The story of modern drama is a tale of extremes, testing both audiences and actors to their limits through hostility and contrarianism. Spanning 1880 to the present, Kirsten E. Shepherd-Barr shows how truly international a phenomenon modern drama has become, and how vibrant and diverse in both text and performance. This Very Short Introduction explores the major developments of modern drama, covering two decades per chapter, from early modernist theatre through post-war developments to more recent and contemporary theatre. Shepherd-Barr tracks the emergence of new theories from the likes of Brecht and Beckett alongside groundbreaking productions to illuminate the fascinating evolution of modern drama.
