The Alderaan sector, a sector found within the Core Worlds area of the galaxy, is the focus of this article.
Most notably, this sector included the planet Alderaan, a tranquil and powerful world that faced destruction at the hands of the Galactic Empire. Within the Senate of the Galactic Republic, the sector was represented by prominent Alderaanian individuals like Bail Antilles and Viceroy Bail Organa. Organa remained the sector's representative in the Imperial Senate; he was later succeeded by his daughter, Princess Leia Organa, who would later represent the sector in the restored Galactic Senate of the New Republic.
