Pompey reinstated Hyrcanus II as the High Priest but stripped him of his royal title, though Rome recognized him as an ethnarch in 47 BC.[16] Judea remained autonomous but was obliged to pay tribute and dependent on the Roman administration in Syria.

Several Hellenistic cities were granted autonomy to form the Decapolis, leaving the state greatly diminished.[2][17][18]
