Confederacy of Independent Systems

The Confederacy of Independent Systems, also known as the Confederacy, the Separatist Confederacy, the Separatist Alliance, the Separatists; was the government and separatist movement led by Darth Sidious and his apprentice Count Dooku. Formed by various planetary and sectorial governments, as well as some mega-corporations, that declared intentions to leave the Galactic Republic, refusing to comply with its excessive taxation and corruption in the Senate during the Separatist Crisis.

Eventually, tensions between it and the Republic developed into war after Anakin Skywalker, Obi-Wan Kenobi, and Padmé Amidala were sentenced to execution on Geonosis and a group of Jedi led by Mace Windu attempted to rescue them. After the Republic revealed its clone army on Geonosis, the Separatists were forced to retreat, beginning a great war that would last for three years and tear the galaxy apart.

The CIS put fear in the hearts of countless citizens of the Republic, largely due to General Grievous, Supreme Commander of the Droid Armies. The Confederacy won many battles in the ensuing war but was dissolved when the Separatist Council leaders were killed on Mustafar, allowing Palpatine to reform the Republic into the Galactic Empire.
