The tensions between the Republic and Separatists resulted in the Clone Wars. With the conflict being fought by clone troopers and battle droids, economically important planets like Ukio became targets. Despite having joined the CIS before the war, Ukio again became a granary for the Republic during the conflict. After fleeing the from the Battle of Scarif in 1 BBY, Princess Leia Organa ordered Rebel Alliance Captain Raymus Antilles to take her CR90 corvette, Tantive IV, to the planet Tatooine. In order to try and evade Imperial pursuit, Antilles followed no direct line and doubled back on himself during the journey, jumping first from the Scarif system to Ukio, and then on to Roon.
