This chapter explores the history of representations of race in the Irish theatre, with a particular focus on blackface and minstrelsy – a discussion which uses at is focal point the pre-histories and afterlives of Dion Boucicault’s 1859 play The Octoroon. That melodrama is resituated within an Irish performance tradition (one that Boucicault himself would have encountered as a young man in Dublin) that stretches from the late nineteenth century, and which involved the performance on Irish stages of African-American characters – whose identity was often juxtaposed with that of stage Irish characters, and often performed by white Irish actors. In such a context, The Octoroon represents a form of continuity with what came before – and must therefore be seen in Irish as well as American contexts. Its impact on subsequent performance histories is also considered, up to and including the staging on the Abbey Theatre stage of An Octoroon – an adaptation of the original play – in 2022.
