During the 1790s, political speech in London's public spaces and commercial sites of leisure came under intense governmental surveillance. Fearing revolutionary infection from across the channel in France, the Pitt ministry sent spies into popular organizations such as the London Corresponding Society and turned more attention to other sites as well, including coffeehouses, taverns, debating-club rooms, and the street. Recently, historians too have explored the ways in which radicals manipulated the ludic vocabularies of urban sociability to critique the regime, protest persecution, and argue for reform. In this article I address a site that figured prominently as a place for radical speech in the 1790s: the Theatre Royal at Covent Garden. Although it was a site whose content was strictly regulated by the state through the office of the Examiner of Plays, the royal theater was, like other eighteenth-century theaters, a place where performances multiplied: viewers watched the play, but in the well-lit and noisy pit, boxes, and galleries, they watched other viewers intently. All were engaged in a complex process of performance, reception, and counterperformance. Indeed, as scholars have shown, theater audiences in late Georgian London were highly skilled at appropriating a theatrical grammar by which to demand their perceived rights as English subjects. Such strategies revealed the potency of theatrical representation in a society where, as Gillian Russell notes, “performance, display and spectatorship were essential components of the social mechanism.”
