330 p., This dissertation examines the major works of Trinidad-born playwright Mustapha Matura, dealing with plays written from 1970 to the present. By considering the relation of Matura's work to Britain and Trinidad, it explores the complexity of identity performance in postcolonial theatre and the ongoing need for agency among diasporic communities. Postcolonial scholarship fully recognizes the significance of writing in the development of postcolonial identities, yet dominant postcolonial theory largely excludes theatre from discussions of that development. Given its aural and visual presentation and its immediate interaction with an audience, theatre provides a unique postcolonial moment through which audience members can survey issues of race and place in their lives.
