After Alauddin's death, Mubarak Shah was imprisoned by Malik Kafur, who appointed his younger brother Shihabuddin Omar as a puppet monarch.
After ascending the throne, he resorted to populist measures, such as abolishing the heavy taxes and penalties imposed by his father, and releasing thousands of prisoners.
[10] He also made some new appointments: The paiks who had killed Malik Kafur claimed credit for putting Mubarak Shah on the throne, and demanded high positions in his court.
[11] To win popular support, Mubarak Shah revoked several of Alauddin's decisions: Before his death, Malik Kafur had conspired to kill Alp Khan, the governor of Gujarat.
[4] After ascending the throne, Mubarak Shah sent Malik Tughluq to Multani's camp, asking him to continue the march to Gujarat.
Therefore, he marched back to Delhi, and advised Mubarak Shah to send each officer a firman (letter of authority) and a khilat (robe of honour).
[16] In his second regnal year, Mubarak Shah executed Zafar Khan for unknown reasons, and appointed his homosexual partner Husamuddin as the governor of Gujarat.
After Husamuddin was deposed by the local amirs for apostacy, Mubarak Shah appointed Wahiduddin Quraishi as the new governor of Gujarat.
After Ayn al-Mulk Multani was sent to govern Devagiri, Quraishi was recalled to Delhi, and appointed wazir with the title Tajul Mulk.
Alauddin had decided against annexing the Deccan kingdoms to his empire, because of the difficulty of controlling and governing these distant territories remotely from Delhi.
[15] However, after the rebellion of the last Yadava tributary Bhillama, his general Malik Kafur had taken charge of Devagiri, and had received letters of submission from the various chiefs.
[18] Mubarak Shah wanted to recapture Devagiri immediately after his ascension, but his counsellors had advised him against attempting to do so without consolidating his rule in Delhi first.
[20] When the army reached Devagiri, all the local chiefs except Raghava and Harapaladeva accepted Mubarak Shah's suzerainty without offering any resistance.
The Delhi generals Khusrau Khan and Malik Qutlugh (who held the title amir-i shikar) led an army to pursue them.
[20] Khusrau Khan dispatched a force led by amir-i koh Malik Ikhtiyaruddin Talbagha (son of Yaghda) to pursue Harapaladeva, who was wounded and captured after 2-3 skirmishes.
The army was led by Khusrau Khan, Khwaja Haji (who had served as Alauddin's minister of war), and Malik Qutlugh (amir-i shikar).
[21] The Delhi army besieged the Kakatiya capital Warangal, and Prataparudra decided to negotiate truce after putting up some resistance.
Mubarak gave Hasan the title Khusrau Khan, several iqta, the army of the deceased Malik Kafur, and the wizarat.
[34] Khusrau Khan convinced Mubarak Shah to allow him to raise an army of Baradu Hindus by arguing that all other nobles (maliks) had their own groups of followers.
[37] Randhol, the maternal uncle of Khusrau Khan, entered the palace with a large number of Baradus, who hid daggers under their clothes.
When Ziyauddin let his guard down to accept a paan (betel leaf preparation) from Randhol, the Baradu leader Jaharya stabbed him to death.
However, Khusrau Khan told him that the royal horses had broken loose, and the noise was caused by the guards trying to catch the animals.
Meanwhile, Jaharya arrived at the scene, stuck a patta (axe) at the Sultan's chest, lifted him up by his hair, and threw him to the ground.
The royal guards fled to save their lives, as a large number of Baradus started massacring the palace residents.
Mubarak Shah then tried to prop up Shaikh Ruknuddin of Multan as a rival to Nizamuddin by declaring that he would personally consider all the petitions passed to him through the saint.
When Mubarak Shah constructed a jama masjid called Masjid-i-Miri and asked all Muslim scholars (ulama) and mystics to assemble there for the Friday prayers, Nizamuddin refused to oblige, declaring that he would visit the mosque closest to his home instead.
[41] Mubarak then declared that if Nizamuddin did not visit him personally at the beginning of the next lunar month, he would compel the saint to do so via an executive order.
