The document provides background information on John Osborne's 1956 play "Look Back in Anger". It introduces the two main motifs of the "Angry Young Man" and "Kitchen Sink Drama". The play was groundbreaking for depicting the domestic lives and raw emotions of the working class in postwar Britain. The main character, Jimmy Porter, came to epitomize the disaffected youth of the time and their anger towards the declining British class system and empire. The play captured the mood of social change in 1950s Britain.
