[Star Wars] How many Jedi survived Order 66?
gpt
Technically, Order 66 never ended. Order 66 became a standing order to kill Jedi on sight for the entire Empire, though mostly it pertained to the Stormtroopers. But you're obviously asking about the initial order, so I'll stick with that.

The highest estimates put the number of Jedi that survived at less than 100. In actuality there were probably less than 50. A vast majority of Jedi were at the Temple when it was sacked, and the rest were all in the field with the Clone Army. The thing is, the few that did survive became targets. Half of the Galaxy thought that they had betrayed the Republic and its people, and would have gleefully turned in any Jedi they knew of. Of the 50 or so that survived the initial purge, almost all of them were hunted down and slaughtered in the following few years.

It was eventually left with only a small number, 2 or 3 perhaps, unaccounted for. We're still not sure what happened to them, but they're likely long dead by now. It's been decades.
