The five dynasties and the character of Sultanate rule

Detail

How the Sultanate began

• The NCERT chapter dates the making of the Delhi Sultanate from the defeat of Prithviraj Chauhan in 1192.
• After that defeat, Turkic commanders stayed on and ruled from Delhi instead of raiding and going home. This is the key change from the earlier Ghaznavid and Ghurid raids.
• Over the next three centuries, five dynasties held Delhi one after the other. All five were of Turkic-Afghan origin — that is, foreign in origin, not local Indian ruling houses.

The five dynasties in order

Order	Dynasty	Dates (external)	First ruler / key point
1	Mamluks ('Slave dynasty')	—	Founders of the Delhi Sultanate; Qutb-ud-din Aibak was the first [4]
2	Khiljis (Khaljis)	1290–1320 [4]	Founded when Jalal-ud-din Firuz Khalji seized power in 1290; Alauddin Khalji (born Juna Khan) ruled till 1316 [4]
3	Tughlaqs	1320–1414 [4]	Founded by Ghiyas-ud-din Tughlaq, who overthrew the Khaljis; Muhammad bin Tughlaq ruled 1325–1351 [4]
4	Sayyids	c. 1414–1451 [4]	Family claimed descent from the Prophet Muhammad ('sayyid') [4]
5	Lodis (Lodhis)	1451–1526 [4]	Afghan in origin; first ruler Bahlul Lodi (r. 1451–89), a Punjab chief [4]

• Why 'Mamluk' / 'Slave dynasty' — a mamluk was a soldier bought as a slave, trained for war, and later freed and promoted. Aibak himself rose this way. So the throne could pass to a general who had once been a slave.
• The Khiljis were also Turkic, but the Khalji tribe had long been settled in Afghanistan before coming to India [4].
• The Khalji period turned Delhi into an imperial power by pushing rule into the south [4]. This matches the NCERT point that Delhi took a bigger role in politics.
• Muhammad bin Tughlaq's reign was both the peak and the start of the fall of the Sultanate [4].

Resistance: Delhi was never the whole of India

• Eastern Gangas in the east and the Hoysalas in the south blocked Delhi's advance.
• These kingdoms were not just military rivals. They thrived as centres of art, culture and administration on their own.
• Lesson for the exam: "Delhi Sultanate" does not mean one empire over all India. Large parts stayed under independent Indian rulers.

Chronic instability — the core character of the rule

• Violent succession was the norm. Almost two sultans out of three took power by killing or removing the ruler before them.
• Average reign was barely nine years. Break this down:
• A new sultan spent his early years crushing rivals, not building.
• Nobles and generals knew a coup could work, so plotting paid off.

• Policies changed with every sultan, so long plans rarely survived.

• Campaigns were destructive. Armies raided villages and cities, took plunder, and destroyed temples and seats of learning — meaning libraries, schools and monasteries, not just shrines.

Monuments: the Qutub Minar complex

• The Qutub Minar complex is the signature building project of early Sultanate rule.
• The Quwwat-ul-Islam mosque — the name means 'Might of Islam' — was begun under Qutb-ud-din Aibak in the early 13th century and finished by later sultans.
• An inscription there states the mosque used materials from 27 destroyed Hindu and Jain temples.
• External detail: ASI dates the Quwwat-ul-Islam mosque to AD 1198 and calls it the earliest surviving mosque built by the Delhi Sultans [2].
• Qutb Minar itself: foundation laid by Aibak in AD 1199, built so the mu'azzin (the man who calls people to prayer) could give the call from a height. Aibak raised only the first storey; Iltutmish (AD 1211–36), his son-in-law and successor, added three more storeys [2].
• Size: red sandstone tower, 72.5 m high, 14.32 m wide at the base, narrowing to 2.75 m at the top, with alternating angular and rounded flutings (the up-and-down ribs on the outside wall) [3].
• The complex is a UNESCO World Heritage Site ("Qutb Minar and its Monuments, Delhi") and also holds the Alai Darwaza gateway (built 1311), the madrasa of Alauddin Khalji, the tomb of Iltutmish, the Alai Minar and the Iron Pillar [3].

Note: UNESCO's description says the Quwwat-ul-Islam mosque was built of materials reused from "some 20 Brahman temples" [3], while the NCERT scaffold gives the inscription figure of 27 Hindu and Jain temples. Use the NCERT figure of 27 in the exam.

Who paid for the luxury

• The sultans and the court elite lived in great comfort. Three sources of money funded it:
• Plunder taken in war.
• Taxes squeezed from common people and from conquered regions.

• The slave trade — enslaved people either gave free labour at home or were sold far away in Central Asia.

• The trap in this model: plunder itself broke the thing that produced wealth.

• Raided trade networks meant merchants stopped moving goods.
• Raided agriculture meant fields and villages produced less.
• So each round of plunder shrank the base for the next round of taxes.

Prelims Hooks

• Order of the five dynasties: Mamluk → Khilji → Tughlaq → Sayyid → Lodi.
• NCERT dates the Sultanate's formation from the defeat of Prithviraj Chauhan, 1192.
• Quwwat-ul-Islam means 'Might of Islam'; begun under Qutb-ud-din Aibak, dated AD 1198 by ASI; earliest surviving mosque of the Delhi Sultans [2].
• Its inscription records use of material from 27 destroyed Hindu and Jain temples.
• Qutb Minar: foundation AD 1199 by Aibak (first storey only); three storeys added by Iltutmish, AD 1211–36; built for the mu'azzin's call to prayer [2].
• Qutb Minar dimensions: 72.5 m tall, base 14.32 m, top 2.75 m, red sandstone [3].
• Alai Darwaza built in 1311; the complex also has Alauddin Khalji's madrasa, Iltutmish's tomb, the Alai Minar and the Iron Pillar [3].
• Khalji dynasty founded by Jalal-ud-din Firuz Khalji in 1290; Alauddin Khalji died 1316 [4].
• Tughlaqs 1320–1414, founded by Ghiyas-ud-din Tughlaq; Muhammad bin Tughlaq r. 1325–1351 [4].
• Lodis 1451–1526, Afghan origin, first ruler Bahlul Lodi (r. 1451–89) [4].
• Instability marker: nearly 2 out of 3 sultans seized power by eliminating the previous ruler; average reign about nine years.
• Kingdoms that resisted Delhi: Eastern Gangas (east), Hoysalas (south).

Mains Points

• Instability was structural, not accidental. With no fixed rule of succession, force decided who ruled. Nearly two in three sultans killed their way to the throne and reigns averaged nine years. Link this to weak long-term administration, heavy reliance on loyal slave-soldiers and nobles, and the speed with which the Sayyids and Lodis lost ground before 1526.
• A plunder economy eats itself. Court luxury rested on plunder, taxes and the slave trade, but the same raiding damaged trade routes and farming. Useful for GS-I questions on why Sultanate wealth did not translate into lasting economic growth — contrast with the settled revenue systems of later regimes.
• "Delhi Sultanate" is not "all-India rule". The Eastern Gangas and Hoysalas held out and flourished as centres of art and administration. Use this against the exam trap of treating 1206–1526 as one uniform empire; the Khalji southern push [4] shows ambition, not permanent control.
• Monuments carry two readings at once. The Qutub Minar complex — a 72.5 m tower [3], a UNESCO World Heritage Site — is both a high point of building skill and a record of destruction, since its mosque inscription names 27 demolished Hindu and Jain temples. Good for balanced answers on the cultural record of the period: art history and the cost at which it was made must be stated together.
