History
Aleen was discovered by Galactic Republic scouts during the Great Manifest Period. Granted direct representation in the Galactic Senate; the world was represented by Senator Bogg Tyrell during the waning days of the Republic.

Over the years aligned with the Senate, the world welcomed the construction of a chapter house of the Jedi Order. The world was known to have produced at least two Jedi Masters, Tsui Choi and Kazdan Paratus, who both served during the Clone Wars.

Behind the scenes
Due to the discrepancies between the previous sources and the planet described in The Clone Wars TV series, Jason Fry stated that those Aleen are two different worlds. The old Aleen is now Aleen Minor and the new is Aleen. This was later formalized in The Essential Atlas Online Companion.
