Princess Leia Organa of Alderaan, often referred to as simply Princess Leia, is a fictional character in the Star Wars universe. She is one of the main protagonists of the original Star Wars trilogy. She is one of the leaders of the Rebel Alliance, fighting against the Galactic Empire, and recruits some of its most important members: Luke Skywalker, Han Solo, Chewbacca, Obi-Wan Kenobi and Lando Calrissian.
In Return of the Jedi, it is revealed that she is the twin sister of Luke Skywalker, and thus the daughter of Darth Vader. In the Star Wars prequel films, her mother is identified as Padme Amidala; her adoptive father is Bail Organa, who is depicted as the head of Alderaan's royal family and a supporting character in the prequels.
