Word Origin and History for Machiavellian
adj.

"cunning, deceitful, unscrupulous," 1570s, from Niccolo Machiavelli (1469-1527), Florentine statesman and author of "Del Principe," a work advising rulers to place advantage above morality. A word of abuse in English well before his works were translated ("The Discourses" 1636, "The Prince" 1640), in part because his books were Indexed by the Church, in part because of French attacks on him (e.g. Gentillet's, translated into English 1602).
