After Alexandria's status as the country's capital ended, it fell into a long decline, which by the late Ottoman period, had seen it reduced to little more than a small fishing village.
The current city is the Republic of Egypt's leading port, a commercial, tourism and transportation center, and the heart of a major industrial area where refined petroleum, asphalt, cotton textiles, processed food, paper, plastics and styrofoam are produced.
One of the more sober descriptions, given by the historian Arrian, tells how Alexander undertook to lay out the city's general plan, but lacking chalk or other means, resorted to sketching it out with grain.
[3] Alexandria was intended to supersede Naucratis as a Hellenistic center in Egypt, and to be the link between Greece and the rich Nile Valley.
If such a city was to be on the Egyptian coast, there was only one possible site, behind the screen of the Pharos island and removed from the silt thrown out by the Nile, just west of the westernmost "Canopic" mouth of the river.
[4] The site also offered unique protection against invading armies: the vast Libyan Desert to the west and the Nile Delta to the east.
[5] Inheriting the trade of ruined Tyre and becoming the center of the new commerce between Europe and the Arabian and Indian East, the city grew in less than a generation to be larger than Carthage.
[7] Nominally a free Hellenistic city, Alexandria retained its senate of Roman times and the judicial functions of that body were restored by Septimius Severus after temporary abolition by Augustus.
Luminaries associated with the Musaeum included the geometry and number-theorist Euclid; the astronomer Hipparchus; and Eratosthenes, known for calculating the Earth's circumference and for his algorithm for finding prime numbers, who became head librarian.
The reign of Ptolemy VIII Physcon from 144–116 BC was marked by purges and civil warfare (including the expulsion of intellectuals such as Apollodorus of Athens), as well as intrigues associated with the king's wives and sons.
Buildings were burned during the Kitos War (Tumultus Iudaicus) of AD 115, giving Hadrian and his architect, Decriannus, an opportunity to rebuild.
In 215 AD the emperor Caracalla visited the city and, because of some insulting satires that the inhabitants had directed at him, abruptly commanded his troops to put to death all youths capable of bearing arms[citation needed].
[15] As native influences began to reassert themselves in the Nile valley, Alexandria gradually became an alien city, more and more detached from Egypt and losing much of its commerce as the peace of the empire broke up during the 3rd century, followed by a fast decline in population and splendor.
Temples and statues were destroyed throughout the Roman empire: pagan rituals became forbidden under punishment of death, and libraries were closed.
Recent archaeology at Kom El Deka (heap of rubble or ballast) has found the Roman quarter of Alexandria beneath a layer of graves from the Muslim era.
The remains found at this site, which are dated circa the fourth to seventh centuries AD, include workshops, storefronts, houses, a theater, a public bath, and lecture halls, as well as Coptic frescoes.
The baths and theater were built in the fourth century and the smaller buildings constructed around them, suggesting a sort of urban renewal occurring in the wake of Diocletian.
Although the Byzantine Emperor Heraclius recovered it a few years later, in 641 the Arabs, under the general Amr ibn al-As during the Muslim conquest of Egypt, captured it decisively after a siege that lasted fourteen months.
The city received no aid from Constantinople during that time; Heraclius was dead and the new Emperor Constans II was barely twelve years old.
After a long decline, Alexandria emerged as major metropolis at the time of the Crusades and lived a flourishing period due to trade with agreements with the Aragonese, Genoese and Venetians who distributed the products arrived from the East through the Red Sea.
It formed an emirate of the Ayyubid Empire, where Saladin's elder brother Turan Shah was granted a sinecure to keep him from the front lines of the crusades.
The fourteenth and fifteenth centuries, Venice has eliminated the jurisdiction and its Alexandrian warehouse became the center of the distribution of spices to the Portuguese Cape route to open in 1498, which marks the commercial decline, worsened by the Turkish invasion.
[23] However, it declined still further under the Ottoman Empire, losing its water supply from the Nile, and its commercial importance, as Rosetta (Rashid) became more useful as a port.
[25] Muhammad Ali, the Ottoman Governor of Egypt, began rebuilding the city around 1810, and by 1850, Alexandria had returned to something akin to its former glory.
These clashes culminated in the Egyptian coup of 1952, during which the army occupied Alexandria and drove King Farouk from his residence at Montaza Palace.
Only a few months later, Alexandria's Manshia Square was the site of the famous, failed assassination attempt on the life of Gamal Abdel Nasser.
