County of Sicily was created by Robert Guiscard in 1071 for his younger brother Roger Bosso. Guiscard himself had received the title Duke of Sicily ("dux Siciliae") in 1059 from Pope Nicholas II as encouragement to conquer it from the Muslims. In 1061 the first permanent Norman conquest (Messina) was made and in 1071, after the fall of Palermo, the capital of the emirate and future capital of the county, Guiscard invested Roger with the title of count and gave him full jurisdiction in the island save for half the city of Palermo, Messina, and the Val Demone, which he retained for himself.
Syracuse, Sicily agreed signal, during a diversionary attack, he opened the gate. After setting guards on the houses of the pro-Roman faction, Marcellus gave Syracuse to plunder. Though declining slowly through the years, Syracuse maintained the status of capital of the Roman government of Sicily and seat of the praetor. It remained an important port for trade between the Eastern and the Western parts of the Empire. Christianity spread in the city through the efforts of Paul of Tarsus and Saint Marziano, the first bishop of the city, who made it one of the main centres of proselytism in the West. In
