This article examines the ways in which the crusades against the Hussites were launched. It provides a complete overview of papal bulls issued for the purpose of eradicating heresy in Bohemia and Moravia, and explores the relationship between the crusading bulls and specialized legations. In addition, it investigates the practical implementation of papal ordinances, which was the main task of the anti-Hussite legates. The response of the secular arm to the calls to crusade and the preaching campaigns depended on a number of political considerations, meaning that the dispatch of expeditions did not always correspond to papal proclamations. Recurrent military failures resulted in repeated calls to arms by secular authorities and a re-publishing of crusade bulls by papal agents.
