The Delhi Sultans — Study Notes

1. Introduction

Delhi, a city that is today the capital of India, has a long and glorious history. In the centuries between 1206 and 1526, it served as the capital of five successive dynasties that together are known as the Delhi Sultanate. These rulers brought the city to political prominence, established Persian as the language of administration, and created a system of government whose influence lasted for centuries.

The history of the Delhi Sultanate is the story of how a band of Turkish military commanders transformed a small frontier outpost into the capital of a vast empire. It is also the story of how rulers dealt with a diverse population, of how they collected taxes, and of how they came into contact with the wider Islamic world. Studying the Sultanate helps us understand the foundations of many administrative and political institutions that survived in India for centuries.

2. The Beginning of the Sultanate

The Delhi Sultanate began in 1206, when Qutbuddin Aibak, a former general of Muhammad Ghori, set himself up as the ruler of Delhi. Aibak was a slave (mamluk) of Muhammad Ghori and became the first ruler of the Slave dynasty (1206-1290). The Sultans of Delhi ruled for about 320 years, and the five dynasties of the period were the Slave dynasty, the Khalji dynasty, the Tughluq dynasty, the Sayyid dynasty, and the Lodi dynasty.

The term "Delhi Sultanate" is sometimes written with a capital S, because the word Sultan refers to a ruler, whereas "Sultanate" refers to the period or the state ruled by a Sultan. Delhi became the capital because of its strategic location on the trade routes and because it was protected on one side by the Aravalli hills.

4. Finding Out About the Delhi Sultans

Historians find out about the Delhi Sultans from a variety of sources. Inscriptions, coins, and architecture are important archaeological sources. Coins, in particular, are useful because they show the names of rulers, their titles, and sometimes even the dates of their reigns. Monuments like the Qutb Minar and the Jama Masjid give us information about the building activities of the rulers.

Literary sources include histories (tawarikh) written in Persian, which was the language of administration in the Sultanate. The most important of these is the Tabaqat-i-Nasiri by Minhaj-i-Siraj, written around 1260, which is dedicated to Sultan Nasiruddin Mahmud. Another famous work is the Ziya-ud-din Barani's Tarikh-i-Firuz Shahi, written during the reign of Firuz Shah Tughluq. In addition, travel accounts of visitors like Ibn Battuta, who came from Morocco in the fourteenth century, give valuable information about the Sultanate.

5. The Delhi Sultans and the Consolidation of Power

The Early Rulers: Iltutmish and Balban

Iltutmish (1210-1236) was the real founder of the Slave dynasty, defeating the Yalduz and Qubacha rivals. He shifted the capital from Lahore to Delhi and completed the building of the Qutb Minar. Iltutmish also introduced a new coinage system, with silver coins called tankas and copper coins called jitals, and he established the iqta system of land revenue administration.

Balban (1266-1287) was a powerful ruler who insisted on the dignity of the king and introduced elaborate court rituals. He believed that kings were God's shadow on earth and should not mix with ordinary people. Balban dealt firmly with the nobles and reorganised the army to defend the northwest frontier against Mongol attacks.

Alauddin Khalji

Alauddin Khalji (1296-1316) expanded the Sultanate to cover almost the whole of the Indian subcontinent, including large parts of the Deccan. He attacked the Mongol armies and defeated them, protecting the empire from Mongol invasions. To finance his wars, he introduced new market controls, fixing the prices of food grains, cloth, horses, and other goods, and he set up a strong military administration. Alauddin also built the famous Alai Darwaza and the Hauz-i-Khas reservoir near Delhi.

6. Muhammad Tughluq and His Experiments

Muhammad Tughluq (1324-1351) is one of the most discussed rulers of the Sultanate. He tried several grand projects: he shifted his capital from Delhi to Daulatabad in the Deccan, and he experimented with token currency, introducing copper and brass coins that were to be exchanged for silver tankas at face value. Both projects created problems. The shifting of the capital was later abandoned, and the token currency was misused, as many people began to counterfeit the coins.

Ibn Battuta has left a detailed account of Muhammad Tughluq's court, describing the Sultan as a man of great learning, poetry, and intelligence, but also noting the harsh punishments he gave. Historians view Muhammad Tughluq as a ruler of ideas who was ahead of his time, but whose schemes often failed due to poor planning and lack of resources.

7. The Administration of the Sultanate

The Iqta System

The most important administrative system of the Sultanate was the iqta system. The empire was divided into provinces called iqtas, and governors (muqtis or walis) were appointed to look after each iqta. The muqtis were paid salaries and were expected to collect taxes and maintain law and order within their iqtas. They were periodically transferred and could not hold the same territory permanently.

The Sultan, the Nobles, and the Ulema

The Sultan was the head of the state and commanded the army. Under him were the nobles (amirs), who helped him in administration. The ulema, or the learned men of the Muslim community, advised the Sultan on religious matters. The Sultan had to be careful to keep the nobles satisfied, and ambitious rulers kept them in check through strict discipline.

8. The "Slaves", the "Mongols" and the "Internal Frontier"

The term "slave" in the context of the Sultanate did not mean a slave in the modern sense. The slaves (bandagan) of the Delhi Sultanate were highly trained soldiers who could rise to high positions, even becoming rulers themselves, as Qutbuddin Aibak did. Iltutmish and Balban were both such slaves who became sultans.

The Sultanate had two "frontiers" to defend. The external frontier was against the Mongol armies, which repeatedly invaded from the northwest under rulers like Chengiz Khan and his successors. The internal frontier was against powerful landholders and rebels within the empire, especially the Hindu chieftains (muqaddams, khots, and chaudhuris) who controlled the villages and often refused to pay revenue. The Sultans had to continually struggle against both fronts.

9. The Decline of the Sultanate

The Sultanate declined in the fifteenth century for several reasons. The later Sultans were weak, and powerful nobles and governors became independent, breaking away from Delhi's control. Timur's invasion in 1398 destroyed Delhi and the surrounding region, causing enormous damage. By 1451, the Sayyid dynasty was replaced by the Lodi dynasty, and in 1526, Babur defeated Ibrahim Lodi at the first battle of Panipat, ending the Sultanate and beginning the Mughal Empire.

Common Mistakes

1. Confusing the Slave dynasty with the institution of slavery - the Sultanate's "slaves" (bandagan) were trained soldiers who could rise to high office and even become sultans.
2. Thinking that Iltutmish was the first Sultan of Delhi - Qutbuddin Aibak began the Sultanate in 1206, while Iltutmish consolidated it.
3. Believing that Muhammad Tughluq's token currency was a success - it was counterfeited heavily and had to be withdrawn.
4. Confusing the Tabaqat-i-Nasiri (by Minhaj-i-Siraj) with the Tarikh-i-Firuz Shahi (by Ziya-ud-din Barani) - know who wrote each.
5. Forgetting the order of the dynasties; use the memory aid - Slave, Khalji, Tughluq, Sayyid, Lodi.
6. Believing Balban was the first to introduce the iqta system; it was Iltutmish who introduced it.
7. Thinking that Delhi always had the same boundaries; the Sultanate's territory expanded and contracted, with the Deccan added under Alauddin Khalji.

Exam Tips

1. Memorise the five dynasties with their years and one key ruler each - this is a guaranteed exam question.
2. For Muhammad Tughluq, always present both sides: brilliant ideas but poor implementation.
3. Name specific sources: Tabaqat-i-Nasiri, Tarikh-i-Firuz Shahi, Ibn Battuta's Rihla.
4. Explain the iqta system in three points: division into provinces, muqti as governor, transfer after fixed terms.
5. Link Alauddin's market control to his military campaigns - he needed cheap goods for soldiers.
6. Remember the two frontiers - external (Mongols) and internal (landholders) - as a conceptual point.
7. For map work, know the locations of Delhi, Daulatabad, and Panipat.

Conclusion

The Delhi Sultanate transformed the political and cultural landscape of north India. From the first Sultan Qutbuddin Aibak to the last Lodi ruler Ibrahim Lodi, the Sultans built a powerful centralised state, developed the iqta system of administration, and patronised Persian learning and magnificent architecture. The period also saw constant challenges from Mongol invaders and rebellious landholders, and rulers like Alauddin Khalji and Muhammad Tughluq experimented boldly with administration and economics. Though the Sultanate declined after Timur's devastating invasion in 1398, its legacy of administration, coinage, and culture lived on and was inherited by the Mughal Empire that followed.
