About Alexandria
Alexandria (al-Iskandariyya) is the great Mediterranean port-city of northern Egypt, founded by Alexander the Great in 331 BCE and a leading centre of learning in antiquity. After the Muslim conquest of Egypt (642) it remained a major commercial and scholarly hub; the Shadhili Sufi Ibn Ata Allah al-Iskandari (d. 1309) took his nisba from the city, and the modernist reformer Muhammad Abduh (d. 1905) was active in Egypt's intellectual life there and in Cairo.
