||Coruscant, also known as Imperial Center or the Queen of the Core, was a planet located in the Galactic Core. 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, the Yuuzhan Vong empire, the Galactic Alliance, very briefly the Fel Empire, Darth Krayt's Galactic Empire, and the Galactic Federation Triumvirate. In controlling Coruscant, these governments controlled most of the galaxy in the process. Over the centuries, Coruscant had developed into an ecumenopolis, with a total of 5,127 levels of city built up from the crust by the time of the Clone Wars. The actual planet-wide metropolis of Coruscant was called Galactic City. Under the Galactic Republic, the names Republic City or the City of Spires were also used to reference the city. It was also called Imperial City under the Galactic Empire, and New Republic City under the New Republic. However, in practice, Galactic City and its other names were sometimes applied to the Senate District, the central government center and de facto capital of Coruscant. Under the Yuuzhan Vong, the city and planet were both referred to as Yuuzhan'tar.
