Cause

Mongol expansion into the Indian subcontinent began after Genghis Khan defeated Jalal al-Din at the Battle of the Indus in 1221. Subsequent incursions into the Punjab and Kashmir established Mongol presence in the region, and in the winter of 1241 a Mongol force again entered the Punjab, targeting Lahore, which was under Delhi Sultanate control.

Event

Mongol forces under Tair Bahadur besieged Lahore using siege engines to bombard its fortifications. The Delhi Sultanate's governor, Malik Qaraqash, withdrew before the main assault on 22 December 1241, leaving the city without effective defense. Mongol troops captured Lahore, killing a large number of inhabitants, enslaving others, and dismantling sections of the city walls.

Consequence

Following the sack of Lahore, the Mongol forces withdrew from the region without establishing permanent control. The Delhi Sultanate failed to mount any effective military response, hampered by internal political instability and factional disputes, exposing the vulnerability of its northwestern frontier to future Mongol incursions.
