アブド・アッラフマーン3世
The longest period of relative tolerance began after 912 with the reign of Abd-ar-Rahman III and his son, Al-Hakam II, when the Jews of al-Andalus prospered, devoting themselves to the service of the Caliphate of Córdoba, to the study of the sciences, and to commerce and industry, especially trading in silk and slaves, in this way promoting the prosperity of the country. Southern Iberia became an asylum for the oppressed Jews of other countries.
