context_page_description: Jalal ad-Din Mingburnu, Manguberdi or Mangubarni, also known as Jalâl ad-Dîn Khwârazmshâh, was the last ruler of the Khwarezmian Empire from the Anushtegin dynasty. He was the eldest son of Ala ad-Din Muhammad II by his Turkmen wife Aychichek.
context_section_description: When it became known that Genghis Khan was marching towards Khwarazm, Jalal ad-din proposed to his father to meet the Mongols in one decisive battle near the Syr Darya. However, Muhammad II relied on his well-fortified fortresses and did not assemble troops, distributing them instead among the major towns of his empire. Meanwhile, the Mongols swiftly took one city after another. At the beginning of 1220, Bukhara fell, followed by Samarqand. Muhammad started to retreat west, and after a series of unsuccessful battles, was left with a handful of soldiers and his sons. The huge and undisciplined Khwarazmian army was unable to defeat the enemy, which was much inferior in number. 
  Legend has it that Muhammad, who fled to the Caspian Sea, being terminally ill, gathered his sons: Jalal ad-Din, Aqshah, and Uzlagh Khan and announced that he appointed Jalal ad-Din as heir to the throne, because only he could confront the enemy. Summoning the younger sons to obedience, he hung his sword on the belt of Jalal ad-Din. A few days later, Muhammad died and Jalal ad-Din was proclaimed a Khwarazmshah. 
  Following the defeat of his father, Ala ad-Din Muhammad II by Genghis Khan in 1220, Jalal ad-Din Mingburnu came to power and 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 slaughtered 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. The cities of Herat, Ghazni and Merv were destroyed and massacred by the Mongols, for his resistance or rebelliousness.
