The earliest generals fought in the Mandalorian Wars as Revanchists, opposing the Neo-Crusader invasion. The end result was them falling to the dark side and forming a Sith Empire. During the Great Galactic War and following Galactic War, many Jedi led Republic troopers into battle against the reconstituted Sith Empire. Jedi were assigned to serve as generals (some as Lords) of the Army of Light during the New Sith Wars. Most of those still alive by the Seventh Battle of Ruusan perished in that battle.
