Jedi Knight

"For over a thousand generations, the Jedi Knights were the guardians of peace and justice in the Old Republic. Before the dark times... before the Empire."

- Obi-Wan Kenobi, to Luke Skywalker

Jedi Knight was a rank within the Jedi Order, referring to Jedi who had completed their training and passed the Jedi Trials to become a full member of the Order. Jedi Knights, like the Order they served, were guardians of peace and justice in the Galactic Republic, and served in key military command roles during the Clone Wars. At the war's end, Supreme Chancellor Sheev Palpatine&mdash;secretly the Sith Lord Darth Sidious&mdash;issued Order 66. With the order, the clones of the Grand Army of the Republic killed the Jedi as traitors, wiping out most of the Jedi Knights. At the end of the Galactic Civil War, Luke Skywalker was the last known Jedi Knight.
