The Galactic Republic was the ruling government of the Universe for nearly a thousand years, until the establishment of the Galactic Empire in 19 BBY. It was also known as the Universal Republic, the First Republic, or simply as the Republic during its existence. Following the establishment of the Empire, it would be referred to as the Old Republic or the Old Order. The Republic, led by a Supreme Chancellor, had a supposedly democratic government that was able to sustain itself for nearly a millennia. For most of its duration as the dominant Universal power, the Republic did not style itself as a strong, centralized, and highly organized government, but rather as a union, alliance, or federation of dimensions and worlds for the purposes of promoting commerce, mediating disputes, and providing mutual protection. It is said that its complete history would have filled a "thousand libraries". In its latest years, it was a benevolent-though ineffectual-government tied up in layers of bureaucracy.
This page lists a variety of dimensions and dimensional worlds in the Universe, and notes their membership status under the Republic. The Republic never held authority over the entire extent of known space; there were dimensions or worlds which remained undiscovered, or never joined the Universal Government. Nevertheless, more than eighty percent of the Universe's dimensions and worlds were "members" or "protectorates" of the Republic. Each world and dimension sent a Senator to the Galactic Senate, the Universe's legislative body. A common currency, the universal credit, was accepted throughout Republic space; the Republic Military provided an overall defense for the Universal Government; and laws passed by the Senate were binding upon all dimensions. The Supreme Court of the Republic served as the highest court of law, and the Supreme Chancellor was recognized as the head of state, head of government, leader of the Senate, and "first among equals" of all universal leaders, monarchs, and personages. Each dimension and world, however, retained its own leaders and government; maintained its own military and law enforcement forces; and adhered its own local laws, customs, and regulations. They each had an extensive amount of internal autonomy.
All territories belonging to the Republic and the Confederacy of Independent Dimensions at the end of the war became part of the Galactic Empire upon its foundation. The Empire subjugated many of the Republic's former member worlds and dimensions, enslaving, deporting, or quarantining their native inhabitants, and assuming direct control over their governments. Worlds and dimensions subjected to such treatment are noted below.
