In the seventeenth century, interest in Templarism became political after the execution of Charles I, with the idea that Stuart partisans invented a Templar degree, as the king's death was to be avenged, as was the violent death in 1314 of Jacques de Molay, last Grand Master of the Templars. The story told by Dom Calmet was that Viscount Dundee was supposed to have been an early Templar Grand Master and to have fallen at Killiecrankie wearing the Grand Cross of the Order. The Duke of Mar is then said to have held office, after which time the Templar Order was apparently inactive until its revival by Charles Edward Stuart in 1745. An original letter of the 3rd Duke of Perth to Earl of Airlie Lord Ogilvy shortly after the Jacobite victory at Prestonpans, described a secret ceremony at Holyrood in which the prince was elected Grand Master of the ancient chivalry of the Temple of Jerusalem on Tuesday 24 September 1745.
