From which period does the modern term 'Machiavellian' originate, describing someone willing to commit bad acts in exchange for personal gain?

The term 'Realist' refers to a later philosophical and artistic movement that emerged in the 19th century, focusing on depicting everyday life and society without idealization. While realism in politics shares some philosophical ground with Machiavellian ideas, it is not the origin of the term itself, which is firmly rooted in Renaissance thought.

The Classical period refers to the ancient civilizations of Greece and Rome, which significantly influenced later thought, including Renaissance ideas. However, Machiavelli's theories and the term 'Machiavellian' specifically emerged much later, during the Renaissance, making this choice inaccurate.

The Enlightenment was a philosophical movement in the 17th and 18th centuries that emphasized reason, individualism, and skepticism of traditional authority. Although Machiavelli's ideas influenced Enlightenment thinkers, the term 'Machiavellian' specifically links back to the Renaissance period, not the Enlightenment.
