This intellectual history of the dissident Hussite reform movement in early fifteenth-century Bohemia explains the process of Hussite radicalization, which led to their overthrow of secular and religious structures in the so-called "first European revolution". It does so by uncovering the political relevance of diverse heterodox leaders and the discourses they adapted for mobilizing calls to conflict. As such, the work represents a reimagining of the Hussite revolution which emphasizes the symbolic worldview of its agents. This includes an appreciation of the Hussite debt to unexpected traditions of thought, and of the movement's participation in innovative visions of the theo-political order.
