808 FEZ (Morocco)
Re- established the city of Fez which had been founded by his father Idris I twenty years earlier. The city was first built on one river bank ( Madinat Fas) in 788. Idris II (791-828) built an additional, and competing city (Al-'Aliya) on the other side which became his capitol. Idris II encouraged Jews to live freely in their own quarter, in return for an annual tax. The city soon became a commercial center, and schools of Jewish learning were established. One of its earliest scholars was Judah ibn Quraysh, a Semitic linguist and grammarian who was fluent in Hebrew, Aramaic and Arabic.
