by Something Something

The Ilkhanate, also spelled Il-khanate was a khanate established from the southwestern sector of the Mongol Empire. The Ilkhanid realm was ruled by the Mongol House of Hulagu. Hulagu Khan, the son of Tolui and grandson of Genghis Khan, inherited the Middle Eastern part of the Mongol Empire after his brother Möngke Khan died in 1260.

Its core territory lies in what is now part of the countries of Iran, Azerbaijan, and Turkey. At its greatest extent, the Ilkhanate also included parts of modern Iraq, Syria, Armenia, Georgia, Afghanistan, Turkmenistan, Pakistan, part of modern Dagestan, and part of modern Tajikistan. Later Ilkhanate rulers, beginning with Ghazan in 1295, converted to Islam. In the 1330s, the Ilkhanate was ravaged by the Black Death. Its last khan Abu Sa'id died in 1335, after which the khanate disintegrated.

Konye-Urgench, Turkmenistan

When Muhammad II of Khwarazm executed a contingent of merchants dispatched by the Mongols, Genghis Khan declared war on the Khwārazm-Shāh dynasty in 1219. The Mongols overran the empire, occupying the major cities and population centers between 1219 and 1221. Iran was ravaged by the Mongol detachment under Jebe and Subutai, who left the area in ruin. Transoxiana also came under Mongol control after the invasion.

Muhammad's son Jalal ad-Din Mingburnu returned to Iran in c. 1224 after fleeing to India. He was overwhelmed and crushed by Chormaqan's army sent by the Great Khan Ögedei in 1231. By 1237 the Mongol Empire had subjugated most of Persia, Azerbaijan, Armenia, most of Georgia, as well as all of Afghanistan and Kashmir. After the battle of Köse Dağ in 1243, the Mongols under Baiju occupied Anatolia, while the Seljuk Sultanate of Rûm and the Empire of Trebizond became vassals of the Mongols.

In 1252, Hulagu was tasked with conquering the Abbasid Caliphate. He was given a fifth of the entire Mongol army for the campaign and he took his sons Abaqa and Yoshmut along with him. In 1258, Hulagu proclaimed himself Ilkhan (subordinate khan).

Mongol campaign against the Nizaris

1253 Jan 1 -

Alamut, Qazvin Province, Ira

The Mongol campaign against the Nizaris of the Alamut period (the Assassins) began in 1253 after the Mongol conquest of the Khwarazmian Empire of Iran by the Mongol Empire and a series of Nizari–Mongol conflicts. The campaign was ordered by the Great Khan Möngke and was led by his brother, Hülegü. The campaign against the Nizaris and later the Abbasid Caliphate was intended to establish a new khanate in the region—the Ilkhanate.

Hülegü's campaign began with attacks on strongholds in Quhistan and Qumis amidst intensified internal dissensions among Nizari leaders under Imam Ala al-Din Muhammad whose policy was fighting against the Mongols.

In 1256, the Imam capitulated while besieged in Maymun-Diz and ordered his followers to do likewise according to his agreement with Hülegü. Despite being difficult to capture, Alamut ceased hostilities too and was dismantled. The Nizari state was thus disestablished, although several individual forts, notably Lambsar, Gerdkuh, and those in Syria continued to resist. Möngke Khan later ordered a general massacre of all Nizaris, including Khurshah and his family. Many of the surviving Nizaris scattered throughout Western, Central, and South Asia.

Siege of Gerdkuh Castle

1253 May 1 -

Gerdkuh, Gilan Province, Ira

In March 1253, Hülegü's commander Kitbuqa, who was commanding the advance guard, crossed Oxus (Amu Darya) with 12,000 men (one tümen plus two mingghans under Köke Ilgei). In April 1253, he captured several Nizari fortresses in Quhistan and killed their inhabitants, and in May he attacked Qumis and laid siege to Gerdkuh with 5,000 men and build walls and siege works around it. Kitbuqa left an army under amir Büri to besiege Gerdkuh.

In December 1253, Girdkuh's garrison sallied at night and killed 100 (or several hundred) Mongols, including Büri. In the summer of 1254, an outbreak of cholera in Gerdkuh weakened the garrison's resistance. However, unlike Lambsar, Gerdkuh survived the epidemic and was saved by the arrival of reinforcements from Ala al-Din Muhammad in Alamut.

As Hülegü's main army was advancing in Iran, Khurshah ordered Gerdkuh and fortresses of Quhistan to surrender. The Nizari chief in Gerdkuh, Qadi Tajuddin Mardanshah, surrendered, but the garrison continued to resist. In 1256, Maymun-Diz and Alamut surrendered and were destroyed by the Mongols, resulting in the official disestablishment of the Nizari Ismaili state.


Siege of Maymun-Diz

1256 Nov 8 -

Meymoon Dej, Shams Kelayeh,

The siege of Maymun-Diz, an unlocated fortress and the stronghold of the leader of the Nizari Ismaili state, Imam Rukn al-Din Khurshah, occurred in 1256, during the Mongol campaign against the Nizaris led by Hülegü. The new Nizari Imam was already engaged in negotiations with Hülegü as he was advancing toward his stronghold. The Mongols insisted that all Nizari fortresses be dismantled, but the Imam tried to negotiate a compromise.

After several days of fighting, the Imam and his family capitulated and were received well by Hülegü. Maymun-Diz was demolished, and the Imam ordered his subordinates to surrender and demolish their fortresses likewise. The subsequent capitulation of the symbolic stronghold of Alamut marked the end of the Nizari state in Persia.

Siege of Baghdad

1258 Jan 29 -

Baghdad, Iraq

The Siege of Baghdad was a siege that took place in Baghdad in 1258, lasting for 13 days from January 29, 1258 until February 10, 1258. The siege, laid by Ilkhanate Mongol forces and allied troops, involved the investment, capture, and sack of Baghdad, which was the capital of the Abbasid Caliphate at that time.

The Mongols were under the command of Hulagu Khan, brother of the khagan Möngke Khan, who had intended to further extend his rule into Mesopotamia but not to directly overthrow the Caliphate. Möngke, however, had instructed Hulagu to attack Baghdad if the Caliph Al-Musta'sim refused Mongol demands for his continued submission to the khagan and the payment of tribute in the form of military support for Mongol forces in Persia.

Hulagu subsequently besieged the city, which surrendered after 12 days.During the next week, the Mongols sacked Baghdad, committing numerous atrocities. The Mongols executed Al-Musta'sim and massacred many residents of the city, which was left greatly depopulated. The siege is considered to mark the end of the Islamic Golden Age, during which the caliphs had extended their rule from the Iberian Peninsula to Sindh, and which was also marked by many cultural achievements in diverse fields.

Toluid Civil War

1260 Jan 1 -


The Toluid Civil War was a war of succession fought between Kublai Khan and his younger brother, Ariq Böke, from 1260 to 1264. Möngke Khan died in 1259 with no declared successor, precipitating infighting between members of the Tolui family line for the title of Great Khan that escalated to a civil war. The Toluid Civil War, and the wars that followed it (such as the Berke–Hulagu war and the Kaidu–Kublai war), weakened the authority of the Great Khan over the Mongol Empire and split the empire into autonomous khanates.

Battle of Ain Jalut

1260 Sep 3 -

ʿAyn Jālūt, Israel

The Battle of Ain Jalut was fought between the Bahri Mamluks of Egypt and the Mongol Empire in southeastern Galilee in the Jezreel Valley near what is known today as the Spring of Harod. The battle marked the height of the extent of Mongol conquests, and was the first time a Mongol advance was permanently beaten back in direct combat on the battlefield.

Shortly after this, Hulagu returned to Mongolia with the bulk of his army in accordance with Mongol customs, leaving approximately 10,000 troops west of the Euphrates under the command of general Kitbuqa. Learning of these developments, Qutuz quickly advanced his army from Cairo towards Palestine. Kitbuqa sacked Sidon, before turning his army south towards the Spring of Harod to meet Qutuz' forces. Using hit-and-run tactics and a feigned retreat by Mamluk general Baibars, combined with a final flanking maneuver by Qutuz, the Mongol army was pushed in a retreat toward Bisan, after which the Mamluks led a final counterattack, which resulted in the death of several Mongol troops, along with Kitbuqa himself.

First Battle of Homs

1260 Dec 10 -

Homs‎, Syria

The first Battle of Homs was fought between the Ilkhanates of Persia and the forces of Egypt. After the historic Mamluk victory over the Ilkhanates at the Battle of Ain Jalut in September 1260, Hulagu Khan of the Ilkhanate had the Ayyubid Sultan of Damascus and other Ayyubid princes executed in revenge, thus effectively ending the dynasty in Syria. However, the defeat at Ain Jalut forced the Ilkhanate armies out of Syria and the Levant. The main cities of Syria, Aleppo and Damascus were thus left open to Mamluk occupation. But Homs and Hama remained in the possession of minor Ayyubid princes. These princes, rather than the Mamluks of Cairo themselves, actually fought and won the First Battle of Homs.

Due to the open war between Hulagu and his cousin Berke of the Golden Horde during the civil war of the Mongol Empire, the Ilkhanate could only afford to send 6,000 troops back into Syria to retake control of the lands. This expedition was initiated by Ilkhanate generals such as Baidu who was forced to leave Gaza when the Mamluks advanced just before the battle of Ain Jalut. After attacking Aleppo, the force travelled southwards to Homs, but were decisively defeated. This ended the first campaign into Syria by the Ilkhanate.

Berke–Hulagu War

1262 Jan 1 -

Caucasus Mountains

The Berke–Hulagu war was fought between two Mongol leaders, Berke Khan of the Golden Horde and Hulagu Khan of the Ilkhanate. It was fought mostly in the Caucasus mountains area in the 1260s after the destruction of Baghdad in 1258. The war overlaps with the Toluid Civil War in the Mongol Empire between two members of the Tolui family line, Kublai Khan and Ariq Böke, who both claimed the title of Great Khan (Khagan). Kublai allied with Hulagu, while Ariq Böke sided with Berke. Hulagu headed to Mongolia for the election of a new Khagan to succeed Möngke Khan, but the loss of the Battle of Ain Jalut to the Mamluks forced him to withdraw back to the Middle East. The Mamluk victory emboldened Berke to invade the Ilkhanate. The Berke–Hulagu war and the Toluid Civil War as well as the subsequent Kaidu–Kublai war marked a key moment in the fragmentation of the Mongol empire after the death of Möngke, the fourth Great Khan of the Mongol Empire.

Reign and Death of Arghun

1282 Jan 1 -

Tabriz, East Azerbaijan Prov

Abaqa's death in 1282 triggered a succession struggle between his son Arghun, supported by the Qara'unas, and his brother Tekuder, supported by the Chinggisid aristocracy. Tekuder was elected khan by the Chinggisids. Tekuder was the first Muslim ruler of the Ilkhanate but he made no active attempt to proselytize or convert his realm. However he did try to replace Mongol political traditions with Islamic ones, resulting in a loss of support from the army. Arghun used his religion against him by appealing to non-Muslims for support. When Tekuder realized this, he executed several of Arghun's supporters, and captured Arghun. Tekuder's foster son, Buaq, freed Arghun and overthrew Tekuder. Arghun was confirmed as Ilkhan by Kublai Khan in February 1286.

During Arghun's reign, he actively sought to combat Muslim influence, and fought against both the Mamluks and the Muslim Mongol emir Nawruz in Khorasan. To fund his campaigns, Arghun allowed his viziers Buqa and Sa'd-ud-dawla to centralize expenditures, but this was highly unpopular and caused his former supporters to turn against him. Both viziers were killed and Arghun was murdered in 1291.


Decline of the Ilkhanate

1295 Jan 1 -

Tabriz, East Azerbaijan Prov

The Ilkhanate started crumbling under the reign of Arghun's brother, Gaykhatu. The majority of Mongols converted to Islam while the Mongol court remained Buddhist. Gaykhatu had to buy the support of his followers and as a result, ruined the realm's finances. His vizir Sadr-ud-Din Zanjani tried to bolster the state finances by adopting paper money from the Yuan dynasty, which ended horribly. Gaykhatu also alienated the Mongol old guard with his alleged sexual relations with a boy. Gaykhatu was overthrown in 1295 and replaced with his cousin Baydu. Baydu reigned for less than a year before he was overthrown by Gaykhatu's son, Ghazan.


Ilkhan Ghazan converts to Islam

1297 Jan 1 -

Tabriz, East Azerbaijan Prov

Ghazan converted to Islam under influence of Nawrūz and made Islam the official state religion. Christian and Jewish subjects lost their equal status and had to pay the jizya protection tax. Ghazan gave Buddhists the starker choice of conversion or expulsion and ordered their temples to be destroyed; though he later relaxed this severity. After Nawrūz was deposed and killed in 1297, Ghazan made religious intolerance punishable and attempted to restore relations with non-Muslims.

Ghazan also pursued diplomatic contacts with Europe, continuing his predecessors' unsuccessful attempts at forming a;Franco-Mongol alliance. A man of high culture, Ghazan spoke multiple languages, had many hobbies, and reformed many elements of the Ilkhanate, especially in the matter of standardizing currency and fiscal policy.
