Previous story
Cairo's origins lie in several settlements. In today's city area was the place Cheri-aha, where according to Egyptian mythology the gods Horus and Seth fought each other. The ancient Egyptian settlement on the east bank of the Nile - the place was called "Babylon in Egypt" - was founded in the 1st century AD under the Romans in the time of Trajan and later developed into a fortress. The name Babylon arose from a misreading of the ancient Egyptian place name "House of the Nile of Heliopolis". Atum and the Nine were worshipped in Babylon. At the end of the 4th century the first Copts began to build churches and protective walls and to settle there.
On April 9, 641, the Arabs conquered the Eastern Roman fortress. Upon their arrival, they found a huge castle complex with 42 churches, large towers, and bastions. In the immediate vicinity of this, ʿAmr ibn al-ʿĀs founded the camp of Fustāt in 643, which gradually developed into a city. The two settlements grew together over time. While little remains of the early Islamic city of Fustāt except for wall remains and the ʿAmr-ibn-al-ʿĀs mosque, the Coptic quarter is preserved to this day.
Until the end of the 9th century, the town was a caravan camp and base and was of little importance to the Islamic rulers in Damascus (until 750) and Baghdad (from 750). The city experienced its first small boom under the Tulunids, for whom Fustāt served as the capital and who founded the settlement of al-Qatāʾiʿ in the immediate vicinity. Two structures survive from this period: The Ibn Tulun Mosque and the Nilometer. After this city was partially destroyed by fires, the Abbasids built another settlement on the Nile.
The founding of Cairo by the Fatimids
After the Fatimids under Dschauhar as-Siqillī had seized Egypt from the Ichshidids in 969, they built a new rectangular military camp four kilometers northeast of Fustāt. As al-Maqrīzī reports, construction began on July 6, 969. To the north of this camp, which was named like the North African residence of the Fatimid imam-caliph al-Mansūrīya, Dschauhar laid out a Musallā. Within the camp he built a Friday mosque, where Friday prayers were performed for the first time in June 971.
After Dschauhar had repelled the most significant Qarmatian attacks on Egypt, in the summer of 972 the Fatimid Imam-Caliph Abu Tamim al-Muizz made preparations to move his capital to the Nile. Dschauhar laid out a magnificent palace in the new camp city in the spring of 973, and the Imam-Caliph moved into it in the summer of the same year. On this occasion, the new palace city was renamed al-Qāhira al-Muʿizzīya ("the Victorious of Muʿizz"). In the shortened form al-Qāhira, this has remained the name of the city to this day. The mosque built by Dschauhar, which has been called the Azhar Mosque since 1010, remains the main mosque of Cairo to the present day and is the seat of the well-known al-Azhar University.
The new city was now the political center of an empire that stretched from Morocco to the Middle East. Fustāt also benefited from the political importance of the new neighboring city and developed into an international trading center. The Arab geographer al-Muqaddasī (946-1000) describes the city in the "Report on the Things I Saw with My Own Eyes" in 988 with the words:
"Al-Fustat is a metropolis in every sense [...]. It lies on the dividing line between the Maghreb and the residences of the Arabs, its terrain stretches far, it has many inhabitants, its territory is prosperous, its name famous, its prestige formidable. She is the metropolis of Egypt, eclipses Baghdad, is the pride of Islam, the trading-place of men, and more splendid than the city of peace. [Note: meaning Baghdad] It is the treasury of the Maghreb and the storehouse of the East, and brilliant at festival time. There is no metropolis more populous; many great and distinguished men live in her. She has goods and specialties worthy of wonder, beautiful markets and shops, not to mention baths. [...] in her there is fine food, pure ingredients, and pleasant sweets, many bananas and fresh dates, abundant vegetables and firewood, light water and wholesome air."
Fustat's great importance as an international trading center is also evident from the texts found in the geniza of the Ben Esra synagogue located in Fustat. In the course of time, however, Fustat was surpassed in economic importance by Cairo.
Only a few buildings survive from the Fatimid period in Cairo, including the al-Hākim Mosque and the al-Aqmar Mosque. When Saladin (1137-1193) returned Egypt to the Abbasid caliphate of Baghdad in 1171, Cairo became an important center of Sunni Islam. For Saladin, who had assumed leadership of the Arab world with the Ayyubid conquest of Cairo, the top priority was to eradicate the Shiite influences of the Fatimids. He had new mosques and schools built and created the foundations of what would become the Citadel. The Ayyubids were followed in 1250 by the Mamluks, who made Cairo the capital again. They had many palaces, mosques and caravanserais built to demonstrate their power. Cairo became the most important economic and cultural center of the Islamic world.
In 1304 the tomb complex of Salar and Sandshar al-Jauli and in 1345 the tomb mosque of Aslam as-Silahdar of Emir Aslam al-Baha'i as-Silahdar were built.
Ottoman and British rule
After the Battle of Raydaniyya, Cairo was conquered on April 13, 1517 by forces of the Ottomans, whose reign in Egypt lasted until the late 18th century. Egypt became an Ottoman province and Cairo lost much of its political importance. On July 24, 1798, French troops under Napoleon Bonaparte (1769-1821) took control of Cairo during his Egyptian expedition. On 18 June 1801, the city returned to Ottoman rule.
A real change of significance took place for Cairo in the 19th century with the emergence of the Khedive Empire. Ismail Pasha, who ruled between 1863 and 1879, had numerous buildings constructed in the city and used the opening of the Suez Canal in 1869 as an opportunity to present Cairo to the European powers as a flourishing metropolis. However, most of the development was financed through foreign loans, which increased Britain's influence in particular.
During the reign of Ismail Pasha, Cairo, which now became the capital again, expanded westwards across the Nile. European architects were commissioned to renew the city, the residential districts of Zamalek and Muhandisin were built, but large parts of today's city centre also date from this period. With Egypt's industrialization now accelerating, the country's capital continued to grow. By the end of the 19th century, Egypt's foreign debt and the weakness of the Ottoman Empire had resulted in a growing European influence in Cairo.
With the occupation of Egypt by British troops and the crushing of the Urabi movement (1881-1882), Britain took power without ending its formal assignment to the Ottoman Empire. The Khediv of Egypt formally remained a vassal of the Ottomans. The Urabi movement emerged in the autumn of 1881 when, following the financial ruin of Egypt under Ismail Pasha, the country came under international financial control. The movement opposed this international control of financial and economic policy and the autocratic rule of the dynasty of Muhammad Ali.

At the beginning of the 20th century, Cairo became the cultural capital. Even the fine English society was drawn there. Until the beginning of the First World War, there was a flurry of artistic activity. On December 18, 1914, Britain officially declared Egypt a British protectorate, severing the last formal ties with the Ottoman Empire. In addition, the British enforced the war economy, which led to widespread impoverishment of the population, as the purchasing power of the British troops caused food prices to rise sharply, but on the other hand, cotton prices were sharply reduced as a result of British intervention.
When the British prevented a delegation of Egyptian nationalists led by Saad Zaghlul (Wafd Party) from travelling to the Paris Peace Conference in 1919, serious riots, strikes and a boycott of British products ensued. Under this pressure, British High Commissioner Allenby prevailed to grant Egypt independence on February 28, 1922, so that British interests could continue to be safeguarded. Cairo remained the capital of the country.
After independence
Between the world wars, Cairo's population grew rapidly and had reached the two million mark by the start of the Second World War. The growth of the population continued in the following period. The onset of a building boom transformed the cityscape with towering residential, commercial and government buildings. On March 22, 1945, the Arab League was founded in Cairo.
After "Black Saturday" on 26 January, a major fire in Cairo during the 1952 riots, Cairo's population skyrocketed, and more and more rural refugees settled there. Numerous satellite towns sprang up; a housing shortage began and the city became an unmanageable metropolis. Today, the urban area includes places that were once several kilometers away from Cairo. The city government has begun to provide incentives through cheap rents and job creation to encourage the Cairo population to relocate to the satellite towns. But for every citizen who leaves the city, two are driven to it by rural migration.
In 1994, the United Nations World Population Conference was held in Cairo. The theme of this conference was problems with which Cairo is also confronted. In addition to overpopulation, these include above all poverty and the partly catastrophic hygienic and ecological situation.
From 1992 onwards, Islamic fundamentalists in Cairo carried out repeated attacks on domestic and foreign visitors in which people were killed. One of the most serious attacks in Cairo occurred on 18 September 1997, when nine Germans and one Egyptian died in an attack on a tourist bus outside a museum. The aim of these extremist groups is to discourage tourists from travelling to Egypt in order to break the domestic stability of the country, which is dependent on foreign currency.
In 2011, protests broke out among large parts of the population in Cairo. The revolution in Egypt in 2011 was primarily directed against the authoritarian regime with its extensive security apparatus, the lack of opportunities for citizens to have a say, and corruption in the state, economy and administration. In the same year, there was an attack on the churches of Imbaba and the Maspero massacre, in which numerous members of the Coptic minority were killed.
Population development
Cairo's population has grown rapidly over the past decades. It has doubled since the mid-1960s until today. One reason for this, in addition to the high birth rate, is the increasing rural exodus. In order to be able to absorb the constant population growth, several satellite cities have been formed around Cairo over the years.
Due to the tightly drawn city boundaries, the population increase in the city has now slowed down considerably; this is mainly taking place in the numerous suburbs, which with a combined population of around 8.2 million are now as populous as the city itself with 9.1 million inhabitants (2017). Giza alone accounts for almost 2.5 million inhabitants. The Cairo metropolitan region has a total population of 16.1 million (2008). The population of the metropolitan area is expected to exceed 24 million by 2050 and 40 million by 2100.
The following overview shows the population figures according to the respective territorial status. Until 1877 these are estimates, from 1882 to 2006 census results and 2008 a calculation. The population figures refer to the governorate (Arabic Muhafaza) of Cairo and do not include the other governorates of the agglomeration, Giza and Qaliubia.
| Year | Inhabitants | | 1800 | 200.000 | | 1859 | 254.000 | | 1865 | 282.300 | | 1870 | 313.400 | | 1877 | 327.500 | | 1882 | 374.838 | | 1897 | 570.062 | | 1907 | 654.476 | | 1917 | 790.939 | | 1927 | 1.059.800 | | | Year | Inhabitants | | 1937 | 1.312.096 | | 1947 | 2.090.654 | | 1960 | 3.349.000 | | 1966 | 4.219.900 | | 1976 | 5.084.463 | | 1986 | 6.052.836 | | 1996 | 6.789.479 | | 2006 | 7.786 640 | | 2008 | 7.947.121 | | 2017 | 9.153.135 | |
Development of the housing situation
About half of the population of the Cairo metropolitan region lives in so-called informal settlements, dwellings illegally built on the outskirts of the city by rural refugees, with inadequate infrastructure and a high population density. As a suspected place of residence for Islamic fundamentalists, they are the focus of Egyptian security policy.
While numerous people search in vain for affordable housing, several hundred thousand apartments in the region are vacant. One reason for this is that rents for old buildings are frozen at 1950s levels. The houses are therefore exposed to rapid deterioration, as the rents are not sufficient to finance the necessary repairs.
For new buildings, rents are set by the state at such a low level that either an illegal payment is demanded from the tenant before the lease is signed, which is approximately the amount of the construction costs for the apartment, or it is immediately put up for sale. The legal protection against dismissal prevents their later use by the owner.
Legally, but not statistically recorded, an almost village-like residential scene has formed on the flat roofs of many buildings. The residents have no written contract, but are tolerated. In return, they perform auxiliary services for the rent-paying residents, e.g. as caretakers. Relatives and friends live in self-built huts. Pets are also kept.
Real estate speculation in condominiums also contributes to the fact that many apartments in the region are vacant. After the reduction of state subsidies for food, energy and public transport, the poorer sections of the population cannot afford to rent or buy a condominium.
The Imbaba slum is one of the largest slums in the world.
In a 2018 ranking of cities by quality of life, Cairo ranked 178th among 231 cities surveyed worldwide.
Earthquake 1992
On 12 October 1992, an earthquake measuring 5.8 on the Richter scale struck Cairo at 15:09 local time. Around 550 people were killed by the quake. Thousands of buildings, mainly in the poor districts of the Old City, were destroyed and some 50,000 people lost their homes; valuable historic buildings such as the al-Azhar Mosque also suffered severe damage. The epicentre of the earthquake was around 26 kilometres southwest of Cairo, in the vicinity of the pyramids of Dahshur. It was the strongest earthquake in Cairo since 1847.

As the largest city in the Arab world and the capital of the most populous Arab country, Cairo was also a centre of the "Arab Spring" from 2010 onwards. The 2011 revolution in Egypt, which essentially took place in Cairo, led to the fall of the authoritarian regime of President Hosni Mubarak in 2011. Tahrir Square in Cairo was at the center of international news coverage, both because violent clashes between police forces and protesters took place here, and because disturbing instances of public sexual violence against women occurred here during the revolution (and continue to occur here today). After Islamic and Islamist groups such as the Muslim Brotherhood were successful in the 2011 and 2012 parliamentary and presidential elections, numerous demonstrations by political opponents again took place. In 2013, there was a military coup and the removal of the elected president from the Muslim Brotherhood, Mohammed Mursi. The 2014 presidential election was won by the military's candidate Abd al-Fattah as-Sisi, with the Muslim Brotherhood barred from participating in the election. From 2010 to 2014, the security situation in Cairo was tense and the city was rocked by mostly Islamist-motivated bombings. Before the anniversary of the Egyptian revolution in January 2014, six people died in four attacks. On 11 July 2015, one person died in a bomb attack on the Italian consulate. On 20 August 2015, a car bombing caused at least 29 injuries. On December 4, 2015, at least 16 people died in an attack on a nightclub. On 11 December 2016, a bombing at St Mark's Coptic Cathedral killed at least 25 people.
