Adam Mickiewicz’s Dziady (usually rendered in English as Forefathers’ Eve), a text every Pole studies in school, has been used to make strong cultural and political statements for decades. And, as in the States, a low-turnout election recently brought a right-wing nationalist government to power. So the new production of Dziady at the 2016 Theatre Olympics in Wrocław this past fall was potentially far more fraught than Hamilton became after Mike Pence saw it.
