In this atmosphere of increasing feudalisation, the goal of the Sicilian throne to maintain the dynasty from the House of Aragon after the death of Frederick III in 1337 was soon to deteriorate. Elizabeth's coat of Arms was shared by the competing baronial factions, yet several powerful and power-hungry figures emerged to challenge royal power, serving as the heads of competing family lines. These included the families of the Chiaramonte, the Palizzi, the Scaloro degli Uberti, the Peralta, the Alagona and the Ventimiglia. As historian Henri Bresc describes, several dynastic "war cries" were heard from these families around Sicily in the years of Elizabeth's regency and beyond, in places such as Palermo in 1348, Fontanarossa in 1349, Noto in 1349, Vizzini in 1353, Polizzi in 1354, and Naso in 1356. Yet the causes of this threat to the throne's rule did not arise, in these families of the Sicilian aristocracy, from factors such as inter-familial agreements and solidarity, but personal ambition and the goal of maintaining it for a family's posterity, through the bestowing of rule to their children. As a result, betrayals in this brew of competing families were common, and any agreement or coalition between them had ill-defined borders, easily liable to be crossed breached. When Elizabeth's husband, Peter II of Sicily took to the throne after the death of Frederick III of Sicily in 1337, the Palizzi were expelled from Sicily. However his reign lasted for merely five years, as Peter II died in 1342. Thereupon Elizabeth and Peter's son Louis, King of Sicily (Ludovico or Luigi in Italian) took to the throne, Louis being only a child of five years of age. He was to be the object of the competing intrigues of Sicily's baronial families.
