The Onderon Royalists were those people and factions on Onderon that supported Queen Talia Kira over her cousin General Vaklu during the Onderon Civil War. They succeeded in ending the Onderon Civil war at the Second Battle of Onderon, commanded by Meetra Surik and supported by the Galactic Republic and the Mandalorians, where they claimed victory over the Onderon separatists, who were backed by the Sith Triumvirate.
