Khwarazmian sultan Jalal ad-Din conquers the Georgian capital of Tbilisi.

The Anushtegin dynasty or Anushteginids, also known as the Khwarazmian dynasty was a Sunni Muslim dynasty of Turkic mamluk origin from the Bekdili clan of the Oghuz Turks. The Anushteginid dynasty ruled the Khwarazmian Empire, consisting in large parts of present-day Central Asia, Afghanistan and Iran in the approximate period of 1077 to 1231, first as vassals of the Seljuks and the Qara Khitai, and later as independent rulers, up until the Mongol conquest of the Khwarazmian Empire in the 13th century.

Sultan is a position with several historical meanings. Originally, it was an Arabic abstract noun meaning "strength", "authority", "rulership", derived from the verbal noun سلطة sulṭah, meaning "authority" or "power". Later, it came to be used as the title of certain rulers who claimed almost full sovereignty without claiming the overall caliphate, or to refer to a powerful governor of a province within the caliphate. The adjectival form of the word is "sultanic", and the state and territories ruled by a sultan, as well as his office, are referred to as a sultanate.

Jalal al-Din Mangburni, also known as Jalal al-Din Khwarazmshah, was the last Khwarazmshah of the Anushtegin 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.
