The Order of the Sith Lords, also known as Bane's Sith Order, Banite Sith, or simply Sith, is an ancient organization of Force practitioners skilled in the ways of the Sith and the power of the dark side. Approximately one thousand years before the Battle of Yavin, the Sith Lord Darth Bane engineered the destruction of the Brotherhood of Darkness in order to institute a rebirth of the Sith. Through the teachings of Darth Revan's Holocron, Bane developed the Rule of Two. Under this new tenet, only two Sith Lords were allowed to exist at any given time; a master and an apprentice; one embodied power while the other craved it. Hence, the Rule of Two was designed to cull the weak from the ranks of the Sith, thereby ensuring that only the strong remained. Bane's expectations of the new Order were met with his death at the hands of his own apprentice, Darth Zannah. The tradition was carried on over the next millennium, even though many Sith who followed in Bane's lineage were appalled at the thought of being slain by their own apprentices. After centuries of operating in secrecy, the Grand Plan for revenge was initiated by the Sith Lords Darth Plagueis and Darth Sidious. Sidious, who usurped his Master's position, ultimately fulfilled Darth Bane's dream: the return of Sith dominance throughout the galaxy. With the betrayal and near destruction of the Jedi Order, Sidious dissolved the Galactic Republic and replaced it with the Galactic Empire. Ruling as emperor in his public guise as "Palpatine", Sidious' reign was prophetically ended by his own apprentice the Chosen One, Anakin Skywalker. Though he returned in the form of several clones, each inhabited in turn by the Emperor's dark spirit, Sidious' final demise in 11 ABY ended the line of Bane and Zannah.
