Elizabeth of Carinthia
Elizabeth of Carinthia (1298?–1352) was the daughter of Otto III of Carinthia of the House of Gorizia. In 1323 she married King Peter II of Sicily and became queen, bearing the future kings Louis and Frederick IV.
When Peter died in 1342, her brother-in-law John of Randazzo ruled as regent for Louis; after John's death from plague in 1348 Elizabeth took the regency herself and steered the crown through feuding noble factions until her own death, probably of plague, in 1352.
