Great Galactic War

The Great Galactic War otherwise known as the Great Galactic Conflict, was a full-scale, Galaxy-spanning conflict between the Galactic Republic, and Jedi Order against the Sith and their followers. The war can be traced back to the Coo-Neo Crisis and the death of a Sith minion. The conflict started with the invasion of Republic space by the Sith in 22 BBY, not long after the Coo-Neo Crisis and the departure of Scott Borek, Phyllius Marks and Alec Prime from the known Galaxy. Many of the main skirmishes took place away from the, (mostly in the and ) but a few like the Battle of Corellia and the Battle of Coruscant reached the heart of the Republic.

Origins
Many historian believe the start of the Great Galactic War began during the Coo-Neo Crisis when Jedi Knight Scott Borek engaged and (mistakenly) was thought to have killed the Dark Jedi Zell Coo-Neo, a Sith minion. Many thought this led the Sith to re-enter the spotlight, and consequently into the knowledge of all, to punish the Republic in an act of retribution for the death of one of their members. The Sith fought on many  worlds in the beginning of the War, though no one saw any of the Sith on the actual battle-field. Several Senators against the war and conspiracy theorists in the Republic thought this might be an attempt by the Supreme Chancellor to remain in office or attempt to stimulate the economy or even to prune the unwanted from the galaxy (a sort of population control). This veiled and guerilla warfare tactic the Sith implemented in their campaign's lasted two years until the re-emergeance of Scott Borek, and Alec Prime. Darth Nemis was the first Sith to reveal himself, during the Battle of Endor. The veiled tactic resulted in victories on, , and , two of those worlds housed droid and weapons manufacturing companies, that would supplement the Sith military later in the war.
