This thesis explores to role of theatre in the lives of criminalized women. It seeks to better understand the ways in which theatre initiatives can be used as a tool for participants through various means, such as potentially being a form of self-expression, or a way to gain voice. This exploration was facilitated by conducting a case study of the Clean Break Theatre Company, a theatre company for criminalized women in London, England. Data was collected through performance and course observations and interviews with twelve women. The final themes shape the exploration as participants identify the importance of self expression through theatre, and its ability to aid in personal transformation or growth. Theatre initiatives are important because they create a unique lens into the experiences of these women, as well as being used as a tool for change in their lives.
