Francesco de’ Pazzi - banker

Medici rival at heart of Pazzi Conspiracy

The moment at which Giuliano de' Medici is killed,
imagined by 19th century painter Stefano Ussi

The banker Francesco de’ Pazzi, a central figure in the Pazzi Conspiracy that sought to overthrow the Medici family as the rulers of Florence, was born on this day in 1444.

De’ Pazzi killed Giuliano de’ Medici, stabbing him to death during mass at the Florence Duomo as the conspirators attempted to seize control.

But Giuliano’s brother, Lorenzo the Magnificent, with whom he was joint ruler, escaped with only minor wounds.

Simultaneously, other conspirators rode into the Piazza della Signoria declaring themselves the liberators of the city. But the people of Florence were loyal to the Medicis and attacked them.

Within hours, despite Lorenzo appealing for calm, an angry mob determined to exact revenge had hunted down and killed more than 30 conspirators or suspected conspirators, including Francesco.

One of nine children born to Antonio de’ Pazzi and Nicolosa, daughter of Alessandro degli Alessandri, Francesco was an important figure in the Pazzi banking business, having been appointed papal treasurer.

This in itself made for a tense relationship between the Medici and the Pazzi, even though they were actually related thanks to the marriage of Guglielmo de' Pazzi and Bianca de' Medici, Lorenzo’s elder sister.

The administration of the papal finances was a coveted prize for any banking family and Pope Sixtus IV’s decision to take responsibility away from the Medici Bank in favour of the Pazzi antagonised Lorenzo in particular.

Sixtus IV, from a poor bacground originally, was determined to enrich both his own Della Rovere family and their cousins, the Riario family. He had designs on the rich Florentine territories for the benefit of his nephews, including the nobleman Girolamo Riario, and also to finance the expensive works undertaken by him in Rome.

The rift between Rome and the Medicis occurred when Galeazzo Maria Sforza, the Duke of Milan, changed his mind about selling the town of Imola, which occupied a strategic position on the trade route between Florence and Venice, to Lorenzo de’ Medici in favour of a deal with Sixtus IV, provided that Sixtus agreed to the marriage of his daughter, Caterina Sforza, to Girolamo Riario.

Lorenzo, as Sforza’s banker, refused to finance the deal, not wishing to see an extension of the papal states, at which Sixtus turned to the Pazzis and handed the contract for the papal treasury to them.

There were suspicions that the Pazzi Conspiracy was actually conceived in Rome but the Pazzi had reasons of their own to turn against the Medici, not least the decision of Lorenzo to introduce a law that prevented a considerable sum of money flowing into the Pazzi coffers with the death of Giovanni Borromei, the very wealthy father in law of Giovanni de’ Pazzi, another of Francesco’s brothers.

Borromei’s fortune should have passed to Beatrice Borromei, Giovanni de’ Pazzi’s wife. But Lorenzo changed the law so that daughters could not inherit in the absence of any brothers, and that in those circumstances any legacy would pass instead to male cousins.

A further source of friction between Lorenzo and the Pazzi was his appointment of Lorenzo's brother-in-law Rinaldo Orsini as Archbishop of Florence in succession to the late Pietro Riario in 1474. The candidates overlooked included Francesco Salviati, a relative of the Pazzi family and friend of Francesco.

Whatever its origins, it is generally accepted that the chief conspirators in the Pazzi Conspiracy were Girolamo Riario, Francesco de' Pazzi and Francesco Salviati, the trio who attacked Lorenzo and Giuliano in the Florence duomo, the magnificent Cathedral of Santa Maria del Fiore, on the morning of April 26, 1478.

Giuliano was assassinated by Francesco de' Pazzi together with Bernardo Bandini di Baroncelli, suffering a sword wound to the head as well as being stabbed 19 times.  Lorenzo was attacked by two of Jacopo Pazzi's men, but managed to escape.

Salviati then took a number of Jacopo Pazzi's men to the Piazza della Signoria hoping to be received by the Florentine populace as liberators. Instead, they were attacked. Along with Francesco de' Pazzi and several others, Salviati was hanged from the windows of the Palazzo Vecchio.

More than 30 suspected conspirators were caught and killed within hours of the attack and over the course of the next eight months some 50 more were captured and executed, including Bandini dei Baroncelli, who had escaped to Constantinople but was arrested and returned, to be hanged from a window of the Palazzo del Capitano del Popolo while still dressed in Turkish clothing. 

Jacopo de' Pazzi, head of the family, escaped from Florence but was caught and brought back to be tortured and then hanged from the Palazzo della Signoria next to the decomposing corpse of Salviati. 

All other members of the Pazzi family were banished from Florence, and their lands and property confiscated. The family name was erased from public registers, while all buildings and streets carrying it were renamed. Anyone named Pazzi had to take a new name; anyone married to a Pazzi was barred from public office.

Travel tip:

The Piazza della Signoria has been the focal point of the city of Florence since the 14th century. Overlooked by the imposing Palazzo Vecchio, it was the scene of the triumphant return of the Medici family in 1530, three and a half decades after they had been driven from the city by the supporters of the fanatical priest, Girolamo Savonarola. The controversial cleric's famous bonfires of the vanities were built in the middle of the square.  The piazza della Signoria contains several important sculptures and statues, including a copy of Michelangelo's David - the original is in the Galleria dell'Accademia - Baccio Bandinelli's Hercules and Cacus, Bartolomeo Ammannati’s Fontana del Nettuno and Benvenuto Cellini’s statue of Perseo holding Medusa's head.

The Cattedrale di Santa Maria del Fiore is the 
dominant feature of the Florence skyline

Travel tip:

The Florence duomo - the Cattedrale di Santa Maria del Fiore - with its enormous dome by Filippo Brunelleschi and campanile by Giotto, is one of Italy's most recognisable and most photographed sights, towering above the city and the dominant feature of almost every cityscape. From groundbreaking to consecration, the project took 140 years to complete and involved a series of architects. Arnolfo di Cambio, who also designed the church of Santa Croce and the Palazzo Vecchio, was the original architect.  When he died in 1410, 14 years after the first stone was laid, he was succeeded by Giotto, who himself died in 1337, after which his assistant Andrea Pisano took up the project.  Pisano died in 1348, as the Black Death swept Europe, and a succession of architects followed, culminating in Brunelleschi, who won a competition to build the dome, which remains the largest brick-built dome ever constructed.

Girolamo Riario - papal military leader

Assassinated after failed attempt to unseat Medici family

Girolamo Riario

Girolamo Riario, the 15th century governor of Imola and Forlì who was part of a major plot to displace the powerful Medici family as rulers of Florence, was assassinated on this day in 1488.

Riario, a nephew of Pope Sixtus IV who had appointed him Captain General of the Church, was unpopular with his subjects as a result of imposing high taxes, but his murder was thought to be an attempt by the noble Orsi family of Forlì to seize control of the city.

Two members of the family, Checco and Ludovico, led a group of assassins armed with swords into government palace, where Riario was set upon.  Despite the presence of guards, Riario was stabbed and slashed repeatedly.  Eventually, his dead body was left in a local piazza, surrounded by a crowd celebrating his demise, as the Orsi brothers and their gang looted the palace.

A decade earlier, Riario, who had been appointed Lord of Imola by Sixtus IV, joined with Francesco Salviati, whose family were the Papal bankers in Florence, and members of the Pazzi family in a plot to assassinate the ruler of Florence, Lorenzo de’ Medici, and his brother, Giuliano.

The Rocca di Ravaldino, a stronghold of Riario's power

The Pazzi were another important family in Florence and like many other families were resentful of Lorenzo’s despotic rule. Although Florence flourished, and his patronage of the arts was so important to the Renaissance, he maintained his power largely through bribery, threats and strategic marriages.

Riario’s involvement was essentially on behalf of his uncle, Sixtus IV, who saw Lorenzo – also known as Lorenzo the Magnificent – as a threat to the Papal States.

It was Lorenzo’s attempt to buy Imola – a small town but important as a stronghold on the border between the Tuscan empire and the Papal States – from its owners, the Sforza family of Milan, that led to Riario being installed as governer.  Lorenzo had offered the Duke of Milan, Galeazzo Maria Sforza, a sizeable sum for but Sixtus IV gazumped him, offering a deal by which Caterina Sforza, the Duke’s illegitimate daughter, would marry Riario, thus forming a strategic alliance.  The Pazzi family had financed the purchase.

The assignation attempt took place in Florence’s Duomo on April 26, 1478, during High Mass.  Giuliano was killed but Lorenzo escaped with only minor injuries. A simultaneous attempt to seize key government buildings in Florence was foiled and most of the key figures in the plot were captured and killed.  Riario, who would have been placed in charge of a new government in Florence had the plot succeeded, managed to get away. Salviati was not so lucky and was hung within an hour of his capture.

Pope Sixtus IV

Nonetheless, Riario continued to climb the ladders of power. In 1480, the pope made him Count of Forlì. He built the fortress of Rocca di Ravaldino, one of the strategically most important strongholds of the Romagna, and at the same time rebuilt much of Imola.

While his uncle remained pope, Riario and Caterina lived for the most part in Rome. As commander of the papal army, Riario wielded much power, although his wife had an increasingly strong influence over what he did. When Sixtus IV died, it was Caterina who ordered his troops to seize Castel Sant' Angelo to put pressure on the cardinals to elect a candidate who would work in accordance with the Riario interests. After 10 days of chaos in Rome, she had to be persuaded by Riario to withdraw in order for the conclave to begin.

However, the cardinals did not elect a new pope sympathetic to the Riarios, quite the contrary, going for Giovanni Battista Cybo, an old opponent, who became Pope Innocent VIII. He recognised Girolamo as Lord of Imola and Forlì and Captain-General of the papal forces but effectively allowed him no power.  It was his illegitimate son, Franceschetto, whom the Orsi family wanted to replace him.

After Girolamo’s death, Caterina was locked up, along with her children, but tricked her way out, promising to persuade the castellan, Tommaso Feo, to give up his defence of the Rocca di Ravaldino, which the Orsis had been unable to storm.

The Orsis had her children as hostages but Caterina reneged on their deal nonetheless.  From within the Rocca, she threatened dire consequences for the Orsi attackers if they dared touch the children and they fled, after which Girolamo’s son, Ottaviano, was made Lord of Forli with Caterina as his regent.

Imola's Rocca Sforzesca

Travel tip:

The city of Imola of today is part of the large metropolitan area of Bologna, in the Emilia-Romagna region. The castle, the Rocca Sforzesca, is well preserved, and is nowadays the home of an internationally respected piano academy and the Cinema d’Este, which shows films in July and August. The city is best known today for its motor racing circuit, which used to host the Grand Prix of San Marino on behalf of the nearby independent republic.

The Abbey of San Mercuriale in Forlì

Travel tip:

With a population of almost 120,000, Forlì is a prosperous agricultural and industrial city with a beautiful central square, Piazza Saffi, which is named after Aurelio Saffi, a radical republican who was a prominent figure in the Risorgimento. Its major attractions include the Abbey of San Mercuriale and the Rocca di Ravaldino, the strategic fortress built by Girolamo Riario and sometimes known as the Rocca di Caterina Sforza.
