The Battle of Kili was fought in 1299 between the Mongols of the Chagatai Khanate and the Delhi Sultanate. The Mongols, led by Qutlugh Khwaja, invaded India, intending to conquer Delhi. When they encamped at Kili near Delhi, the Delhi Sultan Alauddin Khalji led an army to check their advance. Alauddin's general Zafar Khan attacked a Mongol unit led by Hijlak without Alauddin's permission. The Mongols tricked Zafar Khan into following them away from Alauddin's camp, and then ambushed his unit. Before he died, Zafar Khan managed to inflict heavy casualties on the Mongol army. The Mongols decided to retreat after two days.

In 1303, a Mongol army from the Chagatai Khanate launched an invasion of the Delhi Sultanate, when two major units of the Delhi army were away from the city. The Delhi Sultan Alauddin Khalji, who was away at Chittor when the Mongols started their march, returned to Delhi in a hurry. However, he was unable to make adequate war preparations, and decided to take shelter in a well-guarded camp at the under-construction Siri Fort. The Mongols, led by Taraghai, besieged Delhi for over two months, and ransacked its suburbs. Ultimately, they decided to retreat, having been unable to breach Alauddin's camp. The invasion was one of the most serious Mongol invasions of India, and prompted Alauddin to take several measures to prevent its recurrence. He strengthened military presence along the Mongol routes to India, and implemented economic reforms to ensure adequate revenue streams for maintaining a strong army.

The 2010 Jama Masjid attack occurred on 19 September 2010 when two gunmen on a motorcycle fired at a tourist bus near Gate 3 of the Jama Masjid in Old Delhi, India and injured two Taiwanese tourists. The incident provoked fears about security for the upcoming Commonwealth Games in Delhi. About three hours later a car parked approximately 150 meters from the spot caught fire, apparently due to a minor blast.Two bike-borne gunmen opened fire at a stationary tourist bus purportedly carrying a TV crew from Taiwan at 11:24 pm, near Gate 3 of Jama Masjid. An explosive-laden device was planted in a Maruti 800 car, parked near a transformer near the mosque. The car had approximately 20 litres of fuel in its tank, which would have caused considerable damage if it had exploded successfully, but bomb timers failed and it did not go off. There were two victims of the shootout, Zeseweiu (27) and Chiang (28), both Taiwanese citizens. Zeseweiu head was grazed by a bullet while trying to escape, while Chiang was shot in the abdomen and had to be operated on. Both were declared to be out of danger the next day when the state CM and Union Home Minister paid them a visit.

On 6 June 2006, two explosions occurred in the courtyard of Jama Masjid, a 17th-century mosque in Old Delhi (India). The first blast took place at 17:26 local time right in the middle of the courtyard next to Wazoo Khana which comprises a pond where worshipers wash their hands and feet before offering prayers, and the second a few meters away seven minutes later. At least thirteen people were injured in the blasts. The blasts took place just before the call to prayer (azaan). The explosives were reportedly carried in plastic bags. There were around 1000 people in the mosque at the time of blasts as the day happened to be Friday, considered holy by the Muslims as well as being the first Friday after Mawlid, the birthday of the Islamic prophet Muhammad. The explosions did not cause any damage to the mosque. The Delhi government announced an ex gratia compensation of Rs. 50,000 to those with serious injuries and Rs. 25,000 to those with minor injuries.Some sources claim that the mosque was almost empty with only 100–150 people in the premises when the blast took place. The first blast occurred near Gate No. 1, a place where people wash their hands before offering prayers. It was the first attack of its kind on the historic mosque. It is being speculated that these blasts might be linked with coincidental six grenade attacks in Srinagar, that took place the same day.According to Delhi police, these were "low-intensity blasts" triggered by crude explosives. The police have not ruled out terrorist involvement. As of 7 June 2006, no terrorist group had claimed the responsibility of the blasts. The Delhi police have arrested four people and are questioning them for the blasts. Another school of thought suggests that the explosions could be the handiwork of some office bearers of the mosque due to internal rivalry.
