Realizing that the Sith's greed led to their destruction, Bane created the Rule of Two. The Sith thenceforth consisted of only two Sith Lords at any given time; the master who embodied the power of the dark side, and the apprentice who craved that power.
Darth Bane created the rule of two because he saw that having more than two Sith leads to weakness. You see, before the time of two a powerful Sith lord would be taken down by a group of weaker ones, they would then share their power.
After a couple hundred years of failed wars and galactic invasions the Sith realiced that there were two many sith. By nature most Sith will betray eachother and that is their downfall so to make the risk of betrayal significantly lower they made it so that there were only two Sith running around.
The Inquisitors weren't Sith. Palatine very much respected the Rule of Two so even after his victory he had only one Sith apprentice; Vader. The Inquisitors were force sensitive being trained by Darth Vader in basic combat and the ways of the Dark Side.
Opposing them stand the canonical servants of the Dark Side of the Force: The Sith. While many Sith Lords are mentioned, only six are detailed in canon: Bane, Plagueis, Sidious, Maul, Tyranus, and Vader.
As the first Dark Lord of the Sith, Ajunta Pall founded the first Sith Empire and expanded it onto other worlds. The Sith took over the planet Ziost and created it as their capital and as Pall's new home.
George Lucas himself has stated that Anakin is the Chosen One and that the prophecy is true, although it had been misinterpreted by the entire Jedi Order.
Sidious broke the Rule of Two at least twice: once by training Darth Maul while still under the tutelage of Darth Plagueis; and secondly, by taking on two apprentices at once, and in the form of two Jedi: Count Dooku, the former Padawan of the legendary Jedi Master Yoda, dubbed Darth Tyranus, and the Fosh Jedi Vergere.
History. A dark side warrior with a mysterious past, Kylo Ren was neither Jedi nor Sith, but a product of both sides' teachings. Once an apprentice of Luke Skywalker's, he killed his fellow students and drove Skywalker into exile, becoming a First Order warlord and servant of Supreme Leader Snoke.
Description and relationship to the Sith
Despite the fact that both groups called upon the dark side of the Force, Dark Jedi were not the same as the Sith, though the first group of Dark Jedi were the predecessors of the Dark Lords in the ancient Sith Empire.
Successor of the Doctrine of the Dyad, the law decreed that only two Sith Lords must exist at any given time: a master to represent the power of the dark side of the Force, and an apprentice to crave it and train under the master and to one day fulfill their role.
Undermined by constant infighting and ruined by the last war against the Jedi, the Sith were rendered all but extinct with the exception of one; Darth Bane survived the ancient order's destruction and passed his knowledge to a single apprentice, Darth Zannah, before being entombed on Korriban, which became known as ...
In the Sith Empire, as time progressed pure-blooded Sith were steadily bred out, resulting in only a few pure-blooded Sith left in the Sith Empire by the time of the Great Hyperspace War (5000 BBY). By 44 ABY, the true Sith species in the Empire were believed to have gone extinct due to the interbreeding process.
Darth Jar Jar, known to most as Jar Jar Binks, was a Gungan Sith Lord. He survived the Battle of Naboo and became a Representative of Naboo, when he helped to give Darth Sidious emergency powers.
After the Sith were decimated by the Jedi Knights of a thousand years ago, Bane enacted the Sith rule of two: there would be only two active Sith at one time -- a Dark Lord to embody the power, and an apprentice to crave it.
A deadly, agile Sith Lord trained by the evil Darth Sidious, Darth Maul was a formidable warrior and scheming mastermind. He wielded an intimidating double-bladed lightsaber and fought with a menacing ferocity.
The Last Jedi took the stance that Rey's parents were nobody, and while this may have been true from a certain point of view, The Rise of Skywalker gave us the true answer to Rey's parentage. In the film, we learned that Rey was a Palpatine, and her father was a clone of the infamous Sith Lord.
Disturbed by her Sith lineage, Rey exiles herself on Ahch-To. Luke's Force spirit encourages her to face Palpatine and gives her Leia's lightsaber and his old T-65B X-wing Red Five.
This use of a Force power generally reserved for the Sith is foreshadowing for the movies biggest twist: Rey herself is a Palpatine, born of Sith blood and heir to the throne of her grandfather's Final Order.
In non-canon material it is said that Palpatine had a number of concubines and never took a wife in fear that he would produce a legitimate heir. One of these non-canon concubines was Roganda Ismaren, a former Jedi who survived Order 66, and lived for a time at Palpatine's side.
In The Rise of Skywalker's novelization, written by Rae Carson, it's revealed that Rey's father is a failed Palpatine clone. He was initially created as a vessel to house the Sith Lord but proved incapable of doing so.
Snoke Is Not a Sith Lord
But the fact that he's a bio-engineered being created by Palpatine explains why his training of Kylo Ren followed the Sith mold so closely, since all along Palpatine was trying to manipulate Ren.
According to Darth Sidious, Darth Plagueis was a powerful Sith Lord who was able to use the Force to influence the midi-chlorians to create life, a power that was reportedly to be extremely rare for one sensitive to the Force to possess, and could even be used by certain Sith Lords to prolong or even cheat death.
A Sith Lord with the ability to prevent death and create life, Plagueis is the mentor of Sheev Palpatine/Darth Sidious, who, in accordance to the Sith's Rule of Two, eventually betrays Plagueis by murdering him in his sleep, taking his place as Sith Master.
