Lucrezia Borgia was born on April 18, 1480, in Subiaco, then a town outside Rome and today a suburb of the Italian capital. She was a Spanish-Italian noblewoman who would marry several prominent Italian lords during the late 15th and early 16th centuries.
Her story unfolded during the Renaissance, an age of Michelangelo, da Vinci, and the Italian Wars. Yet her life was every bit as compelling, and it became surrounded by dark myths and legends.
Her father was Rodrigo Borgia, a Spaniard originally from near Valencia who had headed to Rome in the mid-15th century. Her mother was Vannozza dei Cattanei, Rodrigo's chief mistress in Rome.
Rodrigo rose quickly through the ranks of the Roman Catholic Church under the patronage of his uncle Alfonso, who was elected Pope Callixtus III in 1455. By the end of the 1450s, Rodrigo was a cardinal, a powerful office in the influential Papal State that controlled much of central Italy.
Rodrigo was not an average cardinal. He had many mistresses and fathered several children, though this was not uncommon for churchmen of the time. Great hypocrisy existed within the church: celibacy was preached, but prominent figures blatantly ignored it in their private lives, drawing criticism from church reformers.
With Vannozza, Rodrigo had four children. Lucrezia got along well with her siblings, especially her older brother Cesare. The two showed great affection toward each other, and Cesare would play a prominent role in his sister's later life, though their strong bond would later fuel dark rumors.
As the daughter of one of the most prominent religious figures of the day, Lucrezia received a significant education in the new humanist learning developed in Renaissance Italy, which focused on ancient Greek and Roman authors. She was tutored by Adriana Orsini of Milan, and through the Orsini she learned several languages, becoming fluent in later life in Spanish, Catalan, French, Italian, and Latin.
Her humanist education would have included a solid grounding in Greek and Roman literature, rhetoric, politics, logic, and philosophy, the core subjects of the humanist curriculum. She was growing up during a tumultuous period in Italian history.
Italy was then the center of European civilization, with cities like Rome, Florence, Venice, and Milan attracting the greatest artists of the day. Politically, however, the peninsula was chaotic and divided into more than two dozen large and small city-states.
The foremost included the maritime trading republics of Genoa and Venice, several city-states in the north such as the duchies of Milan, Ferrara, and Urbino, and Florence in Tuscany, which appeared to be a republic but was actually ruled by the famous Medici family. In central Italy lay the Papal State, ruled from Rome. In the south, the Kingdom of Naples and the island of Sicily were controlled by Spain.

From 1494, a series of wars broke out as Spain and France, rivals for dominion in the Italian peninsula, vied for influence after France began trying to acquire territory in the north. All of this mattered for Lucrezia because her father organized several marriages for her to strengthen the Borgias' position within this labyrinthine political landscape.
When she was just 10 years old, Lucrezia's father promised her hand in marriage to a Valencian lord. This and several other marital arrangements were called off in the years that followed as Rodrigo's political fortunes fluctuated.
His bargaining power changed dramatically in August 1492, when he won the contest to become the next pope. As Pope Alexander VI, he was able to negotiate a far more favorable marriage alliance through Lucrezia.
On June 12, 1493, she married Giovanni Sforza, a member of the powerful Sforza family, which ruled the Duchy of Milan and several other small states in northern Italy. This first marriage lasted only until 1497.
By then, the pope had decided that the alliance with the Sforzas was no longer the best option and that a better marriage alliance might be negotiated through Lucrezia if the union was annulled. Giovanni eventually agreed after pressure was applied, and he somewhat embarrassingly signed a document declaring that he could not consummate the marriage owing to impotence, sufficient grounds for annulment.
In response, it is believed that the humiliated Giovanni Sforza began to spread gossip claiming that Lucrezia engaged in sexual relations with her brothers and father. By now Lucrezia was nearing adulthood, and rumors abounded that she was pregnant at the time of the annulment owing to an illicit affair with a chamberlain who worked for her father, Pedro Calderon.
The events that followed are shadowy. Lucrezia disappeared from public for some time and may have given birth to her first child by Calderon in the weeks that followed. Calderon then became a victim of the Borgia family's ruthlessness in dispensing with embarrassing problems: he was found dead in the river Tiber in early 1498.
Her second husband, Alfonso of Aragon, met a similar bloody fate. Alfonso was a cousin of the Spanish royal family, having descended from the royal family of Aragon, whose king was Ferdinand of Aragon, one of the two monarchs of Spain in the late 15th century along with his wife Isabella.
Lucrezia's marriage to Alfonso in 1498 was part of her father's decision to temporarily back the Spanish in the Italian Wars. But the marriage would last only as long as Pope Alexander's diplomatic alignment, despite it being a good match: both were the same age and were even said to have fallen deeply in love.
In 1500, the Borgias decided to begin supporting France again. Thus the Borgias needed Alfonso gone, and he quickly showed up dead in Rome. Lucrezia may have been complicit in his murder, though the marriage had already produced a son named Rodrigo after his grandfather the pope.

Lucrezia's third and final marriage followed two years later. This was her most prominent marriage yet, and perhaps this is why it lasted. Her new husband was Alfonso d'Este, the son and heir of Ercole d'Este, duke of the significant city-state of Ferrara in northern Italy. He would soon succeed his father and become duke himself in 1505.
The marriage was celebrated in early 1502 and would last for the remainder of Lucrezia's life. It eventually resulted in several children, though the parentage of these may have been debatable, as Lucrezia, like her new husband, engaged in a string of affairs throughout the 1500s and 1510s.
These included a long-standing relationship between Lucrezia and the Marquis of Mantua, Francesco Gonzaga, and a separate affair with the Renaissance composer and literary theorist Pietro Bembo, who was widely regarded as having formalized the dialect of Tuscan Italian that subsequently became the standard version of the Italian language used throughout the peninsula.
Lucrezia's family relations, affairs, and marriages made her a focus of salacious gossip and many myths in late 15th and early 16th century Italy. For starters, there were many rumors about illegitimate children she had with her lovers, the first being Giovanni in early 1498, rumored to have been the product of her ill-fated affair with Calderon, though Giovanni's parentage is still disputed.
Additionally, accusations of an incestuous relationship with her brother Cesare abounded during her lifetime, particularly after her second husband was murdered in Rome in 1500, when Cesare was widely suspected of having ordered the murder. It is unlikely, however, that this had anything to do with bizarre lovers' jealousy; it was rather owing to Cesare's political activities at the time.
Lucrezia's brother had acted as their father the pope's general in extending the landed territory of the Papal State in central Italy during the late 1490s. His decision to kill Alfonso of Aragon in 1500 was a purely political decision tied to the papacy's diplomatic realignment and alliance with France at the time.
Lucrezia also developed a reputation as a femme fatale, one who seduced men at will and could poison them just as easily. She was rumored, for instance, to wear a hollow ring that opened to allow her to pour poison into her unsuspecting victims' drinks.
A notorious incident she was said to have been involved in was the Banquet of Chestnuts, a party thrown in Rome on October 30, 1501. Lucrezia, her brother Cesare, and their father Pope Alexander were said to have been involved in what was effectively a borderline orgy involving some of Rome's nobility and dozens of the city's courtesans.
There is only one account of the banquet, by the master of ceremonies at the papal court at the time, Johannes Burchard, and it is now assumed that the story was possibly entirely invented to smear the Borgia family name. It is possible that Lucrezia was neither a femme fatale nor even particularly scandalous in her love life compared with any other aristocratic lady in late Renaissance Italy.
There is no doubting that she was considered especially attractive by contemporaries, but her good looks need not necessarily have resulted in any particularly sordid behavior. Rather, she seems to have been stigmatized owing to her family's dubious actions in the 1490s and 1500s.

Her father the pope had several mistresses and encouraged his son to carve out his own kingdom in central Italy using the resources of the Holy See of Rome. Cesare was the most notorious of Renaissance lords, casting central Italy into chaos in the 1490s and reputedly influencing Niccolo Machiavelli when he later wrote his notorious political treatise, The Prince.
Lucrezia's adult life was spent at the Este court in Ferrara, where her third husband became duke in 1505. As noted, she engaged in a string of affairs, though this was hardly unusual by the standards of late Renaissance Italy.
This was complicated by one of her lovers, Francesco Gonzaga, having contracted syphilis around the time of, or shortly before, their affair. The disease had arrived in Europe with devastating consequences in the late 15th century following European contact with the Americas.
Though easily treated today with antibiotics, in the early modern period syphilis slowly devastated the body, beginning with a rash around the genital region, then spreading further, and finally leading to deformities and often the collapse of parts of the body such as the nose if the disease lingered for months or years. Yet Lucrezia apparently did not contract the disease from Francesco, which women are less prone to.
Her father, Pope Alexander, died in August 1503. He was a curious man, a ruthless Renaissance prince who broke all the rules associated with his office, but he was remembered fondly by some of the other popes of the time.
With his position weakened following their father's death, Cesare began to lose control over some of the territories in central Italy he had conquered in the 1490s. He was eventually arrested by King Ferdinand of Aragon and transferred to Spain in 1504. He spent over 18 months in prison there before escaping and launching a revolt in the north of the country, which ended in his death in March 1507.
Thus, within a few years in the 1500s, Lucrezia went from being the daughter of one of the most powerful families in Italy to being an isolated figure descended from the fallen House of Borgia. She had at least eight children, the legitimacy of which was questionable, and perhaps as many as ten depending on the parentage of two others.
However, she also had several difficult conceptions and miscarriages during the 1500s and 1510s. In the end, it was this turbulent natal history that led to her death on June 14, 1519.
She gave birth to a baby girl who was christened Isabella. It had been another complicated pregnancy for Lucrezia, and this time she never fully recovered. She fell ill after the birth and, despite improving for a few days in the week that followed, she worsened and died on June 24 at the age of 39.
She was buried in the church of Corpus Domini in Ferrara, the last major figure in the turbulent Borgia dynasty that had been so prominent in Italy since the mid-15th century. Lucrezia has been one of the most widely studied women of early modern Italy ever since her death.
In 1833, the great French writer Victor Hugo scripted a stage play named after her, retelling a version of her life. In the 20th and early 21st centuries, she has been featured in numerous books, films, television series, and even a video game, in which many of the rumors that surrounded her during her lifetime have featured prominently.
