Naboo was a peaceful planet on the edge of the galaxy inhabited by humans and Gungan. It was the home planet of Emperor Palpatine, Padme Amidala and Jar Jar Binks.
Padme Amidala - later Queen Amidala - became the secret wife of Anakin Skywalker and mother to both Leia Organa and Luke Skywalker.
Naboo was first blockaded, then invaded by the Trade Federation but thanks to the efforts of their Space Fighter Corps and Anakin Skywalker, the Federation were defeated.
Later, following the death of Queen Amidala, the Empire effectively ruled Naboo through the consent of Queen Apailana, but she secretly had doubts and harboured an number of Jedi on the planet. This led to her assassination in 18BBY by Empire troops.
The news of the destruction of both Death Stars and the death of Emperor Palpatine was welcomed by Queen Kylantha, and eventually an uprising freed Naboo from Imperial rule.
