Despite ousting the Muslims from power, the Normans were very receptive to the former's culture. The new dynasty employed Muslim scholars in its courts, soldiers in its army, and even women in its harems. With the switch from Norman to Swabian power, Muslim influence steadily declined. When Frederick II brought many of the rebelling Muslims to a colony called Lucera on the Italian mainland, much of the Muslim presence slowly became insignificant. During the height of the Ottoman power, raids on the Sicilian coasts became frequent until that Muslim power also declined.

Due to successful naval campaigns in North Africa, Roger will later add King of Ifriqiyya to his name. Many Muslims play active roles in his court such as Abu'd-Daw, Abd al-Rahman ibn Muhammad ibn Omar, and the celebrated al-Idrisi. His reign also sees the employment of "palace Saracens," castrated Muslims who had converted to Christianity. These eunuchs, who hold very prominent official roles, will often be accused of being covert Muslims and protecting Christian reverts to Islam.
