Theatre has played an important role in post-conflict northern Ireland, where it has been used by artists, communities, and organisations as a tool for political advocacy. This book provides an up-to-date assessment of the state of theatre in northern Ireland since the end of the conflict, across a period of complete transformation, from entrenched civil conflict to relative peace and prosperity. With a focus on applied theatre and works that use theatre as advocacy, the book investigates the ways the main communities in the region have used theatre to promote their agendas, combat prejudice, and deal with legacy issues of the conflict. It also explores the emergence of new theatres that reflect social and demographic changes in the post-conflict period, including theatre with migrants and minorities, LGBTQ and Irish language theatre. In doing so, it examines the crucial role that theatre (and by extension, arts) can play in processes of reconciliation. The book will prove valuable to students and academics in the fields of applied theatre, conflict studies, and arts for reconciliation. It will appeal also to the general reader with an interest in northern Irish politics and culture.
