The Fourth Republic was, within weeks of its founding, the target of a string of terrorist attacks. The majority of them were in fact plotted by the Sith Lord Darth Wirlokk in an attempt to destabilize the fledgling government. However, most of the attacks were thwarted, and the Republic only emerged stronger from these early trials. Throughout 4130, the Republic's territory grew as systems left the CIUS and joined the more reputable Republic. By the end of the year the Republic was the undisputed superpower, controlling fully 3/5 of the galaxy.
