 10.90) describes the four varnas
• Two major epics associated: Ramayana and Mahabharata
• Later Vedic period saw the rise of 16 Mahajanapadas

⚡ Exam tip: BPSC consistently asks questions on IVC sites, seals, town planning, and Vedic literature. The Pashupati Seal is a frequent favourite.

Indus Valley Civilization (c. 3300–1300 BCE)

Discovery & Extent

Sir Alexander Cunningham identified Harappa in 1875. The civilization extended across Pakistan, northwest India (Gujarat, Haryana, Punjab, Rajasthan) — over 1,000 sites identified. Major centres: Harappa (Punjab), Mohenjo-daro (Sindh), Dholavira (Gujarat), Rakhigarhi (Haryana — now in UNESCO tentative list), Lothal (Gujarat — known for world’s earliest dockyard).

Urban Planning

The hallmark of IVC cities was their grid-pattern layout:

• Streets cutting at right angles
• Uniform brick sizes (ratio 1:2:4 — no variation across the civilization)
• Great Bath at Mohenjo-daro — possibly the world’s earliest public water tank (used for ritual bathing?)
• Advanced drainage and sewage systems with covered brick-lined channels
• Granaries at Harappa and Mohenjo-daro for grain storage

This uniformity suggests centralized planning or a governing authority, though no palaces or temples have been conclusively identified.

Economy & Trade

• Agriculture: wheat, barley, cotton, dates, sesame
• Domesticated animals: bull, buffalo, goat, sheep, elephant, camel (single-humped)
• Maritime trade with Mesopotamia (Mesopotamian texts mention Meluhha)
• Export items: carnelian beads, cotton textiles, timber, ivory
• Lothal had a dockyard — evidence of maritime trade
• Weights and measures were standardized (binary and decimal systems)

Religious & Cultural Life

• Pashupati Seal shows a seated figure (possibly Shiva/Proto-Shiva) in a yogic posture surrounded by animals
• Worship of Mother Goddess (terracotta figurines)
• Fire altars found — possible evidence of ritual practices resembling later Vedic yajnas
• No clear evidence of temple structures; burial practices included complete burial (supine position), sometimes with funerary goods
• The unicursal swastika appears frequently on seals

Script

The Harappan script has over 400 signs and remains undeciphered. It is the oldest script of the Indian subcontinent, pre-dating Brahmi by several centuries.

Decline — Theories

1. Aryan Invasion Theory (outdated): Maxwell Master’s migration theory suggested Indo-Aryan migration caused decline
2. Climate Change: Evidence of monsoon failure around 2000 BCE
3. River shift: Saraswati drying up (supported by archaeological and literary evidence)
4. Floods: Geomorphological evidence of flood events at Dholavira and Mohenjo-daro

Vedic Period (c. 1500–500 BCE)

Early Vedic Period (c. 1500–1000 BCE)

• Rigveda — oldest Veda, composed in Sapta Sindhu region (Punjab, Afghanistan)
• Ten mandalas — Mandala 2 (Vashistha), 3 (Vishwamitra), 6–7 (family books)
• Society was pastoral and tribal; no caste system in early Vedic times
• Gods: Indra (warrior god, slayer of Vritra — the drought demon), Agni (fire), Soma (ritual drink), Varuna (cosmic order), Mitra, Usha (dawn)
• Gavam ayana (cow raids) were common — cattle was the main form of wealth (“gavishti”)
• Sabha and Samiti — early democratic institutions
• Rituals: Soma sacrifice, Ashvamedha (horse sacrifice), Rajasooya

Later Vedic Period (c. 1000–500 BCE)

• Expansion eastward into the Gangetic Plain — major shift from pastoral to agrarian economy
• Krishna Yajurveda and Shukla Yajurveda emerged
• Rise of 16 Mahajanapadas (major kingdoms):
  • Magadha (Bihar) — would later dominate Indian politics
  • Kosala, Kashi, Vajji (Bihar — first republic/sangha), Malla
• Society became more stratified:
  • Varnashrama system crystallized (Brahmin, Kshatriya, Vaishya, Shudra)
  • Ashrama system: Brahmacharya, Grihastha, Vanaprastha, Sannyasa
  • Purusha Sukta (Rigveda 10.90) codifies varna ideology
• Upanishads composed during this period — philosophical texts on Brahman-Atman
• Iron usage increased (Painted Grey Ware culture in Ganga valley)
• Cities grew; Rajagriha (Rajgir) and Vaishali emerged as major centres
• Rise of Shramana movement (Jainism, Buddhism) and Ajivika philosophy

Key Upanishads & Texts

• Brihadaranyaka and Chandogya Upanishads — major philosophical works
• Brahmana texts: Satapatha Brahmana (Shukla Yajurveda)
• Early Dharmasutras codifying social norms
• Valmiki Ramayana and growing Mahabharata traditions

Important Concepts for BPSC

• Varna system vs caste — understand the distinction
• Sabha and Samiti — early democratic institutions (relevant for BPSC questions on ancient governance)
• Magadha’s rise as the dominant power — geography + iron + strong monarchy
• Ajanta-Vaijayanti mentions of the 16 Mahajanapadas

⚡ Study strategy: Focus on sites, seals, Vedic literature names, and the distinction between early and later Vedic society.

Detailed Chronology & Key Events

Harappan Chronology

Phase	Period	Characteristics
Early Harappan	3300–2600 BCE	Pre-urban, rural settlements
Mature Harappan	2600–1900 BCE	Full urbanization, grid planning
Late Harappan	1900–1300 BCE	Decline, migration, peripheral sites

Major IVC Sites (Important for BPSC)

• Harappa (Pakistan): Named the civilization; “R1” cemetery, granaries
• Mohenjo-daro (Pakistan): Great Bath, Great Hall, Pashupati Seal
• Lothal (Gujarat, India): World’s earliest dockyard, biconical beads, rice husk
• Dholavira (Gujarat, India): UNESCO World Heritage (2021), star-shaped reservoir, unique water management
• Rakhigarhi (Haryana, India): Pre-Indus Valley occupations, necropolis
• Kalibangan (Rajasthan, India): Fire altars, furrowed fields, part of Ghaggar-Hakra civilization
• Chanhudaro (Pakistan): Only city without a citadel; inkpot and school

Vedic Literature Hierarchy

1. Shruti (heard): Vedas → Samhitas → Brahmanas → Aranyakas → Upanishads
2. Smriti (remembered): Dharmashastras, Puranas, Itihasas (Ramayana, Mahabharata)
3. Vedangas (limbs of Vedas): Shiksha, Vyakarana, Nirukta, Chhanda, Jyotisha, Kalpa

Indus Script — Current Understanding

• Over 4,000 inscriptions found
• Average length: 5 signs
• Most seals have clockwise swastika and animal motifs
• Not Proto-Dravidian, Proto-Brahmi, or Proto-Elamite conclusively

Archaeological Cultures Linked to Vedic Period

• Painted Grey Ware (PGW): Associated with later Vedic / early Buddhist period in Ganga valley; iron used
• Black-Figure Red Ware: Eastern India, post-Vedic
• Malwa Culture: Central India, continuous tradition

BPSC-Specific Focus Areas

• Bihar’s place in the Vedic world: Vajji (first republic in history, in Bihar), Magadha (dominant Mahajanapada)
• Vaishali — capital of Vajji, mentioned in both Buddhist and Jain texts; site of the Second Buddhist Council
• The Sakya clan (Buddha’s clan) from the region

Previous Year BPSC Questions (Pattern)

• IVC site locations, urban planning features, seals, script
• Vedic gods and their functions
• Difference between early and later Vedic society
• Mahajanapadas and the shift to monarchical states
• Buddhism and Jainism — causes, spread, key differences

Common Mistakes to Avoid

• Don’t confuse Indus script with Brahmi (Brahmi is the ancestor of all Indian scripts)
• Don’t assume caste was rigid in early Vedic period — it evolved
• Don’t confuse IVC decline with Aryan invasion — the migration theory is largely abandoned
• Remember that Buddha’s lifetime (c. 563–483 BCE) falls in the 6th century BCE — this is the “Second Urbanization” period
