The Galactic Center of Coruscant (pronounced /'kʊɹəsɑnt/), also known as Imperial Center or the Queen of the Core, was the political hub of the galaxy for millennia. It was generally agreed that Coruscant was, during most of Galactic history, the most politically important world in the galaxy. At various times, it was the capital of the Galactic Republic, the Galactic Empire, the New Republic, briefly the Empire Reborn, the New Republic, the Yuuzhan Vong Empire occupation, the Galactic Alliance, the Fel Empire and Darth Krayt's Sith Empire. These governments, that all controlled Coruscant, controlled the galaxy in the process.
A large number of the galaxy's trade routes—including the Perlemian Trade Route, the Corellian Run, the Metellos Trade Route, the Koros Trunk Line, and the Leisure Corridor—went through Coruscant, making it one of the richest worlds in the galaxy. Tellingly, the planet's hyperspace coordinates were (0,0,0), and the military designation was Triple Zero. Accordingly, it was the main planet of the all-important 'Sector Zero', a military designation for the Coruscant and surrounding systems.
The actual planet-wide metropolis of Coruscant was divided into smaller 'cities', (though each was the size of the average country by most standards). Among these was the administrative center, known as Galactic City, Republic City, Coruscant City or the City of Spires under the Galactic Republic, Imperial City during the rule of the Galactic Empire, and New Republic City under the New Republic, and later Yuuzhan'tar when the planet was under Yuuzhan Vong control
