In the dusty flood plain, 100,000 men and many times that in horses surround the walls of Baghdad. Catapults lob stones relentlessly into the city walls, hauled from great distance. Here, towers collapse under the barrage; there, ladders bring Mongol and subject peoples onto the fortifications, seizing them from the disorganized and panicking garrison. Arrows, some bearing messages, bring both confusion and injury where they land. The mighty Tigris River, the city's lifeblood, is now part of the trap; pontoon bridges, from them dangling nets embedded with iron hooks, rest both north and south of the city to catch those trying to flee. The final 'Abbasid Caliph sits frightened and overwhelmed in his palace, as the grasp of Hulegu Khan closes around him. Today, we discuss the fall of Baghdad, 1258.

And now, I'm your host David, and this is Kings and Generals: Ages of Conquest. We left our previous episode off with Hulegu destroying the Nizari Ismaili state, better known at the Order of Assassins, who had controlled a series of fortresses across eastern and northern Iran. By the end of 1256, Hulegu had reduced them to but a few holdouts, and he could begin to look to his next target. Considered heretics of the worst variety by most Sunni Muslims, the Persian writer Juvaini, a member of Hulegu's retinue, described his victory over the Nizaris in glowing terms, Hulegu as a sword of Islam carrying out God's will. Juvaini presents Hulegu's war as a more 'civilized' form of conquest compared to that of his grandfather, Chinggis Khan. Destruction was limited to Ismaili territories and the towns and fortresses that failed to submit, as opposed to the veritable tsunami of bloodshed Chinggis Khan wrought on the Khwarezmian empire over thirty years prior. What Hulegu was soon to do in Baghdad and to the titular head of Sunni Islam would not be so praised, and it is perhaps no coincidence that Juvaini's own chronicle ends with the fall of the Ismailis. As Hulegu left Ismaili territory in the final month of 1256, his eye was drawn to the 'Abbasid Caliph in Baghdad. In Islam, the spiritual leader of the religion was whoever was considered the successor to the Prophet Muhammad. For Shi'a Muslims, this was the imam- for Nizari Ismailis, the Imam was the ruler of Alamut, who had just been put to death on Mongol orders. For the majority of Muslims, known as Sunnis, the head of their faith was the Caliph, literally meaning 'successor.'The first four Caliphs to succeed the Prophet were the "Rightly Guided," the Rashidun, whose legitimacy is generally unquestioned by most Muslims. The Rashidun were succeeded by the Umayyads, who greatly extended Muslim rule east and west, across North Africa into Spain and across Eastern Iran into Central Asia. In 750, the Umayyad Caliphs were overthrown in the 'Abbasid revolution. Claiming descent from the Prophet's uncle 'Abbas, it was under the early 'Abbasids that the Caliphal capital was moved from Damascus to the newly established Baghdad along the Tigris River. Never comparable to the power of the Umayyads at their height, from the 9th century onwards the still vast 'Abbasid empire fragmented with threat from all directions: the Fatimids in Egypt, the Samanids, Buyids and Saffarids of Iran and finally from the steppes, the Great Seljuqs, all of which ground the 'Abbasids down until their state hardly stretched past the walls of Baghdad. The weakening of the Seljuqs after Sultan Malik-Shah's death in 1092 allowed the 'Abbasids to gradually reclaim independence and some authority, even repulsing a Seljuq army attacking Baghdad in 1157. The long reigns of Caliph al-Nasir and al-Mustansir, from 1180 until 1242, saw the 'Abbasids reclaim much of central and southern Iraq. A far cry from the sweeping power they had held in the 8th century, by the 13th century they still remained influential and held prestige. For 500 years they had been the heads of Islam, and had long cultivated an useful image as invioable and holy, above temporal affairs though they were more often than not mired in them. For instance, in the late 12th century Caliph al-Nasir was in conflict with the Seljuqs who continued to rule in Iran. He allied with the rising power northeast of the Iranian Seljuqs, the Khwarezmian Empire. Once vassals of the Great Seljuqs, the Khwarezm-shahs now butted heads with them as they expanded southwards, and the reigning Khwarezm-Shah, Tekesh bin Il-Arslan, was happy to ally himself with the Caliph. In 1194 at Rayy, modern Tehran, Tekesh defeated and killed the last Seljuq Sultan in Iran, Toghrul III, ending the dynasty and sending the Sultan's severed head to al-Nasir in Baghdad. Rather than provide freedom for the Caliphate, Tekesh now wanted to step into the place of Seljuqs. The Seljuqs' territory in Iran was largely annexed by Tekesh Khwarezm-shah, who soon began making aggressive motions to the Caliph. Al-Nasir encouraged the Khwarezmians' eastern neighbours, the Ghurids, in their war with Tekesh. Tekesh died in 1200, succeeded by his son Muhammad II as Khwarezm-shah who, through luck, timely assassinations and military victories, overcame the Ghurids, consolidated power over Iran and in 1217 tried to march on Baghdad itself. Muhammad's march on Baghdad was halted by a vicious snowstorm as he crossed the Zagros mountains, forcing him back. Returning to the northeast of his empire, Muhammad would there make the poor decisions which led to the Mongol Invasion of Khwarezm, covered way back in episode 9 of this podcast. Now, some authors of the period assert that Caliph al-Nasir actually invited Chinggis Khan to attack Muhammad of Khwarezm- when placed in the context of the Caliph switching to support whoever was on the eastern side of his current foe, there is definitely a logic to it. However, as we described in detail in episode 8 of the podcast, the cause of the Mongol invasion can be found in the foolery of Muhammad Khwarezm-shah alone. Had the Mongols come on the invitation of the Caliph, then surely they would have publicized that to justify the attack and sow further confusion among the Khwarezmians. In fact, in 1221 when detachments of Jebe and Subutai's army penetrated into northern Iraq, Caliph al-Nasir was hardly welcoming. Along with the rulers of northern Iraq's most important cities, Muzaffar ad-Din of Irbil and Badr al-Din Lu'lu', the de facto ruler of Mosul, the Caliph organized a short lived military coalition, which proved unnecessary as the Mongols soon withdrew. Evidently, the 'Abbasids spread a rumour that their army was absolutely gargantuan, their power unassailable and heavenly protected, and the Mongols were hesitant to commit. Had they paid close attention in the following years, they might have called the Caliph's bluff. In 1225 that favoured Khwarezmian rapscallion, Jalal al-Din Mingburnu, defeated a Caliphal army after the 'Abbasids failed to provide him assistance. Jalal al-Din chased the survivors right to the suburbs of Baghdad, then went north, defeated an army from Irbil sent to assist the Caliph and captured Irbil's ruler, Muzaffar ad-Din. Caliph al-Nasir, by then elderly, paralyzed and blind for three years, died soon after Jalal al-Din's attack, and was succeeded by his son, az-Zahir, as the 35th Caliph… for nine months. On Caliph az-Zahir's death in 1226, he was succeeded by his own son, al-Mustansir, the 36th and penultimate 'Abbasid Caliph of Baghdad. As Caliph, al-Mustanir continued to try to strengthen 'Abbasid control in Iraq and expand the army, but Mongol rule steadily spread over the region. By the start of the 1230s, Chormaqun Noyan and his lieutenants brought the submission of most of Iran and cast Mongol authority over the Caucasus. For Caliph al-Mustansir, the Mongol empire was a vast crescent to his north and east, where it stretched seemingly indefinitely. By 1235, Mongol forces mainly under Chagatai Noyan, "the Lesser," were probing northern Iraq and directly, but hesitantly, testing 'Abbasid hegemony in the region. In June 1237, Chagatai Noyan captured Irbil in what is now Iraqi Kurdistan, though the Citadel held out and in August Caliphal forces relieved the city. In February of 1238, an attack was launched on Baghdad, and a panicked Caliph al-Mustansir sent messages to the remaining independent Muslim powers from the Jazira and Syria down to Egypt for aid. Only 2,000 troops from the Ayyubid Sultan of Egypt, al-Kamil, reached Baghdad, and in June 1238 a caliphal army was defeated near the city. However, the defences of Baghdad itself remained formidable and the city stood defiant while the Mongols turned back from the walls, unprepared for both a long siege and or the fearsome Iraqi summer. Possibly, the Mongols suffered some sort of reverse while attacking Baghdad; some sixty years later, when the Persian historian Wassaf [vassaf] visited Baghdad, he recorded a Mongol defeat outside the walls, though this goes unmentioned by the other sources. While Baghdad remained independent, the Mongols continued to take cities in the region. Chormaqun's successor Baiju brought the submission of the Seljuqs of Anatolia in 1243; in 1244, the Mongol general Yasa'ur rode into Syria, dislodging the remnants of Jalal al-Din's Khwarezmians. The Ayyubids of Syria, the successors of the once mighty empire of Saladin Ayyubi, largely submitted over 1244-5, and even Antioch, one of the last of the Crusader Kingdoms, offered its submission. In late 1245 another attack on Baghdad was launched but soon aborted. The new Caliph since 1242, al-Mustasim ibn al-Mustansir, was lucky the attack was called off, for he was rather rapidly running out of allies. It seem that the new Caliph managed to avoid further attacks with a token submission: the Franscisan Friar John de Plano Carpini, present at the coronation of Guyuk Khaan in 1246, noted 'Abbasid envoys were present in Karakorum and believed they paid a regular tribute. The 38th and final 'Abbasid Caliph of Baghdad, al-Mustasim, was not the equal of his father or great-grandfather. While al-Nasir and al-Mustansir sought to strengthen the Caliphate, al-Mustasim was more interested in the luxury of Baghdad, and was nearly universally condemned for decadence. A great lover of music, he sponsored an entire neighbourhood in Baghdad to house musicians, including the most famous of the age, Saif al-Din Urmawi. A lover of pigeon racing, art, calligraphy and treasures, al-Mustasim was also indecisive and easily swayed by factions in his court, some of whom, such as the vizier, sought accomodation with the Mongols, while others urged to meet them in battle. As we will see shortly, the result was al-Mustasim vacillating in policy, wavering between antagonizing the Mongols and sending them gifts. Essentially, the worst sort of man to have in power when Hulegu marched on him with upwards of 100,000 men. Neither was weak leadership the only problem. Corruption and decadence of Baghdad's elite alienated the lower classes. A weak currency and high food prices contributed to revolts; many of Baghdad's soldiers increasingly found themselves unpaid and resorted to bandity or desertion. Topping off years of natural disasters- heavy rain, storms, annual flooding, in 1256, the Tigris, the river which runs through Baghdad, flooded for over a month, washing away much of Baghdad's lower city. Attributed to divine displeasure at the decadent al-Mustasim, for decades afterwards this flood was remembered as the "Mustasimid flood." As Mongol armies approached the city, pestilence killed many hundreds, if not thousands. The Caliph stood in a precarious position. Likely in late 1255, Hulegu sent a message to Caliph al-Mustasim demanding, as Hulegu had done with other rulers across the region, that Baghdad supply troops to help in the attack on the Nizari Isamilis. Al-Mustasim refused. As the 'Abbasids had been sending tribute in the previous years and were considered vassals, such a refusal was a declaration of independence. Hulegu, having been sent in part to find how sincere the Caliph's submission was, now had his casus belli, for to the Mongols, the Caliph of Baghdad was now in open revolt. War with the Caliph was not intended to punish Islam specifically; had the Mongols caught the Pope and considered him a rebel, certainly he would have shared a similar fate. What mattered to the Mongols was submission to their divinely mandated rule; refusal to submit was blasphemy of the highest order. After the fall of Alamut in December 1256, and spending some time near the still-resisting Nizari fortress of Lammasar, Hulegu stayed in Qazwin, just south of Alamut, until March 1257. From Qazwin he undertook a somewhat repetitive journey: from Qazwin he went to Hamadan, then to Dinavar, then Tabriz, then back to Hamadan, then back to Tabriz, then back to Hamadan in September 1257, from whence he would finally march on Baghdad. The reasons for this were multiple, and not just because Hulegu really liked northwestern Iran, though it did give him good time to evaluate the region. Firstly, Hulegu did not want to besiege Baghdad in the summer months, and instead needed to time the march so he arrived outside the city in the winter. Secondly, it provided time for his lieutenants to secure the neighbouring theaters: Kitbuqa Noyan secured through force and diplomacy Luristan and the passes through the Zagros mountains, ensuring Hulegu's main army could march unimpeded when the time came. In Anatolia, Baiju Noyan had needed to put down a Seljuq revolt, culminating in the battle of Aksaray in October 1256. Baiju then needed to move back east, in order to march on Baghdad from the west when the time came. Thirdly, Hulegu and the Caliph engaged in an entertaining round of diplomatic fisti-cuffs. Hulegu offered the Caliph another chance to surrender, repudiating him for his failure to send troops against the Nizaris. Hulegu's threat, as recorded by the Ilkhanid vizier Rashid al-Din, went as follows: "Previously we have given you advice, but now we say you should avoid our wrath and vengeance. Do not try to overreach yourself or accomplish the impossible, for you will only succeed in harming yourself. The past is over. Destroy your ramparts, fill in your moats, turn the kingdom over to your son, and come to us. If you do not wish to come, send all three, the vizier [al-Alqami], Sulaymanshah, and the Dawatdar, that they may convey our message word for word. If our command is obeyed, it will not be necessary for us to wreak vengeance, and you may retain your lands, army, and subjects. If you do not heed our advice and dispute with us, line up your soldiers and get ready for the field of battle, for we have our loins girded for battle with you and are standing at the ready. When I lead my troops in wrath against Baghdad, even if you hide in the sky or in the earth, 'I shall bring you down from the turning celestial sphere; I shall pull you up like a lion. I shall not leave one person alive in your realm, and I shall put your city and country to the torch.' "If you desire to have mercy on your ancient family's heads, heed my advice. If you do not, let us see what God's will is." The Caliph refused Hulegu's demands, and when he sent back Hulegu's envoys, they were harassed by the people of…
