A Jedi General was a high-ranking Jedi military officer in the Grand Army of the Republic. This title was created in 22 BBY, shortly after the Clone Wars began, and was reserved for Jedi Knights, Jedi Masters, and the Jedi High Council—the governing body of the Jedi Order. As generals, the Jedi were responsible for leading the Galactic Republic's clone troopers against the forces of the Confederacy of Independent Systems.
