Queenship
On 23 April 1323, Elizabeth married Peter II of Sicily (Trinacria), son of Frederick III, King of Sicily (Trinacria) (1271–25 June 1337) and Eleanor of Anjou (1289–9 August 1341) a little more than a year after his coronation. Speculation by Francesco Testa suggests that Elizabeth was not Frederick III's first choice for a daughter-in-law. Frederick wished to marry his heir to Beatrice, the daughter of the Holy Roman Emperor, Henry. Instead, Beatrice married Charles of Hungary, a nephew of king Robert of Naples, Frederick's main enemy. In turn, Frederick married his eldest son and heir to Elizabeth of Carinthia, whose family was in fierce rivalry to Beatrice's (John of Luxembourg, Beatrice's brother, had taken the Bohemian crown from Elizabeth's uncle and caretaker Henry). The lavish ceremonies of the wedding and coronation served as reminders to Sicilian nobility of the power of the royalty, a struggle the Aragonese family had been battling for years. Elizabeth's reign as regent would be marked by the tensions created over these struggles.
As the queen, Elizabeth's primary occupation was the production of viable heirs for the Sicilian throne, as task she took up soon after marriage. Less than two years after their wedding, Peter II and Elizabeth had a son in Messina in February 1324, whom they named Frederick and buried a few months later. Following the death of their first born, Elizabeth and Peter II had seven more children, their first four daughters whom survived to maturity were; Constance (1324–October 1355), regent of Sicily for her younger brother, Louis, from 1352 to 1354 following the death of her mother, Elizabeth. Constance never married. Their second daughter, Eleanor (1325–1375), married Peter IV of Aragon, and was the mother of John I of Aragon and Martin the Humane. Beatrice (1326–1365) their third daughter, married Rupert II, Elector Palatine, and they had Rupert of Germany. Their fourth surviving child, Euphemia (1330–1359), was regent for her brother Frederick IV of Sicily from 1355 to 1357. Like her sister Constance, Euphemia never married.
Following their four daughters, Elizabeth gave birth to Louis on 4 February 1338. Louis became the heir to Peter II, his father. After successfully producing a male heir, Elizabeth and Peter II had Frederick, later Frederick IV of Sicily and his brother Louis's successor. Peter II and Elizabeth had three more children together; Violante, who was born in 1334, died young, John (1342–22 June 1353) and Blanche (1342–1373), who married John, Count of Ampurias. Of their ten children, five daughters and two sons survived into adulthood.
The death of Frederick III in 1337 sparked the explosion of Sicilian tensions, created from the confluence of strain of political uncertainty, a bad economy and unstable power imbalance between the divided feudal class. The death of her father-in-law began the solo reign of Peter II as King of Sicily.
King Frederick's reign, which ended in 1337 with the succession of his son Peter, was a tale of two types. The early years were an attempt at reconstruction from the fighting with Naples that ended in 1302. Frederick wanted to integrate the people of Sicily and unite them into a true Kingdom of Sicily. He attempted to do this by drawing on the people's hate of the Angevins and was largely successful. During this reconstruction process, the Sicilians saw improvement in their fortunes, both culturally and commercially, until around 1312. As invasions by the Angevins increased during the 1310s, Sicily was ravaged. Siding with the Ghibellines resulted in a loss of Guelph trading partners in northern Italy. It appears that most Sicilians were ambivalent to the Guelph/Ghibelline conflict, which made Frederick's decision seem unreasonable. Various food crises also occurred between 1311 and 1335. After 1321, the economy was in ruins. Constant port blockades by Robert of Naples hurt Sicily further, and by 1325 its economy was destroyed. Frederick's government became increasingly hated and powerless. The economic burden of constantly being at war had taken its toll on the population. The king had also dispensed the majority of his personal wealth to churches and hospitals, so there was nothing left to give barons or ecclesiastical leaders. If all of this was not bad enough, eruptions of Mount Etna in 1329 and 1333 signaled to Sicilians that God was punishing them for Frederick's sins. Once the decline started, it just got worse and worse. When Frederick died in 1337, civil war broke out in Sicily, with the barons feuding for control of the island. Peter II and Elizabeth were left with a kingdom that went from a high point in the early part of Frederick's reign, to a low point at his death when Sicily was in shambles. The decisions made by Frederick may have protected Sicily from the Angevins, but it came at a cost that would be a common theme when Elizabeth became queen.
As it was easy to influence Peter II, Sicily would have been much more negatively impacted by his reign if it were not for Elizabeth. In the struggles between the feuding groups, Elizabeth sided with the Palizzi, who won the favour of the king over Chiaramonte. Further from their home in Messina, the Aragonese interest warred the Angevins warred in Greece. With her mother-in-law, Eleanora of Naples, Elizabeth worked to support mediation and reconciliation between the two feuding houses. Although very limited in actual power, Elizabeth used her influences to impact the governance of Sicily.
With the death of her husband Peter II in August 1342, Elizabeth lost the influence over the political management of the Kingdom of Sicily. At Elizabeth's insistence, Louis, her four-year-old son, was crowned King of Sicily, ensuring his rightful place on the throne. Peter II's brother, Duke John, acted as regent for the first six years of the young king's reign. During this time, Elizabeth kept a power balance with her brother-in-law. When Duke John died of plague in 1348, Elizabeth became the regent for ten-year-old Louis. Elizabeth's regency lasted from 1348, until her death. Her daughter Constance took over as regent for Louis.
It is unclear when exactly Elizabeth died. Some sources suggest that she died between 1349 and 1350, while others date it later to 1352. She is buried in Messina in St. Francis. Her last son, King Frederick IV (d. 1377), is buried next to her.
Although little information remains on Elizabeth of Carinthia, Queen of Sicily, what little is known makes it clear that she worked to positively impact the decisions of those around her. Her influence over her husband Peter II ensured that the Kingdom of Sicily remain intact. Later, her delicate negotiations with Duke John, her brother-in-law and regent of Louis, helped to maintain the Kingdom of Sicily. Elizabeth's agency ensured that her children did inherit the Sicilian throne. Elizabeth's action exhibits how queens were able to exert influence, not just as wives, but as mothers of the future generation.
