The Galactic Republic is the name of the interplanetary State used in the fictional Star Wars universe prior to the establishment of the Galactic Empire. The form of this government, created by the Senate, was introduced in the Prequel Trilogy. By the time of the original Star Wars trilogy, it is referred to as the Old Republic. It was a democratic, though eventually ineffectual, constitution republic tied up in layers of bureaucracy.
The Republic, as it was commonly known, was a republic government that was able to sustain itself for over twenty-five thousand years.
The Republic itself was formed in 25,053 BBY when the first "Galactic Constitution" was signed on Coruscant, after the Corellian Hyperdrive connected many worlds in the Galactic Core. Whether this means that Coruscant was the original homeworld of humans or simply the most powerful world at the time is still up for debate, and there has been little said about the event other than that it occurred. The Republic was made up of several hundred thousand worlds.
The Republic began as a mutual protection and economic alliance among a number of planets in the Galactic Core. Each member world chose a Senator to represent them in the Republic Senate, a central Legislative body. Senators were ambassadors of their homeworld, and member worlds were able to maintain their government and society in accordance with local beliefs, customs, and traditions. There were a wide variety of different local governments along the political spectrum: from Monarchies to Republics to Hive-like communes. In some systems, the senator was elected to that post; in others the world government appointed the senator. Naboo's monarch appointed their senator, while the Alderaan Council of Elders elected their senator out of their own ranks, usually the heir to the Royal House of Organa and their bloodline, as the heir was also the leader of the council.
