Niccolò Machiavelli (1469–1527) is a classic author whose works are in the public domain.

Before power became a dirty word, Machiavelli stripped away moral pretense to show exactly how rulers actually acquire and maintain power, creating a manual so controversial it's been banned, burned, and secretly studied for 500 years.

Machiavelli strips away the myth of noble leadership to reveal power as a ruthless game of psychology and pragmatism—a handbook that explains not how rulers should act, but how they actually do.
