The Clone Wars (22 BBY–17 BBY), also known as the Clone War and the Great Clone War, was the name given to the major galactic conflict fought between the Galactic Republic and the Confederacy of Independent Systems. The war was named after the clone troopers utilized by the Republic against the battle droid forces of the CIS. These armies were two of the largest ever pitted against each other in galactic history, and the fighting between them rapidly spread to countless inhabited worlds. Both sides scored significant victories over the other, and at different times during the war either seemed likely to triumph.
