Ancient India — Indus Valley Civilisation, Vedic Age, Mauryas, and Guptas

Introduction

Ancient India spans a vast chronological canvas — from the earliest traces of settled human life along the Indus and Saraswati river systems roughly five thousand years ago, through the sophisticated urban experiment of the Harappan Civilisation, the spiritual and intellectual ferment of the Vedic Age, the first great imperial state under the Mauryas, and the so-called "Golden Age" of the Guptas. For a CGPSC aspirant, this is one of the highest-yield areas of the entire General Studies syllabus, and understanding not just the facts but the logic behind them is essential for navigating the increasingly nuanced question-setting pattern the CGPSC has adopted.

A review of CGPSC question papers from 2018 onward reveals that this subtopic has generated ten questions across the years 2018, 2019, 2020, 2022, and 2024. That density — sometimes four questions in a single sitting — should immediately signal the examiner's intent: this is not peripheral content. The questions have ranged from identifying archaeological sites with specific prehistoric cultures (the Palaeolithic–Chalcolithic matching question tested in CGPSC 2022, and the Ahar/Banas culture contemporaneity question from CGPSC 2024), to the political geography of ancient capitals (Pataliputra's river boundaries, CGPSC 2020), to Gupta genealogy (the Lichchhavi connection to Samudragupta, CGPSC 2024), to Buddhist patronage across dynasties (CGPSC 2018), to the identification of scholarly works (Varahamihira's corpus, CGPSC 2022), to ancient taxation terminology (Viveet, CGPSC 2024), to Pratihara rulers like Mihir Bhoja (CGPSC 2022), and Fahien's travelogue account (CGPSC 2019).

What unites these ten questions is a clear pattern: the examiner tests specific, factual, name-and-place-and-period precision. General impressions will not suffice. You need to know that Pataliputra sits between the Ganga (north) and the Son (west), not the Champa or the Vindhyas. You need to know that Amarakosha was written by Amarasimha and is not part of Varahamihira's oeuvre. You need to know that Pushyamitra Shunga actively persecuted Buddhism rather than fostered it. You need to know that the Banas or Ahar culture of Rajasthan was contemporaneous with the Harappan Civilisation, not the Mauryas or the Guptas. And you need to know that Samudragupta — not Chandragupta I — bears the epithet "Lichchhavi-dauhitara" because the maternal-grandson relationship is what the epithet marks.

This note provides the comprehensive conceptual and factual base needed across all four epochs: the Pre-Harappan and Harappan archaeological record, the Vedic Age in both its early and later phases, the Mauryan empire and its administrative-religious legacy, and the Gupta period with its cultural efflorescence. Chhattisgarh itself possesses significant ancient archaeological sites — Sirpur (capital of the Sharabhapura-Panduvamshi kingdom, one of the finest early medieval Buddhist sites in central India), the rock-art shelters of Kabra Pahad near Raigarh (analogous to Bhimbetka, with Mesolithic and later paintings), the early historical urban settlement at Malhar (Bilaspur district, with occupation layers from c. 1000 BCE onward), and the Buddhist and Shaivite complex at Talagaon/Devrani-Jethani near Bilaspur. These CG connections are noted where relevant throughout this chapter.

For Chhattisgarh specifically, ancient history is not merely an abstract academic subject — the state's own territory was the iron-ore hinterland that powered Magadha's rise to imperial dominance, the forested "Atavika" zone that Samudragupta brought to submission, and the Buddhist heartland of the Sharabhapura-Panduvamshi kings whose monument at Sirpur still stands. The examiner is aware of this CG anchoring; future questions may blend national-level ancient history with CG-specific archaeological or historical detail.

At the end you will find a worked walkthrough of the actual CGPSC questions, a PYQ trend analysis, a high-probability prediction table, common traps, named mnemonics, and a rapid-fire revision list.

Core Concepts & Foundations

Prehistoric Age Periodisation: Indian prehistory is conventionally divided into the Palaeolithic (Old Stone Age), Mesolithic (Middle Stone Age), Neolithic (New Stone Age), and Chalcolithic (Copper-Bronze Age) phases. Each phase is defined by its dominant tool technology, subsistence strategy, and settlement character.

Palaeolithic Age (c. 500,000–10,000 BCE): The longest and earliest phase. Characterised by the use of large, roughly-flaked, unpolished stone tools — hand-axes, cleavers, and choppers. The Sohan (Soan) River valley in present-day Pakistan (near Rawalpindi) is the classic type-site for the Lower Palaeolithic chopper-chopping tool industry. Economy is exclusively hunting-gathering. Bhimbetka caves in Madhya Pradesh show human occupation from the Lower Palaeolithic, though the famous painted rock shelters are mainly Mesolithic-era. In Chhattisgarh, Kabra Pahad (Raigarh) similarly shows very old human presence.

Mesolithic Age (c. 10,000–6,000 BCE): Tool technology miniaturises into microliths — tiny, geometrically-shaped blades (trapeze, triangle, lunate) designed to be hafted in composite bone or wood handles. Bhimbetka (Raisen district, MP) is the iconic site, with over 700 painted shelters showing hunting, dancing, ritualistic, and animal-figure scenes in red ochre, white, and green. CGPSC 2022's matching question places Bhimbetka firmly in this Mesolithic category.

Neolithic Age (c. 7,000–2,500 BCE, varies by region): The "food-producing revolution" — humans shift from food-gathering to food-producing through settled agriculture and animal domestication. Tools are polished stone, pottery appears, permanent settlements form. Burzahom in Kashmir is the iconic northern Indian Neolithic site, notable for pit-dwellings (semi-underground houses), polished bone tools, and the touching custom of burying dogs alongside their masters. The Southern Neolithic (Brahmagiri, Piklihal, Sangankallu in Karnataka) has its own distinct character with ash-mounds from burning cattle-pens.

Chalcolithic Age (c. 3,000–1,500 BCE): The "Copper-Stone Age" — people begin using copper alongside stone without fully abandoning stone tools. Not to be confused with the Bronze Age (bronze requires tin alloying). The Banas (Ahar) Culture of southeastern Rajasthan is the defining Chalcolithic culture of north India outside the Harappan zone. It is contemporary with the Harappan Civilisation, a fact confirmed by CGPSC 2024.

Harappan (Indus Valley) Civilisation: A mature Bronze Age urban civilisation flourishing c. 2600–1900 BCE across the vast Indus-Saraswati river system, covering present-day Pakistan and northwestern India. It represents the earliest known urban civilisation of the subcontinent — contemporaneous with Mesopotamia and ancient Egypt but covering a larger area than either.

Vedic Age (c. 1500–600 BCE): The period of Aryan settlement, Vedic textual composition, and Vedic social formation. Divided into Early Vedic (Rigvedic, c. 1500–1000 BCE) and Later Vedic (c. 1000–600 BCE) sub-periods. The transition involves a geographic eastward shift, economic change from pastoralism to settled agriculture, and social-religious elaboration from simple nature-deity polytheism to complex ritual and philosophical traditions.

Maurya Empire (c. 322–185 BCE): The first pan-subcontinental empire, founded by Chandragupta Maurya with the strategic counsel of Kautilya/Chanakya at Pataliputra. It reached its greatest extent and intellectual florescence under Ashoka (r. c. 268–232 BCE). After Ashoka's death, the empire fragmented rapidly and was finally ended by the Brahmin general Pushyamitra Shunga around 185 BCE.

Gupta Empire (c. 319–550 CE): The "Classical Age" Indian empire, founded by Chandragupta I who married a Lichchhavi princess and assumed the title Maharajadhiraja. Expanded to subcontinental scale by Samudragupta and consolidated by Chandragupta II (Vikramaditya). Celebrated for achievements in mathematics, astronomy, literature, sculpture, and statecraft that make it the reference point for "classical" Indian civilisation.

Varahamihira (c. 505–587 CE): A brilliant polymath astronomer-astrologer-naturalist of the Gupta-post-Gupta period, associated with Chandragupta II's fabled Navaratna (nine gems) court. His three major works are the Panchasiddhantika, the Brihat Samhita, and the Brihat Jataka. Amarakosha is emphatically not his work — it is a Sanskrit noun-dictionary by Amarasimha, a different Navaratna.

Pushyamitra Shunga: The Maurya commander-in-chief who assassinated the last Maurya king Brihadratha while the latter was reviewing troops. He founded the Shunga dynasty (c. 185 BCE). Buddhist texts describe him as actively persecuting Buddhism — destroying stupas and offering bounties for monks' heads. CGPSC 2018 tested his anti-Buddhist identity.

Fahien (Faxian): A Chinese Buddhist monk who undertook a pilgrimage from China to India (c. 399–414 CE) during the reign of Chandragupta II. His account Foguoji (Record of Buddhist Kingdoms) is among the earliest surviving first-person descriptions of Gupta-era India. He specifically described charitable hospitals at Pataliputra — a detail tested directly in CGPSC 2019. Unlike Xuanzang (who followed two centuries later), Fahien travelled primarily to visit Buddhist holy sites rather than to engage with a royal court.

Kautilya (Chanakya / Vishnugupta): The Brahmin scholar-strategist who counselled Chandragupta Maurya and authored the Arthashastra — a systematic treatise on statecraft, taxation, diplomacy, and military strategy. The Arthashastra's seven-limb theory of the state (Saptanga) and its detailed taxation vocabulary (including Viveet, Bhaga, Shulka, and dozens of other terms) are rich sources for CGPSC-style precision questions.
