Elizabeth of Carinthia (1298–1352) was an influential queen and royal family member in the Kingdom of Sicily, who lived and ruled in a tumultuous time. The daughter of the 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.
