Bail Organa's resistance movement (Earth-2042)

During the early days of the Galactic Empire, Senator Bail Organa formed a resistance movement. The movement helped form some of the earliest organized resistance groups by using the power and wealth of Alderaan, which included royal and personal fortunes. Organa was able to bring about firepower and other difficult to obtain assets, and his movement actively recruited similarly-minded individuals after a thorough vetting process. It later became one of the founding members of the Alliance to Restore the Republic through the Corellian Treaty.
