rule in Sicily under Holy Roman Emperors Henry VI and his son, Frederick II. Many repressive measures were introduced by Frederick II to appease the popes, who were intolerant of Islam in the heart of Christendom. This resulted in a rebellion by Sicilian Muslims, which in turn triggered organized resistance and systematic reprisals and marked the final chapter of Islam in Sicily. The complete eviction of Muslims and the annihilation of Islam in Sicily was completed by the late 1240s when the final deportations to Lucera took place. The remaining population of Sicilian Muslims converted to Catholicism due to the incentives put in place by Fredrich II. Some Muslims from Lucera would also later convert due to oppression on the mainland and had their property returned to them and returned to Sicily. During the reigns of Frederick II as well as his son, Manfred, a large amount of Muslims were brought, as slaves, to farm lands and perform domestic labor. Enslaved persons in Sicily were not afforded the same privileges as the Muslims in mainland Italy. The trend of importing a considerable amount of slaves from the Muslim world did not stop with the Hohenstaufen but was amplified under the Aragonese and Spanish crowns, and was in fact continued until as late as 1838 The majority of which would also come receive the label 'Moors' Architecture Moorish architecture is the articulated Islamic architecture of northern Africa and parts of Spain and Portugal, where the Moors were dominant between 711 and 1492. The best surviving examples of this architectural tradition are the Mosque–Cathedral of Córdoba and the Alhambra in Granada (mainly 1338–1390), as well as the Giralda in Seville (1184). Other notable examples include the ruined palace city of Medina Azahara (936–1010) and the Mosque of Cristo de la Luz, now a church, in Toledo, the Aljafería in Zaragoza and baths such as those at Ronda and Alhama de Granada. In heraldry Moors—or more frequently their heads, often crowned—appear with some frequency in medieval European heraldry, though less so since the Middle Ages. The term ascribed to them in Anglo-Norman blazon (the language of English heraldry) is maure, though they are also sometimes called moore, blackmoor, blackamoor or negro. Maures appear in European heraldry from at least as early as the 13th century, and some have been attested as early as the 11th century in Italy, where they have persisted in
