The Order of the Sith Lords (also referred as Bane's Sith Order, the Banite Sith Order, or simply Sith) is a fictional ancient kratocraticorganization, created by Darth Bane after the destruction of the Sith Brotherhood of Darkness-dynasty that lasted 1000 years, and promptly ended with the death of Palpatine.
The Sith are the primary recurring antagonists in the Star Wars universe. Its members were dedicated to Sith philosophy and to mastering the dark side of the Force.[1] The Sith members, known as Sith Lords or Dark Lords of the Sith, traditionally use the title Darth before their Sith name. The Sith are the archenemies of the quasi-religious Jedi and, like them, their main weapon is the lightsaber. By the events of both trilogies, there exist only two at a time: a master and an apprentice.
The first use of the word "Sith" was in the novelization of Star Wars: Episode IV - A New Hope, as a title for Darth Vader, the "Dark Lord of the Sith". The Sith were not formally introduced or mentioned on-screen until the release of Star Wars: Episode I - The Phantom Menace, in 1999, though they had been named in some Expanded Universe works before that time.
