On July 10, 1941, as many as 1,600 Jewish men, women, and children were rounded up and packed into a barn in Jedwabne, a small town in northwest Poland. The locked barn was set ablaze, and everyone inside perished. The pogrom is notable (and controversial) because, unlike similar atrocities in Nazi-occupied cities and villages, the massacre was not carried out solely by officers of the Third Reich or by Soviet nationals. The perpetrators were friends, associates, and neighbors of the Jews with whom they had lived peaceably and side-by-side before the occupation. Although not explicitly about Jedwabne, Tadeusz Słobodzianek’s Our Class follows the basic outlines of the historical events, and under Igor Golyak’s resourceful and potent direction, the play shows that our most barbarous enemies may indeed dwell among us.
