Frequently asked questions

Muhammad ibn Tughluq was the Sultan of Delhi from 1325 to 1351, a ruler who was both learned and deeply controversial. What makes him singular is his unbounded ambition: he attempted to move the capital from Delhi to Daulatabad (over 900 miles away), introduced a copper currency that ruined the economy, and launched military expeditions as far as China. To understand his importance, one must remember that his reign marks both the peak and the decline of the Delhi Sultanate — his reforms, however visionary, were so poorly executed that they caused famines, revolts, and the loss of the southern provinces.

Key Facts

Works & Achievements

Monetary reform: introduction of the copper tanka (c. 1329)

Muhammad ibn Tughluq had copper coins minted to replace silver, hoping to multiply the sultanate's resources without depleting its precious metals. The experiment quickly failed due to widespread counterfeiting and had to be abandoned at great cost to the treasury.

Transfer of the capital to Daulatabad (1327)

A pharaonic project aimed at shifting the sultanate's centre to the Deccan in order to better control southern India. The forced march of Delhi's entire population over 1,500 km is remembered as one of the most controversial acts of his reign.

Construction of the city of Jahanpanah (c. 1326–1327)

The fourth city of Delhi built by Muhammad ibn Tughluq, Jahanpanah linked the older parts of the city into a single fortified whole. It stands as a testament to his urban ambitions before his plans to relocate the capital took over.

Agrarian reform and increase of the kharaj in the Doab (c. 1333)

An attempt to boost state revenues by doubling the land tax on the fertile plains between the Ganges and the Yamuna. Poorly implemented during a period of drought, it triggered famine, revolts, and the abandonment of farmland by peasants.

Military expedition toward China and Khorasan (1337–1338)

Muhammad ibn Tughluq raised an army of several tens of thousands of men to extend his empire as far as China. The expedition ended in military disaster in the Himalayas, costing the lives of nearly the entire army sent.

Anecdotes

In 1327, Muhammad ibn Tughluq made the astonishing decision to move the capital from Delhi to Daulatabad, more than 1,500 kilometres to the south. He ordered the entire population — nobles, merchants, artisans, and beggars alike — to abandon everything and march to the new capital. Ibn Battuta reports that residents who refused to leave were forced out. A few years later, the sultan reversed the decision himself: Daulatabad was abandoned and Delhi repopulated, but the double migration had exhausted and impoverished the country.

To finance his campaigns without depleting his gold and silver reserves, Muhammad ibn Tughluq introduced around 1329 a copper currency intended to replace silver coins. But the sultan found no way to prevent counterfeiting: almost anyone could strike copper coins at home. The currency lost all value, the treasury was flooded with forgeries, and the sultan was forced to reimburse in real silver everyone who returned their copper coins to him — further ruining the sultanate's finances.

Ibn Battuta, the great Berber traveller of the 14th century, spent several years at the court of Muhammad ibn Tughluq, who appointed him qadi (judge) of Delhi. In his memoirs, he describes a sultan of considerable learning who had mastered philosophy, mathematics, and medicine, and was capable of scholarly debate in Persian and Arabic. Yet he also bears witness to terrible fits of rage: public executions were frequent, even for minor offences, and those around the sultan lived in constant fear of falling from favour.

In 1337, Muhammad ibn Tughluq dispatched an army of several tens of thousands of men toward China, through the Himalayan passes. The expedition ended in disaster: ambushed in the mountains by local peoples, the army was almost entirely destroyed. This rout cost the sultanate a fortune in men and equipment, illustrating the tragic gap between the sultan's boundless ambitions and the realities of his time.

Primary Sources

Rihla (Travels) by Ibn Battuta (c. 1355)
Sultan Muhammad ibn Tughluq is the most generous ruler in India toward foreigners, yet also the quickest to punish. His gates are never closed to petitioners or criminals alike, and one may see at the same time those who are tortured and those who are rewarded.
Tarikh-i-Firuz Shahi by Ziauddin Barani (c. 1357)
The sultan, in his desire to subjugate the entire world, scattered his armies to the four corners of the earth and emptied his treasury in endless expeditions. His projects, though grandiose, brought ruin to the sultanate rather than glory.
Futuh-us-Salatin by Isami (c. 1350)
When the sultan ordered the transfer of the capital to Daulatabad, not a single house remained inhabited in Delhi. The entire city was emptied of its people, as though death itself had breathed upon it.
Masalik al-Absar by Ibn Fadlallah al-Umari (c. 1340)
Muhammad ibn Tughluq is a sultan said to be learned in philosophy, logic, and mathematics, speaking Persian and Arabic with ease, yet whose tyranny is feared by all his subjects.

Key Places

Delhi

The sultanate's main capital, Delhi was the political center of Muhammad ibn Tughluq both before and after the aborted attempt to relocate to Daulatabad. The city endured a forced exodus and subsequent repopulation, and bears witness to his reign through the city of Jahanpanah that he had built there.

Daulatabad (formerly Devagiri)

A Deccan fortress chosen by Muhammad ibn Tughluq as his new capital in 1327. The project forced the entire population of Delhi to march 1,500 km, but was abandoned a few years later, leaving the city half-empty.

Warangal (Andhra Pradesh)

A city in the Deccan conquered during the Tughluq dynasty's reign, it reflects the sultanate's military expansion into southern India in the period leading up to Muhammad ibn Tughluq's rule.

Sindh (present-day Pakistan)

A province in northwestern India where Muhammad ibn Tughluq died in 1351 during a military campaign against rebel tribes, bringing an end to a reign of twenty-six years.

Nagarkot (Kangra, Himachal Pradesh)

A Himalayan region through which the Tughluq army attempted to pass during the disastrous expedition toward China in 1337, where it was met by hostile mountain peoples who nearly annihilated the entire force.
