On the method of dealing with the Rebellious Peoples of Valdichiana (Italian: Del modo di trattare i popoli della Valdichiana ribellati) is a 1503 work by Niccolò Machiavelli. A short excerpt in English may be found in Allan Gilbert's Machiavelli Volume One. Machiavelli also witnessed the bloody vengeance taken by Borgia on his mutinous captains at the town of Sinigaglia (December 31, 1502), later writing a famous account. In much of his early writings, Machiavelli argues that “one should not offend a prince and later put faith in him.”
