750 - 1258 ABBASID DYNASTY (from Abu Abbas) (Persia)
Expanded intellectual horizons and world trade. The Abbasids gained control from the Umayyads after the assassination of Marwan II in Egypt and moved the control to Baghdad. Eighty members of Marwan II's family were also killed at Antipatris near present day Rosh Haayin. Abd Al(ur)-Rahman, one of the surviving members of the Umayyads, reached Cordova and set up his own Caliphate (see 756). The Abbasids gave more power to the Persians and Turkish tribes, with Caliphs taking upon themselves absolute authority .Although, as with the Umayyad Dynasty, the Jewish position depended on the current ruler, in general, Jews began to play an important role in world trade and banking.
