Position of the Sultan
The Delhi Sultanate was an absolute monarchy where the Sultan held ultimate executive, legislative, military, and judicial authority. There was no formal constitution, elected assembly, or permanent law code — authority derived from the sultan's will, bounded in theory by Islamic law (shariat) and advised by the ulema (religious scholars).
In practice, sultans differed enormously in how much they deferred to the ulema. Alauddin Khalji famously told his advisor that he governed by policy, not by the shariat; Firuz Shah Tughlaq was the opposite — deeply pious and deferential to religious opinion. The tension between royal power and Islamic law is a recurring theme of the Sultanate period.
Central Departments (Diwan)
The Sultanate's central administration was organised into five major departments, each headed by a senior officer:
| Department | Head | Function |
|---|---|---|
| Diwan-i-Wizarat | Wazir (Prime Minister) | Overall revenue administration; the most powerful minister; headed the whole financial machinery |
| Diwan-i-Ariz | Ariz-i-Mamalik | Military affairs: recruitment, payment, supplies; NOT the commander-in-chief (sultan commanded the army) |
| Diwan-i-Insha | Dabir-i-Khas | Royal correspondence, state letters, firmans (orders); the secretariat |
| Diwan-i-Risalat | Sadr-us-Sudur | Foreign affairs, religious endowments (waqf), appeals; the Sadr-us-Sudur also headed religious matters |
| Diwan-i-Qaza | Qazi-ul-Quzat | Chief justice; administered Islamic law; judicial appeals |
The Wazir and Diwan-i-Wizarat
The Wazir (Prime Minister) was the most important minister after the sultan. He headed the Diwan-i-Wizarat — the revenue department — and was involved in all major policy decisions. Under strong sultans (like Balban and Alauddin Khalji), the Wazir was a subordinate executive. Under weak sultans, the Wazir effectively ran the government.
The revenue department maintained the mustaufi (auditor-general) and mushrif (accountant-general) under it, along with a vast network of provincial revenue officers.
Ariz-i-Mamalik — A Common UPSC Trap
The Ariz-i-Mamalik headed the Diwan-i-Ariz (military department). His functions were:
- Recruitment of soldiers
- Payment of military salaries
- Maintaining descriptive rolls (chehra) and horse branding (dagh) records
- Procurement of military supplies and equipment
The most common UPSC trap: the Ariz-i-Mamalik was NOT the commander-in-chief of the army. He was an administrator — a recruiter and paymaster. The sultan himself commanded the army in battle, assisted by designated commanders. The Ariz-i-Mamalik never led troops into battle. This distinction appears repeatedly in UPSC questions.
Other Important Officers
| Officer / Department | Function |
|---|---|
| Sadr-us-Sudur | Head of religious affairs; supervised waqf (religious endowments); issued grants to scholars and mosques; also headed Diwan-i-Risalat |
| Qazi-ul-Quzat | Chief Justice; highest judicial authority under the sultan; administered shariat law |
| Barid-i-Mamalik | Chief of intelligence/espionage; ran the network of Barids (postal-intelligence agents) across the empire |
| Wakil-i-Dar | In charge of the royal household |
| Amir-i-Hajib | Chamberlain; controlled access to the sultan; maintained court protocol |
| Naib Sultan | Deputy sultan — regent when the sultan was absent; Balban held this post before becoming sultan |
| Kotwal | City police officer; maintained law and order in urban areas; registered foreigners, supervised weights and measures |
The Iqta System
The Iqta system was the fiscal backbone of the Delhi Sultanate. Systematised by Iltutmish, it involved assigning a territory's revenue to a soldier or officer in lieu of cash salary.
| Term | Meaning |
|---|---|
| Iqta | The revenue assignment itself (the territory) |
| Muqti / Wali / Iqtadar | The holder of the iqta; collected revenue from the assigned territory |
| Khwaja | Government accountant posted alongside the muqti; audited revenues; ensured surplus was sent to the sultan |
| Fawazil | Revenue surplus from an iqta that the muqti remitted to the central treasury |
Key features: Iqtas were theoretically non-hereditary and transferable at the sultan's will. The muqti had to maintain a specified number of cavalry from his iqta revenue. The system ensured a distributed military force across the empire without the state having to pay cash salaries centrally. However, over time iqtas tended to become de facto hereditary — a persistent problem sultans tried to correct.
Provincial Administration
| Level | Name | Head |
|---|---|---|
| Province | Iqta (large) / Wilayat | Muqti / Wali (governor) |
| District | Shiqq | Shiqdar |
| Pargana | Pargana | Amil (revenue) + Shiqdar (law and order) |
| Village | Gram / Deh | Muqaddam (headman) + Patwari (accountant) |
Below the provincial level, the Sultanate largely relied on existing local structures — Hindu zamindars and village headmen (muqaddams) who collected revenue and maintained order at the local level. Direct state penetration to the village was limited; the Sultanate was more an empire of tribute and revenue extraction than a modern bureaucratic state.
Revenue System
| Tax | Who paid it | Rate / Notes |
|---|---|---|
| Kharaj | All cultivators (land tax) | Standard rate: 1/3 of produce; Alauddin raised it to 1/2 (50%) |
| Jaziya | Non-Muslims (Hindus, Jains, Christians) | Poll tax; three categories (rich/middle/poor); Brahmins exempt until Firuz Shah; women, children, disabled exempt |
| Zakat | Muslims only | Islamic alms tax = 2.5% of wealth above nisab (minimum threshold); went to Islamic charitable causes |
| Kharaj (Ushr) | Muslim cultivators | Tithe — 1/10 of produce from rain-fed land; 1/20 from irrigated land |
| Ghari | Non-Muslims | House tax introduced by Alauddin Khalji |
| Charai | Non-Muslims | Cattle grazing tax introduced by Alauddin Khalji |
| Khams | Treasury | 1/5 of war booty went to the sultan; remainder divided among soldiers |
Jaziya = paid by non-Muslims; a poll tax in return for protection (dhimmi status). Zakat = paid by Muslims; an Islamic religious obligation (one of the five pillars of Islam); 2.5% of wealth. They are NOT the same tax, paid by different groups for entirely different reasons. UPSC frequently mixes these up in options.
Judicial System
The Delhi Sultanate judicial system had a dual structure:
- Qazi-ul-Quzat (Chief Justice) — applied Islamic law (shariat) to cases involving Muslims
- Sadr-us-Sudur — issued religious rulings and oversaw waqf (endowment) matters
- Local Qazis — at the district and town level
- Hindu customary law — the Sultanate generally did not interfere in civil matters among Hindus (property, inheritance, marriage); these were governed by local customs and panchayats
The Sultan himself was the ultimate court of appeal — in practice, he could overrule any judge. Balban and Muhammad bin Tughlaq were particularly known for personal judicial decisions, sometimes harsh to the extreme.

Frequently Asked Questions
What was the Iqta system?
A revenue assignment where territory's taxes were given to an officer (muqti) instead of cash salary. The muqti maintained soldiers from this revenue and remitted surplus (fawazil) to the sultan. A Khwaja (accountant) was posted alongside to audit revenues. Theoretically non-hereditary. Systematised by Iltutmish.
What were the five main Diwans of the Delhi Sultanate?
Diwan-i-Wizarat (revenue, headed by Wazir), Diwan-i-Ariz (military, headed by Ariz-i-Mamalik — NOT the commander-in-chief), Diwan-i-Insha (correspondence), Diwan-i-Risalat (foreign affairs/religion, headed by Sadr-us-Sudur), Diwan-i-Qaza (judiciary, headed by Qazi-ul-Quzat).
What is the difference between Jaziya and Zakat?
Jaziya = poll tax paid by non-Muslims (Hindus, Jains, Christians) for protection under an Islamic state. Zakat = Islamic religious tax paid by Muslims — 2.5% of wealth above minimum threshold, one of the five pillars of Islam. They are paid by different groups for different reasons.
