ITALY: Sicily`s regional president, Sebastiano Musumeci, and orazio Iacono, CEO of Trenitalia, signed an operating contract on May 17. This is the first company agreement since the transfer of responsibility for rail transport to the region. The members of the delegation`s union, which deals with Cisl Medici, Fespa, Sumai and UIL FPL, were signed unanimously, an agreement in which the demands were presented jointly and strongly shared by all the acronyms that will now implement the necessary administrative procedure to bring them into the executive as quickly as possible by a specific legal act. The Treaty of Orvieto was a 1281 between Charles I of Sicily, Giovanni Dandolo, Doge of Venice, and Philip of Courtenay, titular emperor of the Latin Empire, with the blessing of the papacy. The intention to re-establish Latin, civil and ecclesial domination in Greece was prevented by the Sicilian Vespers War, which diverted Charlemagne`s resources for the restoration of Sicily. Negotiations to resolve the Sicilian question resumed in 1371 by the Chiaramonti, the most prominent noble family that supported the Aragonese claim to Sicily.   In January 1372, Johanna and Friedrich signed a preliminary contract without Gregory`s agreement.  In February, King Peter IV of Aragon and his Queen Eonenor, sister of Frederick IV, called on Pope Gregory, as supreme head of the former United Kingdom of Sicily, to invest Oneonora as queen of the island, on the grounds that Frederick was not competent to rule. The Aragonese monarchs even claimed that the Sicilian barons had asked for Elearnor as queen.  Although Gregor feared aragonese intervention, he was more interested in Naples` military support against his rival Bernabò Visconti, who now aspired to the alliance of Frederick of Sicily. Some sources even describe the colony`s initiative as coming from Gregory. In February, the Pope proposed that Frederick Antoinette des Baux (Antonietta del Balzo), daughter of Duke Francis of Andria, one of the leading magnates in John`s kingdom, marry to seal peace among his rivals.
 In the second half of 1372, Gregory sent John of New Year`s Eve to Naples to lead Queen Johanna over the proposed colony.  Gregory strove at the same time to preserve his right to the presidency over a reign in Sicily, to preserve the freedom of the Church from secular interference and to open the Italian markets to Sicilian cereals as soon as the papal ban on Sicily was lifted.  He insisted that Frederick pay homage to him and Johanna and pledge allegiance. . . .
