The Hutt-Black Sun War was a war that was fought from 16 ABY to 20 ABY between the notorious crime empires the Hutt Grand Council and the Black Sun. Near the end of the war, the Black Sun's leader, Y'ull Acib, launched an attack on both Kolluga's Palace and Gunool's Palace. Kolluga managed to defeat Acib's forces at his palace, but Gunool was killed while hiding in his throne room on his palace. The war ended at the hands of the Galactic Republic when the two crime empires fought in Galactic City on Coruscant. Both of the lawless armies were crushed, bringing an end to the conflict.
