Jedi

"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 The Jedi (or Jedi Order, later known as the Old Jedi Order) are a monastic spiritual organization in the Star Wars universe.

Description
As depicted in the franchise's canon, Jedi knights study, serve and use a mystical power called the Force, and their traditional weapon is the lightsaber, which emits a controlled plasma flow in the shape of a sword, in order to serve and protect the Galactic Republic and the galaxy at large from conflict or governmental instability. As guardians of peace and justice in the galaxy, they mediate peace negotiations among planets and other factions and, if necessary, use their formidable fighting skills, agility and wisdom to quickly end unrest or neutralize dangerous individuals or threats.

The Jedi are governed by a Council, consisting of twelve of the most powerful and wise members of the Jedi Order. They are bound to a code of ethics, morality, principles and justice. The Jedi are trained to use the Force through passive meditation, practicing selflessness, and commitment to justice while at the same time rejecting emotions such as fear, anger and hate. Their way of life contrasts with their archenemies, the Sith, another monastic organization who use the dark side of the Force to achieve their goal of ruling the galaxy.

The leader of the Jedi Order, and head of the Jedi Council, who's title is Grand Master or Master of the Order.
