Duke of Apulia and Calabria in the context of "Roger Borsa"

Roger II or Roger the Great (Italian: Ruggero II, Sicilian: Ruggeru II, Greek: Ρογέριος; 22 December 1095 – 26 February 1154) was King of Sicily and Africa, 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, then King of Sicily in 1130 and King of Africa in 1148.

Robert Guiscard (/ɡiːˈskɑːr/ ghee-SKAR, Modern French: [ʁɔbɛʁ ɡiskaʁ]; c. 1015 – 17 July 1085), also referred to as Robert de Hauteville, was a Norman adventurer remembered for his conquest of southern Italy and Sicily in the 11th century.

Robert was born into the Hauteville family in Normandy, the sixth son of Tancred de Hauteville and his wife Fressenda. He inherited the County of Apulia and Calabria from his brother in 1057, and in 1059 he was made Duke of Apulia and Calabria and Lord of Sicily by Pope Nicholas II. He was also briefly Prince of Benevento (1078–1081), before returning the title to the papacy.
