List of monarchs of Sicily
Sicily was granted, pending its Christian reconquest, to Robert Guiscard as "duke" in 1059 by Pope Nicholas II. The Guiscard granted it as a county to his brother Roger.
Roger II received royal investiture from Antipope Anacletus II in 1130 and recognition from Pope Innocent II in 1139. The Kingdom of Sicily, which by then comprised not only the island, but also the southern third of the Italian peninsula, rapidly expanded itself to include Malta and the Mahdia, the latter if only briefly.
Constance was married to the Emperor Henry VI and he pressed his claim to the kingdom from William II's death, but only succeeded in displacing his wife's family in 1194.
There is evidence that, during the baronial revolt of 1197, there was an attempt to make Count Jordan Lupin of Bovino king in opposition to Henry VI. He may even have been crowned and seems to have had the support of Constance, who had turned against her husband. In the end he was captured and executed. He is accepted as a pretender to the throne by modern historians Evelyn Jamison and Thomas Curtis Van Cleve.
Manfred was regent of Sicily for his nephew, the child Conrad II ("Conradin"), but took the crown in 1258, and continued to fight to keep the kingdom under the Hohenstaufen. In 1254 the pope, having declared the kingdom a papal possession, offered the crown to the King of England's son, Edmund Crouchback, but the English never succeeded in taking the kingdom. In 1262 the pope reversed his previous decision and granted the kingdom to the King of France's brother, Charles of Anjou, who succeeded in dispossessing Manfred in 1266. Conradin continued his claim to the throne until his death by decapitation perpetrated by Charles of Anjou in 1268.
