Corps of Forty
The Corps of Forty, historically known as the Shamsi Bandagan and also known as the Turkan-e-Chihilgani, was a council of 40 mostly Turkic slave emirs who administered the Delhi Sultanate as per the wishes of the sultan. However, their number was not always 40, as Minhaj-i Siraj Juzjani says the group numbered 25 for some time.
It was initially formed by Shamsuddin Iltutmish, the third ruler of the Mamluk dynasty. After Iltutmish's death, the balance of power shifted and the sultan became a puppet of these emirs. They would enthrone and depose Iltutmish's children and grandchildren, often murdering them when they proved troublesome. Balban, one of Iltutmish's slaves and a former member of the Corps, broke the power of the emirs and restored the power and stature of the sultan. This destruction of the Corps would prove to be a double-edged sword. Without the Chihilgani around to maintain a Turkic monopoly on power, this left them vulnerable to the Khalji faction, which took power through a series of assassinations, and ultimately overthrew the Turks during the Khalji Revolution. The Turkan-i-Chihilghani were broken up, and they fled to and settled down in different villages in the region of Katehar, also known as Rohilkhand.

Historian Peter Jackson notes that the medieval chronicler Minhaj-i Siraj Juzjani provides biographies of 25 Shamsi Turkish slaves. Jackson notes that there was only one Indian among the 25 Shamsi owned by Iltutmish and listed by Juzjani, namely Hindu Khan, who probably was in charge of all the other Shamsi slaves and held the title of the mihtar-i mubārak. The Turkic Shamsi slaves were drawn from, among others, Rumis and Khitans. The Rumi slaves were 'Izz al-Din Kabir Khan Ayaz, Badr al-Din Sonqur and Nusrat Khan Badr al-Din Sonqur. The Khitan slaves were Sayf al-Din Aybeg, also called Yaghantut ; and Sayf al-Din Ikit Khan Aybeg-i Khita'i. The Qara Khitai slaves were 'Izz al-Din Toghril Toghan Khan, Ikhtiyar al-Din Aytegin Qaraqush Khan, and Ikhtiyar al-Din Aytegin.There were many Kipchak slaves among the Shamsi. These include Qamar al-Din Qiran Temur Khan; Taj al-Din Sanjar, also known as Qabaqulaq ; Taj al-Din Sanjar *Kirit Khan; Ikhtiyar al-Din Yuzbeg Toghril Khan; 'Izz al-Din Balaban, later known as Küshlü Khan; Sayf al-Din Aybeg Shamsi-yi 'Ajami. Küshlü Khan was purchased during the siege of Mandore in 1227. There were also notable slaves drawn from the group Iltutmish belonged to, the Olberli, who were a subdivision of either the Kipchaks or the Qanglïs. Historian Sunil Kumar posits that the Olberli were Yemek Turks. The Olberli slaves among the Shamsis were Baha al-Din Balaban, who later became the sultan; his brother Sayf al-Din Aybeg, later known as Kishli Khan; and their cousin Nusrat al-Din Sanjar, also known as Shir Khan. Balaban was purchased in 1231/1232 ; his brother Kishli Khan was bought the same year during an embassy sent by Iltutmish to Egypt and Baghdad. Taj al-Din Sanjar, was also purchased during this embassy. Arslan Khan was also probably a Karakhitai Turk. Other Shamsi slaves whose tribal backgrounds are not known are Taj al-Din Sanjar *Kezlik Khan, Nasir al-Din Aytemur al-Bahai, Saif al-Din Aybeg-i Uchch and Nusrat al-Din Tayisi al-Mu'izzi.
Feudal performance
The area of Bayana is said to have prospered due to its administration by Bahauddin Tughril, who first became its holder in 1196. The regions granted to Sayf al-Din Aybeg Shamsi-yi 'Ajami, according to Barani, became prosperous. *Kezlik Khan at Uch is known to have worked for the welfare and security of the peasantry. Barani lauds Balaban for the prosperity he achieves in his fiefs, and Juzjani says he focused a lot on agricultural issues when he arrived in Hansi. Holders of fiefs who were required in Delhi did not usually go to their iqta'History
In Delhi
During the reign of Iltutmish, these amirs were granted Turkish titles, including the title of khan, a title not held by Ghurid or Tajik nobles. Some Shamsi had previously been slaves of other commanders, however, most of them were purchased from slave traders. Traveler Ibn Battuta has related an account about Iltutmish sending merchants to Samarkand, Bukhara and Termez to purchase Turkish slaves for him. Their purchases dates are spread out over a long period of time, starting from the time Iltutmish held the iqta of Baran. In 1231, Kabir Khan Ayaz became the first Shamsi whose fiefs were downgraded, when he was transferred from Multan to the small town of Palwal. The fief of Multan was then transferred to another Shamsi, Ikhtiyar al-Din Qaraqush Khan Aytegin.The contemporary medieval chronicler Ziauddin Barani, after the death of Iltutmish, had taken notice of how each Shamsi had demanded he be given similar iqta'
Razia Sultana enjoyed the strong support of the Shamsi, however, she soon started building her own group of supporters. After the death of Sayf al-Din Aybeg-i *Tutuq in 1237, the Turkic deputy army commander, she did not choose a Turk as his successor and instead chose the Ghurid amir Qutb al-Din Hasan b. 'Ali. Razia was deposed after she elevated Jamal-ud-Din Yaqut, her African slave, to the office of stable intendant. This ruffled the Turkish faction, especially angering the amir-hajib Ikhtiyar al-Din Aytegin. An attempted uprising in Lahore in 1239 by Kabir Khan did not succeed. Aytegin and his ally Altunia, the governor of Tabarhind, triggered a mutiny the following year while Razia was campaigning and killed Yaqut. Razia was imprisoned at Tabarhind where Altunia watched over her.
Muiz ud din Bahram was crowned as the next sultan. During his reign, the Turk amirs began strengthening their power; the new office of the na'ib was given to Aytegin. Moreover, the Bay'ah of the Turks was contingent on the designation of Aytegin as the na'ib. When Aytegin began encroaching on imperial powers, Bahram had him killed in 1240 during the month of Muharram. Another Shamsi, Badr al-Din Sonqur-i Rumi, who was the new amir-hajib, became influential. He was instrumental in the campaign against Altunia, who had married Razia and marched to Delhi to crown her after the death of Aytegin. The next highly influential figure was the new wazir, Muhadhdhab al-Din, who instigated the sultan against Sonqur after his relations with the latter soured. Sonqur was moving to crown one of Bahram's brothers, and the wazir reported this to Bahram. Sonqur was exiled from the royal court to his iqta'
In 1249, Balaban married his daughter to the sultan, was appointed the na'ib and allowed the title of Ulugh Khan. He transferred his rank of the amir-hajib to his brother Kishli Khan. Many of his supporters were elevated. Among them, the Shamsi Taj al-Din *Teniz Khan, said to be a loyal deputy of Balaban, was made the deputy amir-hajib. One of Balaban's slaves, Ikhtiyar al-Din Aytegin mui-yi daraz, who had previously been the deputy amir-i akhur, was appointed the chief amir-i akhur after Kishli Khan's promotion. At this point, according to Jackson, opponents of Balaban's faction had emerged within the Shamsi. Balaban and his group started making a coordinated assault on 'Izz al-Din Balaban, also known as Küshlu Khan. Küshlü Khan had lost Multan after it was conquered by Hasan of the Qarlughid dynasty. Multan was then occupied by Ulugh Khan's cousin Shir Khan, and Küshlü Khan did not succeed in his attempts to recapture the city. Ulugh Khan and the sultan expelled him from Nagaur, and the city was granted to Kishli Khan. Küshlü Khan then retreated to Uch, but he was imprisoned by Shir Khan and freed only after he had commanded the city's garrison to surrender. Küshlü Khan was then granted Budaun in early 1251.
Küshlü Khan avenged his mistreatment during 1252-1253. In the course of a campaign that year, Ulugh Khan was expelled to his iqta'
The rivals of Ulugh Khan were probably supported by the sultan and his mother; Rayhan was probably the slave of Mahmud Shah himself. Ulugh Khan's faction rose to power after it joined forces with the sultan's rebellious brother, Jalal al-Din Masud. Masud had left his iqta'
Ulugh Khan's long and mostly peaceful career had allowed him to gather resources, including his own personal troops. Ulugh Khan also had his own Turkish slaves, even before he had become the sultan. These included Amin Khan Aytegin Mui-yi Daraz, and the sipahsalar Qarachomaq. Ulugh Khan's enthronement is highly likely to have been supported by his old allies like Nusrat Khan Badr al-Din Sonqur and 'Imad al-Mulk, both of them were Shamsi and had supported Ulugh Khan during the brief siege of Delhi in 1257. Barani says Ulugh Khan, wanting to ruin his old Shamsi colleagues, had many of them poisoned.
Ulugh Khan's cousin Shir Khan, did not visit the imperial court during the reign of both Mahmud Shah and Ulugh Khan, afraid of also being poisoned. He was finally poisoned in 1269/1270 by Ulugh Khan. The Shamsi who escaped this elimination were excused only because they were favored by the sultan. Barani gives the names of two such Shamsi, Temür Khan and 'Adil Khan. Temür Khan Sonqur-i 'Ajami was the malik of Ghuram, and he received the iqta of Sunam and Samana after the death of Shir Khan. 'Adil Khan was the title of Sayf al-Din Aybeg Shamsi-yi 'Ajami. 'Imad al-Mulk, the maternal grandfather of Amir Khusrau, was also a Shamsi according to Barani. Nusrat Khan also continued to hold Bayana in 1271. However, Ulugh Khan's elimination of the Shamsi was not fully accomplished, as Barani says many sons of the Shamsi were officials during the reign of Ulugh Khan's family. Ulugh Khan has been accused of eliminating Turkish power in India by modern historians. Jackson says his eventual goal was to replace the Shamsi with his own slaves. Ulugh Khan may have intentionally supported the growing power of the Khalaj, who overthrew the Turkic power in the sultanate during the Khalji Revolution.
