SMART NOTES FOR UPSC CSE & UPPCS (MODULE 01 OF 15)
🧭 OVERVIEW & EXAM CONTEXT
The prehistoric period covers human history before the invention of writing, reconstructed entirely through archaeology—stone tools, pottery, skeletal remains, and cave art—rather than textual records. In India, prehistory extends from the appearance of early homanin stone tools over 1.5 million years ago down to the rise of literate, urban metal-using societies like the Harappan Civilization. Prehistory is conventionally organized through the Three-Age System (Stone, Bronze, and Iron Ages), encompassing the Palaeolithic, Mesolithic, Neolithic, Chalcolithic, and Megalithic eras.
🔥 Key Archaeological Pioneers
Robert Bruce Foote: Regarded as the "Father of Indian Prehistory"—discovered the first Palaeolithic tool in India at Pallavaram, Madras in 1863.
V.D. Krishnaswami & H.D. Sankalia: Systematized Stone Age typology and stratified site excavations in post-independence India.
1. 🪓 Palaeolithic Age (Old Stone Age)
Timeline: c. 2,000,000 BCE – 10,000 BCE (coincides with the geological Pleistocene / Ice Age)
Characterized by unpolished, crude chipped stone tools made of hard quartzite rock (hence Palaeolithic humans are termed "Quartzite Men"). People lived as nomadic hunter-gatherers with no knowledge of agriculture, pottery, or permanent housing. Based on tool typology and climatic shifts, it is divided into three distinct phases:
Tool Industry: Shift from heavy core hand-axes to smaller flake-based tools: scrapers, borers, blades, and points.
Excavation Benchmark: Based largely on H.D. Sankalia's work at Nevasa.
Key Sites:Nevasa (Maharashtra); Bhimbetka (MP); Belan Valley (UP); Luni Valley (Rajasthan).
1.3 Upper Palaeolithic (c. 40,000 – 10,000 BCE)
Hominin Association: Coincides with the arrival of Homo sapiens and the closing phase of the Ice Age.
Tool Industry:Blades and burins; emergence of bone tools, needles, and harpoons.
Key Sites:Bhimbetka rock shelters; Belan Valley (UP); Renigunta & Muchchatla Chintamanu Gavi (AP).
🔥 Benchmark World Heritage Site
Bhimbetka Rock Shelters (Raisen, MP) is a UNESCO World Heritage Site featuring continuous occupation evidence from Lower Palaeolithic through historical times, famous for early Mesolithic rock paintings.
2. 🏹 Mesolithic Age (Middle Stone Age)
Timeline: c. 10,000 BCE – 6,000 BCE
A crucial transitional phase coinciding with the onset of the Holocene Epoch, where warmer climate led to expanded forests and game animals. Marks the shift from pure food-gathering toward early animal husbandry.
Microliths: Tiny, geometric stone tools (1 cm to 5 cm; crescents, triangles, trapezes) hafted onto bone or wood handles to build composite arrows, spears, and sickles.
Animal Domestication: Dogs were the earliest domesticated animals; cattle, sheep, and goat bones appear at settlement sites.
Burial Rituals: Deliberate grave burials with body orientation and grave offerings show early concepts of an afterlife.
Rock Art: Hunting, dancing, and communal scenes painted at Bhimbetka belong primarily to this phase.
Key Sites:
Bagor (Rajasthan)—Largest and best-documented Mesolithic site on the Kothari river.
Adamgarh (Madhya Pradesh)—Earliest definitive evidence of animal domestication alongside Bagor.
Langhnaj (Gujarat)—Yields human skeletons and microliths.
Sarai Nahar Rai & Mahadaha (UP)—Yield hearths, joint human burials, and bone ornaments.
3. 🌾 Neolithic Age (New Stone Age)
Timeline: c. 7,000 BCE – 1,000 BCE (varies significantly across regions)
Coined by V. Gordon Childe as the "Neolithic Revolution"—the fundamental turning point in human history where societies shifted from hunting-gathering to food production through farming and permanent village settlements.
Agricultural Breakthrough: Wheat and barley in the northwest; rice in the Belan/Ganga Valley; millets in South India.
Polished Stone Industry: Ground and polished stone celts, axes, and adzes with sharp cutting edges.
Permanent Settlements: Mud-brick huts, wattle-and-daub houses, and underground pit-dwellings.
Pottery Evolution: Early handmade pottery evolving into wheel-made corded and burnished ware for grain storage.
Textiles: Early evidence of cotton and wool spinning/weaving.

Archaeological Significance
Mehrgarh
Baluchistan (Pakistan)
Earliest known agricultural settlement in South Asia (c. 7000 BCE); precursor to Harappan culture.
Burzahom & Gufkral
Kashmir Valley
Subterranean pit-dwellings; coarse grey pottery; practice of burying dogs with human owners.
Koldihwa & Mahagara
Belan Valley (UP)
Earliest evidence of rice cultivation and domesticated cattle in India.
Chirand
Saran (Bihar)
Remarkable density of polished bone and antler tools.
Piklihal, Utnur, Maski
Deccan / Karnataka
Neolithic "Ash Mounds" created by accumulated, burned cattle dung inside enclosures.
Brahmagiri
Karnataka
Type-site establishing South Indian Neolithic-to-Chalcolithic stratigraphy.
4. 🔶 Chalcolithic Age (Copper-Stone Age)
Timeline: c. 2,000 BCE – 700 BCE
The first metal-using phase where communities used copper alongside stone tools. Because copper was scarce, stone microliths remained widespread. These were non-urban, non-Harappan agrarian rural cultures.
Diagnostic Pottery:Black-and-Red Ware (BRW) painted with white geometric designs.
Housing Pattern: Rectangular or circular mud huts; no planned urban grid layout.
Burial Customs: Habitation-floor burials (under house floors); urn burials in South/Central India.
Major Regional Chalcolithic Cultures:
Ahar-Banas Culture (Southeastern Rajasthan—Ahar/Gilund): Specialized in copper smelting; copper flat axes and bangles.
Kayatha Culture (Chambal Valley, MP): Fine sturdy pottery; copper bangles and steatite bead hoards.
Jorwe Culture (Maharashtra—Inamgaon, Daimabad): Most widespread; Daimabad yields famous solid bronze sculptures (chariot, rhino, elephant, buffalo).
5. ⚒️ Iron Age / Megalithic Culture
Timeline: c. 1,500/1,000 BCE onwards
The introduction of iron metallurgy revolutionized agriculture and warfare by enabling deep forest clearing and heavy ploughing. In North India, the Iron Age coincides with Painted Grey Ware (PGW) associated with Later Vedic sites (Hastinapur, Atranjikhera). In Peninsular India, it is represented by Megalithic Burial Structures.
Peninsular Megalithic Burials:
"Megalith" refers to monuments constructed using large unhewn stones, concentrated across South India, Maharashtra, and Central India. They contain skeletal remains, Black-and-Red Ware, and iron weapons (swords, daggers, sickles).
Benchmark Sites:Hallur & Brahmagiri (Karnataka—Hallur yields some of the earliest iron artifacts c. 1000 BCE); Adichanallur (Tamil Nadu—extensive urn burial site); Kodumanal (TN).
