A comprehensive historical narrative of the 1765 Isle of Man Revestment, covering the death of the 2nd Duke of Atholl, negotiations between George Grenville's Ministry and the 3rd Duke, the Crown's purchase of sovereignty for £70,000 and a £2000 annuity, and subsequent disputes over compensation. The chapter details the smuggling crisis, parliamentary acts suppressing illicit trade, and the 4th Duke's failed attempts (1781-1805) to obtain additional compensation.
