1031 END OF UMAYYAD DYNASTY IN SPAIN
Hisham III (1027–1031) was overthrown . Beset by factionalism, the caliphate crumbled into a number of independent taifas or small principalities. The Umayyads had ruled with stability for 250 years. However, they never recovered from the Berber invasion and the sacking of Cordova twenty years earlier.Due to the general instability, many Jews emigrated to the Castile region especially to Toledo, or to Saragossa in Aragon. Others went to Leon or south to Almeria, and still others left for Egypt. As Jews moved away from established communities it led in many cases in a loosing of ties with the Jewish community, resulting in a rise in assimilation.
