The New Republic was the formalized title of the government established by the Rebel Alliance in the aftermath of the Battle of Endor. At the time of signing, only around 40 planets openly declared their support of the reformed Republic. Despite initial claims, it would take them three years to take Coruscant and establish themselves as the leading galactic power. Even then the Republic had only 600,000 member worlds by it's height, small compared to the 12 million member worlds currently held by the Empire. It would take them less than 25 years after that to re-establish the Old Republic's ineffectual power structure, just in time for war with the Yuuzhan Vong. This demonstrated just how pathetic the New Republic had become and would result in the formation of a more federal system of government, which eventually became a new Galactic Empire.
