Pope Clement VII (Italian: Papa Clemente VII; Latin: Clemens VII) (26 May 1478 – 25 September 1534), born Giulio de' Medici, was head of the Catholic Church and ruler of the Papal States from 19 November 1523 to his death on 25 September 1534. “The most unfortunate of the popes,” Clement VII's reign was marked by a rapid succession of political, military, and religious struggles—many long in the making—which had far-reaching consequences for Christianity and world politics.
Elected in 1523 at the end of the Italian Renaissance, Clement came to the papacy with a high reputation as a statesman. He had served with distinction as chief advisor to Pope Leo X (1513–1521), Pope Adrian VI (1522–1523), and commendably as gran maestro of Florence (1519–1523). Assuming leadership at a time of crisis, with the Protestant Reformation spreading; the Church nearing bankruptcy; and large, foreign armies invading Italy, Clement initially tried to unite Christendom by making peace among the many Christian leaders then at odds. He later attempted to liberate Italy from foreign occupation, believing that it threatened the Church's freedom.
The complex political situation of the 1520s thwarted Clement's efforts. Inheriting daunting challenges, including Martin Luther’s Protestant Reformation in Northern Europe; a vast power struggle in Italy between Europe’s two most powerful kings, Holy Roman Emperor Charles V and Francis I of France, each of whom demanded that the Pope choose a side; and Turkish invasions of Eastern Europe led by Suleiman the Magnificent, Clement's problems were exacerbated by King Henry VIII of England’s contentious divorce, resulting in England breaking away from the Catholic Church; and in 1527, souring relations with Emperor Charles V, leading to the violent Sack of Rome, during which Clement was imprisoned. After escaping confinement in the Castel Sant'Angelo, Clement—with few economic, military, or political options remaining—compromised the Church's and Italy's independence by allying with his former jailor, Charles V.
In contrast to his tortured Papacy, Clement was personally respectable and devout, possessing a “dignified propriety of character,” “great acquirements both theological and scientific,” as well as “extraordinary address and penetration—Clement VII, in serener times, might have administered the Papal power with high reputation and enviable prosperity. But with all of his profound insight into the political affairs of Europe, Clement does not seem to have comprehended the altered position of the Pope” in relation to Europe's emerging nation-states and Protestantism.
Clement left a significant cultural legacy in the Medici tradition. He commissioned iconic artworks by Raphael, Benvenuto Cellini, and Michelangelo, including the latter's ‘’The Last Judgment’’ in the Sistine Capel. In matters of science, Clement is best known for approving, in 1533, Nicolaus Copernicus’s theory that the Earth revolves around the Sun—99 years before Galileo Galilei’s heresy trial for similar ideas. Ecclesiastically, Clement is remembered for orders protecting Jews from the Inquisition, approving the Capuchin Franciscan Order, and securing the island of Malta for the Knights of Malta.
Giulio de' Medici's life began under tragic circumstances. On 26 April 1478—exactly one month before his birth—his father, Giuliano de Medici (brother of Lorenzo the Magnificent) was murdered in the Florence Cathedral by enemies of his family, in what is now known as “The Pazzi Conspiracy”. He was born illegitimately on 26 May 1478, in Florence; the exact identity of his mother remains unknown, although a plurality of scholars contend that it was Fioretta Gorini, the daughter of a university professor. Giulio spent the first seven years of life with his godfather, the architect Antonio da Sangallo the Elder.
Thereafter, Lorenzo the Magnificent raised him as one of his own sons, alongside his children Giovanni (the future Pope Leo X), Piero, and Giuliano. Educated at the Palazzo Medici in Florence by humanists like Angelo Poliziano, and alongside prodigies like Michelangelo, Giulio became an accomplished musician. In personality he was reputed to be shy, and in physical appearance, handsome.
Giulio's natural inclination was for the clergy, but his illegitimacy barred him from high-ranking positions in the Church. So Lorenzo the Magnificent helped him carve out a career as a soldier. He was enrolled in the Knights of Rhodes, but also became Grand Prior of Capua. In 1492, when Lorenzo the Magnificent died and Giovanni de' Medici assumed his duties as a cardinal, Giulio became more involved in Church affairs. He studied canon law at the University of Pisa, and accompanied Giovanni to the conclave of 1492, where Rodrigo Borgia was elected Pope Alexander VI.
Following the misfortunes of Lorenzo the Magnificent's firstborn son, Piero the Unfortunate, the Medici were expelled from Florence in 1494. Over the next six years, Cardinal Giovanni and Giulio wandered throughout Europe together—twice getting arrested (first in Ulm, Germany, and later in Rouen, France). Each time Piero the Unfortunate bailed them out. In 1500, both returned to Italy and concentrated their efforts on re-establishing their family in Florence. Both were present at the Battle of Ravenna in 1512, where Cardinal Giovanni was captured by the French but Giulio escaped; this led to Giulio becoming an emissary to Pope Julius II. That same year, with the assistance of Pope Julius and the Spanish troops of Ferdinand of Aragon, the Medici retook control of Florence.
Paternity of Alessandro de' Medici
In 1510, while the Medici were living near Rome, a servant in their household—identified in documents as Simonetta da Collevecchio—became pregnant, ultimately giving birth to a son, Alessandro de' Medici. Nicknamed “il Moro” (“the Moor”) due to his dark complexion, Alessandro was officially recognized as the illegitimate son of Lorenzo II de Medici, but at the time and to this day, various scholars suggest that Alessandro was the illegitimate son of Giulio de' Medici. The truth of his lineage remains unknown and debated.
Regardless of his paternity, throughout Alessandro's brief life, Giulio—as Pope Clement VII—showed him great favoritism, elevating Alessandro over Ippolito de Medici as Florence's first hereditary monarch, despite the latter's comparable qualifications.
Under Pope Leo X
Giulio de' Medici appeared on the world stage in March 1513, at the age of 35, when his cousin Giovanni de' Medici was elected Pope, taking the name Leo X. Pope Leo X reigned until his death on 1 December 1521.
“Learned, clever, respectable, and industrious,” Giulio de’ Medici's reputation and responsibilities grew at a rapid pace, unusual even for the Renaissance. Within three months of Leo X's election, he was named Archbishop of Florence. Later that autumn, all barriers to his attaining the Church's highest offices were removed by a papal dispensation declaring his birth legitimate. It stated that his parents had been betrothed per sponsalia de presenti, (i.e. "wed according to the word of those present.”) Whether or not this was true, it allowed Leo X to create him cardinal during the first papal consistory on 23 September 1513. On 29 September, he was appointed Cardinal Deacon of Santa Maria in Dominica—a position that had been vacated by the Pope.
Cardinal Giulio's reputation during the reign of Leo X is recorded by contemporary Marco Minio, the Venetian ambassador to the Papal Court, who wrote in a letter to the Venetian Senate in 1519: "Cardinal de' Medici, the Pope’s cardinal nephew, who is not legitimate, has great power with the Pope; he is a man of great competence and great authority; he resides with the Pope, and does nothing of importance without first consulting him. But he is returning to Florence to govern the city.”
While Cardinal Giulio wasn't officially appointed Vice-Chancellor of the Church (second-in-command) until 9 March 1517, in practice Leo X governed in partnership with his cousin from the beginning. Initially, his duties centered primarily on administering Church affairs in Florence and conducting international relations. In January 1514, King Henry VIII of England appointed him Cardinal protector of England. The following year, King Francis I of France nominated him to become Archbishop of Narbonne, and in 1516 named him cardinal protector of France. In a scenario typical of Cardinal Giulio's independent-minded statesmanship, the respective kings of England and France, recognizing a conflict of interest in Giulio protecting both countries simultaneously, brought pressure to bear on him to resign his other protectorship; to their dismay, he refused.
Cardinal Giulio’s foreign policy was shaped by the idea of “la libertà d'Italia,” which aimed to free Italy and the Church from French and Imperial domination. This became clear in 1521, when a personal rivalry between King Francis I and Holy Roman Emperor Charles V boiled over into war in northern Italy. Francis I expected Giulio, France's cardinal protector, to support him; but Giulio perceived Francis as threatening the Church's independence—particularly the latter's control of Lombardy, and his use of the Concordat of Bologna to control the Church in France. At the time, the Church wanted Emperor Charles V to combat Lutheranism, then growing in Germany. So Cardinal Giulio negotiated an alliance on behalf of the Church, to support the Holy Roman Empire against France. That autumn, Giulio helped lead a victorious Imperial-Papal army over the French in Milan and Lombardy. While his strategy of shifting alliances to liberate the Church and Italy from foreign domination proved disastrous during his reign as Pope Clement VII, during the reign of Leo X it skillfully maintained a balance of power among the competing international factions seeking to influence the Church.
Cardinal Giulio's other endeavors on behalf of Pope Leo X were similarly successful, such that "he had the credit of being the prime mover of papal policy throughout the whole of Leo’s pontificate." In 1513, he was member of the Fifth Lateran Council, assigned the task of healing the schism caused by conciliarism. In 1515, his “most significant act of ecclesiastical government” regulated prophetic preaching in the manner of Girolamo Savonarola. He later organized and presided over the Florentine Synod of 1517, where he became the first member of the Church to implement the reforms recommended by the Fifth Lateran Council. These included prohibiting priests from carrying arms, frequenting taverns, and dancing provocatively – while urging them to attend weekly confession. Similarly, Cardinal Giulio's artistic patronage was admired (e.g., his commissioning Raphael’s Transfiguration and Michelangelo’s Medici Chapel, among other works), particularly for what goldsmith Benvenuto Cellini later called its "excellent taste".
Gran Maestro of Florence
Cardinal Giulio governed Florence between 1519 and 1523, following the death of its civic ruler, Lorenzo II de Medici, in 1519. There “he was permitted to assume almost autocratic control of State affairs,” and “did very much to place public interests upon a firm and practical basis.”  U.S. President John Adams later characterized Giulio's administration of Florence as "very successful and frugal." Adams chronicles the cardinal as having "reduced the business of the magistrates, elections, customs of office, and the mode of expenditure of public money, in such a manner that it produced a great and universal joy among the citizens."
On the death of Pope Leo X in 1521, Adams writes there was a "ready inclination in all of the principal citizens [of Florence], and a universal desire among the people, to maintain the state in the hands of the Cardinal de’ Medici; and all this felicity arose from his good government, which since the death of the Duke Lorenzo, had been universally agreeable."
Under Pope Adrian VI
When Pope Leo X died on 1 December 1521, Cardinal Giulio was “widely expected to succeed him”—but instead, during the conclave of 1522, the College of Cardinals elected a compromise candidate, Adrian VI of the Netherlands. Of why this happened, historian Paul Strathern writes, “it was common knowledge that [Cardinal Giulio] had been Leo X’s most able adviser, as well as manager of the pope’s financial affairs. The fact that Leo X had blithely ignored his cousin’s advice, on so many occasions, was widely seen as being responsible for the plight of the papacy—not the influence of Cardinal Giulio de’ Medici. On the contrary, Cardinal Giulio appeared to be everything that Leo X was not: he was handsome, thoughtful, saturnine and gifted with good taste. Despite this, many remained steadfast in their opposition to his candidacy.”
In conclave, Cardinal Giulio controlled the largest voting bloc, but his enemies forced the election to a stalemate. Among them were Cardinal Francesco Soderini, a Florentine whose family had lost a power struggle to the Medici “and held a grudge”; Cardinal Pompeo Colonna, a Roman nobleman who wanted to become Pope himself; and a group of French cardinals who “were unwilling to forget Leo X’s treachery to their King.”
Realizing that his candidacy was in jeopardy, “Cardinal Giulio now chose to make an astute tactical move. He declared modestly that he was unworthy of such high office; instead, he suggested the little-known Flemish scholar Cardinal Adrian Dedel, an ascetic and deeply spiritual man who had been tutor to the Holy Roman Emperor Charles V. Cardinal Giulio was sure that Cardinal Dedel would be rejected—on the grounds of his obscurity, his lack of political expertise and the fact that he was not Italian. The selfless suggestion that had been made by Cardinal Giulio de’ Medici would then demonstrate to all that he was in fact the ideal candidate. But this move backfired badly, Cardinal Giulio's bluff was called and Cardinal Adrian Dedel was elected as Pope Adrian VI.”
During his 20-month papacy, Adrian VI “seemed to set great store by Cardinal Medici's opinions... And all the other cardinals were kept distinctly at arm's-length.” In this way, Cardinal Giulio “wielded formidable influence” throughout Adrian's reign. Splitting time between the Palazzo Medici in Florence and the Palazzo della Cancelleria in Rome, Cardinal Giulio “lived there as a generous Medici was expected to live, a patron of artists and musicians, a protector of the poor, a lavish host.” 
Assassination Plot of 1522
In 1522, rumors began to swirl that Cardinal Giulio—lacking legitimate successors to rule Florence—planned to abdicate rule of the city and "leave the government freely in the people." When it became clear that these rumors were untrue, a faction of mostly elite Florentines hatched a plot to assassinate him and then install their own government under his "great adversary", Cardinal Francesco Soderini. Soderini encouraged the plot, exhorting both Adrian and Francis I of France to strike against Giulio and invade his allies in Sicily. This did not happen. Instead of breaking with Giulio, Adrian had Cardinal Soderini imprisoned. Afterward, the principal conspirators were "declared rebels", and some were "apprehended and beheaded; by which means Giulio was again secured [as leader of Florence]."
Election as Pope, 1523
Following Adrian VI's death on 14 September 1523, Medici overcame the opposition of the French king and finally succeeded in being elected Pope Clement VII in the next conclave (19 November 1523).
Pope Leo brought to the papal throne a high reputation for political ability and possessed in fact all the accomplishments of a wily diplomat. But his contemporaries considered him worldly and indifferent to the perceived dangers of the Protestant Reformation.
At his accession, Clement VII sent the Archbishop of Capua, Nikolaus von Schönberg, to the Kings of France, Spain, and England, in order to bring the Italian War to an end. An early report from the Protonotary Marino Ascanio Caracciolo to the Emperor records: "As the Turks threaten to conquer Christian states, it seems to him that it is his first duty as Pope to bring about a general peace of all Christian princes, and he begs him (the Emperor), as the firstborn son of the Church, to aid him in this pious work." But the pope's attempt failed.
Continental and Medici politics
Francis I of France's conquest of Milan in 1524, during his Italian campaign of 1524–1525, prompted the Pope to quit the Imperial–Spanish side and to ally himself with other Italian princes, including the Republic of Venice, and France in January 1525. This treaty granted the definitive acquisition of Parma and Piacenza for the Papal States, the rule of Medici over Florence and the free passage of the French troops to Naples. This policy in itself was sound and patriotic, but Clement VII's zeal soon cooled; by his want of foresight and unseasonable economy, he laid himself open to an attack from the turbulent Roman barons, which obliged him to invoke the mediation of the emperor, Charles V. One month later, Francis I was crushed and imprisoned in the Battle of Pavia, and Clement VII went deeper in his former engagements with Charles V, signing an alliance with the viceroy of Naples.
But deeply concerned about Imperial arrogance, he was to pick up with France again when Francis I was freed after the Treaty of Madrid (1526): the Pope entered into the League of Cognac together with France, Venice, and Francesco II Sforza of Milan. Clement VII issued an invective against Charles V, who in reply defined him a "wolf" instead of a "shepherd", menacing the summoning of a council about the Lutheran question.
Like his cousin Pope Leo X, Clement was considered too generous to his Medici relatives, draining the Vatican treasuries. This included the assignment of positions all the way up to Cardinal, lands, titles, and money. These actions prompted reform measures after Clement's death to help prevent such excessive nepotism.
In his bull "Intra Arcana" Clement VII gave a grant of permissions and privileges to Charles V and the Spanish Empire, which included patronage power[vague] over their colonies in the Americas.
Sack of Rome

The Pope's wavering politics also caused the rise of the Imperial party inside the Curia: Cardinal Pompeo Colonna's soldiers pillaged Vatican Hill and gained control of the whole of Rome in his name. The humiliated Pope promised therefore to bring the Papal States to the Imperial side again. But soon after, Colonna left the siege and went to Naples, not keeping his promises and dismissing the Cardinal from his charge.[contradictory] From this point on, Clement VII could do nothing but follow the fate of the French party to the end.[ambiguous]
Soon he found himself alone in Italy too, as Alfonso d'Este, duke of Ferrara, had supplied artillery to the Imperial army, causing the League Army to keep a distance behind the horde of Landsknechts led by Charles III, Duke of Bourbon and Georg von Frundsberg, allowing them to reach Rome without harm.[dubious ]
Charles of Bourbon died while mounting a ladder during the short siege and his starving troops, unpaid and left without a guide, felt free to ravage Rome from 6 May 1527. The many incidents of murder, rape, and vandalism that followed ended the splendours of Renaissance Rome forever. Clement VII, who had displayed no more resolution in his military than in his political conduct, was shortly afterwards (6 June) obliged to surrender himself together with the Castel Sant'Angelo, where he had taken refuge. He agreed to pay a ransom of 400,000 ducati in exchange for his life; conditions included the cession of Parma, Piacenza, Civitavecchia, and Modena to the Holy Roman Empire. (Only the last could be occupied in fact.) At the same time, Venice took advantage of his situation to capture Cervia and Ravenna while Sigismondo Malatesta returned in Rimini.
Clement was kept as a prisoner in Castel Sant'Angelo for six months. After having bought off some Imperial officers, he escaped disguised as a peddler and took shelter in Orvieto and then in Viterbo. He came back to a depopulated and devastated Rome only in October 1528.
Meanwhile, in Florence, Republican enemies of the Medici took advantage of the chaos to again expel the Pope's family from the city.
In June 1529 the warring parties signed the Peace of Barcelona. The Papal States regained some cities and Charles V agreed to restore the Medici to power in Florence. In 1530, after an eleven-month siege, the Tuscan city capitulated and Clement VII installed his illegitimate nephew Alessandro as duke. Subsequently, the Pope followed a policy of subservience to the emperor, endeavouring on the one hand to induce him to act with severity against the Lutherans in Germany and on the other to avoid his demands for a general council.
During his half-year imprisonment in 1527, Clement VII grew a full beard as a sign of mourning for the sack of Rome. This was in contradiction to Catholic canon law, which required priests to be clean-shaven but had as precedent the beard Pope Julius II wore for nine months in 1511–12 as a sign of mourning for the papal city of Bologna.
Unlike Julius II, however, Clement kept his beard until his death in 1534. His example in wearing a beard was followed by his successor, Paul III, and indeed by 24 popes after him, down to Innocent XII, who died in 1700. Clement was thus the unintentional originator of a fashion that lasted well over a century.
In 1532, Clement VII took possession of Ancona, which definitively lost its freedom and became part of the Papal States, ending hundreds of years when the Republic of Ancona was an important maritime power.
By the late 1520s, King Henry VIII wanted to have his marriage to Charles's aunt Catherine of Aragon annulled. The couple's sons died in infancy, threatening the future of the House of Tudor, although Henry did have a daughter, Mary Tudor. Henry claimed that this lack of a male heir was because his marriage was "blighted in the eyes of God". Catherine had been his brother's widow, but the marriage had been childless, so the marriage was not against Old Testament law, which forbids such unions only if the brother had children. Moreover, Pope Julius II had given a dispensation to allow the wedding. Henry now argued that this had been wrong and that his marriage had never been valid. In 1527 Henry asked Clement to annul the marriage, but the Pope, possibly acting under pressure from Catherine's nephew, Holy Roman Emperor Charles V, whose effective prisoner he was, refused. According to Catholic teaching, a validly contracted marriage is indivisible until death, and thus the pope cannot annul a marriage on the basis of an impediment previously dispensed. Many people close to Henry wished simply to ignore Clement, but in October 1530 a meeting of clergy and lawyers advised that the English Parliament could not empower the Archbishop of Canterbury to act against the Pope's prohibition. In Parliament, Bishop John Fisher was the Pope's champion.
Henry subsequently underwent a marriage ceremony with Anne Boleyn, in either late 1532 or early 1533. The marriage was made easier by the death of the Archbishop of Canterbury William Warham, a stalwart friend of the Pope, after which Henry persuaded Clement to appoint Thomas Cranmer, a friend of the Boleyn family, as his successor. The Pope granted the papal bulls necessary for Cranmer's promotion to Canterbury, and also demanded that Cranmer take the customary oath of allegiance to the pope before his consecration. Laws made under Henry already declared that bishops would be consecrated even without papal approval. Cranmer was consecrated, while declaring beforehand that he did not agree with the oath he would take. Cranmer was prepared to grant the annulment of the marriage to Catherine as Henry required. The Pope responded to the marriage by excommunicating both Henry and Cranmer from the Catholic Church.
Consequently, in England, in the same year, the Act of Conditional Restraint of Annates transferred the taxes on ecclesiastical income from the Pope to the Crown. The Peter's Pence Act outlawed the annual payment by landowners of one penny to the Pope. This act also reiterated that England had "no superior under God, but only your Grace" and that Henry's "imperial crown" had been diminished by the Pope's "unreasonable and uncharitable usurpations and exactions". Ultimately, in 1534, Henry led the English Parliament to pass the Act of Supremacy that established the independent Church of England and broke from the Catholic Church.
A discerning patron, Clement VII personally commissioned Michelangelo’s The Last Judgment for the Sistine Chapel, Raphael’s masterpiece The Transfiguration, as well as celebrated works by Benvenuto Cellini, Niccolo Machiavelli, and Parmigianino, among others. Artistic trends of the era are sometimes called the “Clementine style,” and notable for their virtuosity. Clement is also remembered for having been Cellini's patron.
In 1533, Johann Widmanstetter (or John Widmanstad), a secretary of Clement's, explained the Copernican system to him and two cardinals. Clement was so pleased that he gave Widmanstetter a valuable gift.
Towards the end of his life, Clement VII once more gave indications of leaning towards a French alliance. His plans to ally the House of Medici with the French royal family bore fruit in the betrothal of the Pope's niece, Catherine de' Medici, to Henri, the son of King Francis I. Before setting out, Clement issued a Bull on 3 September 1533 giving instructions as to what was to be done in the event that he died outside Rome. In September 1533 he set out for France to solemnize the marriage. The marriage took place in Marseille on 28 October 1533. On 7 November in Marseille, Clement created four new cardinals, all four of them French. He also held separate, private meetings with Francis I and Charles V.
Illness and death
Clement returned to Rome on 10 December 1533, complaining of stomach problems and showing a fever. This was not a new illness. He had been so ill at the beginning of August that year that Cardinal Agostino Trivulzio wrote to King Francis that the Pope's doctors had begun to fear that he was in danger of dying. On 23 September 1533, Clement wrote a long letter of farewell to Charles V. He also ordered, just a few days before his death, Michelangelo's painting of The Last Judgment in the Sistine Chapel. He died on 25 September 1534, having lived 56 years and four months and reigned for 10 years, 10 months, and 7 days.
It has been said that he died from eating poisonous mushrooms, but the symptoms and length of illness do not fit this hypothesis. Nor do they account for the effects on his illness of two sea voyages within two months. In the words of his biographer Emmanuel Rodocanachi, "In accordance with the custom of those times, people attributed his death to poison." His body was interred in Saint Peter's Basilica and later transferred to a permanent tomb in the Choir of Santa Maria sopra Minerva in Rome.
Character and assessments
Clement was renowned for his intelligence and counsel, but maligned for his inability to take timely and decisive action. Historian G.F. Young writes, “he spoke with equal knowledge of his subject whether that were philosophy and theology, or mechanics and hydraulic architecture. In all affairs he displayed an extraordinary acuteness; the most perplexing questions were unravelled, the most difficult circumstances penetrated to the very bottom, by his extreme sagacity. No man could debate a point with more address.”  Historian Paul Strathern writes, “his inner life was illuminated by an unwavering faith;” he was also in “surprisingly close contact with the ideals [of Renaissance humanism], and even more surprisingly was deeply sympathetic to them.”  For example, “Clement VII had no difficulty in accepting Copernicus’s heliocentric idea, and appeared to see no challenge to his faith in its implications; his Renaissance humanism was open to such progressive theories.”  Of Clement's other qualities, Strathern writes “he had inherited his murdered father’s good looks, though these tended to lapse into a dark scowl rather than a smile. He also inherited something of his great-grandfather Cosimo de’ Medici’s skill with accounts, as well as a strong inclination to his legendary caution, making the new pope hesitant when it came to taking important decisions; and unlike his cousin Leo X, he possessed a deep understanding of art.” 
Of Clement's limitations, historian Francesco Guicciardini writes, “although he had a most capable intelligence and marvelous knowledge of world affairs, he lacked the corresponding resolution and execution... He remained almost always in suspension and ambiguous when he was faced with deciding those things that from afar he had many times foreseen, considered, and almost revealed.”  Strathern writes that Clement was “a man of almost icy self-control, but in him the Medici trait of self-contained caution had deepened into a flaw... If anything, Clement VII had too much understanding – he could always see both sides of any particular argument. This had made him an excellent close adviser to his cousin Leo X, but hampered his ability to take matters into his own hands.”  The Catholic Encyclopedia notes that while his “private life was free from reproach and he had many excellent impulses... despite good intention, all qualities of heroism and greatness must emphatically be denied him.”
Clement VII's papacy is generally regarded as one of history's most tumultuous; opinions of Clement himself are often nuanced. For example, Clement's contemporary Francesco Vettori writes that he “endured a great labor to become, from a great and respected cardinal, a small and little-esteemed pope”, but also that “if one considers the lives of previous popes one may truly say that, for more than a hundred years, no better man than Clement VII sat upon the Throne. Nevertheless, it was in his day that the disaster took place while these others, who were filled with all vices, lived and died in felicity—as the world sees it. Neither should we seek to question the lord, our God, who will punish—or not punish–in what manner and in what time it pleases him.’”
The disasters of Clement’s pontificate—the Sack of Rome and the English Reformation—are regarded as turning points in the histories of Catholicism, Europe, and the Renaissance. Modern historian Kenneth Gouwens writes, “Clement’s failures must be viewed above all in the context of major changes in the dynamics of European politics. As warfare on the Italian peninsula intensified in the mid-1520s, the imperative of autonomy [for the Catholic Church and Italy] required enormous financial outlays to field standing armies. Political survival perforce eclipsed ecclesiastical reform as a short-term goal, and the costs of war necessitated the curtailment of expenditure on culture. Clement pursued policies consistent with those of his illustrious predecessors Julius II and Leo X; but in the 1520s, those policies could but fail… Reform of the Church, to which his successors would turn, required resources and concerted secular support that the second Medici pope was unable to muster.”
Regarding Clement's struggle to liberate Italy and the Catholic Church from foreign domination, historian Fred Dotolo writes that “one might see in his papacy a vigorous defense of papal rights against the growth of monarchial power, a diplomatic and even pastoral struggle to retain the ancient division within Christendom of the priestly and kingly offices. Should the new monarchs of the early modern period reduce the papacy to a mere appendage of secular authority, religious issues would become little more than state policy… Clement VII attempted to restrain the expansion of royal power and maintain the independence of Rome and of papal prerogatives.”
In a final analysis of Clement's papacy, historian E.R. Chamberlin writes, “in all but his personal attributes, Clement VII was a protagonist in a Greek tragedy, the victim called upon to endure the results of actions committed long before. Each temporal claim of his predecessors had entangled the Papacy just a little more in the lethal game of politics, even while each moral debasement divorced it just a little more from the vast body of Christians from whom ultimately it drew its strength.” More charitably, modern historian James Grubb writes, “indeed, at a certain point it is difficult to see how he might have fared much better, given the obstacles he faced. Certainly his predecessors since the end of the Schism had experienced their share of opposition, but did any have to fight on so many fronts as Clement, and against such overwhelming odds? At one time or another he battled the Holy Roman Empire (now fuelled by precious metals from America), the French, the Turks, rival Italian powers, fractious forces within the papal states, and entrenched interests within the Curia itself. That the precious liberta d’Italia (freedom from outside domination) should have been lost irrevocably seems more an inevitability than a product of Clement’s particular failings. He tried his utmost...”

In realtà, anche in questo - che fu il più significativo atto di governo ecclesiastico di Giulio - gli interessi familiari si legarono strettamente alla restaurazione delle istituzioni della Chiesa: il savonarolismo fu colpito sia per la carica antiecclesiastica, che ormai esprimeva, sia per quella antimedicea.”

- Medici does not appear as Bishop either in F. Ughelli, Italia sacra II (ed. N. Colet) (Venice 1717), p. 37; or in Pius Gams, Series episcoporum (1873), p. 676. Considering the time span, some eight weeks, it is more likely that he was Administrator. On 3 March, the day that Medici resigned, Cardinal Grassis (who had been Bishop of Bologna) was named Administrator of Bologna.
