The genre of political theatre spurred by the Vietnam War. Protests occurred around the globe as the war escalated in the mid-1960s, proving that isolationalism was no more and every country and issue was deeply connected. The "post-imperialist" age in which the war and arts were taking place created a ripe environment for political theatre to flourish.

In "Vietnam Protest Theatre: The television war on stage," Professor Nora Alter explores various examples of these plays and their cultural contexts, particularly from "England, Austria, Germany, and France, where plays about the Vietnam War often served as the occasion for critiques of these nations' current politics or their imperialist pasts."

Unfortunately, as with much political theatre, the "current event" nature of some of these plays, coupled with their radical content, made them quickly forgotten and abandoned by mainstream culture. Others, such as Hair, lived on as vivid examples of how art can touch universal nerves through charged moments in history.
