Johannes Czakai presented his ongoing research project on Jewish conversions to Christianity in early modern Silesia, a border region between actual and imagined borders – “East” and “West”, Germany, Poland and the Czech lands, Catholicism and Protestantism. Hundreds of Jews converted to Christianity but almost none of them left behind ego-documents. To uncover the history of this so far unknown and “speechless” group, he conducted detailed microstudies. Based on extensive archival research he reconstructed the biographies of several converts and illuminated how the coexistence of Jews, Christians, and converts in Silesia was closer than one could have expected. His research reveals so far unknown economic and spiritual networks and opens up a new perspective on the history of consumption by exploring the role of Jews and converts in the Silesian alcohol and meat production. He showed that changing faiths did not necessarily entail “radical assimilation” or resulted in “mingled identities” and “divided souls”. Instead, conversions were one of several options of agency.
