Order 66
Profile
Order 66 is the recorded command that turned the Galactic Republic into the Galactic Empire in a single night. Through inhibitor chips, clone troopers across the galaxy were forced to execute their Jedi generals.
Decades of preparation
Long before the Clone Wars, the clones on Kamino had been outfitted with inhibitor chips that turned every clone into a sleeper-assassin against Jedi. Palpatine had planned this command from the beginning.
The night itself
At the end of Episode III, Palpatine speaks the words “Execute Order 66” through holo-communications. Within seconds, Jedi were killed on Felucia (Aayla Secura), Mygeeto (Ki-Adi-Mundi), Saleucami (Stass Allie) and Cato Neimoidia (Plo Koon).
Coruscant
On Coruscant, Anakin Skywalker, now Darth Vader, led the 501st Legion into the Jedi Temple. Padawans, Initiates and Sentinels were slaughtered. Only a handful — including Yoda, Obi-Wan Kenobi, Cal Kestis, Caleb Dume (Kanan) and Cere Junda — survived.
The survivors
Order 66 produced an entire generation of hidden Jedi: Quinlan Vos, Kelleran Beq, Kanan Jarrus, Cere Junda, Cal Kestis, Eno Cordova. The Inquisitorius was created to hunt these survivors.
Why it matters
Order 66 is the pivot of the whole saga. Without it, no Empire, no Vader, no Rebellion.
