Sith Empire

The Sith Empire, also known as the original Sith Empire, was an authoritarian empire that existed when the Sith first emerged as a threat to the peace and harmony on Remnant. Founded by the First Sith Salem, the Empire quickly conquered all of Anima, swiftly defeating all of the Jedi Order's forces on the continent.

However, Salem's apprentice betrayed her, which led to a series of infighting among the first wave of Sith, which would continue to be a trend in later generations and caused the Empire to fracture with several other self-proclaimed successors of Salem's original Sith Empire forming, leading to the Great Sith Wars. Salem eventually resurfaced with her Knights of Ren and took control of several of the so-called Sith Empire successors.

By the time of the Great War, Salem had fallen out of the public and elected to remain in the shadows to control her Sith and appointed a public leader. This leader was Darth Bane and his apprentice Darth Plagueis was unaware of Salem's affiliation up until Bane's death. The Imperial Kingdom was considered by Salem to be an incarnation of her original Sith Empire, incorporating many elements from it.
