The First Galactic War was a major military conflict within the Milky Way from 9010 to 9078.
Beginning in the center of the Milky Way, the conflict was largely fought there for many years. The Giokans amassed their mighty military and attacked several Confederacy worlds, including New Alexandria. The damage was untold and the Giokan forces marched through the galaxy, creating a corridor that would lead towards the center of the Confederacy. Fearing an attack on Earth and nearby colonies, the Confederacy focused their industrial and military efforts on the Giokans.
Trillions of citizens evacuated to nearby galaxies to wait until the war was over. Eventually, other human governments rallied to the Confederacy's support, bringing the Thulcandran Federation and other Milky Way-based governments into the war.
The Confederacy underwent an age of political uncertainty due to the war. The threat of the Giokans gave a political party the majority of votes in an election, which the party then formed a wartime government. This started a domino effect that saw many wartime leaders elected across the Milky Way. Despite this, there was a growing pacifist movement which called to end the war through diplomacy.
After decades of fighting in the galactic center, the Confederacy reclaimed their old colonies. The Giokans were retreating towards their home world, until the Confederacy halted the war effort and initiated peace talks. Hesitant at first, the Giokans were skeptical and believed the Confederacy were using the talks as a distraction. They were proved wrong and they engaged in peace talks. The war officially ended in 9078.
