I consider the Templars as the first of the holy orders; so feared that the French King Philip le Bel concocted spurious charges in order to detain every Templar knight he could get to - just to avoid having to pay the Order back the funds he'd borrowed. Not that it did him any real good...he was dead within a year after burning the last Templar Grand Master, Jacques de Molay, at the stake for heresy. De Molay is said to have cursed both the King and the Pope, and they both had died within a year.
The Tuesday after next will mark the 700th anniversary of de Molay's death.
