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.
