Petronilla (29 June[1]/11 August[2] 1136 – 15 October 1173), whose name is also spelledPetronila orPetronella (Aragonese:Peyronela orPayronella,[3] andCatalan:Peronella), wasQueen of Aragon (1137–1164[4]) from theabdication of her father,Ramiro II, in 1137 until her own abdication in 1164. After her abdication she acted as regent during the minority of her sonAlfonso II of Aragon (1164–1173). She was the last ruling member of theJiménez dynasty in theKingdom of Aragon, and by marriage toRamon Berenguer IV, Count of Barcelona brought theHouse of Barcelona to the throne of Aragon, uniting the Kingdom of Aragon with theCounty of Barcelona to create theCrown of Aragon.
Born in August 1136, Petronilla was the daughter of Ramiro II of Aragon and Agnes of Aquitaine.[5] She came to the throne through special circumstances. Her father,Ramiro, wasbishop of Barbastro-Roda when his brother,Alfonso I, died childless in 1134. Alfonso left the kingdom to the Knights Templar, the Hospitallers, and the Knights of the Holy Sepulchre, but his decision was not respected.[5] The aristocracy ofNavarre elected a king of their own, restoring their independence, and the nobility of Aragon raised Ramiro to the throne.[5]Pope Innocent II rejected this election, seeking to affirm Alfonso I's final will.[5] Despite the lack of papal approval, King Ramiro the Monk, as he is known, marriedAgnes of Aquitaine in 1135.[5]
Petronilla's marriage was a very important matter of state. The nobility had rejected the proposition ofAlfonso VII of Castile to arrange a marriage between Petronilla and his sonSancho and to educate her at his court. When she was just a little over one year old, Petronilla was betrothed inBarbastro on 11 August 1137 toRaymond Berengar IV, Count of Barcelona, who was twenty-three years her senior.[6]
AtEl Castellar on 13 November 1137, Ramiro abdicated, transferred authority to Ramon Berenguer, and returned to monastic life.[6] Ramon Berenger ruled the kingdom using the title of "Prince of the Aragonese" (princeps Aragonensis).
In August 1150, when Petronilla was fourteen, the betrothal was ratified at a wedding ceremony held in the city ofLleida.[7] Petronilla consummated her marriage to Ramon Berenguer in the early part of 1151, when she reached the age of 15. The marriage produced five children: Peter (1152–57),Raymond Berengar (1157–96),Peter (1158–81),Dulce (1160–98), andSancho (1161–1223). While she was pregnant with the first, on 4 April 1152, she wrote up a will bequeathing her kingdom to her husband in case she did not survive childbirth.[8] Even before the death of her father Ramiro II, Petronilla was using the title Queen of Aragon in her will, written in 1152.[9]
While her husband was away in Provence (1156–57), where he was regent (since 1144) for the young CountRaymond Berengar II, Queen Petronilla remained in Barcelona. Accounting records show her moving between there andVilamajor andSant Celoni while presiding over the court in Raymond Berengar's absence.[10]
After her husband's death in 1162, Petronilla received the prosperousCounty of Besalú and theVall de Ribes for life. As a widow, she was the only ruler of Aragon for the next two years.

Even after the death of her husband Ramon Berenguer IV, the titles of Petronilla were Queen of Aragon andCountess of Barcelona in the document about her abdication in 1164.[11] Her eldest son was seven years old when, on 18 June 1164 (Actum est hoc in Barchinona XIIII kalendas julii anno Dominice incarnationis M C LXIIII), Petronilla abdicated the throne of Aragon and passed it to him. When Raymond Berenguer inherited the throne from his mother, he changed his name to Alfonso out of deference to the Aragonese. The second son, named Peter, then changed his name to Raymond Berenguer. Her son and heir was only seven years old when she abdicated in his favor, and so she continued to rule after her abdication, this time acting as his regent during his minority.
Petronilla died inBarcelona in October 1173 and was buried atBarcelona Cathedral; her tomb has been lost. After her death, Besalú and Vall de Ribes reverted to the direct domain of the count of Barcelona, her son Alfonso, who by 1174 had bestowed Besalú on his wife,Sancha.[12] In the Ribes, the local bailiff, Ramon, had carved out for himself "a virtually independent administrative authority" there. He had conducted an inventory for Petronilla after Raymond Berenguer's death, and his son and namesake was in power in 1198.[13]
In 1410, after the death ofKing Martin without living legitimate descendants, theHouse of Barcelona became extinct in the legitimate male line. Two years later,Ferdinand I was enthroned per theCompromise of Caspe. Although Ferdinand triumphed mainly for political and military reasons, the theoretical basis of his candidacy was inheritance in the female line, for which Queen Petronilla served as the precedent. He was Martin's closest legitimate male relative, but related through a woman. His chief opponent, CountJames II of Urgell, was related to Martin more distantly, but in the male line. In Catalonia there were indications that women were forbidden to hold comital office, but in Aragon there was no legislation on the subject. In both places there were a few cases of women who had passed on their right to their sons, most importantly Petronilla.
There is a long debate whether Petronilla was the true ruler of Aragon. Some claim that Ramiro II gave the kingdom of Aragon to his son-in-law and that the presence of Petronilla was secondary. According toJerónimo de Zurita, there was a clause in the pact with Ramon Berenguer stating that if Petronilla died, Aragon would pass to the children of Ramon Berenguer through a future second marriage. In any case, there is insufficient documentation to make a completely conclusive statement about the question and the Compromise of Caspe confirmed the legitimacy of female transmission.[14]
TheSpanish Navyscrew frigatePetronila,in commission from 1858 to 1863, was named for Petronilla of Aragon.[15]
