Abd al-Rahman I
In spite of the restrictions placed upon the Jews as "dhimmis", life under Muslim rule was one of great opportunity and Jews flourished as they did not under the Christian Visigoths. Many Jews came to Iberia, seen as a land of tolerance and opportunity, from the Christian and Muslim worlds. Following initial Arab victories, and especially with the establishment of Umayyad rule by Abd al-Rahman I in 755, the native Jewish community was joined by Jews from the rest of Europe, as well as from Arab lands, from Morocco to Babylon. Jewish communities were enriched culturally, intellectually, and religiously by the commingling of these diverse Jewish traditions.
