THE DELHI SULTANATE (1206 – 1526 AD)

Comprehensive Guide for UPSC (IAS/IPS), State PSCs, CDS, and SSC Aspirants

The establishment of the Delhi Sultanate in the 13th century marked the beginning of a new phase in Indian history. It introduced the Turko-Persian tradition, leading to a rich synthesis of culture, architecture, and administrative systems. For over 300 years, five major dynasties ruled from Delhi, each contributing uniquely to the development of the Indian sub-continent.

1. Chronological Timeline of the Sultanate

Dynasty	Timeframe	Character of Rule	Dominant Region
Mamluk (Slave)	1206 - 1290	Initial stabilization of Turkish rule.	North India
Khalji	1290 - 1320	Period of Imperialism and Market Reforms.	North and South India
Tughlaq	1320 - 1414	Geographic Expansion followed by Decline.	Almost Entire Sub-continent
Sayyid	1414 - 1451	Consolidation in a small territory.	Delhi & Punjab
Lodi	1451 - 1526	Era of Afghan Chieftains and final decay.	North India

2. Deep Dive: Mamluk Dynasty (1206–1290)

The Beginning: Qutb-ud-din Aibak

Aibak was the trusted lieutenant of Muhammad Ghori. Following Ghori’s assassination, Aibak broke away from Ghazanvi and became the first Independent Turkish Sultan of India. He ruled from Lahore and was famously called "Lakh Baksh" for his excessive generosity.

The Real Stabilizer: Shamsuddin Iltutmish

UPSC frequently tests candidates on Iltutmish because he made Delhi his capital. Key features of his rule include:

• Formation of Turkan-i-Chahalgani (Group of 40 trusted slave officers).
• Introduction of purely Arabic coinage: the Silver Tanka and Copper Jital.
• Organization of the Iqta System, assigning land revenue for military services.
• Completed the construction of Qutub Minar and received recognition from the Caliph.

3. The Khalji Revolution (1290–1320)

Imperial Ambitions of Alauddin Khalji

Alauddin’s reign represents the zenith of the Sultanate's central power. His administrative and military reforms were unprecedented:

Major Market Control Reforms

To maintain a large standing army with low salaries, he established Shahna-i-Mandi.

• Prices of all commodities (grains, horses, clothes) were fixed.
• Black-marketing was strictly punished.
• The Diwan-i-Mustakharaj department was created to recover unpaid revenue.
• Introduced Dagh (Branding of horses) and Chehra (Biographical descriptive rolls for soldiers) to prevent corruption.

4. Experimentation and Chaos: The Tughlaq Dynasty

The Great Dreamer: Muhammad bin Tughluq (MBT)

Considered a brilliant scholar yet a poor politician. His "Four Major Failed Projects" are often asked in UPSC Mains/Prelims:

1. Taxation in Doab: Raised taxes in the middle of a famine.
2. Capital Shift: Transfer from Delhi to Devagiri (Daulatabad).
3. Token Currency: Introduced Bronze/Copper coins par with Gold/Silver without govt. backing.
4. Qurachil/Khorasan Expeditions: Resulted in immense loss of human lives and funds.

Firoz Shah Tughluq: The Benevolent Ruler?

Known for his social reforms rather than military conquests.

• He built over 300 towns, including Firozabad, Jaunpur, and Hissar.
• Constructed major canals for irrigation.
• Created Diwan-i-Khairat (Charity Department) and Dar-ul-Shifa (Charitable Hospitals).
• Reintroduced Jizya as a separate tax for Brahmins.

5. Administrative Machinery of the Sultanate

Officer	Responsibility / Function
Wazir	Prime Minister; Looked after Finance.
Ariz-i-Mumalik	Head of Military Department (Recruitment and Equipment).
Dabir-i-Khas	In charge of Royal Secretariat/Correspondence.
Sadr-us-Sudur	Chief Justice and head of Religious Affairs.

6. Art and Architecture

The Sultanate era introduced the Indo-Islamic style, characterized by Arches, Domes, and Minarets.

• Lodi Style: Use of double domes and Octagonal tombs in Delhi (Lodi Gardens).
• Materials: Red sandstone, marble, and grey granite were heavily used.
