Constance of Sicily

Constance was born in 1248 in Catania, on the eastern coast of Sicily, into the most powerful and most embattled dynasty in thirteenth century Europe ^[1]. Her father was Manfred, a son of the Holy Roman Emperor Frederick II, and her mother was Beatrice of Savoy, Manfred's first wife. Anyone asking who was Constance of Sicily must begin with this parentage, because her entire adult life was shaped by the claims and misfortunes of the Hohenstaufen line into which she was born ^[2].

Her grandfather Frederick II had ruled Sicily as the jewel of his empire, and his court there mixed Latin, Greek, and Arabic learning in a way that had few parallels in the medieval West ^[3]. Frederick died in 1250, when Constance was a small child, and the papacy, which had fought him for decades, set out to destroy his heirs. Manfred first governed Sicily on behalf of his half brother Conrad IV and then, after rumors spread of Conrad's young son's death, took the crown for himself at Palermo in 1258 ^[1].

Constance grew up as the daughter of a king under permanent papal excommunication. Successive popes treated Manfred as a usurper and searched for a foreign champion willing to invade his kingdom. That search would eventually bring Charles of Anjou, brother of King Louis IX of France, into Italian affairs, with consequences that defined the rest of Constance's life ^[2].

In June 1262 Constance was married at Montpellier to the Infante Peter, heir to King James I of Aragon ^[1]. The match was a deliberate piece of statecraft. Manfred gained a friendly Iberian power at a moment when papal hostility was hardening, and the Aragonese royal house acquired a potential claim to the wealthy kingdom of Sicily. The papacy understood the marriage in exactly those terms and objected to it, since it tied the ambitious Crown of Aragon to the excommunicated Hohenstaufen ^[2].

Disaster followed within four years. Charles of Anjou, invested with the Sicilian crown by Pope Clement IV, marched south and met Manfred's army at Benevento on 26 February 1266. Manfred was killed on the field, and because he died excommunicate he was denied Christian burial, an indignity that Dante later memorialized in the Purgatorio, where Manfred asks the poet to carry news of his fate to his beautiful daughter, Constance ^[4]. Two years later the last legitimate male of the dynasty, Constance's young cousin Conradin, invaded Italy to recover the kingdom, was defeated at Tagliacozzo, and was publicly beheaded in Naples in October 1268 ^[2].

With Conradin's execution, Constance became the principal living heir of the Hohenstaufen claim to Sicily. Her mother in law reportedly found the situation ominous, but at the Aragonese court the exiled Sicilians who gathered around Constance kept the claim alive. Among the facts about Constance of Sicily that mattered most to contemporaries, this inheritance stood first: she was, in the eyes of her father's former subjects, the rightful queen of a stolen kingdom ^[1].

Peter succeeded his father in 1276, and Constance was crowned queen of Aragon alongside him at Zaragoza ^[5]. Their marriage produced six children who survived to adulthood, and the list reads like a map of Mediterranean politics: Alfonso III of Aragon, James II of Aragon, Frederick III of Sicily, Isabella, who married King Denis of Portugal and was later canonized as Saint Elizabeth of Portugal, Yolanda, who married Robert of Naples, and Peter ^[1].

At the Aragonese court Constance served as the living link between her husband and the Sicilian exile community. Men such as John of Procida, a physician and diplomat who had served her father, entered Peter's service and worked for years to prepare the recovery of Sicily in her name ^[2]. Chroniclers of the Crown of Aragon presented Peter's later intervention in the island not as conquest but as the vindication of his wife's rights, a framing the king himself used consistently ^[5].

Meanwhile Charles of Anjou governed Sicily harshly from Naples, taxing the island heavily and staffing its administration with French and Provencal officials. Resentment accumulated for sixteen years. Any biography of Constance of Sicily has to reckon with the paradox of these years: a queen with no army and no territory of her own whose name nonetheless anchored an entire political movement across the sea ^[2].

On 30 March 1282, at the hour of vespers on Easter Monday, an altercation outside the church of the Holy Spirit in Palermo ignited a massacre of the French garrison and settlers. The revolt, known ever since as the Sicilian Vespers, spread across the island within weeks and destroyed Angevin authority there ^[6]. The rebels first attempted to organize themselves as free communes, but facing the certainty of Charles's counterattack they sent envoys to Peter III, asking him to take the crown in right of his wife ^[2].

Peter, who had assembled a fleet on the North African coast, landed at Trapani in August 1282 and was received at Palermo as king. The following year Constance herself crossed to Sicily with her younger children, and the island's parliament recognized her son James as heir to the Sicilian throne. For the first time since childhood, Constance stood in her father's kingdom, now as its queen ^[1].

The cost was heavy. Pope Martin IV excommunicated Peter, declared his Aragonese crown forfeit, and preached a crusade against him, which France attempted to execute in the failed invasion of 1285. When Peter died in November of that year, the dynastic settlement he left divided his realms: Aragon went to Alfonso, and Sicily to James, with Constance named to head the council governing the island during the transition ^[2]. Among the achievements of Constance of Sicily, her role in these years was the most concrete, since she acted as regent in Sicily for the young James, working with John of Procida as chancellor and the formidable admiral Roger of Lauria, whose naval victories kept the Angevins at bay ^[6].

The war Constance had helped to win outlasted her patience for it. After Alfonso III died childless in 1291, James left Sicily to take the Aragonese crown, and in 1295 he made peace with the papacy and the Angevins in the Treaty of Anagni, agreeing to relinquish Sicily. The Sicilians refused to be handed back and instead crowned Constance's third son, Frederick, as their king in 1296, splitting the family the treaty was meant to reconcile ^[2].

Constance took part in the diplomacy surrounding the settlement and traveled to Rome in 1297, where her daughter Yolanda was married to Robert, a grandson of the Charles of Anjou who had killed Manfred. The wedding joined the two houses whose feud had consumed her whole life ^[2]. She then withdrew from politics and returned to Barcelona.

In her final years she lived in religious retirement, associated with the Franciscan community of the city, and contemporary tradition records her as having taken the habit as a nun ^[1]. She died in Barcelona on 9 April 1302, a few months before the Peace of Caltabellotta finally ended the twenty year War of the Sicilian Vespers by confirming her son Frederick on the Sicilian throne. She was buried in the Franciscan convent of Barcelona, and her remains were later transferred to Barcelona Cathedral ^[7].

Constance transmitted a kingdom. Through her, the crown of Sicily passed from the Hohenstaufen emperors to the House of Barcelona, and her descendants ruled the island for generations, tying Sicily into the Catalan and Aragonese commercial world of the late Middle Ages ^[3]. The kings of Aragon and later of Spain traced their Sicilian title to her marriage, which made a 1262 wedding in Montpellier one of the durable facts of Mediterranean political geography.

Her literary afterlife is unusually secure. In the third canto of the Purgatorio, Dante places Manfred among the late repentant and has him speak of his daughter as the mother of the honor of Sicily and Aragon, a reference to her sons James and Frederick ^[4]. Few medieval queens received such a monument from such a poet, and the lines have kept her name before readers for seven centuries.

Historians treat her less as an actor in her own right than as the indispensable hinge of the Vespers crisis, though her regency in Sicily during the mid 1280s shows a capable and trusted political figure, not merely a vessel for a claim ^[6]. The essential facts of the Constance of Sicily biography, heiress, queen, regent, and finally nun, describe a life spent carrying the weight of a dynasty that had been destroyed before she turned twenty, and carrying it to an outcome her father could not have imagined ^[2].
