Colonel M Wilks writes to Lord Powis (Home Office) in 1812 detailing the Duke of Atholl's repeated attempts to undermine the Isle of Man's constitutional rights and legislative independence since the 1765 Revestment. Wilks chronicles failed Parliamentary bills (1780–1783), the Duke's appointment as Governor (1792–93), efforts to control the Lieutenant Governor position, and current threats to the House of Keys' autonomy and property rights. The letter appeals for intervention to protect Manx constitutional liberties from aristocratic overreach.
