The Maccabees did not reestablish the old order of priesthood, which gave rise to the Teacher of Righteousness and the Essenes. While generally believed to be centered on Qumran, the sect had followers all around Judea. Authorship of the Dead Sea Scrolls is not universally accepted to have been the Essenes alone - although it seems to me any other alternative is similar to shovelling smoke...
There was an Essene Gate built by Herod in the SE corner wall of Jerusalem.
