Toledo School of Translators
During most of the medieval period, intermarriage with converts was allowed and encouraged. Intellectual cooperation between religions was the norm in Castile. Some examples are the Toledo School of Translators from the 11th century. Jews and Moors were allowed to hold high offices in the administration (See Abrahám Seneor, Samuel HaLevi Abulafia, Isaac Abarbanel, López de Conchillos, Miguel Pérez de Almazán, Jaco Aben Nunnes and Fernando del Pulgar).
