South Asia (964 – 1107 CE): Ghaznavids and Cholas, Palas and Senas, and the Rise of a Maritime Subcontinent

Geographic and Environmental Context

South Asia in the Lower High Medieval Age extended from the Hindu Kush and Himalayas to the southern tip of the Indian Peninsula, embracing the Indo-Gangetic Plain, Deccan Plateau, and the Indian Ocean island chainsfrom Sri Lanka to the Maldives and Chagos.
This world contained diverse ecological zones: fertile deltas (Bengal), monsoon-watered plains (Punjab, Doab, Tamil Nadu), high plateaus (Deccan), and maritime corridors that connected the Bay of Bengal, Arabian Sea, and wider Indian Ocean. Stable monsoons and abundant river systems fostered dense agrarian civilizations, while strategic mountain passes and seaways linked the region to Central Asia, the Middle East, and Southeast Asia.

Climate and Environmental Shifts

The Medieval Warm Period sustained favorable rainfall and robust agricultural production across the subcontinent.

• Bengal’s delta expanded, increasing rice cultivation.

• Deccan reservoirs and Tamil tank systems mitigated drought.

• Sri Lanka’s irrigation canals and Polonnaruwa reservoirs ensured food security.

• In the north, Himalayan passes remained open for salt-and-wool exchange, while steppe pressures introduced new migratory and military currents into Afghanistan and Punjab.
  Ecological stability thus underpinned both imperial consolidation and far-reaching commerce.

Societies and Political Developments

Northern South Asia: From Ghazni to Bengal

• Afghanistan and Punjab:
  The Ghaznavid Empire, under Mahmud of Ghazni (r. 998–1030), extended from Ghazni to the Punjab, conducting celebrated but destructive raids into India. After mid-century, the Seljuks displaced Ghaznavid power in Khurasan, leaving a Punjabi remnant.

• Delhi–Doab:
  Fragmented into Rajput strongholds—Tomaras of Delhi, Chauhans of Ajmer—defending regional autonomy through fortified cities and chivalric warfare.

• Bengal:
  The Palas revived under Mahipala I (r. 988–1038), patronizing Buddhism, but waned as the Sena dynasty(Ballala Sena, Lakshmana Sena) rose, asserting Hindu orthodoxy and moving the political center to Vikramapura.

• Kashmir prospered under Hindu–Shahi kings with temple patronage and bronze artistry.

• Nepal saw the Malla dynasty strengthen Kathmandu’s urban and temple culture; Bhutan absorbed Tibetan Buddhist diffusion, embedding monastic authority.

• Arakan and the Chindwin valley connected Bengal and Upper Burma through Buddhist polities such as Launggyet, mediating rice and elephant trade.

Maritime South Asia: The Chola Zenith and Maritime Integration

• Tamil Nadu and the Cholas:
  Under Rajaraja I (r. 985–1014) and Rajendra I (r. 1014–1044), the Chola Empire  unified the peninsula and projected naval power across the Bay of Bengal, conquering northern Sri Lanka, the Maldives, and launching expeditions toward Southeast Asia.
  Monumental Shaiva temples—notably the Brihadeshvara at Thanjavur (1010)—symbolized imperial grandeur.

• Deccan:
  The Western Chalukyas contested Chola influence; the Rashtrakutas’ legacy persisted through successor states balancing agrarian control with temple patronage.

• Kerala (Chera realm):
  Spice exports (pepper, cinnamon) enriched port towns along the Malabar Coast.

• Sri Lanka:
  The Cholas annexed the north in 993 CE, ruling from Polonnaruwa until local resurgence under Vijayabahu I (r. 1055–1110) restored Sinhalese sovereignty.

• Islands:
  The Maldives entered the Chola orbit as a node in the cowrie and coconut trades; Lakshadweep and Chagos remained lightly settled but linked to wider sea routes.

Economy and Trade

Agriculture and maritime commerce operated in symbiosis.

• Agriculture:
  Wheat and barley dominated the Punjab, rice thrived in Bengal, Nepal, and the Tamil plains, while millet and barley sustained Himalayan terraces.

• Crafts:
  Ghazni and Lahore produced ivory and fine textiles; Bengal excelled in bronze sculpture; Tamilakam specialized in cotton weaving.

• Trade Networks:

  • Overland: Horses via Kabul; textiles and indigo from North India; Himalayan salt and wool exchanged for grain.

  • Maritime: Chola fleets controlled shipping from Coromandel to Sri Lanka, the Maldives, and Southeast Asia, exporting rice, textiles, and metals, importing gold, aromatics, and ceramics.

  • Bengal’s ports (Tamralipta, Chandpur) traded rice and sugar with Arakan and Pagan Burma.

  • Malabar Coast ports supplied spices to Arab and Persian merchants; cowries from the Maldives circulated as currency across the Indian Ocean.

• Coinage: Ghaznavid silver dirhams and Chola gold fanams symbolized dual monetary spheres bridging Islamic Asia and the Indic world.

Subsistence and Technology

• Irrigation:
  Ghaznavid canals around Lahore, embankments in Bengal, and vast tank systems in Tamil Nadu and Andhra maximized monsoon use.

• Military:
  Turkish cavalry and war-elephants dominated northern battlefields; southern navies wielded catapults and fire arrows at sea.

• Architecture:
  Chola Dravidian temples, Sena Hindu shrines, Ghaznavid mosques in Lahore and Ghazni, and Nepalese pagodas expressed regional diversity.

• Artisanal technology: advanced bronze casting, stone carving, shipbuilding, and water-management engineering enriched both sacred and practical life.

Movement and Interaction Corridors

• Khyber and Bolan Passes: conduits for Central Asian caravans and invasions.

• Punjab–Doab–Bengal trunk route: horses, textiles, and tribute moved east–west.

• Bay of Bengal seaways: joined Coromandel, Sri Lanka, and Southeast Asia.

• Bengal–Arakan–Chindwin corridor: linked rice and elephant trade to Pagan Burma.

• Himalayan passes: carried salt, wool, and religious ideas between Kathmandu, Bhutan, and Tibet.

Together these routes knit the subcontinent into a single commercial and religious field reaching from Samarkand to Srivijaya.

Belief and Symbolism

South Asia’s religious landscape was plural and dynamic.

• Islam: Ghaznavid rule introduced Sunni madrasas and mosques in Punjab, with early Sufi lodges fostering intercultural dialogue.

• Hinduism: Chola and Sena patrons reinforced Shaiva and Vaishnava orthodoxy through monumental architecture and ritual kingship.

• Buddhism: persisted in Bengal, Nepal, and Kashmir; Vajrayāna centers in Bihar–Nepal transmitted teachings to Tibet, influencing the phyi dar revival.

• Jainism flourished under Chalukya and local Deccan courts.

• Sri Lanka: Theravāda continuity anchored by Polonnaruwa monasteries.

• Bhutan and Himalayan regions: integrated Tibetan Drukpa Kagyu traditions.
  Temples, stupas, and mosques alike proclaimed divine kingship and cosmological order across diverse faiths.

Adaptation and Resilience

Hydraulic engineering and ritualized redistribution enabled resilience to climatic fluctuation.

• Tank irrigation buffered drought; flood embankments protected deltas.

• Maritime trade diversified revenue beyond agrarian surplus.

• Caste and monastic networks ensured social continuity and education.

• Inter-regional diplomacy—tribute, pilgrimage, and intermarriage—helped maintain equilibrium despite warfare.
  The coexistence of Hindu, Buddhist, and Islamic polities fostered cultural synthesis rather than collapse.

Long-Term Significance

By 1107 CE, South Asia embodied a dual-centered world:

• In the north, the Ghaznavids were declining, soon to yield to Ghurid expansion; Rajput houses held the plains; Bengal transitioned from Pala Buddhist to Sena Hindu rule; and Himalayan kingdoms blended Indic and Tibetan traditions.

• In the south, the Cholas presided over the most extensive maritime empire ever forged by an Indian dynasty, while Sri Lanka regained independence and the Deccan balanced Chalukya and regional powers.

• Across both spheres, agricultural intensification, urban prosperity, and maritime connectivity positioned South Asia as a pivotal crossroads between Islamic West Asia, Southeast Asia, and East Africa.

By the early twelfth century, the subcontinent stood as a maritime–continental civilization, where temple and mosque, caravan and ship, monsoon and mountain together defined one of the world’s most intricate and enduring cultural ecologies.

Upper South Asia (964 – 1107 CE): Ghaznavids, Palas & Senas, and Himalayan Polities

Geographic and Environmental Context

Upper South Asia includes Afghanistan, Pakistan, North India, Nepal, Bhutan, Bangladesh, and northwestern Myanmar (northern Arakan/Yakhine and the Chindwin valley).

• Anchors: the Indo-Gangetic plain from Punjab to Bengal, the Kathmandu Valley, the Himalayan foothills of Nepal and Bhutan, Kashmir, and the Arakan/Chindwin corridors tying Bengal to Upper Burma.

Climate and Environmental Shifts

• Favorable monsoons persisted; Bengal deltaic expansion intensified rice cultivation.

• Himalayan passes remained viable for salt/wool–grain exchange.

• Steppe pressures brought Turkic migrations into Afghanistan.

Societies and Political Developments

• Afghanistan & Punjab:

  • Ghaznavid Empire (Mahmud of Ghazni, r. 998–1030) extended from Ghazni to Punjab, conducting raids deep into India.

  • By mid-11th c., Seljuks displaced Ghaznavids from Khurasan; Ghaznavids remained in Punjab.

• Delhi–Doab: fractured into Rajput polities; Tomaras and Chauhans controlled Delhi and Ajmer.

• Bengal:

  • Palas revived under Mahipala I (r. 988–1038) but declined by 12th c.; Sena dynasty rose (Ballala Sena, Lakshmana Sena), enforcing Hindu orthodoxy and shifting centers to Vikramapura.

• Kashmir: flourished under Hindu/Shahi kings; strong temple patronage.

• Nepal: Malla dynasty consolidated; Kathmandu Valley urbanism deepened.

• Bhutan: Buddhist diffusion from Tibet strengthened local monastic centers.

• Arakan/Chindwin: Buddhist Launggyet and related polities matured, interfacing with Bengal and Pagan Burma.

Economy and Trade

• Agriculture: wheat/barley (Punjab); rice (Bengal, Nepal); barley/millet (Himalayas).

• Crafts: Ghazni and Lahore famed for ivory and textiles; Bengal continued bronze statuary.

• Trade:

  • Horses via Kabul; cotton/textiles from North India; Bengal rice and sugar to Southeast Asia.

  • Himalayan salt, wool, and paper for Indian grain.

• Coinage: Ghaznavid silver dirhams circulated widely.

Subsistence and Technology

• Irrigation: Ghaznavid Lahore invested in canals; Bengal’s embankments; Nepalese ponds.

• Military: Ghaznavid Turkish cavalry and elephants; Rajput chivalric warfare; fortified hilltop redoubts.

• Architecture: Sena Hindu temples; Ghaznavid mosques (Lahore, Ghazni); Nepalese pagodas.

Movement and Interaction Corridors

• Khyber/Bolan passes: caravans and invasions.

• Punjab–Doab–Bengal trunk: horses, textiles, revenue flow.

• Bengal–Arakan–Chindwin: rice and elephants tied to Pagan.

• Himalayan passes: Kathmandu salt–grain, Bhutanese monastic circuits.

Belief and Symbolism

• Islam: Ghaznavids sponsored Sunni madrasas, mosques; Sufi presence began in Punjab.

• Hinduism: Rajput and Sena patrons reinforced orthodoxy.

• Buddhism: still strong in Bengal, Nepal, Kashmir; Vajrayana radiated from Bihar/Nepal to Tibet.

• Bhutan: monasteries extended Tibetan Drukpa/Kagyu reach.

Long-Term Significance

By 1107, Upper South Asia was transitioning:

• Ghaznavids fading, Ghurids poised to strike.

• Bengal shifting from Palas to Senas.

• Rajputs held Delhi–Doab.

• Nepal and Bhutan stabilized into syncretic Buddhist–Hindu realms.

• Arakan–Chindwin solidified as the link between Bengal and Pagan Burma.

The Turks and the Afghans  spearhead the Islamic conquest in India through the traditional invasion routes of the northwest,  almost three centuries after the Arab conquest of Sindh.

Mahmud of Ghazni (979-1030) leads a series of raids against Rajput kingdoms and rich Hindu temples and establishes a base in the Punjab for future incursions.

Mahmud's tactics originate the legend of idol-smashing Muslims bent on plunder and forced conversions, a reputation that persists in India to the present day.

The wandering of the so-called Gypsies, or Romani, of North India begins at approximately this time.

The absence of a written history has meant that the origin and early history of the Romani people was long an enigma.

Linguistic evidence indicates the Romanies originated from the Rajasthani people, emigrating from India towards the northwest no earlier than the eleventh century.

Contemporary populations sometimes suggested as sharing a close relationship to the Romani are the Dom people of Central Asia and the Banjara of India.

Genetic evidence connects the Romani people and the Jat people, the descendants of groups that emigrated from India towards Central Asia during the medieval period.

There are serological similarities shared with several populations that linked the two people in a 1992 study.

A limited medical survey of haplotypes frequently found in the Jat Sikhs and Jats of Haryana, and those found in the Romani populations revealed no matches in 2007.

However, in 2009 researchers discovered the "Jat mutation", which causes a type of glaucoma in Romani people.

The cause of the Romani diaspora is unknown.

However, the most probable conclusion is that the Romanies were part of the military in North India.

When there were repeated raids by Mahmud of Ghazni and these soldiers were defeated, they were moved west with their families into the Eastern Roman Empire.

Sultan Mu'izz al-Din Muhammad of Ghor had proceeded in 1191 towards Hindustan through the Khyber Pass in modern day Pakistan and was successful in reaching Punjab.

Mu'izz had captured a fortress, Bathinda in present-day Punjab state on the northwestern frontier of Prithvīrāj Chauhān's kingdom.

After appointing a Qazi Zia-ud-Din as governor of the fortress, he had received the news that Prithviraj's army, led by his vassal prince Govind Tai, were on their way to besiege the fortress.

The two armies eventually met near the town of Tarain, 14 miles from Thanesar in present-day Haryana.

The Ghorid army had initiated battle by attacking with cavalry, launching arrows at the Rajput center.

The Chauhanid forces had counterattacked from three sides and dominated the battle, pressuring the Ghorid army into a withdrawal.

Meanwhile, Mu'izz al-Din had been wounded in personal combat with Govind Tai.

The Chauhanid forces did not pursue the Ghorid army, either not wanting to invade hostile territory or misjudging Ghori's ambition, and electing instead to retake the fortress of Bhatinda.

On his return to Ghazni, Mu'izz al-Din had made hectic preparations to avenge the defeat.

On reaching Lahore, he had sent his envoy to Prithviraj to demand his submission, but the Chauhan ruler had refused to comply.

Seeing through the Ghorid stratagem, Prithviraj had issued a fervent appeal to his fellow Rajput chiefs to come to his aid against the Muslim invader.

About one hundred and fifty of them respond favorably but Mu'izz al-Din, upon hearing this news, had sent a letter asking for a truce in order to deceive Prithviraj.

Mu'izz al-Din now re-attacks Prithiviraj with a stronger army.

Prithviraj had called his banners (other Rajputs under him or his allies) but hopes to buy time for his banners to arrive.

Mu'izz al-Din gets wind of this and deceitfully sends a letter to Prithviraj for truce, then attacks the Rajput army before dawn.

The Rajput tradition is to fight from sunrise to sunset.

Although they are able to quickly form formations, they suffer losses due to the unexpected attack.

The Rajput army is eventually defeated and Prithviraj, under whom the Chauhana dynasy, has reached its greatest extent, is taken prisoner and subsequently executed.

The state of Ajmer fails to fulfill the tribute demands as per the custom after a defeat; as a consequence, Qutb-ud-din Aibak in 1193 takes over Ajmer and soon establishes Ghurid control in northern and central India.

Rajput kingdoms such as Saraswati, Samana, …

…Kohram and Hansi are captured without any difficulty.

The forces of Qutb-ud-din Aibak finally advance on Delhi, capturing it soon after the Battle of Chandwar(modern Firozabad), on the Jumna River close to Agra, a surprise attack on Raja Jaichand of Kannauj.

Mu'izz ad-Din returns west to Ghazni to deal with the threat to his western frontiers from the unrest in Iran, but he appoints Aibak as his regional governor for northern India, using Delhi as a base to further enlarge his growing empire.
