History
"You are on the Council, but we do not grant you the rank of Master.''" "''What? How can you do this? This is outrageous, it's unfair."

- Anakin Skywalker is denied mastery.

Yoda was one of the oldest Jedi Masters, having lived approximately 900 years before his death.

The Jedi Council was made up of twelve Jedi Masters, one of which bore the title of Grand Master, and who had the power to grant others the title of Master in consensus. Other prominent Jedi Masters on the Council included Mace Windu and Shaak Ti.

After serving as a Jedi Knight for many years, the training of Anakin Skywalker advanced to the point that he felt he deserved the rank of Jedi Master, thought the Council did not agree. When Sheev Palpatine appointed Skywalker as his personal representative to the Council, they reluctantly agreed, hoping to use him as a means to spy on Palpatine, but did not grant him the title of Master, which outraged him.
