A theocracy is a form of governance where religious figures hold power and base their decisions on religious principles. The world of Nazzri, a planet inhabited by the Nazzar species, was governed by a theocratic oligarchy in the era preceding the Great Sith War. Furthermore, the Yuuzhan Vong empire operated as a theocracy.
The individuals participating in the Anti-Sith conspiracy viewed the Galactic Empire under Palpatine and Darth Vader as a Sith-controlled theocracy. Subsequently, during Operation Shadow Hand, the cloned Palpatine planned to transform the Empire into an actual theocracy rooted in the dark side of the Force.
