Pre-Historic India

Stone Age

  • Palaeolithic (Old Stone Age, 5 lakh–10,000 BCE): Stone tools (choppers, flakes); hunter-gatherers; cave paintings (Bhimbetka, Madhya Pradesh — UNESCO World Heritage Site)
  • Mesolithic (Middle Stone Age, 10,000–6000 BCE): Microlithic tools; nomadic lifestyle
  • Neolithic (New Stone Age, 6000–1000 BCE): Agriculture begins; pottery; domestication of animals; Mehrgarh (Balochistan) — earliest agricultural settlement in South Asia (7000 BCE)
  • Chalcolithic (Copper-Stone Age, 1500–1000 BCE): Copper + stone tools; Jorwe, Malwa, Kayatha cultures in Deccan

Indus Valley Civilisation (2500–1750 BCE)

Overview

Also called Harappan Civilisation (after the first discovered site, Harappa in Punjab, Pakistan).

Discovery: Harappa excavated by Daya Ram Sahni (1921); Mohenjo-daro by R.D. Banerji (1922) under John Marshall, Director-General of ASI.

Extent: Covered 1.3 million sq km — largest of the three ancient civilisations (larger than Egypt and Mesopotamia combined). From Balochistan in the west to Meerut in the east; from Kashmir in the north to Gujarat in the south.

Timeline:

  • Early phase: 3200–2600 BCE
  • Mature phase (peak): 2600–1900 BCE
  • Late/Decline phase: 1900–1300 BCE

Key Features

  • Urban planning: Grid streets, standardised burnt bricks (4:2:1 ratio), multi-storeyed houses
  • Great Bath (Mohenjo-daro): Large water tank — possibly for ritual purification; bitumen waterproofing
  • Drainage system: Covered drains — world's first civic sanitation
  • Granaries: Stored grain — indicate surplus production and administration
  • Weights and measures: Standardised across the civilisation — suggest central authority
  • Script: Pictographic, undeciphered — about 400 signs. Written right to left (boustrophedon in some examples)
  • Trade: Internal trade in copper, tin, lapis lazuli; external trade with Mesopotamia (called Meluhha in Sumerian texts)
  • No temples or palaces identified — suggests different governance from Mesopotamia/Egypt
  • Animals: Unicorn (most depicted on seals), elephant, rhinoceros, tiger, bull

Vedic Age (1500–600 BCE)

Early Vedic Period (1500–1000 BCE)

Rigveda: Oldest of four Vedas; 1,028 hymns; composed by Aryans.

  • Major gods: Indra (thunder, war — most hymns), Agni (fire), Varuna (water/cosmic order), Soma (ritual drink)
  • Society: Tribal; Jana (tribe), Kula (family), Vis (clan)
  • Women could compose hymns (Gargi, Lopamudra); widow remarriage allowed
  • Cattle = primary wealth; no iron; horses used for chariot warfare

Later Vedic Period (1000–600 BCE)

Other three Vedas: Samaveda (music/melodies), Yajurveda (sacrifice rituals), Atharvaveda (spells/charms)

Upanishads: Philosophical texts exploring nature of Brahman (ultimate reality) and Atman (individual soul). Basis of Vedanta philosophy.

Rigidity increases:

  • Varna system crystallised: Brahmin (priests) > Kshatriya (warriors) > Vaishya (merchants) > Shudra (servants)
  • Iron Age: Iron ('Krishna Ayas') enabled forest clearing and agriculture in Gangetic plains
  • Capital cities emerge: Hastinapur, Indraprastha (Mahabharata era)
  • Women's status declined

Epic Period:

  • Ramayana: Attributed to Valmiki — Rama's story; historical core: ~500 BCE
  • Mahabharata: Attributed to Vyasa — Pandavas vs Kauravas; Bhagavad Gita within it; core: ~400 BCE

Mahajanapadas and Rise of New Religions (600–321 BCE)

16 Mahajanapadas: Large kingdoms in 6th century BCE: Magadha, Kosala, Kashi, Vajji (Vaishali — republican), Chedi, Vatsa, Kuru, Panchala, Matsya, Surasena, Assaka, Avanti, Gandhara, Kamboja, Anga, Malla.

Magadha became the most powerful: Haryanka dynasty → Shishunaga dynasty → Nanda dynasty → Maurya dynasty.

Conversion to Buddhism: After Kalinga, Ashoka embraced Buddhism under monk Upagupta.

Dhamma policies:

  • Tolerance of all religious sects
  • Welfare state: hospitals, wells, roads, trees planted
  • Officials (Dhamma Mahamattas) appointed to spread Dhamma
  • Sent missionaries: Mahendra (son) and Sanghamitra (daughter) to Sri Lanka

Decline: After Ashoka, empire fragmented. Last Mauryan emperor Brihadratha was killed by general Pushyamitra Shunga (185 BCE) — founded Shunga dynasty.


Post-Mauryan Period (185 BCE–320 CE)

  • Shunga dynasty (185–75 BCE): Brahminical revival; Sanchi stupa expansion; persecuted Buddhists
