Rob Roy became an outlaw when a dispute over money and cattle led him into a life of banditry and cattle rustling aimed at local landlords and nobility. Eventually, having taken up the Jacobite cause, supporting the Stewarts against the English Crown, the label of treason - and a price - was put on his head.
Despite all this, Defoe's book, Highland Rogue, led to a Royal Pardon in 1726. Rob Roy spent the rest of his days in the tiny hamlet of Balquhidder. He died of old age and is buried among MacLarens and MacGregors in the graveyard of the Old Kirk.
