When Senator Palpatine assumed the throne of galactic Emperor, he knew that the Jedi Knights were the only thing that could possibly stop his total control, so he sent a fleet of forces to exterminate all Jedi. He nearly succeeded, because the only Jedi that did survive were Darth Vader, Obi-Wan Kenobi, and Yoda. Yoda was the only true Jedi Master left. It is said that the best and truest Jedi Masters do not truly die, but move on to some mystical state of being.
