Ruknuddin Firuz

Rukn-ud-din Firuz (Persian: رکن‌الدین فیروز), also transliterated as Rukn al-Din Firoz (1211 – 19 November 1236), was a ruler of Delhi sultanate for less than seven months in 1236.

[2][3] He administered Badaun with the support of Ainul Mulk Husain Ash'ari, a former minister of Iltutmish's rival Nasir ad-Din Qabacha.

[3] 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.

[9] While spending his time and the state funds in pursuing pleasure, Ruknuddin left the control of administration to his mother Shah Turkan.

[1] Shah Turkan was originally reputed for charitable and religious donations, but her nature changed after she gained control of the administration.

Ruknuddin marched back to Delhi, but Razia sent a force to arrest him: he was imprisoned and probably executed on 19 November 1236, having ruled for 6 months and 28 days.
