Who married Peter II of Sicily?

Peter II (Latin: Petrus, Italian: Pietro, Sicilian: Pietru; 1304 – 8 August 1342) was the King of Sicily from 1337 until his death, although he was associated with his father as co-ruler from 1321. Peter's father was Frederick III of Sicily and his mother was Eleanor, a daughter of Charles II of Naples. His reign was marked by strife between the throne and the nobility, especially the old families of Ventimiglia, Palizzi and Chiaramonte, and by war between Sicily and Naples.

Contemporaries regarded Peter as feeble-minded. Giovanni Villani, in his Nuova Cronica, calls him "almost an imbecile" (Italianate Latin: quasi un mentacatto) and Nicola Speciale, in his Historia Sicula, calls him "pure and simple" (purus et simplex).

Under Peter, the Neapolitans conquered the Lipari Islands and took the cities of Milazzo and Termini in Sicily itself. He died after a short illness on 8 August 1342 in Calascibetta and was buried in the cathedral of Palermo. He was succeeded by Louis, his eldest son, who was only four years old.

Elizabeth of Carinthia (1298–1352) was Queen of Sicily by marriage to Peter II of Sicily. She was the regent of Sicily during the minority of her son Louis, King of Sicily from 1348 until her death in 1352.

The daughter of Otto, the penultimate duke of Carinthia and lord of Carniola from the House of Gorizia, she married Peter II of Sicily in 1323 and became the Queen of Sicily. During her time as Queen, Elizabeth ensured that the royal lineage of the Aragonese in Sicily continued. Two sons eventually ascended the throne, Louis of Sicily and Frederick IV of Sicily. Elizabeth was the regent for her young son Louis from 1348 until her death in 1352.

Politically, the decades leading up to Elizabeth's reign were full of conflicts between Frederick III, King of Sicily, and Robert of Naples who had the backing of the papacy in Avignon. Famine, warfare and plague were widespread in Europe during the mid-fourteenth century, which had a devastating impact on Sicily in particular, due to its economic expansion and prosperity in the two centuries prior. Elizabeth's reign occurred during a period where Italian citizens were disheartened and anxious, which caused tension among the local populace. The island was also marked by turbulent relations between the throne and Sicily's noble families, eventually degenerating into a civil war. These internal rivalries between the noble families required the coming of age of Elizabeth's sons to resolve the fighting.
