Theatre historians are now reconsidering traditional attitudes towards ‘theatre riots’ of the past, in the light of the new perception of ‘mob’ activity pioneered by the social historian George Rudé. Here, Athenaide Dallett looks at two more recent audience revolts – the well-documented riots at the opening of Synge's The Playboy of the Western World in Dublin in 1907, and the indignant response of Berkeley students in 1968 to the Living Theatre's presumption in Paradise Now, in lecturing them about a revolution already taking place on the streets. In both cases, she suggests, riots were provoked by a breach of the contract between performers and audience, taken as legitimating a revolutionary response by such social theorists as Locke and Rousseau. Athenaide Dallett, who recently gained her doctorate from Harvard, teaches at the University of Connecticut at Torrington, and is currently working on a study of the connections between political philosophy and theatre.
