Jalal al-Din Mangburni
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.
The new Shah Jalal al-Din moved to Gurganj, but departed eastwards after Terken Khatun moved against him; evading Mongol patrols, he gathered a substantial army at Ghazni. He managed to inflict an excellent defeat on Shigi Qutuqu at the Battle of Parwan, but soon lost a good portion of his army in a dispute over spoils. He was defeated by a vengeful Genghis Khan at the Battle of the Indus, and fled across the river. Now essentially a warlord, Jalal al-Din managed to establish a succession of short-lived states: first in the Punjab from 1222 to 1224, and then in northwest Iran and Georgia after 1225. Jalal al-Din did not have the political ability needed to underpin his martial exploits, and he was forced to combat several large revolts and increasing pressure from Mongol forces. Eventually, he was killed in 15 August 1231. The army he had gathered would continue to terrorize the Levant as the mercenary Khwarazmiyya until its final defeat in 1246.
Name and early life
The spelling and meaning of his Turkic personal name is obscure. In al-Nasawi's work his name was written as "Jalal al-Din Mankubirti, son of the Sultan Muhammad, son of Tekish, son of Il-Arslan, son of Atsiz, son of Muhammad, son of Nushtekin". Original publisher of the manuscript,, rendered his name as "Mankobirti" and translated it as "Dieu donné". Due to Arabic rendering, early scholarship spelled it as Manguburti, whilst the most common variant today is Mangburni or Mingirini.Jalal al-Din was reportedly the eldest son of the Khwarazmshah Ala ad-Din Muhammad II, while his mother was a concubine of Turkmen origin, whose name was Ay-Chichek. Due to the low status of Jalal al-Din's mother, his powerful grandmother and Kipchak princess Terken Khatun refused to support him as heir to the throne, and instead favored his half-brother Uzlagh-Shah, whose mother was also a Qipchaq. Jalal al-Din first appears in historical records in 1215, when Muhammad II divided his empire among his sons, giving the southwestern part to Jalal al-Din.
Mongol campaigns
Mongol invasion and accession
had chosen to ignore a skirmish between his son Jochi Khan and the Shah, in which Jalal al-Din's military acumen had saved the Shah from a humiliating defeat. However, he could not ignore the seizure of a trade caravan in Otrar and subsequent execution of Mongol envoys in Gurganj. War between the two new neighbours was inevitable. The Khan commanded a skilled and disciplined army: the precise size of it is disputed, but most agree on around 75,000 to 200,000 soldiers. The Khwarazmshah, meanwhile, faced many problems. His empire was vast and newly formed, with a still-developing administration. In addition, his mother Terken Khatun still wielded substantial power in the realm – one historian termed the relationship between the Shah and his mother as 'an uneasy diarchy', which often acted to Muhammad's disadvantage. The Shah also distrusted most of his commanders, with the only exception being Jalal al-Din. If he had sought open battle, as many of his commanders wished, he would certainly have been greatly outmatched in quantity of troops, let alone quality. The Shah thus made the decision to distribute his forces as garrison troops inside his most important towns, such as Samarkand, Merv and Nishapur. Meanwhile, the Shah raised taxes to raise a field army, with whom he would harass the besieging Mongol forces.However, through a combination of excellent manoeuvering and planning, the Mongols managed to carve a path of destruction through Khwarazmia. Otrar fell, and Bukhara was taken, as was Samarkand. Genghis Khan then sent an army under his elite generals Jebe and Subutai specifically to pursue the Shah; although Muhammad, accompanied by Jalal-al Din and two other sons, managed to escape, he was prevented from gathering any forces as his empire collapsed around him. Fleeing to the loyal region of Khorasan, the Shah died destitute on an island in the Caspian Sea. Jalal al-Din would later claim that his father had appointed him as his successor on his deathbed. Meanwhile, the Mongols had occupied all of Transoxania, and had invaded Tocharistan, Guzgan and Gharchistan during the latter half of 1220.
Jalal al-Din rode to Gurganj, a city reportedly housing 90,000 soldiers, and found the city in turmoil. The city's nobility, like Terken Khatun, were not prepared to accept Jalal al-Din as Shah, preferring the more malleable Uzlaq, and planned a coup against Jalal al-Din.Jalal Al-Din left the capital after being warned of the coup, accompanied by Timur Malik and 300 cavalry. Crossing the Karakum Desert, he attacked the garrison of a Mongol detachment at Nesa, killing most of the force including two brothers of Toghachar, son in law of Genghis Khan. The Mongols pursued, past Nishapur and Herat, but lost the trail before Ghazni, where Jalal al-Din found 50,000 loyalists waiting for him. After a few days, he was joined by his maternal uncle Temur Malik, who brought an additional 30,000 veterans – Jalal al-Din now had a sizeable force with which to strike back at the Mongols. Meanwhile, back in Khwarazm, Gurganj, Merv, Balkh, and Nishapur had all been taken by the Mongol forces.
Battles at Parwan and the Indus
Jalal al-Din, who had just married Temur Malik's daughter to solidify ties, marched towards Kandahar which was under siege by a Mongol army and defeated them after a two-day battle. In autumn 1221, he then moved north to Parwan and attacked a besieging army north of Charikar in the Battle of Waliyan; the numerically inferior Mongols lost 1,000 and retreated across the river, destroying the bridge. Genghis sent an army numbering between thirty and forty-five thousand under Shigi Qutuqu to confront the Shah. The Battle of Parwan was fought on a rock-strewn, narrow valley which was unsuitable for the Mongol cavalry, and the Muslims fought dismounted until the final charge led by Jalal al-Din, who personally commanded the center, resulting in the repulsion of the Mongols. This battle made Jalal al-Din's reputation; however, he soon lost half of his army through infighting: the sources report a dispute over booty between Temur Malik and Ighrak, commander of the right flank.Jalal al-Din had won several victories against the Mongols in 1221, and after the Battle of Parwan, independent insurgency groups emerged in multiple cities inspired by his deeds. Kushteghin Pahlawan launched a revolt in Merv and ousted the Mongol administration; he then made a successful attack on Bukhara, while Herat also rebelled. These revolts would be crushed by the Mongols, and many atrocities perpetuated as retribution.
Genghis Khan, now at Bamiyan, did not take this defeat lightly. After executing that fortress, he made his way eastwards to confront Jalal al-Din, using his powers of organisation to send detachments out to prevent the disparate Khwarazmid factions from uniting, one of whom al-Din managed to isolate and defeat. Jalal Al-Din knew he had no chance of winning against Genghis in a pitched battle with his diminished army and after attempts to win back Ighrak and his men failed, he marched towards India. The Khan's army managed to surround Jalal al-Din's army on the banks of the River Indus and crushed them in the ensuing battle in November 1221. The Shah escaped the battle by jumping into the river fully armed, and reaching the other shore. This act of desperation is said to have drawn the admiration of Genghis Khan, who forbade Mongols to pursue the Shah or shoot him with arrows. The Shah's surviving troops were however slaughtered, along with his harem and children.
Later campaigns
Indian subcontinent
After the Battle of the Indus, Jalal al-Din crossed the Indus and settled in India. A local prince, who had six thousand men attacked Jalal al-Din's makeshift forces of no more than four thousand, but al-Din still triumphed, greatly enhancing his Indian appeal. He then sought asylum in the Sultanate of Delhi but Iltutmish denied this to him because of al-Din's poor relationship with the Abbasid caliphs; he did however give one of his daughters to al-Din as a peace offering. The Khan sent Dorbei Doqshin with two tumens to pursue al-Din, whom he still regarded as a threat, in early 1222; one account has Doqshin fail to secure al-Din, and return to the Khan in Samarkand, who was so infuriated Doqshin was sent out at once on the same task. Meanwhile, al-Din was quarrelling with local princes, but was mostly victorious when it came to battle.Under Doqshin's leadership, the Mongol army took Nandana fort of Janjua tribe from one of the lieutenants of Jalal al-Din, sacked it, then proceeded to besiege the larger Multan. The Mongol army managed to breach the wall but the city was defended successfully by the Khwarazmians; due to the hot weather, the Mongols were forced to retreat after 42 days. Peter Jackson suggests that Doqshin, having been instructed not to return unsuccessfully, eventually converted to Islam and joined al-Din. The rest of al-Din's three years in exile in India were spent in taking large parts of Lahore and the Punjab; he returned to Persia at the behest of his brother Ghiyath al-Din Pirshah, who still controlled parts of Persia, in late 1223.
