Blockade of Bosph
During the reign of the Galactic Empire the planet of Bosph in the Outer Rim Territories was blockaded and quarantined by the Imperial Navy. The blockade was put in place after Galactic Emperor Palpatine became aware of the fact that planet's Bosph species were controlled by a Force-sensitive government. The blockade began shortly before the Bombardment of Bosph and both events were orchestrated by the sector's Moff, a Human named Harsh. Those few Bosph who survived the orbital bombardment of the planet were almost all kept on their devastated homeworld by the bombardment although a few did escape. All Bosph, including those trapped, took up a policy of dis-remembrance toward the Empire meaning they refused to acknowledge it's existence, including the existence of the blockade.
