"Second Urbanisation" — when + where?
After the FIRST URBANISATION of the Harappans collapsed ~1900 BCE, India had no cities for ~1,200 years (only Vedic villages). FROM ~600 BCE — IRON AGE technology + new political-economic conditions in the GANGA-YAMUNA DOAB created the SECOND URBANISATION. Cities like Pataliputra, Vaishali, Kausambi, Sravasti, Mathura, Varanasi, Ujjain, Taxila emerged with high population, walled defences, markets, coinage, scripts.
How does characterise the 16 Mahajanapadas?
(i) Listed in BUDDHIST text Anguttara Nikaya + JAIN Bhagavati Sutra; (ii) SOME were monarchies (Magadha, Kosala, Avanti, Vatsa); (iii) OTHERS were "GANA-SANGHAS" (republics) — Vajji, Malla, Kamboja; (iv) BIG FOUR fought for paramountcy (eventually MAGADHA absorbed all three); (v) Cities had WALLS, FORTS, mints, markets; (vi) FIRST INDIAN COINAGE — punch-marked silver coins.
Why did MAGADHA win? — the standard textbook 12's 6 reasons (after Sharma)?
(i) FERTILE soil of the Ganga plain → highest revenue; (ii) IRON ORE from Chotanagpur → weapons + ploughs; (iii) ELEPHANT FORESTS in eastern India → military advantage; (iv) GANGA river as trade + troop transport; (v) STRATEGIC capitals (Rajagriha hill-fort, Pataliputra at confluence); (vi) AMBITIOUS rulers (Bimbisara, Ajatashatru, Mahapadma Nanda, Chandragupta Maurya).
16 MAHAJANAPADAS — list them?
Per Buddhist Anguttara Nikaya: KASHI, KOSALA, ANGA, MAGADHA, VAJJI, MALLA, CHEDI, VATSA, KURU, PANCHALA, MATSYA, SHURASENA, ASHMAKA, AVANTI, GANDHARA, KAMBOJA. 16 great states emerged ~600 BCE in N India during 2nd urbanisation. Mostly MONARCHIES; some REPUBLICS (Vajji, Malla). Magadha eventually absorbed others → Mauryan Empire.
Second URBANISATION features?
After 1st urbanisation collapse (Harappan ~1900 BCE), 2nd urbanisation emerged ~600 BCE in GANGA-YAMUNA doab. Features: (i) IRON tools cleared forests; (ii) LARGE FORTIFIED cities — Rajagriha, Pataliputra, Kausambi, Sravasti, Ujjain; (iii) PUNCH-MARKED COINS appeared (silver + copper); (iv) Second-millennium VEDIC tradition continued; (v) Buddhism + Jainism arose in this milieu.
3 main sources for Mauryan history?
(i) ARTHASHASTRA (Sanskrit, attributed to Kautilya/Chanakya — rediscovered 1905 by R. Shamasastry); (ii) INDICA by MEGASTHENES (Greek envoy 302-298 BCE; lost; preserved in fragments by Strabo + Arrian + Diodorus); (iii) ASHOKA'S EDICTS — 33 inscriptions in PRAKRIT/Brahmi (some in NW: Aramaic + Greek). Plus PURANAS (king lists), JAIN + BUDDHIST traditions, COINS + ARCHAEOLOGY.
Emphasis on the CULTURAL DIVERSITY of Mauryan empire?
Stresses that the empire was NOT culturally uniform. Different LANGUAGES (Prakrit, Sanskrit, Greek, Aramaic — visible in edicts at Kandahar), different RELIGIONS (Buddhism, Brahmanism, Jainism, Ajivika), different ECONOMIC ZONES (Pataliputra — rice; Punjab — wheat; south — millets + spices), different POLITIES (direct rule + tributary). Innovative for its time.
Mauryan ADMINISTRATION in standard accounts?
Centralised at PATALIPUTRA; FIVE provinces (capitals: Pataliputra centre; Taxila NW; Ujjain west; Suvarnagiri south; Tosali/Dhauli east) — each governed by a royal prince. ELABORATE system of officers (mahamattas, dhamma-mahamattas, district + village-level officers). Spies (gudhapurushas) — Arthashastra describes 5 stationary + 4 wandering categories.
Why did the Maurya empire end?
Attributes decline to: (i) WEAK SUCCESSORS after Ashoka — empire too vast for them; (ii) FINANCIAL STRAIN from huge army + bureaucracy; (iii) Ashoka's PACIFISM may have weakened military culture; (iv) BRAHMANICAL REACTION to pro-Buddhist policies; (v) PROVINCES broke away (Kalinga, NW); (vi) PRESSURE from Greek successors. BRIHADRATHA (last Mauryan) was assassinated by his commander PUSHYAMITRA SHUNGA in 185 BCE.
Sources for Mauryan history?
(i) ASHOKA's ROCK + PILLAR EDICTS — most reliable contemporary source; (ii) KAUTILYA's ARTHASHASTRA — administrative treatise; (iii) Megasthenes' INDIKA (Greek ambassador, fragments survive in later writers); (iv) BUDDHIST sources (Mahavamsa, Dipavamsa, Divyavadana); (v) JAIN sources (Bhadrabahu legend); (vi) PURANAS (later compilations); (vii) ARCHAEOLOGY — Pataliputra excavations, pillar sites.
CHANDRAGUPTA + Mauryan rise?
Chandragupta Maurya (r. ~321-297 BCE) — overthrew NANDA dynasty c.321 BCE, with KAUTILYA's help. Repulsed SELEUCUS NIKATOR ~305 BCE — won territory + Macedonian princess in marriage; Seleucus sent MEGASTHENES as ambassador. Empire stretched ARABIAN SEA to BAY OF BENGAL. Per JAIN tradition, abdicated to BHADRABAHU in Karnataka, died fasting at SHRAVANABELAGOLA.
Ashoka's edicts as historical innovation?
FIRST EMPEROR in world history to inscribe his MORAL message on stones across his empire — ROCK + PILLAR + CAVE edicts (33 confirmed sites). Used the LANGUAGE OF THE PEOPLE (Prakrit) — not the elite Sanskrit. INSCRIBED in language Indians + Greeks could read (Kandahar bilingual: Greek + Aramaic). the standard textbook 12: "the edicts give us ASHOKA'S OWN VOICE — rare in any ancient world."
