After many unsuccessful attempts to bring change to the Empire as a senator, Princess Leia Organa became involved in the Rebel Alliance and immediately established herself as one of its most popular and influential leaders. Although it was extremely dangerous for someone of her prominence. Leia often participated in secret missions for the rebellion. It was during one such mission to recruit General Obi-Wan Kenobi that she obtained the technical readouts for the Empire's new Death Star battle station. Moments before being captured by Darth Vader, Leia hid the plans in the droid R2-D2, who then escaped to the planet Tatooine to find Kenobi.
