Republic

The Republic is a moniker applied to several interstellar states throughout history. These include:
 * The Shantarak Republic (no longer extant)
 * The Gorf People's Republic (more often "Gorf Republic")
 * The K'Taknor Republic
 * The Grikoliok Republic
 * The Renjath Grand Republic (more often "Grand Republic")
 * The Mekh'LeSth United Planetary Republic (more often "Planetary Republic")

These states may all be colloquially referred to as the Republic, though distinctions are made when they need to be distinguished from each other.

Each of these states maintains (or maintained) a democratic system of government, which can accurately be called a republic.
