To call something modern is to assert something fundamental about the social, cultural, economic and technical sophistication of that thing, over and against what has come before. A Cultural History of Theatre in the Modern Age provides an interdisciplinary overview of theatre and performance in their social and material contexts from the late 19th century through the early 2000s, emphasizing key developments and trends that both exemplify and trouble the various meanings of the term 'modern', and the identity of modernist theatre and performance. Highly illustrated with 40 images, the ten chapters each take a different theme as their focus: institutional frameworks; social functions; sexuality and gender; the environment of theatre; circulation; interpretations; communities of production; repertoire and genres; technologies of performance; and knowledge transmission.
