Great Hyperspace War

The Great Hyperspace War represents a significant and consequential conflict in the Star Wars universe, occurring around five thousand years before the rise of the Galactic Empire. The war is chronicled in the Tales of the Jedi comic series, released in the 1990s. The conflict started when two explorers, Gav and Jori Daragon, discovered the Sith Empire by chance after activating a hyperspace route called Koros Major. Against their will, the pair got entangled in the power struggle amongst the Sith, led by Naga Sadow, who sought to use their arrival as a catalyst to instigate war against the Republic.

The primary cause of The Great Hyperspace War was the Sith's ambition to expand their empire. Naga Sadow, the Sith Lord, saw the arrival of the Daragons as an opportunity to rally the Sith for war. Using illusions, Sadow deceived the Sith into believing that they were under attack by Republic forces, thereby thrusting all of Sith into a war with the beleaguered Republic.

Capitalizing on the Sith's fear and unpreparedness, Naga Sadow manipulated events in his favor and orchestrated a massive pre-emptive assault on the Republic. The Daragons helped the Republic resist Sith invasions by revealing key strategic information about the Sith Empire, throwing the Sith forces into disarray. The war reached its zenith in a massive battle at the star of Primus Goluud, where Sadow's flagship was destroyed.

The Great Hyperspace War had a severe impact on both the Sith and the Republic. The war led to the near-extinction of the Sith, with the few survivors forced into hiding for centuries. This would eventually lead to the rise of the Rule of Two and Darth Bane's reformed Sith Order. The Republic, meanwhile, withstood the onslaught despite heavy losses and enacted strict policies regarding unsanctioned hyperspace exploration to prevent additional surprises. These events highlighted the expanding tensions between the Republic, Jedi, and Sith, setting the stage for many future conflicts.

the Great Hyperspace War transformed the landscape of the Star Wars universe. The war decimated the Sith, causing them to go underground and adopt new survival tactics. It also led to the strengthening of the Republic's defense infrastructure and set a precedent for future engagements with the Sith. The effects of this colossal conflict resonated throughout the Star Wars timeline, shaping the universe in significant and lasting ways.
