At the time of the Battle of Yarmuk when the Levant passed under Muslim Rule, thirty Jewish communities existed in Haifa, Sh'chem, Hebron, Ramleh, Gaza, Jerusalem, and many in the north. Safed became a spiritual centre for the Jews and the Shulchan Aruch was compiled there as well as many Kabbalistic texts. The first Hebrew printing press, and the first printing in Western Asia began in 1577.
