Delhi Sultanate Governance and Technology

Why the Delhi Sultanate matters for CDS

The Sultanate period is the bridge between ancient and Mughal India, and the UPSC CDS paper regularly draws one or two questions from it. Questions are usually factual — who introduced the iqta, which ruler shifted the capital, who started market control — so accurate recall beats vague reading. The chapter also overlaps with art and culture, economy and even general-knowledge sections, which makes the return on study time unusually high.

The Sultanate arose after Muhammad of Ghor's victory over Prithviraj Chauhan at the Second Battle of Tarain (1192). His Turkish slave-generals carved out a kingdom in north India, and from this base a centralised Indo-Islamic state took shape. Across roughly 320 years, five dynasties ruled from Delhi:

• Slave / Mamluk dynasty (1206–1290) — Aibak, Iltutmish, Razia, Balban.
• Khalji dynasty (1290–1320) — Jalaluddin, Alauddin.
• Tughlaq dynasty (1320–1414) — Ghiyasuddin, Muhammad bin Tughlaq, Firoz Shah.
• Sayyid dynasty (1414–1451).
• Lodi dynasty (1451–1526) — Bahlul, Sikandar, Ibrahim, ended at Panipat.

The Sultan and the ruling class

The Sultan was the head of state, commander-in-chief and chief justice rolled into one. In theory he was a deputy of the Caliph and often sought a mansur (letter of investiture) to add legitimacy. In practice his real strength rested on the army and the loyalty of the nobles.

The nobility was a mixed and quarrelsome group: Turks, Afghans, Persians and later Indian Muslims. Balban tried to tame them by exalting royal prestige; Alauddin Khalji crushed their independent power; the Lodis, being Afghans, treated nobles as near-equals, which weakened central authority. The constant tension between a Sultan who wanted absolute power and nobles who wanted a share of it is the recurring theme of Sultanate politics, and it explains why strong rulers like Balban and Alauddin built spy networks and standing armies.

Iltutmish deserves special note as the real consolidator of the Sultanate. He defeated rivals, secured the throne for his line, shifted the capital firmly to Delhi, obtained recognition from the Caliph of Baghdad, and nominated his able daughter Razia as successor — the first and only woman to rule from the Delhi throne.

Central government and key officers

The Sultanate ran on a small set of central departments, each headed by a senior officer. These titles are favourite one-word CDS answers.

• Wazir — prime minister, headed the finance department (diwan-i-wizarat).
• Ariz-i-mumalik — controller-general of the military (diwan-i-arz); recruited, paid and inspected troops.
• Diwan-i-insha — department of royal correspondence and farmans.
• Diwan-i-risalat — dealt with religious affairs, charity and stipends to the learned.
• Sadr-us-sudur — chief religious officer; Qazi-i-mumalik — chief judge (often the same person).
• Barid-i-mumalik — head of the intelligence and postal network.

The iqta system

The iqta was the backbone of provincial administration and army pay. An iqta was a tract of land whose revenue was assigned to a noble (the iqtadar or muqti) instead of a cash salary. In return he maintained troops and remitted the surplus to the centre.

Iltutmish is credited with systematising the iqta in India. Originally transferable and non-hereditary, it kept nobles dependent on the Sultan. Over time, especially under Firoz Shah Tughlaq, iqtas tended to become hereditary, weakening royal control.

The empire was divided into provinces (iqtas), then shiqs, parganas and villages. The village remained the basic unit, run by the headman (muqaddam) and accountant (patwari). The strength of the iqta system was that it let the Sultan pay and maintain a large army without a developed cash economy; its weakness was that powerful iqtadars could grow into independent warlords whenever the centre weakened.

Land revenue and taxation

Land revenue (kharaj) was the chief source of income. Theoretically Muslim jurists recognised four taxes: kharaj (land tax), khams (one-fifth of war booty and mines), jizya (tax on non-Muslims) and zakat (charity tax on wealthy Muslims).

• Alauddin Khalji fixed land revenue at 50% of produce in the doab, measured land (masahat), and curbed the privileges of intermediaries (khuts, muqaddams, chaudharis).
• Ghiyasuddin Tughlaq moderated the demand and encouraged agriculture.
• Muhammad bin Tughlaq sharply raised the doab tax during a famine — a notorious failure that caused revolts.
• Firoz Shah Tughlaq abolished many vexatious cesses, dug canals and levied the haq-i-sharb (water/irrigation tax) of about 1/10th on canal-irrigated land.

Alauddin Khalji's market control

The most famous economic experiment of the Sultanate was Alauddin Khalji's market reform (price control). To maintain a huge standing army cheaply — needed against repeated Mongol invasions — he fixed low prices for almost all goods.

• Separate markets for grain (mandi), cloth and costly goods (Sarai Adl), and horses/cattle/slaves.
• A shahna-i-mandi (market superintendent) enforced rates; spies and the Sultan's own inspectors checked compliance.
• State granaries stored grain so that prices stayed stable even in famine.
• Traders were registered and merchants who under-weighed goods were punished severely.

Coins, currency and the token experiment

The Sultanate gave India a regular silver and copper coinage. Iltutmish introduced the silver tanka (about 175 grains) and the copper jital, setting the standard coinage of the period.

Muhammad bin Tughlaq attempted a bold experiment in token currency around 1329–30: he issued bronze/brass coins meant to circulate at the value of silver tankas. The idea anticipated modern fiat money, but the state could not stop widespread forgery; every household became a mint, and the experiment was withdrawn at great loss. He had to redeem the bronze coins for genuine silver, and heaps of forged tokens piled up outside the fort at Tughlaqabad.

Muhammad bin Tughlaq's experiments

No Sultan is more associated with bold, ill-fated schemes than Muhammad bin Tughlaq (1325–1351). Examiners love grouping his projects:

• Transfer of capital from Delhi to Daulatabad (Devagiri) in the Deccan — intended for central control but caused great hardship; he later moved back.
• Token currency — the bronze coin experiment described above.
• Taxation of the Doab — an ill-timed increase during famine that triggered revolts.
• Khurasan and Qarachil expeditions — ambitious campaigns that drained the treasury.

Technology introduced during the Sultanate

The Sultanate was a period of significant technological diffusion, as ideas from Central Asia and West Asia entered India. This is an increasingly common CDS theme.

Agriculture and water-lifting

The Persian wheel (saqiya / araghatta with gearing) spread widely, using a chain of pots and gear-wheels driven by animals to lift water for irrigation — raising productivity in north India.

Textiles

The spinning wheel (charkha) reached India in this era and greatly increased yarn output, boosting cotton-cloth production. The cotton carder's bow also improved cleaning of cotton. Sericulture and silk-weaving expanded, and Indian textiles became important items of trade with West and Central Asia.

Building and crafts

• The true arch and dome built on the principle of the keystone (e.g., Alai Darwaza) replaced the older corbelled style.
• Use of lime mortar as a strong cement allowed taller, lighter structures.
• Introduction or spread of paper aided administration and learning.

Architecture, towns and society

The new building technology produced a distinctive Indo-Islamic architecture. Qutbuddin Aibak began the Qutb Minar (completed by Iltutmish) and the Quwwat-ul-Islam mosque; Alauddin added the Alai Darwaza; Firoz Shah founded Firozabad and built canals and the Firoz Shah Kotla.

Urban growth, a money economy and the demand of the elite for fine goods stimulated crafts and trade. A new composite culture emerged — in language (early Hindavi/Urdu), music, dress and the Sufi and Bhakti movements that flourished alongside the state. The poet Amir Khusrau, attached to several Sultans, is remembered as a pioneer of this blended culture and is often called the "Parrot of India". Sufi saints of the Chishti order, such as Nizamuddin Auliya, drew followers of all faiths, while Bhakti saints spread devotion in regional tongues — together softening rigid social boundaries.

Worked example: dating and sequencing

CDS often asks you to match rulers with reforms or arrange events chronologically. Practise with a model question.

Anchoring each reform to its ruler's reign lets you sequence events even if exact years slip your memory.
