How did Pier Paolo Boscoli give Machiavelli a bad reputation?

Answer 1

In 1494, he helped a French king Charles VIII to invade Florence to drive out the Medici, who were the leaders of this city for many years.

Machiavelli has gained an important result of this event

So, in 1512, when Lorenzo II de Medici returns to Florence: he tortures the Florentines to revenge their previous defeat. He accuses Machiavelli of involvement in this conspiracy with Paolo to have an important position.

Machiavelli lost its political place, he was tortured... and so on

Answer 2

Pier Paolo Boscoli contributed to tarnishing Machiavelli's reputation by portraying him as an advocate for tyranny and cruelty in his biography of Machiavelli published in 1520, just a few years after Machiavelli's death. Boscoli's depiction of Machiavelli as a teacher of evil and immorality greatly influenced how people viewed Machiavelli's political writings, such as "The Prince."
