South Asia (1396–1539 CE)

Sultanates, Temple-States, and the Monsoon World on the Eve of Cannon Empires

Geography & Environmental Context

South Asia in this age comprised two interlocking spheres.
Northern South Asia included Afghanistan, Pakistan, northern India, Nepal, Bhutan, Bangladesh, and northwestern Myanmar (the Arakan/Yakhine littoral and Chindwin valley)—a corridor from the Hindu Kush and Khyber gateways across the Indus and Ganges–Yamuna basins to the Brahmaputra delta and the Arakan coast.
Southern South Asia encompassed southern India, Sri Lanka, the Maldives, Lakshadweep, and the Chagos Archipelago—from the Deccan plateau and the Krishna–Tungabhadra–Kaveri valleys to the Coromandel and Malabar shores and the coral atolls of the central Indian Ocean.
Monsoon-fed plains, terraced Himalayan hills, pepper and cinnamon coasts, and atoll seas together formed one of the early modern world’s most diverse ecological mosaics.

Climate & Environmental Shifts

The Little Ice Age heightened variability:

• Western disturbances brought deeper winter snows to the Hindu Kush and pulses of rain to the Indus basin.

• The summer monsoon oscillated sharply, producing Ganges–Brahmaputra flood years followed by shortfalls that stressed rice and wheat belts.

• Himalayan glaciers advanced in pulses, modulating river regimes; Tarai malarial wetlands waxed and waned.

• In the south, the Southwest Monsoon fed Malabar’s pepper gardens, the Northeast Monsoon irrigated Coromandel fields; droughts struck the Deccan and Sri Lanka’s dry zone; atolls faced erratic winds, tuna swings, and cyclones.

Subsistence & Settlement

• Indus–Gangetic core: Wheat, barley, and pulses dominated the west; rice, sugarcane, and jute anchored the east. Sultanate irrigation (canals, nadi diversions) complemented long-lived village tanks in the doabs.

• Afghanistan & northwest uplands: Orchard–grain valleys (wheat, vines, pomegranates) paired with transhumant herds and caravan towns on the Kabul–Peshawar route.

• Nepal & Bhutan: Terrace rice in middle hills; millet, buckwheat, and barley higher up; yak–sheep transhumance; salt–grain exchange over the passes.

• Bengal delta: Intensive wet-rice, fishponds, and palm groves supported dense levee settlements.

• Arakan littoral & Chindwin valley: Rice coasts and shifting cultivation under the rising kingdom of Mrauk U(founded 1430), a mediator between Bengal and the Bay of Bengal.

• Deccan & peninsular India: Under Vijayanagara, irrigated rice, millets, and pulses flourished; coastal spice gardens thrived.

• Sri Lanka: Kotte in the southwest and Jaffna in the north organized rice, coconut, and cinnamon.

• Maldives & Lakshadweep: Coconuts, tuna, and imported rice sustained atolls; dried tuna (mas huni) and cowries circulated widely. Chagos remained uninhabited, yet entered pilots’ lore.

Technology & Material Culture

• Hydraulics & fields: Sultanate canals, village tanks, Persian wheels; terrace walls in the Himalaya and Sri Lanka’s reservoirs stabilized yields.

• Courtly landscapes: Fortified citadels, ribbed domes, and chahar-bāgh gardens inscribed Persianate aesthetics across the plains; in the south, stone temples, soaring gopuram gateways, bronzes, and manuscript ateliers flourished under Vijayanagara.

• Textiles & metalwork: Bengal’s cottons and fine metal casting; pepper trellises on Malabar; coral-stone mosques in the Maldives; shipyards from Calicut to Cochin.

• Scripts & paper: Paper mills and scriptoria multiplied Persian and vernacular manuscripts; temple workshops copied śāstra and puranic lore; island chronicles (tarikh) recorded dynasties.

Movement & Interaction Corridors

• Khyber & Bolan passes: Funneled Central Asian contingents—Timur’s catastrophic raid (1398) and, later, Bābur’s Timurid thrusts into the Punjab.

• Trunk roads & waterways: Grand-Trunk–style arteries linked Lahore–Delhi–Agra–Varanasi to Bengal river ports; caravanserais and market towns proliferated.

• Himalayan routes: Salt, wool, and metalware moved between Tibet, Nepal, Bhutan, and the plains; monastic and royal courts managed passes.

• Indian Ocean circuits: Calicut, Cochin, and Colombo served Arab, Gujarati, and Chinese merchants; horses, textiles, and silver moved in, pepper, cardamom, cinnamon, pearls, and elephants out.

• Atoll chains: Maldives supplied cowries and dried fish; Lakshadweep bridged Kerala to the central ocean; Chagos marked reefs on charts.

• Portuguese entry: Vasco da Gama at Calicut (1498); Goa seized (1510); forts at Cochin, Colombo, and Malacca (1511) reoriented sea-lanes.

Cultural & Symbolic Expressions

• Persianate–Indic synthesis: Under the Delhi Sultanate and successor houses (Jaunpur, Malwa, Gujarat), mosque complexes, madrasas, and Sufi hospices flourished; qawwali, Persian poetry, and vernacular bhaktispread in parallel; shared shrine circuits and urs feasts mediated urban and rural worlds.

• Himalayan courts: Malla polities in Nepal patronized thangka painting, scholastic lineages, and festival calendars; Bhutanese monastic states fused ritual and rule.

• Coastal kingdoms: Vijayanagara courts sponsored temple dance (Bharatanatyam), court poetry, and merchant guilds; Kotte and Jaffna balanced Buddhist and Hindu forms.

• Atolls: Islamic devotion structured Maldives and Lakshadweep—coral mosques, Quran schools, and royal tarikh—adapted to maritime lifeways.

Environmental Adaptation & Resilience

• Field rotations: Wheat–pulse and paddy–legume cycles sustained soil; flood-recession rice and raised beds in Bengal buffered deluge and drought.

• Terraces & forests: Stone walls and shelter belts stabilized Himalayan slopes; transhumance staggered herds by elevation and season.

• Tank systems: Check-gates and storage in the Deccan and Sri Lanka mitigated failure years.

• Atoll strategies: Diversified coconut–tuna economies, cisterns, and inter-island exchange underwrote fragile ecologies.

• Institutional relief: Waqf/devadāna lands provisioned monasteries, mosques, and temples that dispensed grain; village banks and merchant credit smoothed shocks.

Technology & Power Shifts (Conflict Dynamics)

• Sultanate fracture & Timurid shock: Timur’s sack of Delhi (1398) shattered central authority; regional houses rose as the Delhi court recovered fitfully.

• Timurid–Mughal advent: Bābur seized Kabul (1504), then Panipat (1526), founding the Mughal polity; consolidation followed at Khanwa (1527) and Chanderi (1528), as Rajput houses bargained war and marriage.

• Arakanese hinge: Mrauk U (from 1430) linked Bengal to Myanmar’s coasts, sheltering Muslim refugees and traders and projecting power across the Kaladan and Chindwin valleys.

• Vijayanagara zenith: Under rulers like Krishnadevaraya (r. 1509–1529), the empire contested Bahmani successors, fielding fortified cities and massed armies.

• Portuguese shock: Goa (1510) became the Estado da Índia headquarters; forts at Cochin, Colombo, and Malacca inserted cannon into monsoon politics; raids touched the Maldives and mapped Chagos.

Transition (to 1539 CE)

By 1539, South Asia balanced old orders and new horizons.
In the north, Timurid–Mughal beginnings met sultanate polities in the plains, Malla courts in the Himalaya, and Mrauk U on the Bengal–Arakan hinge.
In the south, Vijayanagara shone in temple and tank, even as Portugal’s forts and fleets rewired Indian Ocean trade.
Across deltas, passes, and atolls, resilience rested on irrigation, redistribution, and diaspora networks—an ecologically diverse monsoon world standing at the threshold of gunpowder empire and global convergence.

Upper South Asia (1396–1539 CE): Sultanates, Mountain Kingdoms, and Arakanese Gateways

Geographic & Environmental Context

The subregion of Upper South Asia includes Afghanistan, Pakistan, northern India, Nepal, Bhutan, Bangladesh, and northwestern Myanmar (the northern Arakan/Yakhine sector and the Chindwin valley). Anchors included the Hindu Kush and Khyber gateways, the Indus and Ganges–Yamuna basins, the Tarai and Himalayan hills, the Brahmaputra delta, and the Arakan coast with its river valleys (Kaladan, Chindwin). This corridor linked Central Asia to the Indo-Gangetic plain and the Bay of Bengal through Bengal–Arakan exchanges.

Climate & Environmental Shifts

The Little Ice Age brought cooler temperatures and heightened climate variability. Western disturbances delivered winter snows to the Hindu Kush and rains to the Indus basin; the summer monsoon fluctuated, producing flood years on the Ganges and Brahmaputra followed by shortfalls that stressed rice and wheat zones. Himalayan glaciers advanced in pulses, affecting river regimes; in the Tarai, malarial wetlands waxed and waned with rainfall.

Subsistence & Settlement

• Indus–Gangetic plains: Wheat, barley, and pulses in the west; rice, sugarcane, and jute in the east. Irrigation by canals and nadi diversions expanded around sultanate centers; village tank systems persisted in the doabs.

• Afghanistan and northwest uplands: Oasis and valley farming (wheat, orchards, vines) combined with transhumant herding of sheep, goats, and horses; caravan towns thrived on the Kabul–Peshawar route.

• Nepal and Bhutan: Terrace agriculture of rice (middle hills), millet, buckwheat, and barley (higher zones); pastoral yak and sheep herding on alpine pastures; salt–grain exchange across passes.

• Bengal delta: Intensive wet-rice cultivation, fishponds, and palm groves supported dense settlement along levees and backswamps.

• Northwestern Myanmar: Rice farming in the Arakan littoral and shifting cultivation in the Chindwin valley supported Arakanese states. The Kingdom of Mrauk U (founded 1430) became a major power, mediating between Bengal, the Bay of Bengal, and inland valleys. Muslim refugees and traders from Bengal enriched its cosmopolitan court..

Technology & Material Culture

Persianate hydraulics and sultanate canal-building complemented village tanks; Persian wheels lifted water in the doabs. Fortified stone and brick citadels, ribbed domes, and chahar-bagh gardens marked courtly landscapes. Paper mills and scriptoria expanded Persian and vernacular manuscript culture; coinage reforms standardized silver and copper issues. In the hills, dry-stone terrace walls, timber monasteries, and metalwork (bells, ritual objects, blades) anchored local craft ecologies; Bengal excelled in cotton textiles and fine metal casting.

Movement & Interaction Corridors

• Khyber and Bolan passes: Funneled Central Asian contingents: Timur’s invasion (1398) devastated Delhi; later Turkic–Mongol lineages probed the plains.

• Grand Trunk–style trunk roads: Linked Lahore–Delhi–Agra–Varanasi to Bengal river ports; caravanserais and market towns multiplied.

• Himalayan trade paths: Carried salt, wool, and metalware between Tibet, Nepal, and the Gangetic plains; Bhutan’s passes tied monastic polities to Assam and Bengal.

• Delta waterways: The Ganges–Brahmaputra arterial network moved rice, jute, and textiles from the interior to coastal entrepôts.

Cultural & Symbolic Expressions

Persianate court culture flourished under the Delhi Sultanate, blending with Indic forms in mosque complexes, madrasas, and Sufi hospices; qawwali, Persian poetry, and vernacular bhakti spread in parallel. In the Himalaya, Buddhist and Vajrayana monasteries patronized thangka painting, scholastic lineages, and festival calendars; Hindu shrines and royal cults thrived in Nepal’s Malla courts. In the plains, bhakti saints and Sufi pirs localized universal ideals—shared shrine circuits and urs feasts mediated social worlds in towns and villages. Bengal’s mosques and temples integrated terracotta reliefs, signaling interlaced aesthetic idioms.

Environmental Adaptation & Resilience

Farmers rotated wheat–pulses and paddy–legumes, used flood-recession rice and raised-bed cultivation in the delta, and relied on tanks and canal check-gates in drought years. Terrace walls and forest belts stabilized Himalayan slopes; transhumant routes staggered herds across elevations. Monasteries, mosques, and temples held waqf/devadana lands that provisioned relief in dearth; village grain banks and merchant guild credit buffered shortfalls.

Technology & Power Shifts (Conflict Dynamics)

Timur’s sack of Delhi (1398) fractured sultanate authority; regional houses (Jaunpur, Malwa, Gujarat) rose across the fifteenth century as the Delhi court recovered fitfully. In Afghanistan and the northwest, Babur—a Timurid prince—seized Kabul (1504), probing the Punjab via Panipat (1526) to found the Mughal polity, then consolidated at Khanwa (1527) and Chanderi (1528). Bengal maintained semi-autonomy with powerful governors; Rajput houses bargained war and marriage with rising Mughals; in the hills, Nepal’s Malla kingdoms and Bhutanese monastic states managed succession and pass politics amid Tibetan currents.

Transition

By 1539 CE, Upper South Asia balanced Timurid–Mughal beginnings in the northwest with Sultanate polities in the plains, Malla courts in Nepal, and the Arakanese kingdom of Mrauk U linking Bengal to Myanmar’s coasts.

As Muslims extend their rule into southern India, only the Hindu kingdom of Vijayanagar remains immune (until it too falls in 1565).

There are also kingdoms independent of Delhi in the Deccan, Gujarat, Malwa (central India), and Bengal.

Nevertheless, almost all of the area in present-day Pakistan remains generally under the rule of Delhi.

The Delhi sultans' failure to hold securely the Deccan and South India results in the rise of competing southern dynasties: the Muslim Bahmani Sultanate (1347-1527) and the Hindu Vijayanagar Empire (1336-1565).

Zafar Khan, a former provincial governor under the Tughluqs, had revolted against his Turkic overlord and proclaimed himself sultan, taking the title Ala-ud-Din Bahman Shah in 1347.

The Bahmani Sultanate, located in the northern Deccan, lasts for almost two centuries, until it fragments into five smaller states in 1527.

The Bahmani Sultanate adopts the patterns established by the Delhi overlords in tax collection and administration, but its downfall is caused in large measure by the competition and hatred between deccani (domiciled Muslim immigrants and local converts) and paradesi (foreigners or officials in temporary service).

The Bahmani Sultanate initiates a process of cultural synthesis visible in Hyderabad, where cultural flowering is still expressed in vigorous schools of deccani architecture and painting.

The empire of Vijayanagar (named for its capital Vijayanagar, "City of Victory," in present-day Karnataka), founded in 1336, had expanded rapidly toward Madurai in the south and Goa in the west and exerts intermittent control over the east coast and the extreme southwest.

Vijayanagar rulers closely follow Chola precedents, especially in collecting agricultural and trade revenues, in giving encouragement to commercial guilds, and in honoring temples with lavish endowments.

Added revenue needed for waging war against the Bahmani sultans is raised by introducing a set of taxes on commercial enterprises, professions, and industries.

Political rivalry between the Bahmani and the Vijayanagar rulers involves control over the Krishna-Tunghabadhra river basin, which shifts hands depending on whose military is superior at any given time.

The Vijayanagar rulers' capacity for gaining victory over their enemies is contingent on ensuring a constant supply of horses—initially through Arab traders but later through the Portuguese—and maintaining internal roads and communication networks.

Merchant guilds enjoy a wide sphere of operation and are able to offset the power of landlords and Brahmans in court politics.

Commerce and shipping eventually pass largely into the hands of foreigners, and special facilities and tax concessions are provided for them by the ruler.

Arabs and Portuguese compete for influence and control of west coast ports, and, in 1510, Goa passes into Portuguese possession.

The death of Vijayanagara’s capable ruler Tuluva Narasa Nayaka in 1503 had resulted in feudatories rising in rebellion throughout the empire.

Tuluva Narasa Nayaka’s eldest son, rules two years before being assassinated.

Vira Narasimha Raya, the next eldest son, succeeds his brother in 1505 and spends all of his four year reign fighting rebel warlords.

Following his death, apparently from illness, his younger half-brother Krishna Deva Raya is crowned on July 26, 1509, the date that the birth of the Hindu God Krishna is celebrated.

The rule of Krishna Deva Raya marks a period of much military success in Vijayanagara history.

On occasion, the king is known to change battle plans abruptly and turn a losing battle into victory.

The first decade of his rule is one of long sieges, bloody conquests and victories.

He reorganizes the army and recruits troops from several south Indian communities in order to make his cavalry more efficient.

His main enemies are the Bahmani Sultans (who, though divided into five small kingdoms, remain a constant threat), the Gajapatis of Odisha, who have been involved in constant conflict since the rule of Vijayanarara emperor Saluva Narasimha Deva Raya, and the Portuguese, a rising maritime power that is rapidly gaining control of much of the sea trade.

The feudal chiefs of Ummattur, the Reddys of Kondavidu and the Velaas of Bhuvanagiri, who have rebelled against Vijayanagar rule are conquered and subdued.

The annual raid and plunder of Vijayanagar towns and villages by the Deccan sultanates will come to an end during the Raya's rule.

He defeats the last remnant of the Bahmani Sultanate, precipitating its collapse.

In 1509 Krishnadevaraya's armies clash with the Sultan of Bijapur at Diwani and the Sultan Mahmud is severely injured and defeated.

Yusuf Adil Shah is killed and the fertile Raichur Doab triangle is annexed.

Taking advantage of the victory and the disunity of the Bahamani Sultans, the Raya invades Bidar, Gulbarga and Bijapur and earns the title "founder of the Yavana kingdom" when he releases Sultan Mahmud and makes him de facto ruler.

The title advertises the boast that he is now the political arbiter of all the Deccan.

The Sultan of Golconda, Sultan Quli Qutb Shah, is defeated by Timmarusu, Krishna Deva Raya’s prime minister.

The Bahmani dynasty believes that they descend from Bahman, a legendary king of Iran.

The Bahamani Sultans are patrons of the Persian language, culture and literature, and some members of the dynasty had become well-versed in that language and composed its literature in that language.

The most important personality of the Bidar period of the Bahmani sultanate was Mahmud Gawan, who served several sultans as prime minister and general from 1461 to 1481.

He had reconquered Goa, which had been captured by the rulers of Vijayanagar, thereby extending the sultanate from coast to coast.

Gawan also introduced remarkable administrative reforms and controlled many districts directly, thus very much improving the state’s finances, but his competent organization ended with his execution, ordered by the sultan as the result of a court intrigue.

After realizing his mistake, the sultan drank himself to death within the year, thus marking the beginning of the end of the Bahmani sultanate.

After Gawan’s death the various factions at the sultan’s court had begun a struggle for power that ends only with the dynasty itself: indigenous Muslim courtiers and generals are ranged against the ‘aliens’—Arabs, Turks and Persians.

The last sultan, Mahmud Shah, no longer has any authority and has presides over the dissolution of his realm as Sri Krishnadevaraya of Vijayanagar defeats the last remnant of Bahmani power.

The governors of the four most important provinces had declared their independence from the Bahmani ruler one after another: Bijapur (1489), Ahmadnagar (1490), Berar (1490), Bidar (1492) and Golconda (1512).

Although the Bahmani sultans will live on in Bidar until 1527, they are mere puppets in the hands of the real rulers of Bidar, the Barid Shahis, who use them so as to put pressure on the other usurpers of Bahmani rule.

The Bidar Sultanate was founded in 1492 by Qasim Barid, a Turkmen from Georgia who had joined the service of the Bahmani sultan Muhammad Shah III.

Beginning his career as a sar-naubat, he later became the mir-jumla (prime minister) of the Bahmani sultanate and during the reign of Mahmud Shah became the de facto ruler.

After his death in 1504, his son Amir Barid became the prime minister and controlled the administration of the Bahmani sultanate.

The city of Vijayapura owes much of its greatness to Yusuf Adil Shah, the founder of the independent state of Bijapur.

Ruled by the kings of the Adil Shahi dynasty, Bijapur has proved to be the most expansive of the successor states to Bahmani.

Embroiled in incessant fighting on the Deccan, …

…Bijapur had lost Goa to the Portuguese in 1510 and has been unable to regain this port.

Quli Qutb Shah, a Turkmen from Hamadan, had migrated to Delhi with some of his relatives and friends in the beginning of the sixteenth century, later migrating south to the Deccan and serving the Bahmani sultan.

After the disintegration of the Bahmani Sultanate into the five Deccan sultanates, he had declared independence in 1512 and taken the title Qutb Shah, establishing the Qutb Shahi dynasty of Golconda.
