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 ar-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.
