Why this matters now

Delhi Sultanate is foundational GS-1 Medieval History. Three reasons. First, the Sultanate transformed Indian polity, religion, language, architecture, and administration permanently. Second, the Bhakti-Sufi movements created the shared spiritual vocabulary of medieval and modern India. Third, Alauddin's market regulation and Muhammad bin Tughlaq's currency experiment are studied in modern economic history as pioneering attempts at state economic management.

Origin and founding

The Sultanate emerged from the Ghorid invasions:

  • Battle of Tarain I (1191) — Prithviraj Chauhan defeated Muhammad Ghori;
  • Battle of Tarain II (1192) — Ghori defeated Prithviraj — decisive moment;
  • 1206 — Ghori died; his slave-general Qutbuddin Aibak declared independence from Lahore;
  • Capital shifted to Delhi under Iltutmish.

Slave / Mamluk Dynasty (1206-1290)

  • Qutbuddin Aibak (1206-10) — Founder; Turkic slave-general; began Qutb Minar; died in polo accident at Lahore;
  • Iltutmish (1211-36) — Real founder of Sultanate state; capital to Delhi; Caliph of Baghdad investiture; silver tanka and copper jital; completed Qutb Minar;
  • Razia Sultana (1236-40) — Iltutmish's daughter; first woman Muslim ruler of Delhi; rejected by Turkan-i-Chahalgani (Forty Nobles); killed 1240;
  • Ghiyasuddin Balban (1266-87) — Slave-Sultan; broke power of Forty Nobles; introduced Persian court rituals (Sijdah, Paibos); "Sultan is God's Shadow".

Khilji Dynasty (1290-1320)

  • Jalaluddin Khilji — founder; relatively mild;
  • Alauddin Khilji (1296-1316) — most powerful Sultan; details below.

Alauddin Khilji's market regulation

Alauddin built the first medieval Indian planned economy.

Three Delhi markets

  • Mandi (grain);
  • Sarai-i-Adl (cloth, sugar, oil, ghee);
  • Markets for slaves, cattle, horses.

Mechanisms

  • Fixed prices on essential goods;
  • Diwan-i-Riyasat appointed to enforce; Shahna-i-Mandi market superintendent;
  • Punishments for cheating — flesh equivalent to short-weight cut from cheating merchant;
  • Royal grain reserves; rationing during shortages;
  • Bania traders registered; gold/silver smiths regulated.

Conquests and military

  • Conquered Gujarat, Rajasthan, Deccan;
  • Malik Kafur expeditions to Devagiri, Warangal, Madurai (1310);
  • Permanent standing army of 4.75 lakh well-paid soldiers;
  • Branding of horses (Dagh); descriptive rolls (Chehra);
  • Successfully resisted Mongol invasions.

Prices stable for ~20 years. After Alauddin's death (1316), controls collapsed.

Tughlaq Dynasty (1320-1414)

  • Ghiyasuddin Tughlaq — founder;
  • Muhammad bin Tughlaq (1325-51) — details below;
  • Firoz Shah Tughlaq (1351-88) — welfare-oriented; irrigation canals (West Yamuna Canal, Hisar Canal); maktabs (schools), dar-ul-shafa (hospitals); jizya on Brahmins; reduced revenue assessment.

Muhammad bin Tughlaq — the "Wise Fool"

Brilliant but disastrous experiments.

  1. Tax increase in Doab (1325-26) — coincided with famine; widespread distress; later reduced;
  2. Capital transfer to Daulatabad (~1327) — forced entire Delhi population to migrate ~700 miles south; capital reverted to Delhi 1335;
  3. Token currency (~1329-32) — copper tokens at par with silver tankas; counterfeiting rampant; merchants accumulated silver, used copper for taxes; Sultan forced to buy back coins at huge loss;
  4. Khurasan-Qarajal expeditions — Khurasan abandoned without launch; Qarajal Himalayan expedition saw only 10 of 10,000 soldiers return;
  5. Died of fever in 1351 during Taghi campaign at Thatta.

Hindu rebellions during his reign — Vijayanagara Empire (1336) and Bahmani Sultanate (1347) established. Sultanate began contracting.

Ibn Battuta visited his court and described him.

Sayyid (1414-51) and Lodi (1451-1526) Dynasties

  • Sayyid dynasty — Khizr Khan; weak rulers; sultanate under Timurid pressure;
  • Lodi dynasty — Bahlol, Sikandar, Ibrahim Lodi;
  • 21 April 1526 — First Battle of Panipat — Babur defeated Ibrahim Lodi using artillery and field engineering tactics. End of the Delhi Sultanate. Mughal Empire begins.

Administration and the iqta system

  • Centralised Muslim monarchy;
  • Sultan absolute authority; advised by Wazir (PM), Diwan-i-Arz (army), Diwan-i-Insha (correspondence), Diwan-i-Rasalat (foreign affairs);
  • Iqta system — revenue assignments to nobles in lieu of cash salary; muqti/iqtadar collected revenue, maintained troops; foundation of medieval Indian administration;
  • Persian as court language;
  • Iqta system reformed by Alauddin (direct revenue collection in core areas);
  • Indo-Islamic architecture — Qutb Minar (Delhi), Alai Darwaza, Tughlaqabad, Lodi Gardens — Persian-Hindu architectural synthesis.

Bhakti movement — devotional revolution

Spreading north during the Sultanate, Bhakti rewrote Indian religious life.

Saguna Bhakti (with attributes)

  • Ramanuja (11-12 c); Madhva; Vallabha; Ramananda;
  • Worship of Vishnu, Shiva, Devi.

Nirguna Bhakti (formless God)

  • Kabir (~1440-1518) — synthesised Hindu and Muslim devotion;
  • Guru Nanak (1469-1539) — founded Sikhism;
  • Ravidas; Dadu.

Women saints

  • Mirabai (~1498-1547) — Krishna devotee;

Regional traditions

  • Maharashtra — Jnaneshwar (13c), Namdev, Tukaram;
  • Bengal — Chaitanya (16c);
  • Karnataka — Basava (12c, Veerashaivism);
  • Tamil — Alvars and Nayanars (earlier).

Used vernacular languages (Hindi, Marathi, Punjabi, Bengali, Tamil, Kannada). Critiques of caste, ritualism, idol worship (Nirguna), orthodox Brahmanism.

Sufi movement — Islamic mysticism

Four major silsilas (orders)

  • Chishti — most popular; Khwaja Moinuddin Chishti at Ajmer ("Gharib Nawaz"); Nizamuddin Auliya at Delhi;
  • Suhrawardi — Multan; Bahauddin Zakariya;
  • Qadiri;
  • Naqshbandi — later; opposed syncretism.

Key features

  • Love of God; mystical experience; music (qawwali); meditation (zikr);
  • Khanqah (hospice) as centre;
  • Welcomed all castes/religions;
  • Amir Khusro (1253-1325) — disciple of Nizamuddin Auliya; poet; introduced qawwali; "Tuti-i-Hind" (parrot of India).

Bhakti-Sufi interaction

Bhakti and Sufi influenced each other. Kabir synthesised both. Nanak founded Sikhism drawing from both. Common themes — divine love, devotion, equality before God, rejection of caste/ritualism. Cultural syncretism — Hindustani music, language, cuisine.

Vijayanagara and Bahmani — South India during Sultanate

  • Vijayanagara Empire (1336-1646) — founded by Harihara and Bukka (Sangama dynasty); peak under Krishnadevaraya (1509-29); Hampi capital; defeated at Battle of Talikota 1565;
  • Bahmani Sultanate (1347-1527) — founded in Deccan after Tughlaq revolts; later split into five Deccani sultanates (Bijapur, Golconda, Ahmadnagar, Berar, Bidar);
  • Long Vijayanagara-Bahmani rivalry shaped Deccan politics.
"The Delhi Sultanate was not just a political phase but a cultural foundry — Indian Islam, Hindustani language, Indo-Islamic architecture, the Bhakti-Sufi spiritual synthesis, the iqta administrative model — all forged in these 320 years." — paraphrasing Satish Chandra's Medieval India
