context_page_description: Baghdad is the capital of Iraq and the third-largest city in the Arab world after Cairo and Riyadh. Located along the Tigris River, the city was founded in the 8th century, and became the capital of the Abbasid Caliphate. Within a short time of its inception, Baghdad evolved into a significant cultural, commercial, and intellectual center of the Muslim world. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as hosting a multiethnic and multireligious environment, garnered the city a worldwide reputation as the "Centre of Learning".
  Baghdad was the largest city in the world for much of the Abbasid era during the Islamic Golden Age, peaking at a population of more than a million. The city was largely destroyed at the hands of the Mongol Empire in 1258, resulting in a decline that would linger through many centuries due to frequent plagues and multiple successive empires. With the recognition of Iraq as an independent state in 1932, Baghdad gradually regained some of its former prominence as a significant center of Arabic culture, with a population variously estimated at 6 or over 7 million.
context_section_description: By the 10th century, the city's population was between 1.2 million and 2 million. Baghdad's early meteoric growth eventually slowed due to troubles within the Caliphate, including relocations of the capital to Samarra (during 808–819 and 836–892), the loss of the western and easternmost provinces, and periods of political domination by the Iranian Buwayhids (945–1055) and Seljuk Turks (1055–1135).
  The Seljuks were a clan of the Oghuz Turks from Central Asia that converted to the Sunni branch of Islam. In 1040, they destroyed the Ghaznavids, taking over their land and in 1055, Tughril Beg, the leader of the Seljuks, took over Baghdad. The Seljuks expelled the Buyid dynasty of Shiites that had ruled for some time and took over power and control of Baghdad. They ruled as Sultans in the name of the Abbasid caliphs (they saw themselves as being part of the Abbasid regime). Tughril Beg saw himself as the protector of the Abbasid Caliphs.

  In 1058, Baghdad was captured by the Fatimids under the Turkish general Abu'l-Ḥārith Arslān al-Basasiri, an adherent of the Ismailis along with the 'Uqaylid Quraysh. Not long before the arrival of the Saljuqs in Baghdad, al-Basasiri petitioned to the Fatimid Imam-Caliph al-Mustansir to support him in conquering Baghdad on the Ismaili Imam's behalf. It has recently come to light that the famed Fatimid da'i, al-Mu'ayyad al-Shirazi, had a direct role in supporting al-Basasiri and helped the general to succeed in taking Mawṣil, Wāsit and Kufa. Soon after, by December 1058, a Shi'i adhān (call to prayer) was implemented in Baghdad and a khutbah (sermon) was delivered in the name of the Fatimid Imam-Caliph. Despite his Shi'i inclinations, Al-Basasiri received support from Sunnis and Shi'is alike, for whom opposition to the Saljuq power was a common factor.
  On 10 February 1258, Baghdad was captured by the Mongols led by Hulegu, a grandson of Chingiz Khan (Genghis Khan), during the siege of Baghdad. Many quarters were ruined by fire, siege, or looting. The Mongols massacred most of the city's inhabitants, including the caliph Al-Musta'sim, and destroyed large sections of the city. The canals and dykes forming the city's irrigation system were also destroyed. During this time, in Baghdad, Christians and Shia were tolerated, while Sunnis were treated as enemies. The sack of Baghdad put an end to the Abbasid Caliphate. It has been argued that this marked an end to the Islamic Golden Age and served a blow from which Islamic civilisation never fully recovered.
  At this point, Baghdad was ruled by the Ilkhanate, a breakaway state of the Mongol Empire, ruling from Iran. In August 1393, Baghdad was occupied by the Central Asian Turkic conqueror Timur ("Tamerlane"), by marching there in only eight days from Shiraz. Sultan Ahmad Jalayir fled to Syria, where the Mamluk Sultan Barquq protected him and killed Timur's envoys. Timur left the Sarbadar prince Khwaja Mas'ud to govern Baghdad, but he was driven out when Ahmad Jalayir returned.
  In 1401, Baghdad was again sacked, by Timur. When his forces took Baghdad, he spared almost no one, and ordered that each of his soldiers bring back two severed human heads. Baghdad became a provincial capital controlled by the Mongol Jalayirid (1400–1411), Turkic Kara Koyunlu (1411–1469), Turkic Ak Koyunlu (1469–1508), and the Iranian Safavid (1508–1534) dynasties.
