The Dominion was reformed under Emperor Valerian Mengsk under a new and fairer rule, but this rule was tested with the advent of the End War and the return of Amon, which ended in terrans pushing back Amon's forces and defeating him in the Void. Ultimately, the terrans survived the conflict, but at great damage to the Dominion, and the loss of Emperor Mengsk. Sarah Kerrigan's objective was the recovery of the Keystone, and the invasion was a way of searching for it. The terran polities were engulfed at the start of the Second Great War by a massive zerg invasion.

On the eve of war, Raynor's Raiders resumed its anti-Dominion campaign after a period of relative inactivity.

īy the Second Great War, the Dominion was the strongest terran force in the Koprulu Sector, vying with the Kel-Morian Combine and the Umojan Protectorate for influence. Ultimately the sector escaped UED control, but it left the Dominion weak and with the zerg as the sector's dominant power. After approximately six months of stability, the Dominion came under attack by the UED. The new Earth government, the United Earth Directorate, dispatched an Expeditionary Fleet to take control of the sector and defeat the aliens. However, no interference came from Earth until the discovery of the alien invaders, sparking panic. Unknown to the terrans of the Koprulu sector, the humans of Earth were aware of their existence. The Sons of Korhal eventually destroyed the Confederacy by using stolen psi emitters to lure the zerg to Tarsonis the rebels created the Terran Dominion, based on Korhal, to replace the Confederacy. ĭuring the Great War, the Terran Confederacy, experimenting with psi emitter technology, bore the brunt of attacks by the zerg (infested planets were frequently purified by the protoss) while facing the Sons of Korhal. The Confederacy was the strongest faction. Prior to the Great War, the terrans were primarily divided into three factions in the Koprulu sector, each based on one of the original settled planets – the Terran Confederacy, Kel-Morian Combine and Umojan Protectorate. Eventually the supercarrier technology broke down. The terran population expanded rapidly for at least three generations, and for the first five or six generations there was pressure to have many children. The terran colonists had access to stores of fertilized eggs and frozen embryos, and even extensive cloning, using technologies found on the supercarriers. The terrans arrived in the Koprulu sector via supercarriers in 2259, landing on three separate planets – Tarsonis, Moria and Umoja.
