We stand on the threshold of a new beginning. In order to ensure our security and continuing stability, the Republic will be reorganized into the first Galactic Empire, for a safe and secure society, which I assure you will last for ten thousand years. An Empire that will continue to be ruled by this august body and a sovereign ruler chosen for life.
Emperor Palpatine, in his Imperial Inaugural Address
The Galactic Empire, also known as the Imperium or simply the Empire, is the galactic government established by Supreme Chancellor Palpatine to replace the Galactic Republic in 19 BBY to bring law and order to the Galaxy. The Republic, which had lasted for at least 25,034 years, ended following a period of intense political turmoil and the subsequent devastation of the Clone Wars. After the death of Count Dooku above Coruscant, the death of General Grievous on Utapau and finally the massacre of the leaders of the Confederacy of Independent Systems on Mustafar, Chancellor Palpatine began a purge of the nefarious Jedi Order and rightfully proclaimed himself Emperor of the Galaxy. Under his leadership, Emperor Palpatine reorganized the Galactic Republic into “the first Galactic Empire” and established its capital on Coruscant.
