Confederacy of Independent Systems (Earth-2356)

The Confederacy of Independent Systems (CIS), also known as the Separatist Alliance, the Separatist State, and commonly referred to as the Separatists, was a partially recognized galactic government that controlled a portion of the Mid Rim and the Outer Rim. Formed by thousands of secessionist star systems on the grounds of excessive taxation and corruption within the Galactic Senate, the Separatists were led by the ellusive rogue Jedi organization known as the Akatsuki, whose leader, Pain, served as the Alliance's Head of State. In addition the Separatists were secretly supported by several corporations, including the Trade Federation, headed by Viceroy Ord Casto, the Techno Union, led by Wat Tambor, the Retail Caucus, the InterGalactic Banking Clan, led by San Hill, the Commerce Guild, and the Corporate Alliance.
