Early in the 20th century, street theatre developed as a means of emancipating the working class and bolstering the revolt against established authority. Its journey in India started with left-wing theatre activists leading the anti-colonial movement. Although street theatre and folk theatre are closely related, street theatre is more of a participatory social communication process than a straightforward artistic medium. With an emphasis on the "Halla Bol" movement, this intellectual examines the function and possibilities of street theatre as a vehicle for community development intended to bring about social change. Safdar Hashmi and the Jana Natya Manch theatrical company spearhead the "Halla Bol" movement, marking a turning point in the history of Indian street theatre. Hashmi's work best demonstrated the use of theatre for social transformation and political activity. His terrible martyrdom during a rendition of "Halla Bol" highlighted the dangers that musicians who question the status quo confront. The audience responded strongly to Halla Bol's themes of labor rights, gender equality, caste prejudice, and governmental corruption, which democratized theatre and inspired activists of later generations. The Indian People's Theatre Association's tenets influenced Jana Natya Manch, a pioneer of contemporary Indian street theatre in this succinct case study. It examines the effects of street plays in contrast to traditional proscenium theatre, as well as their future potential. The participatory style of street theatre, as well as Halla Bol's legacy, demonstrates its transformational potential and ongoing importance in promoting social justice.
