Discovered during the Great Manifest Period by the Galactic Republic, the world remained loyal to the Galactic Senate for centuries. In 19 BBY, upon the Republic's transformation into the Galactic Empire, Ansillivog pledged to follow Emperor Palpatine's rule as Governor Dermeg was appointed to the system. Playing no role in galactic politics throughout the Galactic Civil War or Imperial Civil War, the world would eventually fall under control of the New Republic. Surviving the Yuuzhan Vong War and Second Galactic Civil War, Ansillivog became a member of the Empire of Darth Krayt circa 137 ABY.
The planet Ansillivog was created for the second edition of the Star Wars: The Roleplaying Game, published in 1992. It was later listed on a coordinates map in the The Essential Atlas.
