, and the Mamluks in Cairo responded by arresting the emirs who were loyal to the Ayyubids in Egypt. In addition to the Ayyubids in Syria, the Abbasid caliph al-Musta'sim in Baghdad also rejected the Mamluk move in Egypt and refused to recognize Shajar al-Dur as a sultan. The refusal of the Caliph to recognize Shajar al-Durr as the new sultan was a great setback to the Mamluks in Egypt, as the custom during the Ayyubid era was that the Sultan could gain legitimacy only through the recognition of the Abbasid caliph.
[Shayyal, p. 115, vol. 2] The Mamluks, therefore, decided to install Izz al-Din Aybak as a new sultan. He married Shajar al-Durr, who abdicated and passed the throne to him after she had ruled Egypt as sultan for about three months. Though the period of Shajar al-Durr's rule as a sultan was of short duration, it witnessed two important events in history: the expelling of
Louis IX from Egypt, which marked the end of the Crusaders' ambition to conquer the southern
Mediterranean basin; and the death of the Ayyubid dynasty and the birth of the Mamluk state which would dominate the southern Mediterranean for decades.

announced that he was merely a representative of the Abbasid caliph in Baghdad. To placate the Ayyubids in Syria, the Mamluks nominated an Ayyubid child named al-Sharaf Musa as a co-sultan.
But this did not satisfy the Ayyubids, and armed conflict between the Mamluks and the Ayyubids broke out. The Caliph in Baghdad, preoccupied with the Mongols who were raiding territories not far from his capital, preferred to see the matter settled peacefully between the Mamluks and the Ayyubids. Through the negotiation and mediation of the Caliph that followed the bloody conflict, the militarily superior Mamluks reached an agreement with the Ayyubids that gave them control over southern

and the Syrian coast. By this agreement, the Mamluks not only added new territories but also gained recognition for their rule.

In 1258, Hulagu invaded the Abbasid domain, which then consisted of only Baghdad, its immediate surroundings, and southern Iraq. In his campaign to conquer Baghdad, Hulagu Khan had several columns advance simultaneously on the city, and laid siege to it. The Mongols kept the people of Abbasid Caliphate in their capital and executed those who tried to flee.

soon afterward. It is reckoned that the Mongols did not want to shed "royal blood", so they wrapped him in a rug and trampled him to death with their horses. Some of his sons were massacred as well. The surviving son, Abu'l-Abbas Ahmad, was sent as a prisoner to Mongolia, where Mongolian historians report he married and fathered children, a daughter Aisha and a son Rukn al-Din Ahmad who had descendants, but played no role in Islam thereafter.

sent word to al-Musta'sim, demanding his acquiescence to the terms imposed by Möngke. Al-Musta'sim refused, in large part due to the influence of his advisor and grand vizier,
Ibn al-Alkami. Historians have ascribed various motives to Ibn al-Alkami's opposition to submission, including treachery
and incompetence,
and it appears that he lied to the caliph about the severity of the invasion, assuring al-Musta'sim that, if the capital of the caliphate was endangered by a Mongol army, the Islamic world would rush to its aid.
Although he replied to Hulagu's demands in a manner that the Mongol commander found menacing and offensive enough to break off further negotiation, al-Musta'sim neglected to summon armies to reinforce the troops at his disposal in Baghdad. Nor did he strengthen the city's walls. By 11 January, the Mongols were close to the city,

around the city. Al-Musta'sim finally decided to do battle with them and sent out a force of 20,000 cavalry to attack the Mongols. The cavalry were decisively defeated by the Mongols, whose sappers breached dikes along the Tigris River and flooded the ground behind the Abbasid forces, trapping them.
Siege

The Abbasid Caliphate could supposedly call upon 50,000 soldiers for the defense of their capital, including the 20,000 cavalry under al-Musta'sim. However, these troops were assembled hastily, making them poorly equipped and disciplined. Although the caliph technically had the authority to summon soldiers from other sultanates (caliphate's deputy states) to defence, he neglected to do so. His taunting opposition had lost him the loyalty of the Mamluks, and the Syrian emirs, whom he supported, were busy preparing their own defenses.
On 29 January, the Mongol army began its siege of Baghdad, constructing a palisade and a ditch around the city. Employing siege engines and catapults, the Mongols attempted to breach the city's walls, and, by 5 February, had seized a significant portion of the defenses. Realizing that his forces had little chance of retaking the walls, al-Musta'sim attempted to open negotiations with Hulagu, who rebuffed the caliph. Around 3,000 of Baghdad's notables also tried to negotiate with Hulagu but were murdered.
Five days later, on 10 February, the city surrendered, but the Mongols did not enter the city until the 13th, beginning a week of massacre and destruction.
Destruction and massacre
Many historical accounts detailed the cruelties of the Mongol conquerors. Contemporary accounts state Mongol soldiers looted and then destroyed mosques, palaces, libraries, and hospitals. Priceless books from Baghdad's thirty-six public libraries were torn apart, the looters using their leather covers as sandals. Grand buildings that had been the work of generations were burned to the ground. The

(the Grand Library of Baghdad), containing countless precious historical documents and books on subjects ranging from medicine to astronomy, was destroyed. Claims have been made that the Tigris ran red from the blood of the scientists and philosophers killed. Citizens attempted to flee, but were intercepted by Mongol soldiers who spared no one, not even children.
The caliph al-Musta'sim was captured and forced to watch as his citizens were murdered and his treasury plundered. According to most accounts, the caliph was killed by trampling. The Mongols rolled the caliph up in a rug, and rode their horses over him, as they believed that the earth would be offended if it were touched by royal blood. All but one of al-Musta'sim's sons were killed, and the sole surviving son was sent to Mongolia, where Mongolian historians report he married and fathered children, but played no role in Islam thereafter.
Hulagu had to move his camp upwind of the city, due to the stench of decay from the ruined city.
Baghdad was a depopulated, ruined city for several decades and only gradually recovered some of its former glory. The historian
David Morgan has quoted
Wassaf (who himself was born seven years after the razing of the city in 1265) describing the destruction:
They swept through the city like hungry falcons attacking a flight of doves, or like raging wolves attacking sheep, with loose reins and shameless faces, murdering and spreading terror...beds and cushions made of gold and encrusted with jewels were cut to pieces with knives and torn to shreds. Those hiding behind the veils of the great Harem were dragged...through the streets and alleys, each of them becoming a plaything...as the population died at the hands of the invaders.
Aftermath
Hulagu left 3,000 Mongol soldiers behind to rebuild Baghdad.
