Discovered between 5,000 and 3,000 BBY, Aralia was inhabited by Humans who joined the Galactic Republic sometime during the Great Sith War. When the Jedi Civil War erupted a few decades later, Aralia was located deep in space controlled by the Sith Empire of Darth Revan. The planet would remain in Sith-controlled space until the end of the New Sith Wars, when the Brotherhood of Darkness was defeated by the Army of Light. With the Ruusan Reformation of the Republic passed, Aralia rejoined the Republic and the world flourished.
Under the government's new reforms, spice-trade was outlawed and smuggling the substance was made a capital offense in 980 BBY. Aralia continued to see success as a resort world, but suffered a setback circa 200 BBY when a spice-smuggler crash-landed in the jungles. On board the ship was a nest of Ranats, a mildly-intelligent species which had evolved on the planet Rydar II. Calling themselves the Con Qeecon or "the conquerors", the Ranats quickly multiplied and began building their underground maze of warrens. Infesting the ground and depleting the food supply of many of the native wildlife, the Ranats became more of a nuisance then a welcome co-inhabitant of the world.
Joining the Confederacy of Independent Systems during the Clone Wars, the planet was subjugated by the Galactic Empire when the CIS was defeated. Under Imperial rule, the Human inhabitants initiated Project Aralia, a massive amusement park designed to boost the economy on Aralia. During this time, the Ranat colonies, which each maintained a population of one hundred individuals, began to interfere in the construction of the massive park. Angered, the Humans called for their eradication and the Empire obliged. The Imperial governor issued a decree stating that Ranats could be killed in self-defense and that they were barred from purchasing or owning weapons. Darth Vader personally helped to drug groups of Ranats and use them as guards for some of the extermination camps built on the planet.
During the Galactic Civil War, after Vader and Emperor Palpatine's deaths, Aralia and the surrounding space were reorganized into the Greater Maldrood territory by Admiral Treuten Teradoc. When the New Republic encroached on his borders, Teradoc fled and the Maldrood fell; though many of its worlds, including Aralia, remained independent from the Republic. Surrounding systems fell in following years to the invasion of the Yuuzhan Vong, cutting of Aralia from all offworld contact. Whether it joined the Galactic Alliance after the war is unknown; though it was a member state of the Galactic Empire of Darth Krayt.
