Theatrical performance in the Terezín/Theresienstadt ghetto

What did theatrical performance mean to the prisoners of the World War II Jewish ghetto at Terezín/Theresienstadt? We often call it "spiritual resistance," but what did they call it, both in the ghetto itself and in more than sixty years of postwar testimony? What do the scripts they wrote reveal? In my dissertation and in an anthology of plays written in the ghetto I engage with the most basic question: why did the prisoners perform?
