Roger II of Sicily
Roger II (Mileto, Calabria 22 December 1095 – Palermo, Sicily 26 February 1154) was King of Sicily, son of Roger I of Sicily and successor to his brother Simon. He began his rule as Count of Sicily in 1105, became Duke of Apulia and Calabria in 1127, and then King of Sicily in 1130. By the time of his death at the age of 58, Roger had succeeded in uniting all the Norman conquests in Italy into one kingdom with a strong centralized government.
Background
By 999, Norman adventurers had arrived in southern Italy. By 1016, they were involved in the complex local politics where Lombards were fighting against the Byzantine Empire. These mercenaries fought the enemies of the Italian city-states, but in the following century they gradually became the rulers of the major polities south of Rome.
Roger I ruled the County of Sicily at the time of the birth of his youngest son, Roger, at Mileto, Calabria, in 1095. Roger I's nephew, Roger Borsa, was the Duke of Apulia and Calabria, and his great nephew, Richard II of Capua, was the Prince of Capua. Alongside these three major rulers were a large number of minor counts, who effectively exercised sovereign power in their own localities. These counts at least nominally owed allegiance to one of these three Norman rulers, but such allegiance was usually weak and often ignored.
