Edward Marcus Despard (1751 – 21 February 1803), an Irish officer in the service of the British Crown, gained notoriety as a colonial administrator for refusing to recognise racial distinctions in law and, following his recall to London, as a republican conspirator. Despard's associations with the London Corresponding Society, the United Irishmen and United Britons led to his trial and execution in 1803 as the alleged ringleader of a plot to assassinate the King.
