Causes for the Decline of the Delhi Sultanate
Medieval History › The Delhi Sultanate · Topic 2.15
The Delhi Sultanate declined because of lasting problems of the age, namely a struggle between monarch and nobles, conflict with local rulers and zamindars, and regional pull, which Muhammad bin Tughlaq's overreach and Firoz Shah's concessions made worse. Timur's invasion of 1398 ended strong Delhi rule, and the Lodis were the last dynasty.

Where Does It Fit?
This is the last topic of the category on the Delhi Sultanate. The earlier topics told the story and structure of the Sultanate, and this topic joins them into an explanation of its breakup. The next category covers the regional kingdoms that replaced it, starting with the Bahmani kingdom. Previous topic: Ibn Battuta’s Account of the Delhi Sultanate Period.
Can One Ruler Be Blamed?
In short: the decline of the Delhi Sultanate cannot be blamed on one ruler, because it grew out of lasting problems of medieval rule that individual sultans could not fix.
The persistent problems were the relations between the monarch and the nobles, the conflict with local rulers and zamindars, and the pull of regional and geographical factors. Individual rulers tried to deal with them, but none could bring about the basic change in society that was needed to offset these forces. Disintegration was always just below the surface, and any weakness in the central government set off a chain of events leading to breakup.
What Were the Causes of Decline?
| Cause | Explanation |
|---|---|
| Over-extension of the empire | The empire grew to Madurai under Muhammad bin Tughlaq, which created tremendous administrative and financial problems |
| Rebellions | Rebellions in Bengal, Mabar, Warangal, Kampili, Awadh, Gujarat and Sindh wore the army out |
| Plague and defeat | Two-thirds of the army perished in a plague in the south, a blow Muhammad never recovered from |
| Regional states | Vijayanagara, the Bahmani kingdom and Bengal became independent |
| Nobles with no cohesion | Muhammad’s nobility came from many groups with no loyalty; Firoz’s grants of heredity made them too strong |
| Army and iqta | Hereditary posts and land assignments for soldiers made the army inefficient |
| Local chiefs | Rajas and zamindars used every weakness at the centre to assert independence |
| Slave corps | After Firoz’s death, the Firuzi slaves tried to place their own man on the throne |
What Did the Policies of Individual Sultans Do?
Muhammad bin Tughlaq’s reign was the zenith of the Sultanate and also the beginning of its disintegration. His experiments strained the treasury and prestige, and his habit of dashing from one rebellion to another wore out his armies. He also clashed with theologians and Sufi saints. His unpopularity should not be exaggerated, since the administration in Delhi, Punjab and the north kept working even when he was away.
Firoz Shah tried to prevent the breakup by appeasing nobles, the army and theologians. He asserted his authority only over areas that could be easily governed from the centre, made posts and iqtas hereditary, ended torture for audit balances and paid soldiers by land assignments. His peaceful reign and canals brought development, but the reforms made the nobility too strong and the army inefficient. After him the sultans Muhammad and Nasiruddin Mahmud could not control ambitious nobles and rajas, and governors became independent.
How Did Timur’s Invasion Finish the Job?
Timur, a Turk related to Changez Khan, raided India in 1398 to seize the wealth the sultans had gathered over two centuries. With the Sultanate in collapse, no one met his army, which sacked towns on the way and then Delhi without mercy. He took away wealth, jewels and artisans to Samarqand. The direct political effect was small, but the invasion marks the end of the phase of strong rule by the Delhi sultans, though the Tughlaq line lingered until 1412. A wit said the sultan’s rule extended from Delhi to Palam.
How Should Students Answer This Question?
As an analytical point, a good answer separates structural causes from short-term ones. Structural causes are the weak link between the centre and the provinces, the hold of nobles over land and army, and regional feeling. Short-term causes are Muhammad’s over-extension, Firoz’s concessions and Timur’s raid. A balanced answer then notes that the Sultanate’s administrative system, in the iqta, the departments and the army, survived in the regional kingdoms and the Mughals.
