The Third Sith Empire was a Sith faction during the Great Territorial War and the Great Sovereign Crusades, two conflicts in which the Sith fought against the Galactic Republic and the monastic Jedi Order. Having risen after the collapse of the Second Sith Empire, a collapse brought about due to internal struggles in the faction, the Third Sith Empire was the main driving force behind the beginning of the Great Territorial War.
A few years after the faction’s creation, the Sith orchestrated the Uvena Conflict, a war in the Uvena system between the planets Uvena Prime and Uvena III, in order to secure a weapons flow from the Uvena system to use in a war effort against the Republic. Jedi Knights Ussej Padric Bac and Damien Nightblade discovered the Sith plot and reported it back to the Republic’s Supreme Chancellor Stavan Jetzt, who subsequently declared war on the Third Sith Empire. This declaration of war officially started the Great Territorial War, where the Sith fought for a few years against the Republic and the Jedi.
Sometime after the end of the Great Territorial War, the Third Sith Empire became involved in the Great Sovereign Crusades, another conflict where it fought against the Republic and the Jedi. The Mandalorian Clans were also involved in the war, where they carried out the Battle of Utapau.
