He accused Lucrezia of
INCEST with her father and her brothers, Cesare and Giovanni, the Second Duke of Gandia.
The Pope used the only valid argument for annulment, the non-consummation of the marriage, and he offered his son-in-law all of his daughter's dowry. The head of the Sforza family threatened to withdraw his protection if his nephew refused the Pope's offer. Giovanni Sforza had no choice, and signed a confession of impotence and the documents of annulment before witnesses.
So much for husband number one. He was actually quite fortunate to escape with his life.
During the bargaining over the divorce, Lucrezia retired to a nearby convent, her only communication with her father during her enforced stay being messages brought by a young chamberlain, Perotto. Six months later, pregnant from a liaison with Perotto, Lucrezia participated in a ceremony in which Vatican judges attested that she was intacta, that is, a virgin. Giovanni Sforza gave sworn testimony to this fact, and the divorce was pronounced "final."
Cesare, discovering his
sister's pregnancy, was furious. He made a run at the young Perotto with drawn sword, stabbing him as he knelt before the papal throne, splashing Perotto's blood on his father. Perotto survived the attack, but was thrown into prison. A few days later, Burchard reported that Perotto "had fallen into the Tiber against his will." Six days later, Perotto's body was fished out of the river, along with that of Lucrezia's chambermaid, who, it was believed, had facilitated the affair.
The child from this liaison was born in secret, and, when he was finally recognized, was called the infans Romanus. He was named Giovanni, and is a somewhat mysterious figure in the Borgia history. This child did not surface until three years after his birth, when Alexander declared that he was indeed the infans Romanus, the child of Rome, and was the offspring of Cesare and an unknown woman. This first papal bull was followed by a second, which acknowledged that the child was the
son of the pope himself, even though the pope would have been sixty-seven at the time of the child's conception. The purpose of the papal bulls was to give Alexander the excuse to name the young Giovanni the heir to the duchy of Nepi, a property important to the Borgia family. This subterfuge to legitimize the infans Romanus simply led people to assume that the boy was the child of Lucrezia and Alexander, or of Lucrezia and Cesare. The historian Potigliotti suggests that Lucrezia insisted on the two papal bulls because she didn't know which of her two lovers, her father or her brother, had actually fathered the child. Giovanni was passed from guardian to guardian, eventually ending up with Lucrezia in Ferrara as "her half brother." The unfortunate Giovanni never inherited his titles, and, after a lifetime of serving as a minor functionary in the courts of the Vatican and France, died relatively unknown in 1548. The rumor of incest as his origin was begun with Lucrezia's first husband's attack on his former in-laws, and has persisted to this day. It may be true, or it may be that he was the offspring of Lucrezia's indiscretion with Perotto.
I have put in BOLD to emphasize incest. The above text is from the link below.
BORGIA
There was a Schism in the Roman Catholic Church in 1378. The King of France being the most powerful King in Europe didn't like the Italian Pope so he elected one o fhis own. The Popes called each other the anti-Christ.
