Coruscant

Coruscant (pronounced /'kɔɹəsɑnt/), also known as Imperial Center during the reign of the Galactic Empire, was arguably the most influential planet in the entire galaxy, located in the Inner Core. At various times in its history, it was the galactic capital and seat of government for the Old Republic, Galactic Republic and the Galactic Empire, and was the homeworld of the human species. After the signing of the Galactic Concordance on Coruscant, the New Republic opted to have both its capital and Senate rotate among member worlds rather than remain stationary to avoid repeating centuries of economic exploitation.
