Mongol Invasions

Lore & Background

The campaign began in 1221 when Genghis Khan personally led the main force pursuing Jalal al-Din to the Indus River. In 1231, Jalal al-Din was killed by Kurdish bandits in Kurdistan, ending the Khwārazm-Shāh dynasty; he was never defeated by General Chormaqan in India. By 1241, a Mongol force invaded the Indus valley, besieging and sacking Lahore on December 30 before withdrawing following Ögedei's death. The Chagatai Khanate later dominated the frontier with near-constant hit-and-run raids between 1241 and 1306, targeting agricultural infrastructure in Multan, Sindh, and Lahore to cripple the Sultanate's economy.

In Their Own Story

In winter 1241, Munggetu led Mongol forces into the Indus valley, besieging Lahore before massacring the town on December 30. Decades later, the Chagatai Khanate under Duwa Khan intensified pressure on the northwest frontier. In 1292, Negudari governor Abdullah invaded Punjab with his son Ulghu's advance guard, only to be defeated and captured by Sultan Jalaluddin; 4,000 of these captives converted to Islam and settled in Delhi's new suburb, Mughalpura. The conflict escalated under Alauddin Khalji. In February 1298, his generals Ulugh Khan and Zafar Khan defeated Kadar at the Battle of Jaran-Manjur. Later, in late 1299, Duwa Khan dispatched his son Qutlugh Khwaja to conquer Delhi. At Kili, Alauddin's general Zafar Khan attacked without orders, fell into a Mongol feigned retreat, and was killed after inflicting heavy casualties. By August 1303, while Alauddin was away attacking Chittor, the Mongols launched another invasion. The Sultan rushed back to Delhi but found it unprotected, forcing him to take shelter in the heavily guarded camp at the under-construction Siri Fort as the invaders ransacked the city.

Reader's Guide

Historical records indicate that while chroniclers exaggerated Mongol numbers to 100,000–200,000 cavalry, actual armies likely ranged between 10,000 and 30,000, often organized into tumens of 10,000 men. Success against these forces required the Delhi Sultanate to organize its army to the highest efficiency under rulers like Ghiyas ud din Balban (r. 1266–1287), who refused to entrust authority to Hindus and stayed near his capital to counter invasion threats. A key turning point occurred in 1254–1255 when the Kashmiri king killed the appointed Buddhist master Otochi, prompting Möngke Khan's generals Sali and Takudar to invade, kill the king, and restore Mongol control over Kashmir for many years. In 1296–1297, Chagatai tumens were defeated multiple times by the Delhi Sultanate, demonstrating that while the Qara'unas and Chagatais launched persistent raids, they could be repelled with disciplined defense and rapid mobilization.

• The suburb of Lahore where 4,000 converted Mongol captives lived was named Mughalpura.
• Chroniclers like Minhaj-i-Siraj Juzjani recorded invasions of hundreds of thousands, though actual Mongol forces likely numbered between 10,000 and 30,000 cavalry.
• During the 1303 invasion, Alauddin Khalji was forced to seek shelter in a heavily guarded camp at the under-construction Siri Fort because Delhi itself was left unprotected.
• The Mongol leader Qutlugh Khwaja was never captured; after his failed attempt to trick Zafar Khan during a feigned retreat, he retreated to Afghanistan where he later died from wounds or illness.
