Question: Who was the emperor in Iraq during the 11th century?

History of Baghdad

The history of Baghdad begins when city of Baghdad (Arabic: بغداد‎ Baġdād) was founded in the mid 8th century  as the Abbasid capital, following the Abbasid victory over the Umayyad Caliphate. It replaced the Sassanid capital of Seleucia-Ctesiphon some 35km to the south-east, which was mostly depopulated by the end of the 8th century. Baghdad was the center of the Arab caliphate during the "Golden Age of Islam" of the 9th and 10th centuries, growing to be the largest city worldwide  by the beginning of the 10th century. It began to decline in the "Iranian Intermezzo" of the 9th to 11th centuries, and was destroyed in the Mongolian invasion in 1258.
The city was rebuilt and flourished under Ilkhanid rule but never rose to its former glory again. It was again sacked by Timur in 1401 and fell under Turkic rule. It was briefly taken by  Safavid Persia in 1508, before falling to the Ottoman Empire in 1534. With the dissolution of the Ottoman Empire, Baghdad fell under the British Mandate in 1920 and became the capital of the independent Kingdom of Iraq in 1932 (converted to a Republic in 1958).
As the capital of the modern Republic of Iraq, Baghdad has  a metropolitan area estimated at a population of 7,000,000 divided into numerous neighbourhoods in nine districts. It is the largest city in Iraq. It is the second-largest city in the Arab world (after Cairo) and the second-largest city in Western Asia (after Tehran). In recent history, Baghdad has been affected by the Iraqi civil war, most notably by recurring bombings.
Early history


Baghdad was found 1,250 years ago on 30 July 762. It was designed by caliph Al-Mansur. According to 11th-century scholar Al-Khatib al-Baghdadi – each course consisted of 162,000 bricks for the first third of the wall's height, 150,000 for the second third and 140,000 for the final section, bonded together with bundles of reeds. The outer wall was 80ft high, crowned with battlements and flanked by bastions. A deep moat ringed the outer wall perimeter.

Thousands of architects and engineers, legal experts, surveyors and carpenters, blacksmiths, diggers and ordinary labourers were recruited from across the Abbasid empire. First they surveyed, measured and excavated the foundations. Ya'qubi reckoned there were 100,000 workers involved. "They say that no other round city is known in all the regions of the world," Al-Khatib al-Baghdadi noted. Four equidistant gates pierced the outer walls where straight roads led to the centre of the city. The Kufa Gate to the south-west and the Basra Gate to the south-east both opened on to the Sarat canal – a key part of the network of waterways that drained the waters of the Euphrates into the Tigris. The Sham (Syrian) Gate to the north-west led to the main road on to Anbar, and across the desert wastes to Syria. To the north-east the Khorasan Gate lay close to the Tigris, leading to the bridge of boats across it.
The four straight roads that ran towards the centre of the city from the outer gates were lined with vaulted arcades containing merchants' shops and bazaars. Smaller streets ran off these four main arteries, giving access to a series of squares and houses; the limited space between the main wall and the inner wall answered to Mansur's desire to maintain the heart of the city as a royal preserve.
By 766 Mansur's Round City was complete. The ninth-century essayist, polymath and polemicist al-Jahiz said. "I have seen the great cities, including those noted for their durable construction. I have seen such cities in the districts of Syria, in Byzantine territory, and in other provinces, but I have never seen a city of greater height, more perfect circularity, more endowed with superior merits or possessing more spacious gates or more perfect defenses than Al Zawra (Baghdad), that is to say the city of Abu Jafar al-Mansur.
Center of learning (8th to 9th centuries)

Founder, caliph al-Mansur of the Abbasid caliphate, chose the city's location because of its critical link in trade routes, mild climate, topography (critical for fortification), and proximity to water. All of these factors made the city a breeding ground of culture and knowledge. Baghdad is set right on the Khurasan Road, which was an established meeting place for caravan routes from all cardinal directions.[1] During the construction of the city, gates were placed at the entrances of the major roads into the city, in order to funnel traffic into the city. The Kufah Gate was on a major road that pilgrims took to Mecca, and the Anbar gate linked the bridges over the canals and Euphrates River to the city. These were a substantial help at bringing people into the city, and around these entrances markets sprang up for travellers to trade at.[2] The link in trade routes provided a flood of goods into the city, which allowed numerous markets to spring up drawing people from all of the Middle East to Baghdad to trade. The markets that developed in Baghdad were some of the most sophisticated as well because of the government's supervision of their products as well as trade amongst each other.[1] Because of the sophisticated trading market, an advanced banking system developed as well, allowing further settlement from outsiders. Baghdad's location between the Tigris and Euphrates Rivers as well, created a trade link to further destinations such as China, India and Armenia, drawing even more people, literature, and knowledge to the city from exotic and distant lands.[3] The mild climate and topography made it easy to settle as well for travellers coming to the city to trade. As Baghdad became a trading hub in the Islamic Empire, cultures collided, sharing knowledge, books, language, and faiths, ultimately creating a "cosmopolitan city" that developed into a learning center for the world.[4]
As more and more people began to settle in the city, numerous schools began to spring up including the Hanafi and Hanbali schools of law. Law being a critical study for the Muslim people, because of the understanding of justice on Earth as applied to God.[1] The Hanafi is currently the largest school of legal thought in the Muslim world, and it was a major draw for scholars to the city of Baghdad. Another important school in Baghdad that began was the Bayt al-Hikma (House of Wisdom), which focused on translating texts from various languages into Arabic. This practice began out of a need to supply educated texts from around the world to a growing educated public market.[5] In particular the Arabic translation of Grecian texts became a substantial market that was quite progressive because its primary impetus from the caliphate was to establish a new ideology with a political and scientific base.[6] This translation helped to foster the transition between a primarily oral society, to one centered on a written language. Baghdad's location also made it ideal for paper production, which lowered the cost of creating books, making them more prevalent and accessible to more people.[4] As more and more texts began to be produced as well, a new market for book vendors opened up, and numerous libraries and bookstores sprang up in the city. As the public and private sectors of the community became more educated, cultural narrative and secular writing began. In the city, a demand for secular literature, designed for entertainment, developed, which shaped the culture of the city's population, as well as the Abbasid Empire as a whole, with Baghdad being their crowning achievement and reason for the Golden Age of Islam.[7] At this time, Baghdad was revered as the "center of the world" because of its scholarship. Michael Cooperson says that "Baghdadi scholars were so numerous and so eminent that reference to them could continue to support the 'center of the world' thesis…".[8] The influx of trade and commerce brought these scholars to the city, and made it the cosmopolitan breeding ground of knowledge that it became. Al-Mansur’s foundation and construction of the city as well, was done by only the best and brightest scholars, further fostering the notion of a highly intellectual city population to support the Golden Age.[9] At the height of the golden age in Baghdad, it was estimated that there were over one and half million people living in the city.[10]
Al-Mansur’s foundation of the city was ultimately based on its potential position as a military arsenal, and its ability to house and support many troops. Large numbers of troops were what originally gave the city such a dense population, but as the army continued to need supplies more and more people flooded to the city for jobs, thus being another reason Baghdad became a center of commerce.[11] Baghdad also being named the new capital of the Abbasid caliphate drew numerous people in for the prestige and name alone. Al-Mansur designated a governor of Baghdad and sent with him a number of elites who gave the city a higher status and poise, drawing more and more scholars to study in such a well-educated and cosmopolitan city.[12] Baghdad grew and developed in a variety of facets, and because of this it arguably became the largest city in the world during that time.
Stagnation and invasions (10th to 16th centuries)
By the 10th century, the city's population was between 300,000 and 500,000. 
Baghdad's early meteoric growth 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). Nevertheless, the city remained one of the cultural and commercial hubs of the Islamic world until February 10, 1258, when it was sacked by the Mongols under Hulagu Khan during the sack of Baghdad. The Mongols massacred most of the city's inhabitants, including the Abbasid Caliph Al-Musta'sim, and destroyed large sections of the city. The canals and dykes forming the city's irrigation system were also destroyed. The sack of Baghdad put an end to the Abbasid Caliphate, a blow from which the Islamic civilization never fully recovered.
At this point Baghdad was ruled by the Il-Khanids, part of the Mongolian Empire centred in Iran. The city was reconstructed and flourished under the Mongols. In 1401, Baghdad was again conquered, by Timur ("Tamerlane"). It became a provincial capital controlled by the Jalayirid (1400–1411), Qara Qoyunlu (1411–1469), Aq Quyunlu (1469–1508), and Safavid Persian (1508–1534) - (1604–1638) empires.
Ottoman Baghdad (16th to 19th centuries)
In 1534, Baghdad was conquered by the Ottoman Turks. Under the Ottomans, Baghdad fell into a period of decline, partially as a result of the enmity between its rulers and Persia. For a time, Baghdad had been the largest city in the Middle East before being overtaken by Constantinople in the 16th century. The city saw relative revival in the latter part of the 18th century under the Mamluk dynasty. The Nuttall Encyclopedia reports the 1907 population of Baghdad as 185,000.
20th century–present


Baghdad remained under Ottoman rule until the establishment of the kingdom of Iraq under British control in 1921. British control was established by a systematic suppression of Iraqi Arab and Kurdish national aspirations. Iraq was given formal independence in 1932, and increased autonomy in 1946. In 1958 the Ira, Faisal II. The city's population grew from an estimated 145,000 in 1900 to 580,000 in 1950.  During the 1970s Baghdad experienced a period of prosperity and growth because of a sharp increase in the price of petroleum, Iraq's main export. New infrastructure including modern sewage, water, and highway facilities were built during this period. However, the Iran–Iraq War of the 1980s was a difficult time for the city, as money flowed into the army and thousands of residents were killed. Iran launched a number of missile attacks against Baghdad, although they caused relatively little damage and few casualties.  In 1991 the first Gulf War caused damage to Baghdad's transportation, power, and sanitary infrastructure.

Baghdad was bombed very heavily in March and April 2003 in the 2003 invasion of Iraq, and fell under US control by April 7–9. Additional damage was caused by the severe looting[13] during the days following the end of the war. With the deposition of Saddam Hussein's regime, the city was occupied by U.S. troops. The Coalition Provisional Authority established a three-square-mile (8km²) "Green Zone" within the heart of the city from which it governed Iraq during the period before the new Iraqi government was established. The Coalition Provisional Authority ceded power to the interim government at the end of June 2004 and dissolved itself.

On September 23, 2003, a Gallup poll indicated that about two-thirds of Baghdad residents said that the removal of the Iraqi leader was worth the hardships they encountered, and that they expected a better life in five years' time. As time passed, however, support for the occupation declined dramatically. In April 2004, USA Today reported that a follow-up Gallup poll in Baghdad indicated that "only 13 percent of the people now say the invasion of Iraq was morally justifiable. In the 2003 poll, more than twice that number saw it as the right thing to do."[14]
Most residents of Baghdad became impatient with the coalition forces because essential services such as electricity were still unreliable more than a year after the invasion. In the hot summer of 2004, electricity was only available intermittently in most areas of the city. An additional pressing concern was the lack of security. The curfew imposed immediately after the invasion had been lifted in the winter of 2003, but the city that had once had a vibrant night life was still considered too dangerous after dark for many citizens. Those dangers included kidnapping and the risk of being caught in fighting between security forces and insurgents.
On 10 April 2007, the United States military began construction of a three-mile (5km) long 3.5 metre tall wall around the Sunni district of Baghdad.[15] On 23 April, the Iraqi Prime Minister, Nouri Maliki, called for construction to be halted on the wall.[16][17]
