Guillaume d'Estouteville, (c. 1412–1483) was a French aristocrat of royal blood who became a leading bishop and cardinal. He held a number of Church offices simultaneously. He conducted the reexamination of the case of Jeanne d'Arc and exonerated her of the charges against her. He reformed the Statutes of the University of Paris. In Rome he became one of the most influential members of the Curia, as the official Protector of France in church business. Pope Sixtus IV appointed him Chamberlain of the Holy Roman Church (Camerlengo). His great wealth allowed him to be a generous patron of the arts, especially in the building and adornment of churches.
D'Estouteville was born ca. 1412 in either Valmont or Estouteville-Écalles in the Duchy of Normandy, a member of the most powerful family in the region. His father, Jean d'Estouteville, Sieur de Vallemont and Grand Chamberlain of France, had fought at Agincourt, was captured, and spent twenty years as a prisoner of war. His mother was Marguerite d'Harcourt, the daughter of Catherine de Bourbon, the sister of Jeanne de Bourbon who was the wife of King Charles V of France. Guillaume had an elder brother Louis, who became Grand Bouteiller of France. As the custom was, the younger brother was destined for a career in the Church. The family lost a great deal of property and income as a result of the English occupation of Normandy after the Battle of Agincourt. A collateral ancestor (uncle?), also called Guillaume d'Estouteville, had been Bishop of Évreux (1375–1376) at the age of twenty, Bishop of Auxerre (1376–1382), and Bishop of Lisieux (1382–1415).
It was first said by Alfonso Chacon, and often repeated thereafter, that Guillaume became a Benedictine monk at the Saint-Martin-des-Champs Priory in Paris, where he soon became prior. Both of these statements, however, have been shown to be mistaken. Documentary evidence written at Saint-Martin in 1500 shows that he was a secular priest, and that he was Administrator of Saint-Martin. Chacon also states that d'Estouteville was Doctor Decretorum (Doctor of Canon Law), but various papal documents of Pope Eugenius IV, in particular one of 1435, calls him a Papal Notary, a relative of the Kings of France, a Master of Arts, and of Canon Law, having passed rigorous examinations. Henri Denifle states that d'Estouteville's degree in Canon Law did not come from the University of Paris. Guillaume did possess a Canonry in the Church of Évreux, and in 1432 he was Canon in Lyon as well. In 1433 he became Canon in Angers.
The Bishop of Angers, Hardouin du Brueil, died on 18 January 1439. Guillaume D'Estouteville, who was ambitious for the post, immediately rushed to Rome and obtained bulls from Pope Eugene IV on 20 February naming him to the bishopric. On 28 February the Canons of the Cathedral Chapter met and duly elected Jean Michel of Beauvais, a Councillor of Rene of Anjou and Canon of Rouen and of Angers, though d'Estouteville received several votes in the election. The election of Jean Michel was confirmed by the Vicars-General of the Archbishop of Tours. The bulls which d'Estouteville had obtained in Rome were presented to the Chapter of Angers on 24 April by d'Estouteville's procurator, but the majority of the Chapter rejected his pretensions. In the meantime Bishop Jean Michel was sitting as Bishop of Angers in the Council of Basel. King Charles VII of France was angered at the interference of the Pope in French church affairs and threatened, in support of the Gallican church, to apply the Pragmatic Sanction and exclude the Pope's bulls. Pope Eugene escaped from the danger by giving d'Estouteville the bishopric of Digne in the Alpes-de-Haute-Provence, a suffragan of Embrun. He renounced his claim on Angers on 27 October 1447.
On 18 April 1440, he was named the Apostolic Administrator of the Diocese of Mirepoix; his commission was revoked upon the appointment of a new bishop on 17 May 1441. He never visited Mirepoix, but he did collect a year's income.
A few months after the affair of Angers, Guillaume d'Estouteville was named a cardinal priest in the consistory of 18 December 1439 by Pope Eugene IV, and assigned the titular church of San Martino ai Monti. The Cardinal's hat probably softened the disappointment of losing the bishopric of Angers. Pope Eugene probably derived a bit of satisfaction at granting a red hat to a member of the French royalty without the request or consent of the King.
He was consecrated a bishop in January 1440. In 1440 he was briefly administrator of the diocese of Conserans (St. Lizier) The following year he was additionally appointed as Administrator of the Dioceses of Béziers and Nîmes.
In 1443, Cardinal d'Estouteville was appointed Archpriest of the Basilica Liberiana (Santa Maria Maggiore) by Pope Eugene IV, in succession to Cardinal Niccolò Albergati, who died on 9 May 1443. He held the position for life. In March 1451 Pope Nicholas V granted a new set of Statutes to the Canons of the Basilica, which emphasized the decisive power that the Archpriest had over the physical structure of the church and its property. In his Testament d'Estouteville left funds for the refurbishment and redecoration of the Chapel of S. Michele e S. Pietro in Vincoli, and for the building of the Chapel of S. Antonio.
On 7 January 1450 D'Estouteville was appointed Administrator of the Diocese of Lodève. He served in this office for three years, before being appointed as bishop of the Diocese of Saint-Jean-de-Maurienne in Savoy. He was Bishop of Maurienne from 26 January 1453 to 20 April 1453, though he continued to act as Administrator of the diocese for the rest of his life. In April 1453 he was released from his obligation as Bishop of Maurienne and appointed Archbishop of Rouen by Nicholas V. The Canons of Rouen protested the violation of their rights, and Pope Nicholas granted them an Indult on 16 November promising them that, on the death of Guillaume d'Estouteville, they could elect whomever they wished. D'Estouteville took possession of the diocese of Rouen on 30 April 1453 through a Procurator, Bishop Louis d'Harcourt of Narbonne.
On 13 August 1451 Cardinal d'Estouteville was sent to France as legate by Pope Nicholas V, on the instigation of the Duc de Bourbon, to make peace between King Charles VII of France and England; at the same time Cardinal Nicholas of Cusa was sent to England on the same mission. Both failed.
He undertook at the instigation of the Inquisitor General Jean Brehal an ex officio revision of the trial of Joan of Arc. He afterwards reformed the statutes of the University of Paris, issuing his decree on 1 June 1452. He shortened the course leading to the Doctorate in theology from fifteen to fourteen years, and he removed the requirement that Doctors of Medicine be in holy orders. He then went to preside over the assembly of clergy which met at Bourges in July and August 1452 to discuss the observation of the Pragmatic Sanction. He finally returned to Rome on 3 January 1453, where he passed almost all the rest of his life.
D'Estouteville, appointed Legate to the King of France, departed from Rome for France on 16 May 1454, with permission to be outside the Curia for six months; he returned to Rome on 12 September 1455 after sixteen months absence. His official mission was to attempt to persuade Charles VII to join in yet another crusade, the one that Nicholas V had tried to launch on 30 September 1453, following the Fall of Constantinople.
On his return, he built as his residence the Palazzo Apollinare to the west of the Church of S. Agostino and adjacent to the Church of S. Apollinare.
D'Estouteville participated in the papal conclave of 4–10 March 1447 that elected Pope Nicholas V. He was absent from Rome, however, during the sede vacante of 24 March–8 April 1455, prior to the election of Pope Calixtus III. D'Estouteville took part in the Conclave of 6–19 August 1458 and was a candidate for the papacy in the Conclave; he was able to command six votes out of the nineteen participants, but he was defeated by Cardinal Aeneas Sylvius Piccolomini of Siena, who chose the name Pope Pius II.
On 20 February 1456 he was one of the cardinals who subscribed the bull of Pope Calixtus III which created Rodrigo Borgia a cardinal.
In 1458 Cardinal d'Estouteville was asked by the Teutonic Knights to be their Protector at the Roman Curia, an honor and office which he accepted. D'Estouteville also was cardinal protector of the Augustinian Hermits. In January 1459 he accompanied Pope Pius II in his journey to Mantua to meet with the princes of Europe to arrange for a crusade against the Ottoman Turks.
He became Cardinal Bishop of Porto-Santa Rufina on 19 March 1459. He was named the Cardinal-Bishop of Ostia on 26 October 1461, and became the Dean of the College of Cardinals after the death of Cardinal Bessarion on 18 November 1472.
On January 11, 1468 the Cardinal was elected Chamberlain of the College of Cardinals for a one-year term. This was a burdensome office, requiring the holder to see to it that monies due to the College of Cardinals from all sources, including the Pope, were collected, and to see to it that they were disbursed to the cardinals who were in the Roman Curia.
Campaign for the Papacy
Pope Paul died on 26 July 1471, and Cardinal d'Estouteville immediately began campaigning openly for the papacy. He wrote to Galeazzo Maria Sforza, Duke of Milan, seeking his support and that of the four cardinals who were 'Friends of the Prince'. But there were other candidates, notably Cardinal Bessarion, who was being supported by Venice. Eighteen cardinals, out of the twenty-five living cardinals, attended the Conclave, which began on 6 August 1471. In the second Scrutiny, on August 9, Cardinal Francesco della Rovere was elected with thirteen of the eighteen votes. D'Estouteville had received six votes. Della Rovere chose as his papal name Sixtus IV.
On 25 August 1471, Cardinal d'Estouteville, availing himself of the traditional privilege of the Bishops of Ostia, consecrated Cardinal Francesco della Rovere, O.F.M.Conv., who had been elected Pope Sixtus IV, a bishop. The Coronation took place on the same day on the front steps of the Vatican Basilica by Cardinal Rodrigo Borja, the senior Cardinal Deacon.
The Cardinal also owed a vineyard near the Porta S. Maria del Popolo. On 15 May 1472 he gave a luncheon there in honor of Cardinal Rodrigo de Borja, who was leaving Rome on a mission to Catalonia and Spain. Earlier that day, the seals of the Chamberlain of the Sacred College were transferred from Cardinal Borjia, who was Chamberlain for the year, to Cardinal d'Estouteville, who was to fill out the rest of his term. On 12 October 1472, he was appointed in Consistory to be Legate in France.
He was appointed Camerlengo of the Holy Roman Church (S.R.E. Camerarius) by Pope Sixtus IV in 1477, in succession to Cardinal Latino Orsini, who had died on 11 August 1477. D'Estouteville held the position until his death; he was the last non-Italian cardinal to hold the office for nearly five hundred years, until Jean-Marie Villot in 1970.
Patron of the Arts
Rouen (the episcopal palace), Mont Saint-Michel (the choir of the church), Pontoise (the episcopal palace), and the Château de Gaillon owe the construction of many buildings to his initiative. In his capacity as Bishop of Ostia d'Estouteville had the walls of the town restored, and built the Cathedral of Saint Aurea. In Velletri he rebuilt the episcopal palace. The cardinal also financed the rebuilding of the Church of St. Agostino in Rome. He then had the remains of Saint Monica, the mother of St. Augustine, brought from Ostia Antica for entombment in a marble sarcophagus he had built for them. His name prominently embellishes the façade. He is also credited with building the Church of S. Agostino at Cori and the Church of S. Agostino at Tolentino. He was a generous donor of sacred articles to the Church of San Luigi dei Francesi in March 1482.
D'Estouteville died in Rome on 22 January 1483. His remains were buried in the Basilica of Sant'Agostino. His heart, however, was removed, as was the custom, and taken to be placed in the tomb he had built for himself in the Cathedral of Rouen. A bust of him was placed at the entrance to the sacristy of S. Agostino, with an inscription dated 1865.
With his mistress, Girolama Togli, Guillaume d'Estouteville had five children, including Girolamo Tuttavilla (Tuttavilla is an Italian version of Estouteville), a son Agostino, a daughter Margherita, and a daughter Giulia.

Cardinal d'Estouteville performed a number of episcopal consecrations in Rome as part of his duties in the Roman Curia. He has the distinction of being the origin of the oldest extant, traceable episcopal lineage within the Catholic Church and the most numerous non-Rebiban lineage. This refers to the ongoing effort to trace the links from one bishop to his consecrator, to his consecrator, etc., all the way back to the Apostles. Thus far, the research has only been able to establish connections back to the mid-fifteenth century.
In the case of d'Estouteville, he consecrated Pope Sixtus IV; therefore, all bishops consecrated by Sixtus IV are in the "d'Estouteville Line". Sixtus IV consecrated Pope Julius II, and thus all bishops consecrated by Julius II are in the "d'Estouteville Line". Julius II consecrated Raffaele Riario, who consecrated Pope Leo X, and therefore all bishops consecrated by Leo X are in the "d'Estouteville Line". The major problem is that there is no evidence as to who consecrated d'Estouteville himself. The fact that there is a "d'Estouteville Line", therefore, is an accident of missing information.
