Order 66

Order 66 was a secret command given in the Star Wars universe. It activated a mind control chip planted in the heads of the Clone army and ordered the execution of all Jedi. The order was activated by Chancellor Palpatine, who was secretly the Sith Lord Darth Sidious. Most of the Jedi across the galaxy suffered extermination, leading to the end of the Jedi Order. This allowed Palpatine to turn the Galactic Republic into the Galactic Empire.

Very few Jedi survived Order 66. Notable examples include Obi-Wan Kenobi, Yoda, Ahsoka Tano, Grogu, and Cal Kestis.
