- "…very simply this, that Naboo represents the best of the old Republic."
- ―Leia Organa, to Queen Soruna
- "If I grew up here, I don't think I'd ever leave."
- ―Anakin Skywalker, about Naboo
Naboo was a small pastoral world located near the border of the Outer Rim Territories. Naboo did not have a molten core, instead it was comprised of a flooded cave network. Its surface comprized a vast array of different landscapes, from rolling plains and grassy hills to swampy lakes. Beside its natural features, Naboo was considered a world of classical beauty due to the aesthetics of its population centers. The porous crust contained plasmic energy that was harvested for energy and building material.
While most of Naboo's land animals were peaceful, as exemplified by the gentle shaak, the planet's oceans teemed with menacing creatures, such as the opee sea killer and the sando aqua monster.
- "It is an honor to be here for this momentous occasion. The pride I feel for this planet cannot be put into words. Eight-hundred and forty-seven years ago Naboo joined the Republic. And tonight we celebrate that reunion."
- ―Palpatine giving a speech during the Festival of Light
Originally, Naboo was home to the reptilian Elders and the amphibian Gungans. Eventually the Elders went extinct, and a group of human colonists from Grizmallt crashed on Naboo. Led by Kwilaan, they ventured into the Gallo Mountains, created a farming community at the Dee'ja peak, establishing their presence on the planet and eventually taking its name for themselves. Tensions arose between the two peoples, and they started separate and apart from that point on.
Some eight-hundred and forty-seven years before the Clone Wars, Naboo joined the Galactic Republic, the democratic union that sought to govern the galaxy. The people of Naboo celebrated this event during the Festival of Light.
About ten years before the Clone Wars, Naboo was blockaded and invaded by the Trade Federation. The 14-year-old Padmé Amidala, who had recently been elected Queen of Naboo, guided her home planet through the invasion and sealed a new friendship with the Gungans. In an upsurge of sympathy and solidarity toward the invaded planet, the queen's emissary in the Galactic Senate, the seemingly unassuming Senator Sheev Palpatine, was made Supreme Chancellor of the Republic.
Some twenty days after the Battle of Endor—which resulted into the defeat of the Empire by the Alliance to Restore the Republic—the Royal House of Naboo received the visit of Princess Leia Organa of Alderaan, who had been sent by Mon Mothma, Chancellor of the Alliance. In the royal palace's throne room, Organa met the then-Queen of Naboo, Sosha Soruna, and asked for Naboo's support in the establishment of a New Republic and the restoration of the Senate. The queen heartily accepted Organa's offer, claiming that the Naboo felt great shame over Palpatine's actions.
During the meeting, gigantic storms suddenly began to rage, and Naboo's orbital sensors were all jammed. The Empire had set up a climate disruption array in orbit, as ordered by the late Emperor Palpatine. Named Operation: Cinder, the Empire's plan was to disrupt Naboo's environment and climate, and thus render the planet inhospitable. The storms caused fires and flooding across the world, and many buildings were demolished. Soruna, Organa, and Alliance pilot Shara Bey finally decided to use three old N-1 starfighters—that had been stored by Queen Neeyutnee in the palace's hangar during the Clone Wars—and go protect Naboo by destroying the Empire's satellites. Once in space, the three women were attacked by a squadron of TIE fighters, but managed, nonetheless, to knock out all of the satellites. A Rebel fleet led by Lando Calrissian and Nien Nunb soon arrived to take care of the Imperial forces.
Due to the fact that Naboo had been the Emperor's homeworld, the planet became a rallying point for Imperial sympathizers. Months after the failed Operation: Cinder, the Imperial Navy deployed three attack forces to wipe out the New Republic's presence in the Naboo system. However, these attempts were successfully foiled by Corona Squadron.
Naboo was inhabited by two societies: an indigenous species of intelligent amphibians called the Gungans and a group of peaceful humans who were referred to as the Naboo. In the distant past, a cultural misunderstanding resulted in a serious quarrel between the Gungan and the human colonists. Both sides refused to acknowledge their responsibilities in the rift, and the two groups ostracized each other for the longest time. That situation lasted until the Invasion of Naboo by the Trade Federation forced the humans and Gungans to join forces.
