Plaisance of Antioch, the dowager queen of
Cyprus (and now regent of that kingdom); this possibility mandated that the Cypriot king
Hugh II, son of Plaisance, wed Edmund's sister
Beatrice. A second marriage alliance was also considered with one of the daughters of Manfred; the conditions of this marriage would see Manfred concede Sicily to Edmund after the marriage occurred. Ultimately, neither marriage came to fruition.
Domestic difficulties Henry III faced difficulties financing his son's accession to the Sicilian throne. The English were not enthusiastic about having to finance the endeavor and could not be persuaded otherwise, in spite of Henry III's pleads to be granted a subsidy. The King even paraded Edmund, donned in Sicilian royal regalia, before the English magnates at a parliament in 1257, but to no avail. Manfred's continued presence in the administration of Sicily proved to be a recurring issue as well; by 1257, he had taken control of the entire island of Sicily, and amidst rumours of Conradin's death, the 26-year-old Manfred was, in spite of the papacy's wishes, crowned King of Sicily on 10 August 1258 at
Palermo Cathedral and received homage from the Sicilian nobles. Despite the large sums forwarded to Rome thus far, Henry III still owed quite an amount. Rostand, who had returned to the Continent, returned to England in March 1257 with the
archbishop of Messina,
Giovanni Colonna, to request further payments. The two were received by the King and the twelve-year-old Edmund, who was dressed in
Apulian robes. In April, however, Henry III cancelled payments to the Pope, citing uncertainty as to whether he wished to continue with Edmund's bid for the throne. More lenient terms were offered to the English, but Henry III was commanded to reconcile with France and travel to Sicily by March 1259 with an army numbering no fewer than 8,500. Domestically, the "Sicilian business" was part of a wider array of political troubles that eventually gave rise to the 1258
Provisions of Oxford and attempts by the English barons to assert control over the monarchy. These magnates were discontent with many of the unpopular policies of Henry III's reign, including the alarming amount of money being allotted for Edmund's bid for the Sicilian throne, and the baronial government, which has been installed in accordance with the terms of the Provisions of Oxford, requested changes to the conditions of the Sicilian offer; on 18 December 1258, Alexander IV revoked the offer unless the previously discussed conditions were met. By this point, Alexander IV found it increasingly difficult to pay for the project, and facing military pressure, he dispatched an envoy to the English court and, with the threat of excommunication, demanded an army to be sent to Sicily and the payment of £90,000 from Henry III as financial compensation for the efforts to install Edmund. Requesting assistance from Parliament was again futile; seeing that he could not force the hands of his lay magnates, the King instead resorted to extorting money from the senior clergy of England, who were coerced into signing blank charters, promising to finance effectively unlimited sums of money in support of the "Sicilian business". In this manner, Henry III raised around £40,000. The English Church was displeased, feeling that the money was being wasted on a vain effort. Weiler argues that "...the baronial rebellion put an end to the Sicilian Business, but its demise was accidental rather than intentional. The problem his barons had with the king was not that he sought to get the Sicilian throne for his son, but how he went about getting it".
Failure and aftermath In March 1261, Edmund ordered the Sicilians to make preparations for his arrival, but on 28 July 1263,
Pope Urban IV () formally rescinded the grant of Sicily and sent the
archbishop of Cosenza, , to England to exonerate Edmund and his father of the terms of the Sicilian concession. Instead, Urban sent Albert to the court of Louis IX to again offer the throne of Sicily to Charles. The French prince was designated as King of Sicily and soon found himself beset by the same problems that had burdened Henry III, but he was eventually able to expel the Hohenstaufen. In 1266,
French forces defeated Manfred and
subdued Conradin two years later, securing Charles' rule in Sicily. ==Legacy==
