In the 1667 former Lord Chancellor Edward Hyde, earl of Clarendon was impeached by the House of Commons. Having carefully analyzed the text of the blame the author comes to conclusion that the charge was fabricated and pursued two main aims: firstly, it was directed to destroy a reputation of Clarendon and thereby negate his influence in the House of Lords, secondly, it was directed to blamed him for mistakes of the government and so legitimated the current power. It also investigates the genealogy of this charge which succeeded to some other charges in high treason.
