In common with other critics of the Tory administration of the day, Shelley despised above all Robert Stewart, Viscount Castlereagh, though there is nothing to suggest that the latter had any specific role in the Peterloo Massacre in August 1819, when military forces fired on a Reform meeting in Manchesteran event that stirred Shelley to write The Mask.
