Jalal al-Din Mangburni

Jalal al-Din Mangburni (Persian: جلال الدین مِنکُبِرنی), also known as Jalal al-Din Khwarazmshah (جلال الدین خوارزمشاه), was the last Khwarazmshah of the Anushteginid dynasty. The eldest son and successor of Ala ad-Din Muhammad II of the Khwarazmian Empire, Jalal al-Din was brought up at Gurganj, the wealthy capital of the Khwarazmid homeland. An able general, he served as second-in-command to his father in at least one battle; however, since he was the son of a concubine, he was challenged as successor by a younger brother, whose cause was supported by the powerful Queen Mother, Terken Khatun. Nevertheless, after the Mongol conquest of the Khwarazmian Empire led to his father's flight and death on an island in the Caspian Sea, Jalal-al Din gained the loyalty of the majority of Khwarazmian loyalists.
