Module summary

High medieval Europe saw a resurgence in the popularity of ‘heretical’ ideas. Unorthodox ideas have always circulated, but during the twelfth and thirteenth centuries they gathered momentum, and seemed to resonate with large numbers of people. Some of these ideas were straightforwardly concerned with questions of how to properly live a spiritual life; some asked deeper questions about the nature of god and the presence of evil in the world. At the same time, there were efforts to contain, control, and, increasingly, repress support for these movements. Those measures found their most acute expression with the establishment of inquisition, which in turn laid the foundations for a technology of power that would last well beyond the medieval period.

The module will interrogate the complex relationship between dissent and authority. It will examine this history through chronicles, letters, and polemical treatises and, after the establishment of inquisition tribunals in the 1230s, through inquisition documents. These include not only records of interrogations and the sentences handed down, but also inquisitors’ ‘how to’ manuals. Together, these records allow us to investigate why heretical ideas were popular, why heretics were supported in communities, and how religious dissent and religious intolerance acted upon each other. The pursuit of these topics in the original records goes hand in hand with the hard-fought debate over how to properly understand the relationship between heresy and repression, a debate that has been ongoing since the medieval period, between historians of various denominations, ideologies, and schools of thought.
