Republic Jedi Order

The Republic Jedi Order was an ancient organization of Jedi that were founded long ago. They remained affiliated with the Galactic Republic until the First Order-Republic War, where the last few active Jedi joined the First Order under the monicker "The Knights of Ren" while Luke Skywalker cut himself off from the Force and hid in exile on Ahch To.

The Order was ultimately destroyed when Darth Amorosa killed Kylo Ren.

It was succeeded by the new Jedi Order.
