Regional Sultanates of India

The Regional Sultanates of India^[a][1] were the independent Muslim kingdoms that existed in various regions of the Indian subcontinent from the 14th century to the 16th century. These kingdoms broke away from the Delhi Sultanate under the Tughluq dynasty, especially due to the weak reinforcement of the Sultans.^[2][3] The total number of kingdoms in this period varies, with the most common being ten; Kashmir, Madurai, Deccan, Sindh, Bengal, Khandesh, Jaunpur, Gujarat, Malwa and Multan. While some of the kingdoms faced Hindu reconquest, the majority of them were taken over by the Mughal emperors through invasion in the 16th century.^[4]

The weakening of the Delhi Sultanate stemmed from a series of ambitious but poorly executed policies under Muhammad bin Tughluq (r. 1325–1351), including the forced relocation of the capital to Daulatabad, the introduction and subsequent abandonment of token currency, punitive taxation in the Doab that triggered famines and revolts, and overambitious military campaigns that overstretched resources. These measures eroded central authority, provoked widespread provincial rebellions, and led to the de facto loss of southern territories even before his death in 1351. His successor, Firuz Shah Tughluq (r. 1351–1388), pursued a more conservative and religiously oriented administration, reviving the Iqta system in ways that strengthened local nobles at the expense of the centre, while largely abandoning efforts to recover lost provinces and focusing instead on internal consolidation and public works. This decentralisation, though stabilising in the short term, further diminished the sultanate's ability to enforce unity.

The sack of Delhi by Timur in December 1398 marked a catastrophic turning point. Amid a civil war between rival Tughluq claimants, Timur's forces defeated the Delhi army, subjected the city to a brutal multi-day massacre and plunder, and withdrew with vast loot, leaving the sultanate in ruins and its prestige irreparably damaged. The resulting power vacuum enabled provincial governors and ambitious local leaders to declare full sovereignty, giving rise to a constellation of independent Muslim-ruled sultanates across northern, eastern, western, and southern India. This period of regional autonomy, lasting roughly from the mid-14th to the late 16th century, represented both the fragmentation of the earlier imperial structure and a phase of vigorous local state-building, cultural patronage, and economic development, until most of these polities were progressively absorbed into the Mughal Empire under Babur, Humayun, and especially Akbar.

During the Tughluq dynasty, the Delhi Sultanate experienced a series of administrative and military developments that led to the loss of central control over its provinces. Muhammad bin Tughluq, who ruled from 1325 to 1351, extended the sultanate to its maximum territorial extent, reaching from the Himalayas in the north to the Krishna River in the south and from Gujarat in the west to Bengal in the east. In 1327, he ordered the transfer of the capital from Delhi to Daulatabad (formerly Devagiri) in the Deccan to improve administration of the southern territories. The move required the relocation of the royal court, administrators, scholars, and a large part of the population of Delhi. Many died during the journey from hardship, disease, and exhaustion. After a few years, the capital was shifted back to Delhi, but the episode caused lasting resentment and disrupted administrative continuity.

Firuz Shah Tughluq, who ruled from 1351 to 1388, succeeded Muhammad bin Tughluq and adopted different policies. He constructed irrigation canals, founded new towns including Hisar and Firozabad, built hospitals, and repaired earlier monuments. In administration, he made Iqta assignments largely hereditary, increased salaries for nobles and officials, ended rigorous audits and severe punishments, and expanded the royal slave establishment to approximately 180,000 persons. These changes reduced central oversight and strengthened the position of provincial governors and local nobles. On religious matter, he reimposed the Jizya tax on non-Muslims, including Brahmins, ordered the destruction of certain temples and idols, and took action against Shia and other sects considered heretical by the orthodox ulema. He launched two extended campaigns against Bengal but failed to re-establish direct control.

To fund military expeditions, the sultan increased land revenue demands in the fertile Doab region between the Ganges and Yamuna rivers. A severe drought in the 1330s caused crop failure and famine. Peasants abandoned villages, and revolts broke out in the Doab and other areas. Imperial forces suppressed some uprisings but could not prevent others from spreading.

Military campaigns further strained resources. Muhammad bin Tughluq planned an expedition to Khorasan in Central Asia that mobilised a large army and spent substantial treasury funds before being cancelled. The Qarachil campaign in the Himalayan foothills (1337–1338) ended with heavy losses from terrain, disease, and local resistance. By the time of his death in 1351, during a campaign against rebels in Gujarat, more than two dozen provincial revolts had occurred. Bengal had already become independent under governors such as Shamsuddin Ilyas Shah around 1342. In the far south, the Madurai Sultanate was established in 1335 by Jalaluddin Ahsan Khan. In the Deccan, the Rebellion of Ismail Mukh in 1346–1347 led to the foundation of the Bahmani Sultanate in 1347 under Ala-ud-Din Bahman Shah.

After Firuz Shah's death in 1388, the Tughluq dynasty entered a phase of rapid succession and internal conflict. Between 1388 and 1413, several weak sultans held the throne amid factional struggles among nobles. By the 1390s, effective authority had contracted to the immediate vicinity of Delhi. In 1398, Timur invaded northern India, citing invitations from disaffected nobles amid the ongoing civil war between Nasir-ud-Din Mahmud Shah Tughluq and Nasir-ud-Din Nusrat Shah Tughluq. Timur's forces defeated the Delhi army outside the city, entered Delhi, and conducted a sack lasting several days that involved large-scale killing and seizure of valuables, including gold, silver, jewels, and elephants. Timur left Delhi after about two weeks and returned to Central Asia without establishing permanent rule. The Tughluq dynasty ended soon afterwards. It was followed by the Sayyid dynasty (1414–1451) and then the Lodi dynasty (1451–1526), both of which controlled progressively smaller territories.

The major regional sultanates that emerged during the decline and fragmentation of the Delhi Sultanate are commonly identified in historical accounts. Each developed through the assertion of independence by provincial governors, local dynasties, or rebellious leaders, often exploiting the weakening central authority after the mid-14th century.

The Kashmir Sultanate was established around 1320 by a Buddhist prince, Rinchan Shah and again in 1339 when Shah Mir, a Muslim adventurer and councillor, overthrew the Hindu Lohara dynasty that had ruled the region for centuries. Shah Mir assumed the title Sultan Shams-ud-Din and founded the Shah Mir dynasty. The sultanate maintained independence from Delhi throughout its existence, benefiting from Kashmir's geographical isolation in the Himalayas.

Under Sultan Zain-ul-Abidin (r. 1420–1470), often regarded as the most prominent ruler, the kingdom experienced significant administrative reforms, including improvements in irrigation, coinage, and taxation systems. Zain-ul-Abidin promoted religious tolerance, patronized Sanskrit scholars alongside Persian literature, and encouraged industries such as shawl weaving and paper-making. The sultanate continued under his successors until it was annexed by the Mughal Empire under Akbar in 1586 after a series of campaigns.

The Madurai Sultanate was founded in 1335 by Jalaluddin Ahsan Khan, a governor appointed by Muhammad bin Tughluq, who rebelled and declared independence in the Tamil region of the far south. Ahsan Khan, originally from Kaithal in northern India and identified as a Sayyid, established his capital at Madurai and extended control over parts of the former Pandya territories. The sultanate represented one of the earliest southern breakaways from Delhi.

The sultanate remained in existence for about four decades, facing constant pressure from neighbouring Hindu powers, particularly the rising Vijayanagara Empire. Successive rulers, including descendants of Ahsan Khan, maintained Muslim rule but struggled with internal instability and external threats. In 1377, the sultanate was overthrown by forces of the Vijayanagara Empire under Kumara Kampana, leading to the re-establishment of Hindu authority in the region.

The Bahmani Sultanate, often referred to as the Deccan Sultanate in its early phase, was founded in 1347 by Ala-ud-Din Bahman Shah (also known as Hasan Gangu or Zafar Khan), following the Rebellion of Ismail Mukh against Delhi's authority in the Deccan. The rebellion stemmed from grievances among local amirs (Amiran-i-Sada) appointed by Muhammad bin Tughluq. Bahman Shah established his capital initially at Gulbarga (later shifted to Bidar) and claimed descent from the legendary Bahman of Persian tradition.

The sultanate expanded through military campaigns against neighboring Hindu kingdoms, most notably engaging in prolonged wars with the Vijayanagara Empire over control of the Raichur Doab and other fertile areas. It promoted Persian culture, Shia influences in later periods, and architectural patronage. Internal factionalism among Afghan, Turkic, and Deccani nobles led to its division into five successor states (the Deccan Sultanates) by the late 15th century, including Ahmadnagar, Bijapur, Golconda, Berar, and Bidar.

The Sindh Sultanate came under the rule of the Samma dynasty from around 1351, when Jam Unar (Unar bin Babinah) defeated the last Soomra ruler and declared independence from the Delhi Sultanate. The Sammas, a Sindhi Muslim tribe claiming descent from Jamshid, established their capital at Thatta (Samanagar) and controlled the lower Indus valley. Early relations with Delhi involved periods of nominal submission, particularly during Firuz Shah Tughluq's campaigns in the 1360s, but full independence was achieved as central authority weakened.

The dynasty produced notable rulers who fostered trade along the Arabian Sea coast and maintained diplomatic ties with neighbouring powers like Gujarat. The sultanate endured until the early 16th century, when it was overthrown by the Arghun dynasty around 1520–1524, marking the end of Samma rule in the region.

The Bengal Sultanate emerged around 1338–1352 when local governors, beginning with Fakhruddin Mubarak Shah, Alauddin Ali Shah and Shamsuddin Ilyas Shah and solidified under the Ilyas Shahi dynasty from 1352, broke away from Delhi during Muhammad bin Tughluq's reign. Bengal had seen earlier revolts, but independence became permanent amid the chaos following Timur's invasion. The sultanate, with capitals at Gaur and later Pandua and Sonargaon, became one of the wealthiest due to its fertile delta, textile production, and maritime trade.

Under rulers like Ilyas Shah and the later Hussain Shahi dynasty, Bengal expanded territorially and patronized a blend of Persian, Arabic, and Bengali culture. It resisted Delhi's attempts at reconquest and maintained autonomy until Akbar's forces conquered it in 1576, incorporating it into the Mughal Empire.

The Khandesh Sultanate was established in 1382 by Malik Raja Faruqi (also known as Malik Ahmad or Raja Ahmad), who claimed descent from Caliph Umar and had served as a governor under Firuz Shah Tughluq. Granted a jagir in the Tapti Valley region, he declared independence after Firuz Shah's death and subdued local Rajput chieftains. The Faruqi dynasty ruled from capitals like Burhanpur and Asirgarh, positioning Khandesh as a buffer between larger powers such as Gujarat, Malwa, and Deccan states.

The sultanate relied on agriculture, trade routes, and textile production for prosperity. It navigated alliances and conflicts with neighbours until Akbar annexed it in 1601 after a siege of Asirgarh.

The Jaunpur Sultanate was founded in 1394 by Malik Sarwar, a wazir under the later Tughluqs who received the title Sultan-us-Sharq and established the Sharqi dynasty. Taking advantage of the post-Timur power vacuum, Sarwar and his successors expanded influence across the eastern Gangetic plain, often rivalling the Delhi Sultanate itself. The capital at Jaunpur became a centre of learning, earning the epithet "Shiraz of the East."

Rulers like Ibrahim Shah Sharqi promoted scholarship, architecture, and the arts. The sultanate was reabsorbed into the Lodi Sultanate of Delhi in 1479 after military campaigns by Bahlul Lodi.

The Gujarat Sultanate achieved full independence around 1394 under Zafar Khan (Muzaffar Shah I), who had been appointed governor by Firuz Shah Tughluq and declared sovereignty after Timur's invasion disrupted Delhi's control. His son Ahmad Shah I founded Ahmedabad as the capital in 1411. The Muzaffarid dynasty transformed Gujarat into a major maritime trading power with links to the Middle East, Africa, and Southeast Asia.

Rulers such as Mahmud Begada expanded territories and constructed notable mosques and forts. The sultanate fell to Akbar in 1573 following a Mughal siege of Ahmedabad.

The Malwa Sultanate was established around 1392–1401 by Dilawar Khan Ghuri, a governor who declared independence and shifted the capital to Mandu. After his death, his son Hoshang Shah and later the Khalji dynasty of Malwa (from Mahmud Khalji) ruled the region. Malwa served as a strategic buffer state, frequently contested by Gujarat, and Delhi.

The sultanate was known for its military campaigns and architectural patronage at Mandu. It was briefly occupied by Gujarat in the 1530s before Akbar annexed it in 1562.

The Multan Sultanate came under the Langah dynasty around 1445, when Budhan Khan (Mahmud Shah Langah) asserted control after the decline of earlier Tughluq influence in Punjab. The Langahs, possibly of Jat origin, ruled from Multan and extended authority over parts of southern Punjab and adjacent areas.

The sultanate maintained autonomy through the late 15th and early 16th centuries but was annexed by the Arghuns around 1527–1530, with some residual autonomy until full incorporation.

Several smaller or peripheral Muslim-ruled polities also emerged or asserted autonomy during this period:

• Mewat (Khanzadas of Mewat, c. 1372–1527): Centred in the Mewat region south of Delhi, this kingdom was ruled by Muslim Rajputs (Khanzadas) who gained de facto independence after 1427. Hasan Khan Mewati, a prominent ruler, allied with Rana Sanga against Babur at the Battle of Khanwa in 1527, after which Mewat lost autonomy to the Mughals.
• Baltiyul (Maqpon dynasty of Baltistan, prominent in 14th–16th centuries): Based in Skardu, this Shia Muslim dynasty ruled Baltistan under the Maqpon rulers. Ali Sher Khan Anchan (r. c. 1595–1633) expanded influence into Ladakh, Chitral, and Gilgit, maintaining practical independence from larger powers.
• Makran (various local rulers, 14th–16th centuries): The coastal region of Balochistan featured semi-independent Muslim chiefs and local sultans, functioning as a frontier zone with loose ties to neighboring entities. It saw rule by tribes such as the Ma'danid, Buledi and Gichki, with limited centralized authority until later incorporations.
• Deccan Sultanates (successors to the Bahmani Sultanate, c. 1490–1687): After the Bahmani fragmentation, five states emerged: Ahmadnagar (Nizam Shahi), Bijapur (Adil Shahi), Golconda (Qutb Shahi), Berar (Imad Shahi), and Bidar (Barid Shahi). These Shia-influenced kingdoms dominated the Deccan plateau until most were conquered by Aurangzeb in the late 17th century.
• Khokhar chieftaincy (under Shaikha and Jasrat Khokhar, c. 1390s–1442): A tribal-led autonomous polity of the Khokhars in northern Punjab centred around Sialkot, which resisted Timur and the Sayyid sultans through repeated campaigns, exercising de facto independence over much of Punjab before reconciliation with the Lodis.

The decline of the regional sultanates occurred progressively from the early 16th century onward, driven by internal weaknesses, mutual rivalries, and the expansion of the Mughal Empire. Most of the major sultanates that had emerged in the 14th and 15th centuries lost their independence through military conquest, diplomatic submission, or gradual absorption, with the process largely completed by the end of the 16th century for northern and western states and extending into the 17th century for the Deccan.

The First Battle of Panipat in 1526 marked the beginning of Mughal ascendancy in northern India. Babur defeated Ibrahim Lodi, ending the Lodi dynasty of Delhi and establishing Mughal rule over the core territories of the former Delhi Sultanate. This victory created a new imperial power capable of projecting force beyond the immediate environs of Delhi. Babur's successor Humayun faced setbacks, including temporary loss of territory to Sher Shah Suri (who briefly established the Sur Empire from 1540 to 1555), but Mughal control was restored under Akbar from 1556.

Akbar's reign (1556–1605) saw systematic campaigns against the remaining regional sultanates. Gujarat was conquered in 1573 after Akbar's forces besieged and captured Ahmedabad and defeated Muzaffar Shah III, ending Muzaffarid rule. Bengal followed in 1576 when Mughal armies defeated the last independent sultan, Daud Khan Karrani, incorporating the prosperous eastern sultanate into the empire. Malwa under Baz Bahadur had already fallen under Mughal control in 1562 after earlier contested periods involving Gujarat. Khandesh was annexed in 1601 from Bahadur Khan following the siege of Asirgarh by Akbar. Jaunpur had been absorbed earlier by the Lodis in 1479 from Husain Shah Sharqi and thus came under Mughal authority with the fall of Delhi. Sindh under Jam Feroz II and Multan under the child sultan Mahmud Langah were subdued by the Arghun dynasty in 1524 and 1527. While Multan was gifted away to the Mughals, Sindh remained firmly in the control of the Arghuns and later the Tarkhans. It was annexed in 1591 by Akbar from Mirza Jani Beg.

Kashmir maintained independence longer due to its mountainous terrain but was annexed in 1586 after Mughal campaigns led by Bhagwant Das and others forced the submission of the last Chak rulers, Yousuf Shah and his son Yakub Shah. Madurai, one of the earliest southern breakaways, ended much earlier in 1377 when Vijayanagara forces under prince Kumara Kampana defeated the last sultan, Ala-ud-Din Sikandar Shah and overthrew Muslim rule, restoring Hindu authority in the Tamil region. This represented one of the few instances of Hindu reconquest among the regional sultanates rather than Mughal absorption.

The Deccan Sultanates, successors to the Bahmani Sultanate, resisted Mughal expansion for a longer period. Ahmadnagar, Bijapur, Golconda, Berar, and Bidar faced repeated Mughal incursions from the time of Akbar onward. Berar was the first to fall, annexed by Ahmadnagar in 1574 and later coming under Mughal influence. Ahmadnagar was largely subdued by 1636 under Shah Jahan, though resistance continued intermittently. Bijapur and Golconda held out until Aurangzeb's campaigns in the 1680s, with both capitals falling in 1686 (Bijapur) and 1687 (Golconda), marking the effective end of independent Deccan sultanates.

Peripheral polities followed similar trajectories. The Mewat Khanzadas lost autonomy after Hasan Khan Mewati's defeat at the Battle of Khanwa in 1527 alongside Rana Sanga. The Khokhar chieftaincy under Jasrat Khokhar had already reconciled with the Lodis by the 1440s and was absorbed into the Mughal Punjab administration. Makran and Baltiyul (Maqpon dynasty) retained greater de facto autonomy due to their remote locations but gradually came under nominal Mughal suzerainty or local arrangements during the 16th and 17th centuries.

By the late 17th century, the Mughal Empire had incorporated the territories of nearly all the major regional sultanates, though resistance in the Deccan and frontier areas persisted. The decline reflected a combination of Mughal military superiority, administrative centralization under Akbar, and the exhaustion of many sultanates from prolonged internal conflicts and external pressures.

The period of the regional sultanates profoundly shaped the political landscape, economy, society, religion, and culture of the Indian subcontinent from the mid-14th to the late 17th century. By fragmenting the once-centralized Delhi Sultanate into multiple autonomous polities, the era created a long interval of regional autonomy that delayed large-scale unification until the Mughal conquests. This political decentralization allowed local rulers to adapt governance to regional conditions, but it also generated persistent interstate warfare that influenced demographic patterns, trade routes, and resource allocation.

Economically, the sultanates contributed to localized growth in agriculture, manufacturing, and commerce. In Bengal, the fertile delta supported intensive rice cultivation and a thriving textile industry (muslin and silk), with ports such as Satgaon and Chittagong facilitating trade with Southeast Asia and the Middle East. Gujarat emerged as a leading maritime hub under the Muzaffarids, exporting cotton textiles, indigo, and spices from ports including Cambay, Surat, and Broach; the sultanate's shipbuilding and customs revenues made it one of the wealthiest states of the time.

The Bahmani and successor Deccan sultanates developed diamond mining in Golconda and Bidar, while Khandesh benefited from transit trade along the Tapti valley route. Irrigation projects, such as the canals constructed in Gujarat and the improvements under Zain-ul-Abidin in Kashmir (including the restoration of the old Martand canal system), increased agricultural productivity in several regions. However, repeated conflicts, such as the Bahmani–Vijayanagara wars over the Raichur Doab (1360s–1520s) and the Jaunpur–Delhi rivalries, disrupted rural economies, caused population displacement, and diverted resources to military expenditure.

The sultanates fostered syncretic practices and elite intermingling. Persian served as the administrative and literary language, but regional vernaculars flourished: Bengali literature advanced under the patronage of the Hussain Shahi court (e.g., works by poets such as Maladhar Basu), Dakhni Urdu emerged in the Deccan as a literary medium, and Gujarati received support in Ahmedabad. Military alliances crossed religious lines, as seen in Hasan Khan Mewati's cooperation with Rana Sanga of Mewar against Babur in 1527 and the employment of Hindu soldiers in Deccan and Bengal armies.

The existence of multiple competing states created a balance of power that checked any single entity's dominance until the Mughal rise. The fragmentation strengthened certain Hindu kingdoms like the Rajput and Gondwana kingdoms and notably Vijayanagara, which ended the Madurai Sultanate in 1377 and contained Bahmani expansion for over a century. The regional sultanates transmitted administrative Iqta/Jagir systems, revenue assessment techniques) and military organization to the Mughals, who built a more centralized empire on these foundations while incorporating elements of regional diversity. The era thus represented a transitional phase that both fragmented and enriched the subcontinent's medieval history.

Religion was central to the identity and governance of the regional sultanates. Most followed Sunni Islam (Hanafi school), while Shia influences became prominent in the later Bahmani Sultanate and Deccan successor states such as Golconda and Bijapur. The sultanates advanced the spread of Islam in Bengal, the Deccan, Gujarat, Malwa, and Kashmir, largely through Sufi orders (Chishti, Suhrawardi, Qadiri) whose khanqahs and shrines attracted diverse followers including both Muslim and Hindu devotees and blended Islamic devotion with local traditions.

Religious policies differed across rulers and regions. Many enforced the Jizya tax on non-Muslims and patronized orthodox ulema and madrasas. Temple destruction occurred in specific contexts: Hoshang Shah and Mahmud Khalji in Malwa razed temples at Dhar, Mandu, and near the Kalka site for mosque and palace construction; early Muzaffarid rulers in Gujarat destroyed temples in Cambay during consolidation; the Madurai Sultanate desecrated certain Shaiva and Vaishnava temples in Tamil areas; Bahmani raids under Mohammed Shah I targeted temples in Vijayanagara territory; and Ibrahim Shah Sharqi in Jaunpur demolished some shrines during expansion. These acts were usually tied to military success or the reuse of materials for Islamic buildings. Ibn Batuta describes the Sultan of Madurai Ghiyasuddin Dhamgani's actions as:

the Hindu prisoners were divided into four sections and taken to each of the four gates of the great catcar. There, on the stakes they had carried, the prisoners were impaled. Afterwards their wives were killed and tied by their hair to these pales. Little children were massacred on the bosoms of their mothers and their corpses left there. Then, the camp was razed, and they started cutting down the trees of another forest. In the same manner did they treat their later Hindu prisoners. This is shameful conduct such as I have not known any other sovereign guilty of. It is for this that God hastened the death of Ghiyasuddin.

One day whilst the Qazi and I were having our food with (Ghiyasuddin), the Qazi to his right and I to his left, an infidel was brought before him accompanied by his wife and son aged seven years. The Sultan made a sign with his hand to the executioners to cut off the head of this man; then he said to them in Arabic: 'and the son and the wife.' They cut off their heads and I turned my eyes away. When I looked again, I saw their heads lying on the ground.

I was another time with the Sultan Ghiyasuddin when a Hindu was brought into his presence. He uttered words I did not understand, and immediately several of his followers drew their daggers. I rose hurriedly, and he said to me; 'Where are you going' ? I replied: 'I am going to say my afternoon (4 o'clock) prayers.' He understood my reason, smiled, and ordered the hands and feet of the idolater to be cut off. On my return I found the unfortunate swimming in his blood.^[12]

Conversely, notable tolerance existed. Zain-ul-Abidin in Kashmir abolished jizya, restored temples at Martand and Avantipur, banned cow slaughter, appointed Hindu officials, and supported Sanskrit-to-Persian translations. The Hussain Shahi sultans of Bengal employed Hindu revenue officers, granted land to Brahmins, and allowed temple construction. Deccan courts integrated Hindu nayakas into high positions and patronized Hindu festivals. Pragmatic alliances with Hindu elites were common in Gujarat and Khandesh. Sufi saints like Shah Jalal (Bengal), Gesu Daraz (Deccan), and Jahaniyan Jahangasht (Multan) fostered interfaith interaction through devotion, music, and charity.

The legal framework blended Islamic sharia with Indian customary and administrative practices. Sharia governed Muslim personal law (marriage, inheritance, divorce) under qazis in major towns, with Hanafi jurisprudence dominant (Shia elements in later Deccan states). Criminal law mixed hudud and ta'zir penalties with local customs. Iqta and jagir systems for revenue and military service were often made hereditary, following Tughluq precedents.

Non-Muslims retained customary laws for community matters, with panchayats handling civil disputes in Bengal, Gujarat, and Kashmir. Jizya was collected in most sultanates (abolished in Kashmir under Zain-ul-Abidin). Land revenue used measurement (Jerib) and crop-sharing or cash assessments, with reforms in Kashmir and Bengal to encourage cultivation. Criminal justice combined Islamic penalties (rarely full hudud) with fines, imprisonment, and corporal punishment from local usage.

Literature flourished under court sponsorship. In Bengal, the Hussain Shahi dynasty (1494–1538) patronized early Bengali literature, including devotional works by poets such as Maladhar Basu (Sri Krishna Vijaya) and Chandidas, blending Vaishnava themes with Islamic mysticism. In the Deccan, Dakhni Urdu emerged as a literary medium, with poets composing in a mix of Persian, Arabic, Turkic, and local languages; Muhammad Quli Qutb Shah of Golconda (r. 1580–1611) wrote notable ghazals in Dakhni. Jaunpur earned the title "Shiraz of the East" for its scholarly environment under Ibrahim Shah Sharqi (r. 1401–1440), who supported Persian poetry, theology, and history. Kashmir under Zain-ul-Abidin (r. 1420–1470) became a hub for translation projects, rendering Sanskrit texts (including the Mahabharata and Rajatarangini) into Persian, alongside original works in Persian and Kashmiri. Gujarat and Malwa courts produced historical chronicles and poetry in Persian, while Sufi literature in regional languages spread devotional themes across communities.

Music and performing arts advanced through royal patronage and Sufi influence. Courts employed musicians skilled in Persian maqam systems and Indian ragas, leading to early forms of qawwali and khyal. Sufi gatherings featured sama (musical sessions) that integrated local folk melodies. Dance forms, including early precursors to Kathak, appeared in some Deccan and northern courts, often performed during festivals.

Architecture represents one of the most enduring legacies of the regional sultanates. Buildings combined arched gateways, domes, minarets, and geometric patterns from Islamic traditions with Indian elements such as chhatris, jali screens, bracketed pillars, and lotus motifs.

A combination of contemporary and near-contemporary Persian chronicles, regional court histories, Sanskrit and vernacular texts, inscriptions, numismatic evidence, and accounts by travellers, supplemented by later Mughal and colonial-era interpretations provide detailed but often biased narratives shaped by the perspectives of court chroniclers, religious affiliations, and political agendas.

Primary sources from the period include Persian tarikhs produced under sultanate patronage. For the Bahmani and Deccan sultanates, the most comprehensive account is Muhammad Qasim Firishta’s Tarikh-i-Firishta (also known as Gulshan-i-Ibrahimi, completed c. 1610–1620), which draws on earlier lost works and covers the Bahmani dynasty, its successors, and many northern sultanates. For Bengal, contemporary accounts include the Tarikh-i-Firuz Shahi by Ziauddin Barani (for the Tughluq context leading to Bengal’s independence) and numerous inscriptions from the Ilyas Shahi and Hussain Shahi periods; the later Riyaz-us-Salatin (1788) compiles these materials. Jaunpur’s Sharqi dynasty is documented in the Tarikh-i-Mubarak Shahi by Yahya bin Ahmad Sirhindi (c. 1434). Gujarat’s history is preserved in the Mirat-i-Sikandari by Sikandar bin Muhammad (c. 1611), while Malwa’s Khalji rulers appear in the Ma’asir-i-Mahmud Shahi and are incorporated into Nizamuddin Ahmad’s Tabaqat-i-Akbari (c. 1593).

For Kashmir, unusually rich contemporary sources survive. Jonaraja's Sanskrit continuation of Kalhana’s Rajatarangini (mid-15th century) provides a near-contemporary account up to the reign of Zain-ul-Abidin, while his successor Shrivara extended the chronicle into the later Shah Mir period. These are supplemented by the Persian Baharistan-i-Shahi (anonymous, c. 1590s), a dedicated history of the sultanate written shortly after its Mughal annexation, along with later Persian translations of the Sanskrit texts.

Travelers’ accounts offer external perspectives: Ibn Battuta (who visited during Muhammad bin Tughluq's reign and described early rebellions and the Madurai governorate), Abdur Razzaq (Bahmani court, 1443), Niccolò de’ Conti (1420s), and Afanasy Nikitin (1468–1474). Mughal historians such as Abu’l-Fazl (Akbarnama and Ain-i-Akbari, c. 1590s) and Nizamuddin Ahmad portrayed the sultanates as fragmented to justify imperial expansion, while Badauni’s Muntakhab-ut-Tawarikh adds sectarian commentary.

Colonial-era translations in Elliot and Dowson’s The History of India, as Told by Its Own Historians (1867–1877) made many Persian texts accessible but framed them within a narrative of Muslim rule versus Hindu revival. Modern scholarship by Richard Eaton, Peter Jackson, Carl Ernst, Muzaffar Alam, and Sanjay Subrahmanyam uses these sources alongside epigraphy, archaeology, and vernacular materials to present a more balanced view of state formation, religious pluralism, and cultural exchange.

Ilyas Shahi dynasty (1342–1414)

In 2009 a coin of a ruler named Nasiruddin Ibrahim Shah was found in Bangladesh, which was struck in 818 AH (around 1416 CE). It is possible he was a claimant to the throne.
