Government long established should not be changed for light and transient causes, but when a Government displays a history of usurpation, abuse and moral atrocity, displaying a clear design to subjugate totally and absolutely beings born free under the auspices of nature, it is our right - our duty - to depose that Government. We believe that the Galactic Empire has willfully and malignantly usurped the rights of the free beings of our galaxy and therefore, it is our unalienable right to abolish it from the galaxy. We believe that, should the rights of free beings be willfully and malignantly usurped, it is the unalienable right of said beings to alter or abolish said Government. We believe that the Galactic Government derives its power and right to rule from the consent of the governed. We firmly acknowledge the importance and necessity of the institution of Galactic Government. We, the beings of the Rebel Alliance, do this day send forth this Declaration to His Majesty, the Emperor, and to all sentient beings in the galaxy, to make clear to all the Purposes and Goals of this Rebellion.

Upon an Imperial overthrow during the early stages of Year 21, a new iteration of the Rebel Alliance spawned from the ashes to continue the fight against the Galactic Empire's cause. On Year 8 Day 98, the Rebel Alliance and the colossal SoroSuub Corporation merged to establish the New Republic. During its existence from Year -2 to Year 8, the organization served as the principal opponent of Empire. The Rebel Alliance was an idealistic organization that opposed the Galactic Empire and the tyranny that it considered it to be.
