Grand Master

Grand Master was a title bestowed on the oldest and wisest member of the Jedi Order. Whereas the Master of the Order served as leader of the overall Order, the Grand Master was the head of the Jedi High Council&mdash;the Jedi's highest governing body. Yoda, a Jedi Master who had lived for over eight centuries by the time of the Clone Wars, was the Grand Master of the Jedi Order during the waning years of the Galactic Republic.

Roles and powers
The Grand Master oversaw the Jedi High Council, a body of twelve Jedi Masters that oversaw and governed the activities of the Jedi Order. The title of Grand Master was reserved for the oldest and wisest living Jedi Master. It was distinct from the office of Master of the Order, the holder of which led the Jedi Order as a whole. However, it was possible for a single individual to hold both titles at the same time.

History
During the Clone Wars, the title of Grand Master was held by Yoda. After the Dark Lord of the Sith Darth Sidious managed to kill the majority of Jedi throughout the galaxy, the Grand Master went into hiding on the planet Dagobah. He remained there for over twenty years, until Luke Skywalker came to him for training. Skywalker was trained under the guidance of Grand Master Yoda, who became one with the Force about a year later.
