The term "Purge" commonly refers to the fictional annual event depicted in "The Purge" film series, where, for one night each year, all crime, including murder, is legal. However, there is no real-life equivalent of this event.
The concept is a piece of dystopian fiction that serves to explore themes like social inequality, violence, and government control. The films, starting from "The Purge" (2013) and followed by several sequels and a television series, have speculative elements intended to provoke thought about morality and society rather than reflect actual events.
