The Treaty of Coruscant marked the end of the Great Galactic War between the Galactic Republic and the Sith Empire. The two factions met on Alderaan to discuss the terms of peace, while the treacherous Sith launched a simultaneous attack against the Republic on their home world of Coruscant. The sacking and occupation of Coruscant allowed the Empire to force the Republic into a completely helpless position, leaving them no choice but to surrender to the Empire's terms. The Republic gave up control of multiple star systems and trade routes to the Sith Empire and gained little to nothing in return. This treaty marked the beginning of a Cold War.
