Earth's rotation and a computation of pi

Post-Mauryan Regional Powers, the Gupta-Vakataka Age and Harsha

With the Mauryan centre gone, Unit II's second half tracks the dissolution of empire into competing regional powers — Indo-Greek, Sunga, Satavahana and Kushana — before a second imperial consolidation under the Guptas, followed in turn by Harsha's more modest seventh-century order and the lesser-known Salankayanas and Visnukundins of Andhradesa.

1. Dissolution of Empire: Indo-Greeks to Kushanas

The Indo-Greeks (descendants of Bactrian Greek settlers, Menander/Milinda the best known, remembered in the Buddhist text Milinda Panha for his dialogue with the monk Nagasena) ruled the north-west after Mauryan withdrawal; the Sungas (Pushyamitra onward) held the Gangetic heartland; the Satavahanas dominated the Deccan with a distinctive matrilineal-naming convention (kings named after their mothers) and are credited with reviving Brahmanical patronage after the Mauryan-Buddhist interlude; and the Kushanas (Central Asian in origin, Kanishka their most celebrated ruler) built a trans-regional empire linking Central Asia to the Gangetic plain, patronising Mahayana Buddhism at the Fourth Buddhist Council traditionally associated with his reign.

Sangam-age south India — contemporary Sangam literature (Tamil anthologies compiled over several centuries) records the Chera, Chola and Pandya kingdoms' polity, trade and society, giving a rare literary window onto the far south that the northern Puranic tradition does not cover in comparable detail.
Trade with the Roman world (2nd century BCE-3rd century CE) — Roman gold coin hoards found in south India, and the Periplus of the Erythraean Sea's description of ports (Muziris, Arikamedu), record a flourishing pepper-and-textile-for-gold exchange across the Indian Ocean.

⚠️ Kharavela is Kalinga, not Kushana

Kharavela of Kalinga (Hathigumpha inscription, Odisha) is a separate, contemporary regional ruler and a patron of Jainism — do not confuse him with the Kushanas' patronage of Buddhism; the syllabus lists 'Kharavela and Jainism' as its own distinct sub-item precisely to keep the two apart.

2. The Gupta-Vakataka Age

The Guptas (founded by Chandragupta I, expanded decisively by Samudragupta — whose conquests are recorded in the Allahabad Pillar inscription composed by his court poet Harisena — and consolidated by Chandragupta II 'Vikramaditya') ruled in a looser paramountcy over a network of subordinate and allied rulers (including the contemporary, matrimonially allied Vakatakas of the Deccan) rather than the Mauryan model of direct centralised control, which is exactly why the syllabus treats 'Gupta-Vakataka' as a single connected age rather than two separate topics.

Gupta age: land, religion, science
Theme	Development
Agrarian economy and land grants	Land grants to Brahmanas and temples (agraharas) grow common, often carrying fiscal and administrative immunities — an early instance of the land-rights and land-revenue questions Unit III develops at much greater length for the early medieval period proper.
Puranic Hinduism and temple architecture	The Puranas take their present form; image worship and temple building (the earliest structural stone temples — Dashavatara Temple at Deogarh) begin, alongside continuing patronage of Buddhism (Nalanda's founding is traditionally dated here) and Jainism.
Science, technology, astronomy, mathematics, medicine	Aryabhata (Aryabhatiya) proposes Earth's rotation and computes pi; the concept of zero and the decimal place-value system take mature form; Sanskrit literature flourishes (Kalidasa); the rust-resistant Delhi Iron Pillar (Chandra, likely a Gupta-era ruler) survives as metallurgical evidence.

3. Harsha and His Times

Harshavardhana of Kanauj (r. 606-647 CE), whose reign is known chiefly through his court poet Banabhatta's Harshacharita and the Chinese pilgrim Hiuen Tsang's eyewitness travel account (Si-Yu-Ki), ruled a north Indian kingdom that was, again like the Guptas, a paramountcy over subordinate rulers rather than a tightly centralised bureaucratic state — and his decisive defeat by the Chalukya king Pulakeshin II on the Narmada marks the practical southern limit of his power.

Administration — Hiuen Tsang describes light taxation, a largely non-monetised economy relying on payment in kind, and Harsha's own personal, itinerant style of governance (he is recorded touring his kingdom to dispense justice directly).
Religion — Harsha personally patronised Buddhism (the great quinquennial assembly at Prayaga and the debate/assembly at Kanauj, both recorded by Hiuen Tsang) alongside Shaivism and Sun-worship, again illustrating the era's characteristic multi-religious royal patronage rather than exclusive sectarian rule.

4. Salankayanas and Visnukundins in Andhradesa

The Salankayanas (capital Vengi, roughly 4th-5th centuries CE) and their successors the Visnukundins (5th-6th centuries CE, expanding across coastal Andhra and parts of the eastern Deccan) are the syllabus's own named regional dynasties of Andhradesa contemporary with the Gupta-Vakataka age — smaller in scale than the imperial powers this unit otherwise covers, but examinable precisely because NET names them explicitly rather than leaving them to a generic 'regional powers' label.

🎯 Why a named minor dynasty is fair game

A syllabus line that names a specific dynasty rather than a category is, on the usual reading of a syllabus, a specific commitment to test — the two Andhradesa dynasties are exactly the kind of named-but-minor detail a candidate who only studied the 'big four' (Mauryas, post-Mauryan powers, Guptas, Harsha) would miss.

Key takeaways

After Mauryan withdrawal, the Indo-Greeks (Menander/Milinda), Sungas, Satavahanas (matrilineal royal naming) and Kushanas (Kanishka, the Fourth Buddhist Council) divided the subcontinent; Kharavela of Kalinga, a Jain patron, is a separate contemporary ruler.
Sangam literature records Chera-Chola-Pandya south India; Indo-Roman trade (2nd century BCE-3rd century CE) is evidenced by Roman coin hoards and the Periplus's ports (Muziris, Arikamedu).
The Gupta-Vakataka age was a looser paramountcy (unlike direct Mauryan control); it saw growing land grants (agraharas), the beginning of structural temple architecture, and Puranic Hinduism's mature form alongside continued Buddhist/Jain patronage.
Aryabhata's astronomy/mathematics, the mature decimal place-value system and zero, and the Delhi Iron Pillar's metallurgy mark Gupta-age science; Harsha's reign is known through Banabhatta's Harshacharita and Hiuen Tsang's Si-Yu-Ki.
Harsha's defeat by Pulakeshin II on the Narmada set his southern limit; the Salankayanas and Visnukundins are the syllabus's own named Andhradesa dynasties contemporary with this age.

2. Chandragupta I
3. Chandragupta II
4. Kumaragupta
Show answer
Answer: A — Samudragupta

The Gupta system of rule over subordinate and allied kings, including the Vakatakas, is best described as:
1. A looser paramountcy rather than direct centralised control
2. An identical bureaucratic system to the Mauryas
3. Direct rule with no subordinate kings at all
4. A purely naval empire
Show answer
Answer: A — A looser paramountcy rather than direct centralised control
Unlike the tightly centralised Mauryan bureaucracy, Gupta rule worked through a network of subordinate and allied rulers, the Vakatakas among them, held together by paramountcy rather than direct administration.
Aryabhata's Aryabhatiya is chiefly notable for proposing:

3. The Gupta land-revenue system
4. The decimal calendar
Show answer
Answer: A — Earth's rotation and a computation of pi
Aryabhata proposed the Earth's rotation on its axis and computed a close approximation of pi, alongside work on trigonometry and astronomy — part of the Gupta age's wider scientific flourishing.
