This essay focuses on a programme of a Shakespearean revue entitled ‘This Sceptred Isle’ (1941) in the possession of the Wolfson Centre for Archival Research, Library of Birmingham. Billed as a ‘Dramatisation of Shakespeare’s Call to Great Britain in Time of War’, the show was a brainchild of eminent Shakespeare scholar G. Wilson Knight (1897–1985) and featured such warlike set pieces as ‘This England never did, nor never shall, / Lie at the proud foot of a conqueror’ (King John) and John of Gaunt’s ‘this sceptred isle’ oration (Richard II). Knight performed all the main roles. He was convinced of Britain’s imperial destiny and of the central importance of Shakespeare (‘a national prophet’) in it. Indeed, Knight’s interpretation of the playwright informed his wartime assertion about Britain’s imperial mission and the significance of the monarchy. ‘This Sceptred Isle’ was, however, hardly a typical piece of British wartime propaganda, considering that its creator was an admirer of Nietzsche, whose ideas were appropriated by Nazism. This essay aims to explore Knight’s idiosyncratic thinking underlying the programme of ‘This Sceptred Isle’ in order to clarify how the admirer of Nietzsche and Nazism created a polemics of British patriotism with recourse to Shakespeare.
