Then came the Arabs.
[The] Caliph Muiz had invested a fortune of his own to conquer Egypt, so he obviously wanted to get back his investment as quickly as possible, and as always the Red Sea Canal was to be implement of his wealth. The customs port of Al Maks, which means “customs tax,” lay in the bend of the river which came almost up to the walls of Kahira on the west side near the canal, and this Mu’iz immediately took over and expanded into a proper dockyard, keeping its tax collecting character but also laying the foundations there for a new port of his own, which immediately took away much of the business that usually went to Fustat-Misr.
Here Mu’iz built six hundred ships and about 77 years later, when Nasir Ibn Khusrau came to Cairo [in the 11th century], seven of his ships were still lying on the river bank. “I, the author of this narrative, Ibn Khusrau says: ‘I have seen them’”. They mea sured thirty erich by sixty arech (275 feet long by 110 feet abeam). These ships were no doubt a brilliant investment because they could move large quantities of cargo at one time, rather like the modern monstrous oil tankers. Nothing that could make money escaped Mu’iz, and he reorganised the whole tax system into a central collecting body which did away with the local collectors, who used to take a considerable rake-off of their own. In one day he collected over 475,000 US dollars (modern equivalent) in taxes from Fustat-Misr alone.4
In A History of Egypt in the Middle Ages, Stanley Lane Poole tells us, One hundred and twenty thousand labourers were kept at work winter and summer in maintaining and improving dams and canals. The old canal traditionally called the Amnis Trajanus connecting Babylon (Cairo) with the Red Sea was cleaned and reopened in less than a year and corn was sent to Medina by ship instead of by caravan as in the previous year.5
In short, a wealth of evidence from Greek, Roman, and Arab writers states that the canal enabled ships to carry goods from the Nile to the Red Sea and vice versa. Grain was transported from the wheat fields of the Sudan to Rome, Mecca, Arabia, and India. Chinese porcelain and silk could be brought to Rome, Venetian glass to India.
In 642, Amir ibn Al-As dredged out the old canal, which was filling with silt brought down by the Nile. A century later there was a rebellion in Mecca and Medina, and in 767 the Abbasid Abu Ja’far al-Mansur blocked the canal to stop corn supplies from reaching Mecca. Shortly afterward, in 780, during the caliphate of Al Mahdi the canal was reopened. Then in 870 Ahmad ibn Tulun dredged the canal once again, and a further expansion took place in 955.
The next huge improvement to the canal was caxrried out by Sultan al-Malik an-Nasir in 1337, who assigned no fewer than 100,000 men to the job. He also built the Nilometer on the south of Roda island, which can be seen to this day. It mea sured the height of the river and thus served as a flood warning.
This final canal widening and dredging is summarized by historian James Aldridge in Cairo: Biography of a City, based on descriptions by the fifteenth-century Egyptian historian al-Madkrizi:
The land which emerged round Elephant Island was marshy and soft and Makrizi, who tells us all this, says the Mamluks used to practise archery there. But in the middle of the fourteenth century Al Nazir joined the Red Sea canal to the new bank of the river through this new swampy land, thus draining it. This new exit for the old canal was called Khalig Al Nasir, and it remained the exit of the Red Sea canal until this century, although it was later diverted again and called the Ismailiya Canal. It met the river where the Egyptian Pharaonic Museum is now, near the Nile Hilton. This final version of Nazir’s canal was only filled in at the end of the nineteenth century to make what is now Rameses II Street, and anyone with a moment to spare on top of the Nile Hilton can look down on this street and trace the line of the old canal right up to the station square which was once the port of Al Maks.6
As we have noted, one of the Chinese names for Cairo was Misr, a name derived from the pharaonic name for the river port in Babylon. As time passed, Al-Fustat and Misr became interchangeable names for the port and the city of Cairo, “no doubt because all trade with Egypt was directed eventually to the river port of Misr or it came from Misr,” Aldrich explains. “So it seems logical that sooner or later it was all known as Fustat-Misr (which is what al-Makrizi often calls it) and then simply as Misr. Today, Egyptians still call both their country and Cairo simply Misr.”
On November 26, 2004, the Oriental Ceramic Society of France held a conference in Paris on trade between China and the Mediterranean prior to the sixteenth century. The conference produced a wealth of fascinating detail about the export of Chinese ceramics to Egypt, the Middle East, and the Mediterranean.7
Excavation sites in the southern suburbs of Cairo have produced Chinese ceramics dating from the tenth to the fourteenth centuries. In “Chinese Porcelain from Fustat,” archaeologist R. L. Hobson describes the significance of the porcelain and ceramics finds:
…Turning over the piles of fragments stored at Fustat and in the Arab Museum in Cairo…we realise most clearly the extent and antiquity of the trade between Egypt and the Far East. There are, for instance, pieces of buff stoneware with cream glaze mottled with green and brownish yellow, which came from China in the Tang dynasty; there are several varieties of celadon porcelain which tell of Sung traders. And there are blue and white porcelains ranging from the Yuan to the end of the Ming period….
The typical Lung ch’uan and ch’u-chou celadons of the Sung, Yuan and Ming periods abound, bowls and dishes with carved designs or with reliefs of fishes or rosettes, things too well known to call for detailed notice….
It was only natural that the volume of trade with China should increase in the Ming dynasty…. This is evidenced in Egypt by the large quantity of blue and white porcelain, of which fragments abound not only at Fustat, but all around Cairo.
…Among the earliest specimens is the bottom of a bowl with the reign-mark of Yung Lo (1403–1424)”—viz Zhu Di.8
This extraordinary trade in porcelain and ceramics was lubricated by the Karim. The Karim had their own warehouses (fonduqs) stretching from Cairo to India and beyond. They built their own ships and sometimes leased them to others. They also operated as bankers, which proved to be their undoing.
In 1398 the Karim made a massive loan to the Mamluk sultan, to finance an army to halt Tamburlaine’s march toward Cairo. When the loans were called, the sultan came up short. Al-Ashraf Barsbay nationalized the Nile–Red Sea canal to replenish his coffers, setting the prices at which goods brought through Egypt could be bought and sold. With a single stroke, the security for the Karim’s loans—trade through the canal—unraveled. The Karim were ruined within decades. When China withdrew from the world stage in the 1430s, after Zheng He’s final voyage, Chinese goods came no more.
