Initially members of the Galactic Republic, the Svivreni forbade weapons on their planet and exacted strict punishment for outlaws, including execution, which reduced crime and was one of the factors that turned Svivren into an important trade world. The species avoided involvement in the Clone Wars and tried to remain neutral during the Galactic Civil War. In the days of the New Republic, the Galactic Empire attempted to conquer Svivren, but the Svivreni resisted Grand Admiral Thrawn's attacks through sheer obstinacy. The species later associated with the Galactic Federation of Free Alliances and the Galactic Alliance Remnant.
