When Rome invaded Palestine and Pompey took Jerusalem in 63 B.C.E., the Romans gave the Jewish leaders in Jerusalem some limited authority over their own religious affairs and this lead to the formation of the Sanhedrin. To many Galileans, their religious leaders in Jerusalem had "sold out" and were in cahoots with the Romans, and these Galileans despised these religious leaders in Jerusalem. The Galileans were ready to revolt against Rome, as they had done earlier against the Seleucids.
