Theatre and war have long been bedfellows. This brief study looks beyond theatre that is about war, and instead focuses on the relationship between theatre and war: how they feed into and inform one another, from rehearsal to post-production analysis. The study builds on the premise that theatre and war share a deep kinship that finds its consummate expression in the very phrase -theatre of war.- This critical look at the entangled history of theatre and war asks pressing questions that remain pertinent to our current moment: how have the tools of theatre been used in the waging of war? How have the tools of waging war been used in the making of performance? What are the -shared interests- of theatre and war? And how has performance become a militarized paradigm?
