Confederate Remnant

The Confederate Remnant consisted of the various disparate fragments of the Confederacy of Indpendent Systems that remained after the execution of the Separatist leadership, attempting to to preserve their independence from the Galactic Empire. It consisted of various independent worlds, and systems mostly in the Outer Rim Territories. Notable planets controlled by the Confederate Remnant were Geonosis, the capital of the Remnant, Mustafar, and Enarc.

At first the Confederate Remnant was composed of various warlords, all fighting the Galactic Empire, but after Gizor Dellso's victory against the 501st, they united under his banner, and drove off the armies of the Galactic Empire. They quickly raised armies of Battle Droids with amazing speed, and constructed many CIS warships to form the Remnant Navy.

History
With most of the Separatist leaders killed by Darth Vader during the massacre, as well as the deactivation of the battle droid armies, most of the Confederacy ceased to exist. However, various remnants managed to survive.
