The Knights Templar and the Knights of the Temple

The Knights Templar, there were monks that basically guarded a passage from Jaffa to Jerusalem. They were pretty rough apparently and they at one point discovered King Solomon's riches in the temple. One theory is that after they were released from prison, they went into hiding and emerged as Freemasons later on. And King Philip the fourth may or may not have had them arrested on a Friday the 13th.
