  • Pontificate: 12 years (1655-1667)
  • College of Cardinals: approximately 70 electors
  • Need for pope capable of resolving tensions with France

Situation of the Church (1667):

  • France: Louis XIV at height of power, aggressive foreign policy
  • Spain: declining but still influential
  • Jansenism: ongoing controversy in France
  • Portugal: seeking independence from Spain, ecclesiastical reorganization needed
  • Turks: continuing threat to Venetian Crete

The Conclave

Dates: May 22 – June 20, 1667

Duration: Approximately one month

Political Alignments:

  • French faction: supporting candidates favorable to Louis XIV
  • Spanish faction: supporting candidates favorable to Charles II
  • Independent cardinals: seeking compromise candidate

Why Rospigliosi Won:

  1. French support: King Louis XIV of France instructed the French faction to turn their support to Rospigliosi 
  2. Spanish acceptability: Believed also that he would appease the Spanish faction of Charles II due to the fact that he had once been the Apostolic Nuncio to Spain 
  3. Curial experience: Fifteen years as nuncio and cardinal secretary of state
  4. Personal reputation: Known for learning, charity, and diplomatic skill
  5. Moderate temperament: Seen as capable of healing rift between Paris and Rome 

Election (June 20, 1667): 

  • Elected on the twentieth day of the conclave
  • Received all but two votes (voted for another; Cardinal Neri Corsini voted for Cardinal Flavio Chigi) 
  • Chose name: Clement IX
  • Indicative of a policy of appeasement 

Comment on Election:

When asked about Rospigliosi becoming pope, Cardinal Francesco Albizzi said: “Urban turned the Holy See into a bank; Innocent into a brothel; Alexander into a tavern; this one will make a playhouse of it.” Albizzi also alluded to Rospigliosi’s passion for music and said, “He will emasculate the Sacred College by giving the hat to all the castrated singers in Europe!” 

Coronation (June 26, 1667): 

  • Crowned by the protodeacon, Cardinal Rinaldo d’Este
  • Age at coronation: 67 years old

Possession of St. John Lateran (July 3, 1667): 

  • Traditional ceremony taking possession of the cathedral of Rome

PONTIFICATE (1667-1669) – THE AMIABLE POPE

Character and Governing Style

Personal Piety and Charity:

  • “He was the idol of the Romans, not so much for his erudition and application to business, as for his extreme charity and his affability towards great and small” 
  • Two days each week he occupied a confessional in St. Peter’s Basilica and heard anyone who wished to confess to him 
  • He frequently visited the hospitals 
  • He was lavish in his alms to the poor 

Anti-Nepotism:

  • In an age of nepotism, he did little or nothing to advance or enrich his family 
  • He almost wholly broke with the traditional nepotism, and assigned his relatives only modest and moderately profitable offices 
  • In his aversion to notoriety, he refused to permit his name to be placed on the buildings erected during his reign 

Economic Reforms:

  • He increased the goodwill of his subjects by buying off the monopolist who had secured the macinato, or privilege of selling grain 
  • As his predecessor had collected the money for the purpose, Clement IX had the decree published in the name of Alexander VII 
  • By strict economy he brought the papal finances into good order 

Work Habits:

  • Applied himself diligently to business
  • But remembered more for charity than administration

The Clementine Peace (Pax Clementina)

Background – Jansenist Controversy:

  • Jansenism: theological movement emphasizing grace, predestination, limited redemption
  • Cornelius Jansen’s Augustinus (1640) condemned by Urban VIII, Innocent X, Alexander VII
  • Formulary controversy: requirement that clergy sign condemnation of five propositions from Jansen
  • A minority of Jansenists, including four bishops and the nuns of Port-Royal, still refused subscription 

Negotiations:

  • Clement’s policy of appeasement materialized in an agreement called the Peace of Clement IX (January 1669) 
  • Through discussions between French Foreign Minister Hugues de Lionne and the papal nuncio, Clement was prevailed upon to accept (January 19, 1669) the recalcitrant bishops’ subscription 
  • This occurred despite it being hedged around with qualifications to which he had to turn a blind eye 
  • It was in fact a victory for Louis XIV, who considered the Jansenists a threat to the unity of his kingdom 

Outcome:

  • Procured a lull in the storm, which, unfortunately, owing to the insincerity of the sectaries, was but temporary 
  • It suspended persecution of the Jansenists 
  • The Peace lasted from 1669 to 1679 
  • “It soon became apparent at Rome that the ‘Peace’ was being interpreted as a sign of the church’s weakness in the face of French pressure” 

Assessment:

  • By a mild compromise, he procured temporary peace 
  • Demonstrated his commitment to reconciliation
  • But unresolved issues would resurface

Mediation in European Wars

War of Devolution (1667-1668):

  • Louis XIV invaded Spanish Netherlands, claiming they had “devolved” to his wife (Maria Theresa of Spain) through a local inheritance law
  • France vs. Spain
  • England, Dutch Republic, and Sweden formed Triple Alliance to check French expansion

Peace of Aachen (May 2, 1668): 

  • Clement IX brought about, as arbiter, the Peace of Aix-la-Chapelle between France and Spain 
  • He gravely admonished Louis XIV against the aggressive career upon which he was setting forth 
  • However, he was no match diplomatically for Hugues de Lionne, Mazarin’s brilliant successor as French foreign minister 
  • The peace left in France’s hands the fortified towns in Flanders it wanted 
  • While it flattered him to play a role in the negotiations, the diplomatic advantage was with France 

Admonition to Louis XIV:

  • Clement gravely admonished Louis XIV against the aggressive career upon which he was setting forth 
  • Though unable to stop French expansion, he registered papal concern

Reorganization of the Church in Portugal

Context:

  • Portugal had achieved independence from Spain (1640, recognized 1668)
  • Ecclesiastical situation confused during decades of war
  • Numerous vacant sees needed filling

Clement’s Action:

  • He reorganized the Church in Portugal, after that nation had achieved its independence from Spain 
  • When Spain recognized (February 1668) the independence of Portugal, he felt able to settle the confused ecclesiastical situation in that country by at last filling the numerous vacant sees 

Relations with France

Removal of Humiliating Inscription:

  • A humiliating inscription admitting the guilt of the papal soldiers which Louis XIV had forced Alexander VII to set up in Rome was removed 
  • But Clement in return had to allow the French crown a free hand in church appointments 
  • Demonstrated the continuing pressure of Gallicanism on the papacy

Defense of Crete Against the Turks

The Siege of Candia:

  • Venetian fortress of Candia (modern Heraklion) on the island of Crete
  • Had been under siege by the Ottoman Turks for twenty years (1648-1669)
  • Last major Christian outpost in the eastern Mediterranean

Clement’s Efforts:

  • He was able to furnish material aid to Venice for the defence of Crete, then besieged by the Turks 
  • He attempted to strengthen Venetian defenses against the Turks on the island of Crete 
  • However, he was unable to get wider support for this cause 
  • Had the European powers listened to his exhortations, that important island would not have been lost to Christendom 
  • Louis XIV refused Clement’s plea for aid to Crete 

The Fall:

  • The Cretan seaport city of Candia, after a siege of 20 years, fell on September 5, 1669 
  • Followed by the submission of the island to the Turks

Canonizations and Beatifications

Beatification (April 15, 1668):

Creation of Cardinals

Three Consistories: 

  • Elevated 12 new cardinals in three consistories
  • This included Emilio Bonaventura Altieri, who would succeed him as Pope Clement X 
  • On November 29, just ten days before he died, he named seven new cardinals and announced one whom he had reserved “in pectore” 

PATRONAGE OF THE ARTS

Collaboration with Gian Lorenzo Bernini

Lifelong Collaboration:

  • Clement IX was a committed patron of the arts during his short term as pope 
  • He embellished the city of Rome through his engagement with the celebrated artist Gian Lorenzo Bernini, with whom he had collaborated before ascending to the papacy 
  • Bernini created stage designs for performances of operas and plays written by the young Rospigliosi 

Major Commissions:

  1. Angels of Ponte Sant’Angelo: 
    • Bernini designed the angels for the bridge leading to Castel Sant’Angelo
    • One of Rome’s most famous artistic landmarks
  2. Colonnade of St. Peter’s Basilica: 
    • Bernini continued work on the great piazza
    • The colonnade embracing the faithful was completed during Clement’s reign
  3. Santa Maria Maggiore Expansions:
    • A papal medal by Girolamo Lucenti, created in 1669, commemorated Clement’s expansion of the basilica of Santa Maria Maggiore, which the pontiff also entrusted to Bernini 

Modesty in Patronage:

  • Somewhat unusually for popes of the era, Clement IX did not have his name displayed on monuments he built 
  • Consistent with his aversion to notoriety 

Opera and Theater

Carnival Celebrations (1668):

  • For the Carnival celebrations of 1668, commissioned Antonio Maria Abbatini of the Sistine Chapel Choir to set to music his free Italian translation of a Spanish religious drama La Baltasara 
  • The production had sets designed by Bernini 

First Public Opera House:

  • He opened the first public opera house in Rome 
  • Despite Cardinal Albizzi’s prediction, he did not make the College of Cardinals a “playhouse”

Portrait Medals

Medallic Art:

  • A portrait medallion of Clement IX, attributed to Girolamo Lucenti (c. 1627-1698), survives in the Harvard Art Museums 
  • Gilt bronze in high relief, 30.8 cm diameter
  • Depicts the pope in profile: high forehead, slightly hooked nose, curly hair extending to collar, mustache, medium-length beard
  • The image bears a strong resemblance to a papal medal by Lucenti created in 1669 to commemorate Clement’s expansion of Santa Maria Maggiore 

LAST YEARS AND DEATH

Illness and Anxiety

Health Decline (Autumn 1669):

  • Clement IX was seriously ill throughout the autumn in 1669 with a hernia and kidney stones 
  • Despite his illness and his anxiety over the Turkish advances in Crete, he travelled on a pilgrimage to the seven Roman basilicas 
  • That night, he had a severe apoplexy (stroke) 

The News from Crete:

  • At the end of October 1669, Clement IX fell ill after receiving news that the Venetian fortress of Candia in Crete had surrendered to the Turks 
  • The news of its fall, after a gallant resistance of twenty years, hastened the pope’s death 
  • He died, allegedly of a broken heart 

Final Acts (November 29, 1669):

  • Just ten days before he died, he named seven new cardinals and announced one whom he had reserved “in pectore” 
  • The dying pope intended to create a “faction” for his nephew with which to use in the next conclave to defend his policies 

Death

December 9, 1669: 

  • Died at age 69
  • Location: Rome, Papal States
  • Cause: complications from hernia, kidney stones, stroke, possibly brought on by grief over the fall of Candia 
  • Clement IX died mourning the Christians slain at Candia 

Last Words:

  • Not recorded precisely
  • Likely prayers, commendation of soul

Posthumous Allegation:

  • Following his death, the Florentine agent in Rome, writing to Grand Duke Ferdinando II de’ Medici a few days later, accused the late Clement IX of having hidden the fact that he was epileptic, which would have, according to the canon law in place at the time, disqualified him from exercising any ecclesiastical functions 
  • However, this has never been proven 

Reaction to Death

Rome’s Mourning:

  • “The death of the beloved pontiff was long lamented by the Romans, who considered him, if not the greatest, at least the most amiable of the popes”

Burial and Monument

Clement’s Wishes:

  • He ordered his remains to be buried under the pavement of Santa Maria Maggiore 
  • With the simple inscription: Clementis IX, Cineres (“The ashes of Clement IX”) 
  • Consistent with his humility and aversion to self-promotion

Monument by Clement X:

  • His successor, Clement X, erected in his honour the sumptuous monument which stands at the right-hand side of the nave, near the door of Santa Maria Maggiore 
  • Ironically, the humble pope who refused to put his name on buildings received one of Rome’s more elaborate papal tombs

  • Unanimously mourned

Final Judgment

Pope Clement IX, Giulio Rospigliosi, reigned for only two and a half years—one of the shorter pontificates of the 17th century. Yet in that brief time, he left an indelible mark on the Church, on Rome, and on the hearts of the Roman people. He stands as the amiable pope, a man whose charity, humility, and kindness made him beloved in an age of absolutism and ambition.

His greatest political achievement was the Peace of Aachen, mediating between France and Spain and ending the War of Devolution. Though diplomatically outmatched by the brilliant de Lionne, he at least brought the parties to the table and secured a temporary peace. He also reorganized the Church in Portugal after its independence from Spain, filling vacant sees and regularizing ecclesiastical life.

His most complex legacy is the Clementine Peace regarding Jansenism. By accepting a compromise that turned a blind eye to qualifications in the bishops’ subscription, he procured a temporary lull in the storm. It was a victory for Louis XIV and French policy, and it would soon become apparent that the peace was being interpreted as a sign of the Church’s weakness in the face of French pressure. Yet for a decade, the controversy subsided—a breathing space that might have led to permanent reconciliation had the parties been more sincere.

His greatest sorrow was the fall of Candia. He furnished material aid to Venice, called on European powers to help, and watched as they refused. Louis XIV, the Most Christian King, would not lift a finger to save the last Christian outpost in the eastern Mediterranean. When Candia fell, Clement’s health, already fragile, collapsed. He died of a broken heart—a martyr to the cause of Christendom.

His most enduring legacy may be his personal example. In an age of nepotism, he did little or nothing to advance his family. In an age of self-promotion, he refused to put his name on buildings. In an age of distance between pope and people, he heard confessions in St. Peter’s twice a week, visited hospitals, and was lavish in alms to the poor. He was the idol of the Romans not for his learning or his business acumen, but for his charity and his affability.

His artistic legacy is significant. He collaborated with Bernini on the angels of Ponte Sant’Angelo and the colonnade of St. Peter’s. He opened the first public opera house in Rome. He wrote libretti that are credited with creating comic opera as an individual form. He was a patron of Poussin. He was the last pope to be a significant creative artist in his own right.

His canonizations gave the Church Rose of Lima (the first American saint), Mary Magdalene de’ Pazzi, and Peter of Alcántara—a Peruvian, an Italian, and a Spaniard, reflecting the universality of the Church he served.

His simplicity was remarkable. He ordered his remains buried under the pavement of Santa Maria Maggiore with only the simple inscription “Ashes of Clement IX.” His successor gave him a magnificent monument instead—the irony of a humble pope receiving posthumous grandeur.

In the history of the papacy, Clement IX occupies a unique place: not among the great popes who changed the course of history, but among the beloved popes who changed hearts. He proved that a pope could be both holy and amiable, both principled and kind, both a diplomat and a pastor. He died mourned by all, and his memory remained long in Rome.

Comparison with Innocent XII is instructive. Innocent XII abolished nepotism by law; Clement IX practiced anti-nepotism by inclination. Innocent XII reformed the Curia; Clement IX reformed hearts. Innocent XII was austere; Clement IX was amiable. Both, in their different ways, prepared the Church for the reforms of the 18th century.

Comparison with Clement XI is also revealing. Clement XI reigned 20 years, faced the Chinese Rites controversy, issued Unigenitus, and died in political defeat. Clement IX reigned 2.5 years, faced Jansenism and Turkish invasion, and died of grief. Both were learned, both were pious, but Clement IX was beloved in a way few popes have been.

The story of his death is perhaps the most revealing. When Candia fell, he fell. His heart was so invested in the cause of Christendom, in the defense of the faith, in the suffering of Christians under Turkish rule, that their defeat was his death. It was a death worthy of a pastor—dying for his sheep, even sheep he had never seen.

His epitaph might be: “He loved the poor, heard confessions, enriched the Church with saints and the city with beauty, and died of grief when Christendom was wounded. The amiable pope, the poet pope, the pope of broken heart.”

Giulio Rospigliosi of Pistoia was a man of many gifts: scholar, poet, librettist, diplomat, cardinal, pope. But above all, he was a man of heart—a heart open to God in prayer, to the poor in charity, to the sick in compassion, to the whole Church in pastoral care, and finally to the suffering of Christians far away in Crete. That heart broke on December 9, 1669, and Rome mourned.

Clement IX: the pope who proved that holiness and amiability are not opposites, that charity is the greatest art, and that a broken heart can be the most eloquent witness to love.
