Jalal ad-Din Khwârazmshâh

 

Jalal ad-Din Mingburnu (full name: Jalal ad-Dunya wa ad-Din Abul-Muzaffar Manguberdi ibn Muhammad), Manguberdi or Mangubarni (Turkic for "God-given"), also known as Jalâl ad-Dîn Khwârazmshâh , was the last ruler of the Turkic Khwarezmian Empire from the Anushtegin dynasty. He was the eldest son of Ala ad-Din Muhammad II by his Turkmen wife Aychichek.

Re-establishment of the kingdom

Jalal ad-Din Mingburnu spent three years in exile in India. He entered into an alliance with the Khokhars, Lahore, and much of the Punjab was captured. At this stage he requested an alliance with Iltutmish, the Turkish Mamluk Sultan of Delhi against the Mongols. The Sultan of Delhi refused so he could avoid a conflict with Genghis Khan and marched towards Lahore at the head of a large army. Mingburnu retreated from Lahore and moved towards Uchch, inflicting a heavy defeat on its ruler Nasir-ud-Din Qabacha, and plundered Sindh, then northern Gujarat before returning to Persia in 1224.

Having gathered an army and entered Persia, Jalal ad-Din sought to re-establish the Khwarazm kingdom, but he never fully consolidated his power. In 1224, he confirmed Burak Hadjib, ruler of the Qara Khitai, in Kerman, received the submission of his brother Ghiyath al-Din Pirshah, who had established himself in Hamadan and Isfahan, and the province of Fars, and clashed with the Caliph An Nasser in Khuzestan. In 1225, the sultan dethroned the Ildegizid Uzbek Muzaffar al-Din and set himself up in their capital of Tabriz on the 25 of July in 1225. In 1225, he attacked Georgia, defeating its forces in the battle of Garni, and conquered Tbilisi,after which allegedly a hundred thousand citizens were put to death for not renouncing Christianity.

Mongol invasion

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.

Death

Through the ruler of Alamut, the Mongols learned that Jalal ad-Din was weakened by a recent defeat. Ögedei Khan sent a new army of 30,000 men under the command of Chormagan and the Khwarazmians were swept away by the new Mongol army. In the winter of 1231, in the ensuing confusion the Mongols arrived into Azerbaijan from the direction of Khorasan and Rayy.  The 30,000 strong Mongol army led by Chormagan easily defeated Jalal ad-Din and occupied northern Iran. Khwarazmshah retreated to Ganja. The Mongols followed him and captured Arran. Jalal ad-Din took refuge in the Mayyafarikin mountains and there in August of that year he was killed by an unknown Kurd, allegedly employed by the Seljuks.
