Coruscant, originally called Notron, also known as Imperial Center or the Queen of the Core, is a planet located in the Galactic Core. It is generally agreed that Coruscant is, 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, and now currently, the New Republic. In controlling Coruscant, these governments controlled most of the galaxy in the process.
Over the centuries, Coruscant has 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 is 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.
