many of the Arab towns in Sicily, and very few physical remains survive from the Arab era. The Norman Hauteville family, descendants of Vikings, appreciated and admired the rich and layered culture in which they now found themselves. They also introduced their own culture, customs, and politics in the region. Many Normans in Sicily adopted the habits and comportment of Muslim rulers and their Byzantine subjects in dress, language, literature, even to the extent of having palace eunuchs and, according to some accounts, a harem. Kingdom of Sicily While Roger I died in 1101, his wife Adelaide ruled until 1112 when their son Roger II of Sicily came of age. Having succeeded his brother Simon as Count of Sicily, Roger II was ultimately able to raise the status of the island to a kingdom in 1130, along with his other holdings, which included the Maltese Islands and the Duchies of Apulia and Calabria. Roger II appointed the powerful Greek George of Antioch to be his "emir of emirs" and continued the syncretism of his father. During this period, the Kingdom of Sicily was prosperous and politically powerful, becoming one of the wealthiest states in all of Europe—even wealthier than the Kingdom of England. The court of Roger II became the most luminous centre of culture in the Mediterranean, both from Europe and the Middle East, like the multi-ethnic Caliphate of Córdoba, then only just eclipsed. This attracted scholars, scientists, poets, artists, and artisans of all kinds. Laws were issued in the language of the community to whom they were addressed in Norman Sicily, at the time when the culture was still heavily Arab and Greek. Governance was by rule of law which promoted justice. Muslims, Jews, Byzantine Greeks, Lombards, and Normans worked together fairly amicably. During this time many extraordinary buildings were constructed. However this situation changed as the Normans imported immigrants from Normandy, England, Lombardy, Piedmont, Provence and Campania to secure the island. Linguistically, the island shifted from being one-third Greek- and two-thirds Arabic-speaking at the time of the Norman conquest to becoming fully Latinised. In terms of religion the island became completely Roman Catholic (bearing in mind that until 1054 the Churches owing allegiance to the Pope and the Patriarch of Constantinople belonged to one Church); Sicily before the Norman conquest was under Eastern Orthodox Patriarch. After Pope Innocent III made him Papal Legate in 1098, Roger I
