The Code of the Sith, also known as Qotsisajak, was a mantra that expressed the core beliefs of the Sith. It was an inversion of the Jedi Code, a set of rules for members of the Jedi Order. It notably taught its followers that it is for the strong to destroy the weak.
In some versions of the Code, the initial line "Peace is a lie" was repeated after "The Force shall free me."
The Code of the Sith first appeared in Star Wars canon in the Star Wars: The Clone Wars episode "Altar of Mortis." The Code of the Sith was originally created by David Gaider, who wrote the Korriban segment of the Star Wars Legends 2003 video game Star Wars: Knights of the Old Republic. Initially, Gaider had asked Lucasfilm Ltd. whether the Sith had a written creed like the Jedi did. When he was told to write one specifically for the game, Gaider reversed the existing Jedi Code and complemented it with a Sith philosophy partly inspired by Mein Kampf, the 1925 infamous autobiographical manifesto written by the Nazi leader Adolf Hitler.
