Templar (n.)

late 13c., from Anglo-French templer, Old French templier (c. 1200), from Medieval Latin templaris (mid-12c.), member of the medieval religious/military order known as Knights Templars (c.1118-1312), so called because they had headquarters in a building near Solomon's Temple in Jerusalem (see temple (n.1)). Their distinguishing garb was a white mantle with a red cross.
