Augusto Boal's Theatre of the Oppressed emerged in 1970s Brazil as a response to political oppression. This innovative approach uses theater as a tool for social change, empowering marginalized communities through active participation and dialogue. Key techniques include Forum Theatre, Image Theatre, and Invisible Theatre. These methods transform spectators into "spect-actors," encouraging them to intervene in performances and explore solutions to real-life issues, fostering critical thinking and collective problem-solving.
