Sith Empire

The Sith, collectively known as the Sith Order, were an order of Force userswho utilized the dark side of the Force in an effort to gain power over the galaxy. The Sith were the ancient enemies of the Jedi Order and fought numerous wars with them across the millennia.

History
The Sith were the ancient enemy of the Jedi Order. They were formed during the Hundred-Year Darkness, thousands of years prior to the Clone Wars. The first Sith was a rogue Jedi who believed in learning the ways of the dark side. The Sith built empires on the backs of their slaves[20] and fought wars against the Jedi for control of the galaxy, during which time they built massive superweaponspowered by giant kyber crystals. At one point, nearly six thousand years before the rise of the Galactic Empire, the Sith built a shrine on Coruscant, which became a place of immense dark side power. Later in history, the Jedi raised their own temple over that shrine in hopes of stomping out its power. The Sith Order's traditional homeworld was Moraband, a planet of red sands that the group was forced to abandon after it was scarred by many wars.[19]

Their quest to gain power was ultimately the undoing of the Sith, as the dark side made them turn against one another. With their numbers reduced, the Sith were all but defeated by the Jedi. Darth Bane survived, however, and created the Rule of Two, mandating that only two Sith—a master and an apprentice—could exist at any given time, lest they fall prey to in-fighting.[3]
