Etymology

From dark + side. Sense 2.1 (“side that is evil”) was popularized by the film Star Wars (1977; later retitled Star Wars: Episode IV – A New Hope) where the term was used to describe the aspect of a metaphysical power called the Force which could be used to act aggressively and perpetrate evil.
