Jalal ad-Din Mingburnu

Jalal ad-Din Mingburnu (Persian: جلال ‌الدین خوارزمشاه; full name: Jalal ad-Dunya wa ad-Din Abul-Muzaffar Manguberdi ibn Muhammad) or Manguberdi (Turkic for "Godgiven"), also known as Jalâl ad-Dîn Khwârazmshâh, was the last ruler of the Khwarezmian Empire. Following the defeat of his father, Ala ad-Din Muhammad II by Genghis Khan in 1220, Jalal ad-Din Mengübirti came to power but he rejected the title shah that his father had assumed and called himself simply sultan. Jalal ad-Din retreated with the remaining Khwarazm forces, while pursued by a Mongol army and at the battle of Parwan, north of Kabul, defeated the Mongols.

Due to the Mongol invasion, the sacking of Samarkand and being deserted by his Afghan allies, Jalal ad-Din was forced to flee to India. At the Indus River, however, the Mongols caught up with him and killed his forces along with thousands of refugees at the Battle of Indus. He escaped and sought asylum in the Sultanate of Delhi but Iltutmish denied this to him in deference to the relationship with the Abbasid caliphs.
