Hulagu Khan, also known as Hulagu, Hülegü or Hulegu (; Chaghatay/; Arabic:هولاكو; c. 1217 – 8 February 1265), was a Mongol ruler who conquered much of Southwest Asia. A grandson of Genghis Khan and the brother of Arik Boke, Mongke and Kublai Khan, he became the first khan of the Ilkhanate of Persia.

In 1255, Hulagu, the child of Tolui and Sorghaghtani Beki, a Christian woman, was sent by his brother Mongke (who was Great Khan from 1251-1258) to conquer or destroy the remaining Muslim states in southwestern Asia. His mother was a passionate Nestorian Christian, as was his wife, Dokuz Khatun, and his closest friend and general, Kitbuqa. Their influence was said to have instilled in him a deep animosity against Muslims — unusual for the generally tolerant Mongol Empire — along with a contrasting desire to assist Christians. He was also passionate about Persia and its culture, the reason why he became the Khan of Persia under Ilkhanate dynasty. The Persian influence was another factor that encouraged Hulagu to attack the Arabs. Hulagu always had many Persian chancellors, who wished to take revenge on the Arabs for their conquest of Persia centuries ago and also because Persia was a long time enemy of the Abassid caliphate. http://www.history.hacettepe.edu.tr/archive/oimakale.html

Hulagu's campaign sought the subjugation of the Lurs, a people of southern Iran; the destruction of the Hashshashin sect; the submission or destruction of the Abbasid caliphate; the submission or destruction of the Ayyubid states in Syria; and finally, the submission or destruction of the Bahri Mamluk Sultanate of Egypt. Mongke Khan ordered Hulagu to treat kindly those who submitted, and utterly destroy those who did not. History shows that Hulagu vigorously carried out the latter part of these instructions.

Hulagu told the Dominican missionary at his court David of Ashby that he had strong sympathies towards Christianity, through the influence of his Nestorian mother Sorghaghtani Beki, and that he was a Christian at heart. He also told the Armenian historian Vartan Arewelc'i in 1264 that he had been a Christian since birth. It is recorded however that he resorted to Buddhism as he neared his death, against the will of his Christian wife Dokuz Khatun.

Hulagu had at least three children: Abaqa, Ilkhan of Persia from 1265-1282, Taraqai, whose son Baidu became Ilkhan in 1295, and Teguder Ahmad, Ilkhan from 1282-1284.

Hulagu marched out with perhaps the largest Mongol army ever assembled. Among his subsidiary generals was Kitbuqa, a Christian. Hulagu easily destroyed the Lurs, and his reputation so frightened the Assassins (also known as the Hashshashin) that they surrendered their impregnable fortress of Alamut to him without a fight.

Hulagu probably always intended to take Baghdad, which the Mongols had been meaning to attack for over ten years (see Eljigidei), but he used the caliph's refusal to send troops to him as a pretext for conquest, since his brother the Great Khan had ordered him to be merciful to those who submitted. Hulagu sent a message to the caliph, Al-Musta'sim, containing the following (trans. John Woods):

:"When I lead my army against Baghdad in anger, whether you hide in heaven or in earth

:I will bring you down from the spinning spheres; :I will toss you in the air like a lion. :I will leave no one alive in your realm; :I will burn your city, your land, your self.

:If you wish to spare yourself and your venerable family, give heed to my advice with the ear of intelligence. If you do not, you will see what God has willed."

The Mongol army, led by Hulagu Khan set out for Baghdad in November of 1257. He marched with what was probably the largest army ever fielded by the Mongols. By order of Monke Khan, one in ten fighting men in the entire empire were gathered for Hulagu's army (Saunders 1971).

Hulagu demanded surrender; the caliph refused, warning the Mongols that they faced the wrath of God if they attacked the caliph. Many accounts say that the caliph failed to prepare for the onslaught; he neither gathered armies nor strengthened the walls of Baghdad. In fact, he had done the very worst things he could have done, he had angered Hulagu, given him an excuse to sack Bagdad, and done nothing to prevent the tragedy.

Once near the city, Hulagu divided his forces, so that they threatened both sides of the city, on the east and west banks of the Tigris. The caliph's army repulsed some of the forces attacking from the west, but were defeated in the next battle. The attacking Mongols broke some dikes and flooded the ground behind the caliph’s army, trapping them. Much of the army was slaughtered or drowned.

The Mongols under a Chinese general, Guo Kan, then laid siege to the city, constructing a palisade and ditch, wheeling up siege engines and catapults. The siege started on January 29. The battle was swift, by siege standards. By February 5 the Mongols controlled a stretch of the wall. Al-Musta'sim then tried to negotiate, but was refused.

On February 10 Baghdad surrendered. The Mongols swept into the city on February 13 and began a week of massacre, looting, rape, and destruction.

The Mongols proceded to sack Baghdad. The Grand Library of Baghdad, containing countless precious historical documents and books on subjects ranging from medicine to astronomy, was destroyed. Survivors said that the waters of the Tigris ran black with ink from the enormous quantities of books flung into the river. Citizens attempted to flee, but were intercepted by Mongol soldiers who raped and killed with abandon.

Although death counts vary widely and cannot be easily substantiated, a number of estimates do exist. Martin Sicker writes that close to 90,000 people may have died (Sicker 2000, p. 111). Other estimates go much higher. Muslim historian Abdullah Wassaf claims the loss of life was several hundred thousand or more. Ian Frazier of The New Yorker estimates of the death toll have ranged from 200,000 to a million. The Mongols looted and then destroyed. Mosques, palaces, libraries, hospitals — grand buildings that had been the work of generations were burned to the ground. The caliph was captured and forced to watch as his citizens were murdered and his treasury plundered. The caliph was trampled to death.

Marco Polo reports that Hulagu starved the caliph to death, but there is no corroborating evidence for that. Most historians believe the Mongol accounts (and Muslim) that the Mongols rolled the caliph up in a rug, and rode their horses over him, as they believed that the earth was offended if touched by royal blood. All of his sons but one were killed. Prior to this, the Mongols destroyed a city only if it had resisted them. Cities that capitulated at the first demand for surrender could usually expect to be spared. Cities that surrendered after a short fight, such as this, normally could expect a sack, but not complete devastation. The utter ferocity of the rape of Baghdad is one of the worst example of Mongol excess known. (It is said some Chinese cities suffered a similar fate, but this is not documented. Also, see Tamerlane, the conqueror of Mongol extraction and of Islamic and Turkic culture.)

Baghdad was a depopulated, ruined city for several centuries and only gradually recovered something of its former glory. Of all the Mongol Khans, Hulagu is, for obvious reasons, the most feared and despised.

Thus was the caliphate destroyed, and Mesopotamia ravaged; it has never again been such a major center of culture and influence. The smaller states in the region hastened to reassure Hulagu of their loyalty, and the Mongols turned to Syria in 1259, conquering the Ayyubids and sending advance patrols as far ahead as Gaza.

After Baghdad, in 1260, Mongol forces combined with Christians ones (the army of Cilician Armenia under Hetoum I, and the Franks of Bohemond VI) then conquered Muslim Syria, domain of the Ayyubid dynasty. They took together the city of Aleppo, and on March 1, 1260, the Mongols with the Armenians and the Franks of Antioch took Damascus, under the Christian Mongol general Kitbuqa. The three Christian rulers entered the city of Damascus together in triumph, and great Christian celebrations were made. Mass was celebrated in the Grand Mosque of the Umayyads (the former cathedral of Saint John the Baptist),, and numerous mosques were profanated:

This invasion effectively destroyed the Ayyubid Dynasty, theretofore powerful ruler of large parts of the Levant, Egypt and Arabia. The last Ayyubid king An-Nasir Yusuf was killed by Hulagu in 1260. With the Islamic power centers of Baghdad and Damascus gone, the center of Islamic power transferred to the Egyptian Mamluks in Cairo.

After the victory, Hulagu gave numerous gifts to Bohemond VI, including some of the conquered cities, including Lattakieh. But then because of a new internal conflict in Turkestan, Hulagu had to stop the Mongol invasion before it reached Egypt, and departed with the bulk of his forces, leaving only about 10,000 Mongol horsemen in Syria under Kitbuqa to occupy the conquered territory, including Nablus and Gaza in the south, as well as the fortress of Ajlun, east of River Jordan. The Mongols engaged in raids southward towards Egypt, reaching as far as Ascalon and Jerusalem, and a Mongol garrison of about 1,000 was placed in Gaza, with another garrison located in Naplouse. Runciman considers that Nablus and Gaza were occupied, but that Jerusalem itself was not reached by the Mongols. The Mongols however claimed repeatedly that they had remitted Jerusalem to the Christians on this occasion.

The death of Mongke forced Hulagu and most of his army to withdraw. The succession crisis that followed was the most ruinous to date. Indeed, although the succession was finally settled by imprisonment of one of his brothers, and another elevated to Great Khan, (Kublai Khan), the truth is that after 1258 there was no unified Mongol Empire, but four separate kingdoms, including the Il-Khanate of Persia established by Hulagu.

With Mongol territory now bordering the Franks, a few incidents occurred, one of them leading to large-scale trouble in Sidon. Julian de Grenier, Lord of Sidon and Beaufort, described by his contemporaries as irresponsible and light-headed, took the opportunity to raid and plunder the area of the Bekaa in Mongol territory. When the Mongol general Kitbuqa sent his nephew with a small force to obtain redress, they were ambushed and killed by Julian. Kitbuqa responded forcefully by raiding the city of Sidon, although the Castle of the city was left unattained. Another similar incident occurred when John II of Beirut and some Templars led a raid into Galilee. These events generated a significant level of distrust between the Mongols and the Crusader forces, whose own center of power was now in the coastal city of Acre. The incidents also raised the ire of the Mamluk leader Baibars. He declared that the treaty that had been signed between the Crusaders and the Mamluks in 1240 had been invalidated when Christian forces assisted the Mongols to capture Damascus. He demanded the evacuation of Saphet and Beaufort, and when the Christians balked, Baibars used that as his excuse to violate the pre-existing truce, and start launching new attacks on such settlements as Nazareth, Mount Tabor, and Bethlehem.

In the meantime, the Mongols led by Kitbuqa had fallen out with the crusaders holding the coast of Palestine, and the Mamluks were able to make a passive alliance with them, pass through their territory, and destroy the remnants of the Mongol army at Battle of Ain Jalut. Palestine and Syria were permanently lost, the border remaining the Tigris for the duration of Hulagu's dynasty.

Hulagu returned to his lands by 1262, after the succession was finally settled with Kublai as the last Great Khan, but instead of being able to avenge his defeats, was drawn into civil war with Batu Khan's brother Berke. Berke Khan, a Muslim convert, had promised retribution in his rage after Hulagu's sack of Baghdad, and allied himself with the Mamluks. Historian Rashid al-Din quoted Berke Khan as sending the following message to Mongke Khan, protesting the attack on Baghdad, (not knowing Mongke had died in China) "he has sacked all the cities of the Muslims, and has brought about the death of the Caliph. With the help of God I will call him to account for so much innocent blood." (see The Mongol Warlords, quoting Rashid al-Din's record of Berke Khan's pronouncement; this quote is also found in The Mamluk-Ilkhanid War).

On April 10, 1262, Hulagu sent through John the Hungarian a new letter to the French king Louis IX, offering again an alliance. The letter explained that two years before, in 1260, Hulagu had to withdraw the bulk of his army from Syria due to the hot weather and the lack of provisions and grass for the horses. The letter mentioned Hulagu's intention to capture Jerusalem for the benefit of the Pope, and asked for Louis to send a fleet against Egypt:

It is unclear whether the letter ever reached Louis IX in Paris, as the only known manuscript survived in Vienna, Austria.

Hulagu apparently sent an embassy to "all kings and princes overseas" in 1262 as well. The secretary Rychaldus accompanied the embassy, and made a report about it during the Second Council of Lyon in 1274. However the embassy was apparently intercepted in Sicily by King Manfred, who was allied with the Mamluks and in conflict with Pope Urban IV, and was returned by ship.

When Hulagu massed his armies to attack the Mamluks and avenge Ain Jalut, Berke Khan initiated a series of raids in force led by Nogai Khan which drew Hulagu north to meet him. Hulagu Khan suffered a severe defeat in an attempted invasion north of the Caucasus in 1263. This was the first open war between Mongols, and signaled the end of the unified empire.

Niccolò and Maffeo Polo travelled to the realm of Hulagu and stayed in the city of Bukhara, in modern day Uzbekistan, where the family lived and traded for three years from 1261 to 1264.

In 1264, Nicolò and Maffio joined up with an embassy sent by the Ilkhan Hulagu to his brother, the Grand Khan Kubilai. In 1266, they reached the seat of the Grand Khan in the Mongol capital Khanbaliq, present day Beijing, China.

Hulagu Khan died in 1265 and was buried in the Kaboudi Island in Lake Urmia. His funeral was the only Ilkhanid funeral to feature human sacrifice. He was succeeded by his son Abaqa, thus establishing his line.

The 13th century saw such a vogue of Mongol things in the West that many new-born children in Italy were named after Mongol rulers, including Hulagu: names such as Can Grande ("Great Khan"), Alaone (Hulagu), Argone (Arghun) or Cassano (Ghazan) are recorded.
