Public Theatres and Theatre Publics presents sixteen focused investigations that connect theatre and performance studies with public sphere theory. The organizing critical lens of publics and publicness allows for the chapters to speak to one another other across time periods and geographies, inviting readers to think about how performing in public shapes and circulates concepts of identity, notions of taste or belonging, markers of class, and possibilities for political agency. Each essay presents a theorized case study that grapples with fundamental questions of how individuals perform in public contexts. The essays, written by a cross-section of prominent and emerging theatre and performance scholars, contribute new discussions and understandings of how theatre and performance work, as well as how publics, publicity, and modes of publicness have been constructed and contested over the last three centuries and in multiple national contexts including the US, Britain, France, Germany, Argentina and Egypt.
