Mongol invasions and northern conquests, 1297–1306 In the winter of 1297, the
Mongols led by a
noyan of the
Chagatai Khanate raided Punjab, advancing as far as
Kasur. Alauddin's forces, led by Ulugh Khan,
defeated the Mongols on 6 February 1298. According to
Amir Khusrow, 20,000 Mongols were killed in the battle, and many more were killed in Delhi after being brought there as prisoners. In 1298–99, another Mongol army (possibly
Neguderi fugitives)
invaded Sindh, and occupied the fort of
Sivistan. This time, Alauddin's general
Zafar Khan defeated the invaders and recaptured the fort. In early 1299, Alauddin sent Ulugh Khan and Nusrat Khan to
invade Gujarat, where the
Vaghela king
Karna offered a weak resistance. Alauddin's army plundered several towns including
Somnath, where it desecrated the famous Hindu temple. The Delhi army also captured several people, including the Vaghela queen Kamala Devi and slave
Malik Kafur, who later led Alauddin's southern campaigns. During the army's return journey to Delhi, some of its Mongol soldiers staged an unsuccessful mutiny near
Jalore, after the generals forcibly tried to extract a share of loot (
khums) from them. Alauddin's administration meted out brutal punishments to the mutineers' families in Delhi, including killings of children in front of their mothers. According to
Ziauddin Barani, the practice of punishing wives and children for the crimes of men started with this incident in Delhi. In 1299, the Chagatai ruler
Duwa sent a Mongol force led by
Qutlugh Khwaja to conquer Delhi. In the ensuing
Battle of Kili, Alauddin personally led the Delhi forces, but his general Zafar Khan attacked the Mongols without waiting for his orders. Although Zafar Khan managed to inflict heavy casualties on the invaders, he and other soldiers in his unit were killed in the battle. Qutlugh Khwaja was also seriously wounded, forcing the Mongols to retreat, Qutlugh Khwaja later died on the way while retreating.
Conquest of northern India was captured by Alauddin Khalji in 1299 CE. Around the same time, Alauddin turned his attention towards the present-day state of Rajasthan to subdue the Rajput kingdoms for a secure base to
Gujarat and
Malwa and for further expeditions in the South. In 1299 CE, Alauddin besieged the
fortress of Jaisalmer ruled by
Bhatis at the time under Jait Singh I. Following a long siege and due to the dearth of food and resources, eventually, the besieged Rajputs under the command of Mularaja performed Saka where the women committed
Jauhar and the men fought until death. Thus, Alauddin successfully penetrated into territories of the Bhattis. After the conquest of Jaisalmer, it remained under the Khalji's for few more years. In 1301, Alauddin ordered Ulugh Khan and Nusrat Khan to
invade Ranthambore, whose king
Hammiradeva had granted asylum to the leaders of the mutiny near Jalore. After Nusrat Khan was killed during the siege, Alauddin personally took charge of the siege operations, and conquered the fort in July 1301. During the Ranthambore campaign, Alauddin faced
three unsuccessful rebellions. To suppress any future rebellions, he set up an intelligence and surveillance system, instituted a total
prohibition in Delhi, established laws to prevent his nobles from networking with each other, and confiscated wealth from the general public. in
Rajasthan, in the
Siege of Chittorgarh (1303). In the winter of 1302–1303, Alauddin dispatched an army to ransack the
Kakatiya capital
Warangal. Meanwhile, he himself led another army to conquer
Chittor, the capital of the
Guhila kingdom ruled by
Ratnasimha. Alauddin captured Chittor after an
eight-month long siege. According to his courtier Amir Khusrau, he ordered a massacre of 30,000 local Hindus after this conquest. Some later legends state that Alauddin invaded Chittor to capture Ratnasimha's beautiful queen
Padmini, but most modern historians have rejected the authenticity of these legends. While the imperial armies were busy in Chittor and Warangal campaigns, the Mongols launched another
invasion of Delhi around August 1303. Alauddin managed to reach Delhi before the invaders, but did not have enough time to prepare for a strong defence. Meanwhile, the Warangal campaign was unsuccessful (because of heavy rains according to
Ziauddin Barani), and the army had lost several men and its baggage. Neither this army, nor the reinforcements sent by Alauddin's provincial governors could enter the city because of the blockades set up by the Mongols. Under these difficult circumstances, Alauddin took shelter in a heavily guarded camp at the under-construction
Siri Fort. The Mongols engaged his forces in some minor conflicts, but neither army achieved a decisive victory. The invaders ransacked Delhi and its neighbourhoods, but ultimately decided to retreat after being unable to breach Siri. The Mongol invasion of 1303 was one of the most serious invasions of India, and prompted Alauddin to take several steps to prevent its repeat. He strengthened the forts and the military presence along the Mongol routes to India. He also implemented a series of
economic reforms to ensure sufficient revenue inflows for maintaining a strong army. '', a
Rajput painting from 1825 In 1304, Alauddin appears to have ordered a
second invasion of Gujarat, which resulted in the annexation of the Vaghela kingdom to the Delhi Sultanate. In 1305, he launched an
invasion of Malwa in central India, which resulted in the defeat and death of the
Paramara king
Mahalakadeva. The
Yajvapala dynasty, which ruled the region to the north-east of Malwa, also appears to have fallen to Alauddin's invasion. In December 1305, the Mongols invaded India again. Instead of attacking the heavily guarded city of Delhi, the invaders proceeded south-east to the
Gangetic plains along the
Himalayan foothills. Alauddin's 30,000-strong cavalry, led by Malik Nayak, defeated the Mongols at the
Battle of Amroha. Many Mongols were taken captive and killed; the 16th-century historian
Firishta claims that the heads (
sir) of 8,000 Mongols were used to build the Siri Fort commissioned by Alauddin. In 1306, another Mongol army sent by Duwa advanced up to the
Ravi River, ransacking the territories along the way. Alauddin's forces, led by
Malik Kafur, decisively
defeated the Mongols. Duwa died next year, and after that the Mongols did not launch any further expeditions to India during Alauddin's reign. On the contrary, Alauddin's
Dipalpur governor
Malik Tughluq regularly raided the Mongol territories located in present-day Afghanistan.
Marwar and southern campaigns, 1307–1313 Around 1308, Alauddin sent Malik Kafur to
invade Devagiri, whose king
Ramachandra had discontinued the tribute payments promised in 1296, and had granted asylum to the Vaghela king Karna at
Baglana. Kafur was supported by Alauddin's Gujarat governor Alp Khan, whose forces invaded Baglana, and captured Karna's daughter
Devaladevi (later married to Alauddin's son Khizr Khan). At Devagiri, Kafur achieved an easy victory, and Ramachandra agreed to become a lifelong vassal of Alauddin. Meanwhile, a section of Alauddin's army had been besieging the fort of
Siwana in
Marwar region unsuccessfully for several years. In August–September 1308, Alauddin personally took charge of the siege operations in Siwana. The Delhi army conquered the fort in the
Siege of Siwana, and the defending ruler Sitaladeva was killed in November 1308. The plunder obtained from Devagiri prompted Alauddin to plan an invasion of the other southern kingdoms, which had accumulated a huge amount of wealth, having been shielded from the foreign armies that had ransacked northern India. In late 1309, he sent Malik Kafur to ransack the
Kakatiya capital
Warangal. Helped by Ramachandra of Devagiri, Kafur entered the Kakatiya territory in January 1310, ransacking towns and villages on his way to Warangal. After a month-long
siege of Warangal, the Kakatiya king
Prataparudra agreed to become a tributary of Alauddin, and surrendered a large amount of wealth (possibly including the
Koh-i-Noor diamond) to the invaders. Meanwhile, after conquering Siwana, Alauddin had ordered his generals to subjugate other parts of Marwar, before returning to Delhi. The raids of his generals in Marwar led to their confrontations with
Kanhadadeva, the
Chahamana ruler of
Jalore. In 1311, Alauddin's general
Malik Kamaluddin Gurg captured the Jalore fort after defeating and killing Kanhadadeva. During the siege of Warangal, Malik Kafur had learned about the wealth of the
Hoysala and
Pandya kingdoms located further south. After returning to Delhi, he took Alauddin's permission to lead an expedition there. Kafur started his march from Delhi in November 1310, and crossed
Deccan in early 1311, supported by Alauddin's tributaries Ramachandra and Prataparudra. ) at the center, in the

Diogil floats a peculiar flag (), while coastal cities are under the black flag of the
Delhi Sultanate (). Devagiri was ultimately captured by Alauddin Khalji in 1307. The trading ship raises the flag of the
Ilkhanate (). At this time, the Pandya kingdom was reeling under a war of succession between the two brothers Vira and Sundara, and taking advantage of this, the Hoysala king
Ballala had invaded the Pandyan territory. When Ballala learned about Kafur's march, he hurried back to his capital
Dwarasamudra. However, he could not put up a strong resistance, and negotiated a truce after a
short siege, agreeing to surrender his wealth and become a tributary of Alauddin. From Dwarasamudra, Malik Kafur marched to the Pandya kingdom, where he
raided several towns reaching as far as
Madurai. Both Vira and Sundara fled their headquarters, and thus, Kafur was unable to make them Alauddin's tributaries. Nevertheless, the Delhi army looted many treasures, elephants and horses. The Delhi chronicler
Ziauddin Barani described this seizure of wealth from Dwarasamudra and the Pandya kingdom as the greatest one since the Muslim capture of Delhi. During this campaign, the Mongol general Abachi had conspired to ally with the Pandyas, and as a result, Alauddin ordered him to be executed in Delhi. This, combined with their general grievances against Alauddin, led to resentment among Mongols who had settled in India after converting to Islam. A section of Mongol leaders plotted to kill Alauddin, but the conspiracy was discovered by Alauddin's agents. Alauddin then ordered a
mass massacre of Mongols in his empire, which according to Barani, resulted in the death of 20,000 or 30,000 Mongols. Meanwhile, in
Devagiri, after Ramachandra's death, his son tried to overthrow Alauddin's suzerainty. Malik Kafur invaded Devagiri again in 1313, defeated him, and became the governor of Devagiri. == Administrative changes ==
