The Galactic Empire, also known as the New Order, the First Galactic Empire, the Order or simply the Empire, was the government that rose to power in the aftermath of the Clone Wars, replacing the Galactic Republic. Central authority was given to Darth Sidious (The Emperor), publicly known as Emperor Palpatine, who is also the Dark Lord of the Sith. For nearly two decades, the legislative body was the Imperial Senate, but it was dissolved by the Emperor shortly before the Battle of Yavin. During the reign of the Empire, countless star systems are being conquered and dissident actions ruthlessly stamped out by the rapidly expanding Imperial Army and Navy. The Empire also oversaw the near extermination of the Jedi, with the destruction of the Jedi Temple on Coruscant and its renovation into the newly named Imperial Palace.
