After Mu'izz ad-Din's death in 1206, Qutb al-Din became the ruler of the Delhi Sultanate, which evolved independent of the former Ghurid Empire. In 1210, when Qutb al-Din Aibak died unexpectedly in
Lahore, the local nobles appointed
Aram Shah as his successor to prevent instability in the kingdom. However, the nobles in other parts of the Sultanate opposed this decision, and proposed Iltutmish as an alternative, because Aibak used to call him a son, and because he had a distinguished record of service. These nobles, led by the military justiciar (
Amir-i Dad) Ali-yi Ismail, invited him to occupy the throne. Iltutmish marched to Delhi, where he seized the power, and later defeated Aram Shah's forces. Some nobles rebelled against his seizure of power, but Iltutmish subjugated them, and had many of them beheaded. Minhaj-i-Siraj states that after Aibak's death, the former Ghurid dominions of India (
Mamalik-i-Hindustan) had been divided into four parts, centred at: • Delhi, controlled by Iltutmish • Sindh, controlled by
Nasir ad-Din Qabacha, a former Ghurid slave, who had been muqta (provincial governor) of
Uch since 1204 •
Lakhnauti, controlled by
Ali Mardan Khalji, a former governor who proclaimed independence and styled himself as Sultan Ala al-Din •
Lahore, contested between Qabacha,
Yildiz, and Iltutmish
Delhi's dependencies Several Muslim officers, who administered Delhi's dependencies during Aibak's reign, did not recognize Iltutmish's authority. According to
Minhaj, Iltutmish re-asserted Delhi's control over
Badaun,
Awadh,
Banaras, and
Siwalik in a series of campaigns. For example, Iltutmish captured Banaras after defeating Qaymaz, who was presumably a former officer of Aibak. By the time of Iltutmish's ascension, Delhi's hold over various
Hindu chiefs had weakened, and some of them - such as those of
Ranthambore and
Jalor - had declared independence. During the first few years of his reign, Iltutmish's other preoccupations appear to have prevented him from campaigning against these chiefs.
Hasan Nizami refers to an undated expedition against Jalor, which may have taken place sometime after his victory over Aram Shah.
Defeat of Yildiz The Ghurid capital of
Ghazni was controlled by
Taj al-Din Yildiz, a former slave who claimed to be the rightful successor to the Ghurid emperor. After Iltutmish suppressed the rival claimants to the throne, Yildiz sent him a royal umbrella (
chatr) and a baton (
durbash): these gifts implied that Iltutmish was a subordinate ruler. Iltutmish did not want an immediate confrontation, and accepted these gifts. Iltutmish's earliest inscription, dated October 1211, styles him as a subordinate king - ''al-Malik al-Mu'azzam
("the great chief"), rather than as an imperial Sultan''. Meanwhile, taking advantage of the succession conflict between Aram Shah and Iltutmish, Qabacha had captured Lahore in 1211. Shortly after this, a
Khwarazmian invasion forced Yildiz to leave Ghazni. Yildiz migrated eastwards, displaced Qabacha from Lahore, and captured parts of the
Punjab region. Iltutmish became concerned that Yildiz would ultimately try to occupy Delhi, and marched against him. Yildiz sent a message to Iltutmish, declaring that he was the real successor of Mu'izz ad-Din and thus, had claims to the former Ghurid territories in India. According to
Isami's
Futuh-us-Salatin, Iltutmish replied that the days of such hereditary claims were over: Iltutmish offered to engage in a negotiation provided both men came to the meeting unaccompanied by any warriors. Yildiz refused the offer, resulting a battle at
Tarain on 25 January 1216, which resulted in Iltutmish's victory. Isami states that Yildiz managed to escape to
Hansi, while the earlier chronicler
Hasan Nizami states that he was injured by an arrow and captured on the battlefield. Yildiz was later taken to Iltutmish's stronghold of
Badaun, where he was killed. Iltutmish's success in this conflict reinforced the Delhi Sultanate's independent status.
Initial conflict with Qabacha Iltutmish's victory over Yildiz did not result in any substantial increase in his territory. He did not immediately assert his control over the Punjab region, and Qabacha regained control of Lahore. By this time, Qabacha had assumed the sovereign title of Sultan, and controlled a vast territory that included coastal Sindh,
Siwistan, Bhakkar, and Multan. Subsequently, Qabacha tried to conquer a greater part of Punjab: according to
Firishta, he sought to extend his authority as far as
Sirhind in the east. This prompted Iltutmish to march against him in 1217. Qabacha initially retreated, but Iltutmish's army chased him and defeated him at a place called Mansura, which was located on the banks of the
Chenab River. Iltutmish then captured Lahore in the winter of 1216–1217, and appointed his son
Nasiruddin Mahmud to govern it. Lahore remained contested in the subsequent years; for example, at the time of Khwarazmian invasion of the region (see below), it was under the control of Qabacha's son. Qabacha seems to have posed a serious threat to Iltutmish, as suggested by
Muhammad Aufi in
Lubab ul-Albab. Aufi, writing shortly before the Khwarazmian invasion, expresses hope that his patron Qabacha will soon conquer the whole of Hindustan. Aufi also mentions that Ahmad Jamaji, who was Iltutmish's governor of
Bahraich, defected to Qabacha in 1220.
Khwarazmian threat The
Khwarazmshahs, who had taken over the western part of the former Ghurid Empire, suffered a
Mongol invasion in 1220. After being defeated at the
Battle of Indus in 1221, the Khwarazmshah
Jalal al-Din Mangburni escaped to the
Punjab region. He entered into a matrimonial alliance with the local
Khokhar chief Rai Khokhar Sankin, and defeated other regional rulers, including Qabacha. The Mongol leader
Genghis Khan briefly considered returning to Mongolia through a shorter route which involved crossing the Himalayan foothills. He sent envoys to Iltutmish, asking for the Delhi Sultan's permission to pass through India. No extant sources provide any information about the result of this embassy, but it appears that Genghis Khan abandoned his plan to pass through India. According to the Persian historian
Ata-Malik Juvayni, Genghis Khan advanced eastwards into India, but failed to find a suitable route, and therefore, exited the country via
Peshawar. It is possible that Genghis Khan, through his envoys, asked Iltutmish to not aid Jalal ad-Din: Iltutmish seems to have obliged. Meanwhile, Jalal ad-Din established himself in the
Sindh Sagar Doab in the Punjab region, and captured the fort of
Pasrur. He sent his envoy Ainul Mulk to Iltutmish, seeking an alliance against the Mongols, and requesting for a safe place to stay. According to Juvayni, after deliberating over the matter for several days, Iltutmish refused to provide him a residence on the excuse that no place in his kingdom have a suitable climate or a locality fit for a king. Iltutmish also had the envoy killed, and sent troops to aid Qabacha against Jalal ad-Din .
Minhaj, another Persian historian, states that Iltutmish himself led an army against Jalal ad-Din. Only the vanguards of the two armies clashed, and the two rulers withdrew after exchanging friendly messages. Meanwhile, Qabacha - who had earlier accepted Jalal ad-Din's suzerainty - rebelled against him, and this conflict kept Jalal ad-Din busy. Jalal-ad-Din carried out some more campaigns in India, including a raid in
Gujarat, but none against Iltutmish. He left the Indian frontier in 1223–1224; according to his biographer
Shihab al-Din Muhammad al-Nasawi, he did so because he received the news that Iltutmish, Qabacha, and several Hindu chiefs ("rais and thakurs") had formed an alliance against him. The Mongols also maintained a presence in the region: for example, Genghis Khan's general besieged Qabacha in Multan in 1224, before retreating because of hot weather. Until Genghis Khan's death in 1227, Iltutmish chose not to get involved in the politics of the Indus valley region to avoid a potential conflict with the Mongols. == Territorial expansion ==
