Timur’s Invasion of Delhi, 1398

Delhi’s own gates were opened to him from the inside.

Five days later, the city that had ruled most of India for two centuries lay in ruins. The sultanate that built it never fully recovered.

1. Timur’s March to Delhi

1.1 Who actually was Timur, before he ever reached India?

Timur, also known as Tamerlane, had spent decades building his own steppe empire across Central Asia from his capital at Samarkand. He called himself Sahib-i-Qiran, Lord of the Auspicious Conjunction, rather than khan, since he lacked the Genghis Khanid bloodline that title required. A conqueror who cannot claim the one title that would make his rule automatically legitimate has to build legitimacy some other way. Timur did it through military success on a scale few rulers of his era could match.

1.2 Why did he actually decide to invade Delhi in 1398?

Timur crossed the Indus River on 30 September 1398 with a force of roughly 92,000 cavalry. He advanced through Tulamba and Multan on his way toward Delhi. He justified the invasion partly on religious grounds, accusing the Delhi Sultanate’s rulers of tolerating non-Muslim subjects too freely. A ruler this far from home still needs some public justification for invasion, beyond plunder alone. Religious framing gave Timur exactly that, whatever his deeper motives actually were.

1.3 What did Timur’s forces actually do just before the battle?

Before the main battle, Timur ordered the execution of roughly 100,000 prisoners his army had captured along the march. Muslim captives were spared, but non-Muslim ones were killed. He recorded this himself in his own memoir, the Malfuzat-i-Timuri, framing it as a security measure. He judged that guarding so many prisoners during battle risked an uprising in his own camp. A commander does not record an act like this in his own memoir to seek forgiveness for it. Timur presented it as sound military judgment, and expected his readers to see it the same way.

2. The Battle of Delhi

2.1 Who did Timur actually face at Delhi, and why did elephants matter?

On 17 December 1398, Timur’s forces met the army of Sultan Nasir-ud-din Mahmud Shah Tughlaq outside Delhi. The sultan’s forces included war elephants, animals that could panic enemy cavalry simply by advancing. Most horses had never been trained to stand against them. An army facing elephants for the first time risks losing the battle before real fighting even starts, purely from its own horses bolting in fear.

2.2 How did Timur’s forces actually neutralise that elephant advantage?

Timur’s forces dug trenches in front of their own position and used fire and camels loaded with combustible material to panic the elephants before they could close the distance. A startled elephant will often turn and trample its own side while fleeing, which is exactly what happened here. Timur did not need to defeat the elephants in open combat. He only needed to turn them into a weapon that worked against Mahmud Shah’s own army instead.

2.3 What actually happened to Sultan Mahmud Shah’s forces?

With his elephants turned against his own lines and his army in disarray, Sultan Mahmud Shah Tughlaq’s forces broke, and the sultan himself fled Delhi. Timur’s army entered the city shortly after, with no organised defence left to resist them. A sultanate’s capital falls fastest not when its walls are breached, but when the ruler meant to defend it has already fled the field.

3. The Sack and Its Toll

3.1 What actually happened to Delhi over those five days?

Timur’s forces sacked Delhi over roughly five days, killing large numbers of its residents and looting the city’s accumulated wealth. Contemporary accounts describe the scale of destruction as among the worst Delhi suffered in its medieval history. A five-day sack, rather than a single day of plunder, reflects how much wealth and population a two-century-old imperial capital had actually accumulated by 1398.

3.2 Why did Timur specifically take Delhi’s artisans captive?

Timur’s forces rounded up many of Delhi’s skilled artisans and craftsmen and took them back to Samarkand as captives. Many were later put to work on Timur’s own building projects there, including the Bibi-Khanym Mosque. Skilled craftsmen were a form of plunder just as valuable as gold to a ruler planning to build monuments of his own. Timur clearly understood that, and took Delhi’s best artisans along with its treasure.

4. Why Timur Left, and What He Left Behind

4.1 Why did Timur actually withdraw so quickly, instead of ruling India himself?

Timur took his plunder and captives and returned toward Central Asia within weeks of sacking Delhi. He did not stay to govern any part of India directly. Samarkand lay thousands of kilometres away across difficult terrain, far too distant to administer a conquered Indian territory effectively. A ruler who cannot realistically defend or govern a distant conquest gains more by extracting its wealth quickly than by trying to hold it. Timur judged, correctly, that occupying Delhi long-term would cost him more than it was worth.

4.2 How did this invasion actually reshape the map of northern India?

Timur’s invasion left the Delhi Sultanate badly weakened, and regional governors used that weakness to declare their own independence within a decade. The Malwa Sultanate and the Gujarat Sultanate, both covered elsewhere on this site, emerged this way, founded by former Delhi Sultanate governors. A distant invasion that never intended permanent conquest can still permanently fracture an empire. Once a central authority is shown to be this vulnerable, its own governors rarely wait long before acting on it themselves.

4.3 Who actually filled the power vacuum Timur left behind at Delhi?

Timur appointed Khizr Khan as governor of Multan and Lahore before withdrawing. Khizr Khan later marched on Delhi himself and, in 1414, founded the Sayyid dynasty there, ruling a Sultanate now far smaller and weaker than before. He avoided calling himself Sultan outright at first, using lesser titles instead out of caution toward his own former Timurid overlords. A governor installed by a foreign conqueror does not automatically inherit that conqueror’s authority once he seizes the throne himself. Khizr Khan’s caution with titles shows he understood exactly how fragile his own legitimacy actually was.

5. What the PYQs Keep Testing

5.1 What kinds of facts do PYQs test about Timur’s invasion?

Exams on this invasion consistently test the same handful of facts. The 1398 date, the elephant-neutralising tactic at the Battle of Delhi, and the fate of Delhi’s captured artisans. Also why Timur withdrew instead of staying, and which dynasty and sultanates followed in its wake. Timur’s Delhi campaign remains part of the Tughlaqabad Fort story as well. The fort is linked to the dynasty that his invasion helped bring down. It was the subject of a 2024 Delhi High Court order for the removal of encroachments around its walls. That keeps the site in current news even today.
