After the death of his father Iltutmish, Ruknuddin ascended the throne in April–May 1236. Saifuddin Hasan
Qarlugh, who assumed that the Delhi Sultanate would be weakened after Iltutmish's death, invaded India around this time. However, Saifuddin Aibak - a Turkic slave officer appointed as the governor of
Uch by Iltutmish, defeated him and forced him to retreat. The historian Minhaj-i-Siraj praises Ruknuddin for three qualities: handsomeness, gentle temperament, and generous nature. According to Minhaj, Ruknuddin greatly enjoyed riding elephants, and greatly favoured
mahouts, who became important in his court. Minhaj narrates that Ruknuddin would scatter gold coins in
bazaars, while riding intoxicated on an elephant. He used to spend a lot of money on musicians, clowns, and eunuchs. While spending his time and the state funds in pursuing pleasure, Ruknuddin left the control of administration to his mother Shah Turkan.
Rebellions Shah Turkan was originally reputed for charitable and religious donations, but her nature changed after she gained control of the administration. She mistreated ladies in Iltutmish's harem, and according to Minhaj, "destroyed" several of them. She and Ruknuddin ordered the blinding and killing of Qutubuddin, a young and popular son of Iltutmish, which triggered several rebellions: • In the
Awadh region, Malik Ghiyasuddin Muhammad Shah - a son of Iltutmish - rebelled against Ruknuddin. He sacked several towns, and plundered the treasure of Lakhnauti, which was being transferred to Delhi. • Malik Izzuddin Muhammad Salari, who now held the
iqta' of Badaun, also rebelled. • Three other iqta-holding nobles collectively rebelled against Ruknuddin: Malik Izzuddin Kabir Khan Ayaz (
Multan), Malik Saifuddin Kuchi (
Hansi), Malik Alauddin Jani (
Lahore). Ruknuddin sent an army against the rebels, but his
wazir (prime minister)
Nizamul Mulk Junaidi deserted the army at Kailugarhi, and fled to
Koil (modern Aligarh), later joining Salari. The forces of Junaidi and Salari subsequently joined the forces of Kuchi and Jani.
Massacre of Tazik officers The officers of Ruknuddin's father Iltutmish belonged to two major categories: the Turkic-origin slaves and the
Tazik-origin non-slaves. The Tazik officers included the prime minister Junaidi. After the rebellions against Ruknuddin, the Turkic officers, who formed the core of Ruknuddin's army, planned murders of many Tazik officers in the
Mansurpur-
Tarain region. Several important Tazik officers were killed as a result: • Tajul Mulk Mahmud,
dabir • the son of
mushrif-i mamalik • Bahauddin Hasan Ash'ari • Karimuddin Zahid • Ziyal Mulk, the son of Junaidi • Nizamuddin Shafurqani • Khwaja Rashiduddin Malikani • Amir Fakhruddin,
dabir • Bahram Shah,
