Queen Amidala/Padmé Naberrie Information
In The Phantom Menace Queen Amidala is played by two people, herself and her body-guard, Sabé, who acts as her decoy. Queen Amidala also acts as Padmé Naberrie during danger.

Queen Amidala:
"Amidala rules as Queen of the Naboo people at the age of only 14. She was raised by humble parents in a small mountain village, where her exceptional abilities were recognized early in life. Given the best raining and pushed to develope her capabilities, she became Princess of Theed, the Naboo capital city at the age of 12. Amidala was elected Queen upon the abdication of the previous sovereign, Veruna, who had become enbroiled in outworld politics after a rule of 13 years. The Naboo trusted that Amidala would hold their interests close to her heart-but had no idea of the crisis looming ahead."

Amidala's status of Queen forces her to wear very formal clothing.

Padmé Naberrie:
"Whenever the Queen is exposed to danger, she disguises herself as one of her own handmaidens, taking the name Padmé Naberrie. The identical hooded dresses and similar appearance of Amidala's handmaidens make it easy for Padmé to appear and disappear quietly from the group. When Padmé is among the attendants, handmaiden Sabé impersonates the Queen, subtly taking signals from Padmé regarding royal decisions. Captain Panaka is behind the creation of Amidala's double identity, having explained the old Palace scheme to her upon her coronation. In her guise as Padmé, Amidala accompanies Qui-Gon Jinn to Mos Espa to see for herself what the Jedi is up to."

Star Wars Data Bank:
"Born Padmé Naberrie, Queen Amidala was the formal name of the royal leader of Naboo. As a child, Amidala was prodigiously talented and extremely well educated. She had long been interested in public service, volunteering in the Refugee Relief Movement as a youth. Her efforts helped in the Shadda-Bi-Boran exodus. At the age of eight, she joined the Apprentice Legislature and became an Apprentice Legislator at age 11. By 14, she was elected Queen of Naboo.

During the Trade Federation siege of Naboo, the scheming Neimoidians tried to force the strong-willed Amidala to sign a treaty that would legitimize a brazenly illegal occupation. Amidala refused, and was sentenced to a prison camp. En route to incarceration, Amidala was freed by Jedi ambassadors. They took the Queen and part of her retinue to Coruscant, to plead her case before the Senate with the help of Naboo's galactic representative, Senator Palpatine.

On Coruscant, Amidala learned of the inefficiencies of galactic politics, watching as Trade Federation political maneuvering stalemated her plea. Following advice from Senator Palpatine, Amidala called for a Vote of No Confidence in Supreme Chancellor Valorum.

Fed up with the Senate, Amidala returned to Naboo. She requested aid from the native Gungans in freeing her captured capital. During the Battle of Naboo, Amidala infiltrated her own palace, and forced Neimoidian Viceroy Nute Gunray to end the occupation. The cowardly Neimoidians, having their armies defeated, capitulated and freedom was brought back to Naboo.

While Queen Amidala was the ruler of Naboo she had a large staff of advisors and aides that handled the day-to-day affairs. Sio Bibble, for instance, was Naboo's governor. Captain Panaka was Amidala's loyal bodyguard and head of security. Ric Olié was the pilot of the Queen's gleaming Royal Starship and leader of Bravo Flight.

Perhaps most important in Amidala's entourage were her five handmaidens. Saché, Yané, Rabé, Sabé and Eirtaé not only helped the Queen with her intricate gowns, hairstyles and make-up, but they were also trained in self-defense. When in danger, Queen Amidala disguised herself as one of her handmaidens, and adopted her less formal name of Padmé. When disguised as Padmé, Sabé assumed the role of Queen in her place."
