Antar 4 was a moon located in the Mid Rim of the galaxy. During the Separatist Crisis, a schism erupted between citizens loyal to the Galactic Republic and those aligned with the Confederacy of Independent Systems. The moon fell to the Separatists during the Clone Wars. After the war, as retribution for the moon's support of the Separatists, the Galactic Empire engaged in mass arrests and executions on Antar 4, in what became known as the Antar Atrocity.
