Sith Empire

The Sith Empire, also known as the True Sith Empire, Reconstituted Sith Empire, or Resurgent Sith Empire was an empire created in the aftermath of the Great Hyperspace War of 5000 BBY. The remnants of the original Sith Empire established a reconstituted Sith Empire in the galaxy's Unknown Regions. This Empire, was created after Sith survivors of Dark Lord of the Sith Naga Sadow's disastrous campaign against the Galactic Republic fled known space to escape persecution by the Republic and its Jedi Order. Led by the Sith Lord Vitiate, the refugees wandered aimlessly through space in search of a new home. Twenty years after their departure from the original Empire's territory, the Sith discovered the forgotten world of Dromund Kaas and settled it to begin the process of rebuilding.

During the rebuilding process, Vitiate proclaimed himself to be the Dark Lord of his order and Emperor of his people. Under the care of the Emperor and his Dark Council of Sith Lords, the Empire established its capital of Kaas City and began building a mighty war machine, with the intent of eventually returning to combat with the Galactic Republic once more. The Empire worked towards that goal for over one thousand years, gradually expanding and gaining more power and influence. During that time, the Sith were discovered by Jedi Knights Revan and Malak, who were forcibly turned to the dark side of the Force by the Emperor and became Sith. Although they were sent back to serve as the vanguards of the Empire's eventual invasion, they broke free from his conditioning and formed concurrently their own Sith Empire, but the Republic defeated the two and their remnant, and knowledge of the Empire remained hidden.

With the war at an end and the Empire stronger than ever, the Emperor retreated from the public view and passed responsibilities of the day-to-day maintenance of the Empire to the Dark Council. As a result of the Empire's co-existence with the Republic, an interstellar Cold War emerged in the immediate aftermath of the Great War, during which time the Empire engaged in proxy battles and small conflicts with the Republic and its allies. When war did start up again, the Empire started to suffer catastrophic defeats that ranged from losing members of its leadership, including the Sith Emperor himself. Additionally, the Empire began to weaken even further due to infighting and internal struggles between power-crazed Sith Lords. It soon became just as vulnerable and desperate as the Republic it was fighting. The infighting was the turning point for the Empire when Darth Marr assumed leadership. With the help of the their most powerful allies, he was able to stabilize the Empire. Marr ensured a bright future and even organized an alliance with the Republic in dealing with threats such as Revan and Vitiate. The Emperor's Wrath was tasked with preserving the Empire and led the Empire's forces in the battle against Darth Malgus and the Dread Masters alongside Darth Marr.

In 147 ABY, after losing their capital, Dromund Kaas and the planet Byss, the Sith Empire collapsed.
