Succession of Roger Borsa in Sicily

Timeline

1. 1085Cephalonia · Ionian IslandsThe Norman conqueror of southern Italy, Robert Guiscard, died of illness during his expedition against Byzantium, leaving a partitioned will: his legitimate son Roger Borsa inherited the duchy, his half-brother Bohemond received Taranto, and his brother Roger I continued to rule Sicily.
2. 1085Apulia · ApuliaWith the support of the Church and some Norman nobles, Roger Borsa formally inherited the titles of Duke of Apulia and Calabria, becoming nominal overlord of southern Italy, though his actual control was constrained by his brothers and the barons.
3. 1085Southern Italy · Southern ItalyBohemond was dissatisfied with the partition and Blesa rose in revolt, plunging the Norman domains into division. Roger I of Sicily, though an uncle, remained relatively independent, and the hegemony of southern Italy shifted from Guiscard's personal rule to a fragile feudal co-rule.
