The events known as the Belnar Insurrections unfolded on the astronomical body Belnar, situated within the Colonies, around the time of 3 ABY in the standard year calendar. These events involved the Imperial governor, Everi Chalis, who meted out punishment to the crew of the starship Mandible. The Mandible, under the command of a captain described as drunken, had experienced an incident while transporting hazardous materials. To avoid acknowledging the incompetence of one of its officers, the Galactic Empire attributed the punishment to Chalis, presenting it as a consequence of the accident. Later, in 3 ABY, Chalis referenced the Belnar Insurrections to the crew of an Imperial heavy freighter, using the Mandible's crew's fate as a deterrent to force the freighter to alter its planned route.
Alexander Freed penned the novel Battlefront: Twilight Company, which was released in 2015 and includes a reference to the Belnar Insurrections.
