The present volume explores the sometimes-ambivalent attitude of Dominicans – individually or as a group – towards the ideologies that have dominated Europe in the “short” twentieth century, such as nationalism, fascism, Nazism and communism. Did Dominicans propose strategies of resistance, accommodation or collaboration, and what was their underlying motivation for doing so? How did their stance affect the position of the order and the church, both on the local and the general level? How did this influence their self-understanding (ad intra) and their public image (ad extra)? Did this generate conflicts within the order? Were there long-term consequences, perhaps even until today? In short, how did they live up to the motto of the order, Veritas, in a context of diverse ideological claims to truth?
