The Drummonds take their name from the lands of Drymen (or Drummond), in Stirlingshire, which they possessed prior to the 12th century. Sir Malcolm de Drymen, who supported Robert the Bruce, was instrumental in winning the Battle of Bannockburn by strewing caltrops (or spikes) on the ground thus disabling large numbers of the English cavalry. The 4th Lord Drummond became Earl of Perth in 1605. The Drummonds were intensely Jacobite in sympathy and King James VII conferred upon the Earl the Dukedom of Perth. The 3rd Duke was wounded at the Battle of Culloden while fighting in the Jacobite army. He later escaped to France. The Dukedom of Atholl was conferred on the 2nd Marquis. The dukedom became extinct on the death of the 6th Duke.
